commit 9362c7ddd1af3b168953d0737877bc52d79c94f4
Author: Tobias Stoeckmann <tobias@stoeckmann.org>
Date: Sun Sep 25 21:43:09 2016 +0200
Validate lengths while parsing server data.
Individual lengths inside received server data can overflow
the previously reserved memory.
It is therefore important to validate every single length
field to not overflow the previously agreed sum of all invidual
length fields.
v2: consume remaining bytes in the reply buffer on error.

commit 8fad00b0b647ee662ce4737ca15be033b7a21714
Author: Tobias Stoeckmann <tobias@stoeckmann.org>
Date: Sun Sep 25 21:42:09 2016 +0200
Avoid OOB write in XRenderQueryFilters
The memory for filter names is reserved right after receiving the reply.
After that, filters are iterated and each individual filter name is
stored in that reserved memory.
The individual name lengths are not checked for validity, which means
that a malicious server can reserve less memory than it will write to
during each iteration.
v2: consume remaining bytes in reply buffer on error.

Fix request length calculation for XRenderCompositeText32
Request length calculation inside XRenderCompositeText32 is broken for
the case where the number of glyphs fits exactky inside the last
xGlyphElt.
In XRenderCompositeText8 and XRenderCompositeText16 this case is
handled properly, somehow the "-1" got missing in
XRenderCompositeText32.

Remove fallback for _XEatDataWords, require libX11 1.6 for it
_XEatDataWords was orignally introduced with the May 2013 security
patches, and in order to ease the process of delivering those,
fallback versions of _XEatDataWords were included in the X extension
library patches so they could be applied to older versions that didn't
have libX11 1.6 yet. Now that we're past that hurdle, we can drop
the fallbacks and just require libX11 1.6 for building new versions
of the extension libraries.

As an interim measure, replace AM_INIT_AUTOMAKE([dist-bzip2]) with
AM_INIT_AUTOMAKE([foreign dist-bzip2]). This will prevent the generation
of the INSTALL file. It is also part of the 24206 solution.

Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
2006, 2007, 2008 Free Software Foundation, Inc.
This file is free documentation; the Free Software Foundation gives
unlimited permission to copy, distribute and modify it.
Basic Installation
==================
Briefly, the shell commands `./configure; make; make install' should
configure, build, and install this package. The following
more-detailed instructions are generic; see the `README' file for
instructions specific to this package.
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions. Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, and a
file `config.log' containing compiler output (useful mainly for
debugging `configure').
It can also use an optional file (typically called `config.cache'
and enabled with `--cache-file=config.cache' or simply `-C') that saves
the results of its tests to speed up reconfiguring. Caching is
disabled by default to prevent problems with accidental use of stale
cache files.
If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release. If you are using the cache, and at
some point `config.cache' contains results you don't want to keep, you
may remove or edit it.
The file `configure.ac' (or `configure.in') is used to create
`configure' by a program called `autoconf'. You need `configure.ac' if
you want to change it or regenerate `configure' using a newer version
of `autoconf'.
The simplest way to compile this package is:
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system.
Running `configure' might take a while. While running, it prints
some messages telling which features it is checking for.
2. Type `make' to compile the package.
3. Optionally, type `make check' to run any self-tests that come with
the package.
4. Type `make install' to install the programs and any data files and
documentation.
5. You can remove the program binaries and object files from the
source code directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile the package for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
6. Often, you can also type `make uninstall' to remove the installed
files again.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that
the `configure' script does not know about. Run `./configure --help'
for details on some of the pertinent environment variables.
You can give `configure' initial values for configuration parameters
by setting variables in the command line or in the environment. Here
is an example:
./configure CC=c99 CFLAGS=-g LIBS=-lposix
*Note Defining Variables::, for more details.
Compiling For Multiple Architectures
====================================
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you can use GNU `make'. `cd' to the
directory where you want the object files and executables to go and run
the `configure' script. `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'.
With a non-GNU `make', it is safer to compile the package for one
architecture at a time in the source code directory. After you have
installed the package for one architecture, use `make distclean' before
reconfiguring for another architecture.
On MacOS X 10.5 and later systems, you can create libraries and
executables that work on multiple system types--known as "fat" or
"universal" binaries--by specifying multiple `-arch' options to the
compiler but only a single `-arch' option to the preprocessor. Like
this:
./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
CPP="gcc -E" CXXCPP="g++ -E"
This is not guaranteed to produce working output in all cases, you
may have to build one architecture at a time and combine the results
using the `lipo' tool if you have problems.
Installation Names
==================
By default, `make install' installs the package's commands under
`/usr/local/bin', include files under `/usr/local/include', etc. You
can specify an installation prefix other than `/usr/local' by giving
`configure' the option `--prefix=PREFIX'.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
pass the option `--exec-prefix=PREFIX' to `configure', the package uses
PREFIX as the prefix for installing programs and libraries.
Documentation and other data files still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like `--bindir=DIR' to specify different values for particular
kinds of files. Run `configure --help' for a list of the directories
you can set and what kinds of files go in them.
If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
Optional Features
=================
Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System). The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.
For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.
Particular systems
==================
On HP-UX, the default C compiler is not ANSI C compatible. If GNU
CC is not installed, it is recommended to use the following options in
order to use an ANSI C compiler:
./configure CC="cc -Ae"
and if that doesn't work, install pre-built binaries of GCC for HP-UX.
On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
parse its `<wchar.h>' header file. The option `-nodtk' can be used as
a workaround. If GNU CC is not installed, it is therefore recommended
to try
./configure CC="cc"
and if that doesn't work, try
./configure CC="cc -nodtk"
Specifying the System Type
==========================
There may be some features `configure' cannot figure out
automatically, but needs to determine by the type of machine the package
will run on. Usually, assuming the package is built to be run on the
_same_ architectures, `configure' can figure that out, but if it prints
a message saying it cannot guess the machine type, give it the
`--build=TYPE' option. TYPE can either be a short name for the system
type, such as `sun4', or a canonical name which has the form:
CPU-COMPANY-SYSTEM
where SYSTEM can have one of these forms:
OS KERNEL-OS
See the file `config.sub' for the possible values of each field. If
`config.sub' isn't included in this package, then this package doesn't
need to know the machine type.
If you are _building_ compiler tools for cross-compiling, you should
use the option `--target=TYPE' to select the type of system they will
produce code for.
If you want to _use_ a cross compiler, that generates code for a
platform different from the build platform, you should specify the
"host" platform (i.e., that on which the generated programs will
eventually be run) with `--host=TYPE'.
Sharing Defaults
================
If you want to set default values for `configure' scripts to share,
you can create a site shell script called `config.site' that gives
default values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists. Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: not all `configure' scripts look for a site script.
Defining Variables
==================
Variables not defined in a site shell script can be set in the
environment passed to `configure'. However, some packages may run
configure again during the build, and the customized values of these
variables may be lost. In order to avoid this problem, you should set
them in the `configure' command line, using `VAR=value'. For example:
./configure CC=/usr/local2/bin/gcc
causes the specified `gcc' to be used as the C compiler (unless it is
overridden in the site shell script).
Unfortunately, this technique does not work for `CONFIG_SHELL' due to
an Autoconf bug. Until the bug is fixed you can use this workaround:
CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
`configure' Invocation
======================
`configure' recognizes the following options to control how it
operates.
`--help'
`-h'
Print a summary of all of the options to `configure', and exit.
`--help=short'
`--help=recursive'
Print a summary of the options unique to this package's
`configure', and exit. The `short' variant lists options used
only in the top level, while the `recursive' variant lists options
also present in any nested packages.
`--version'
`-V'
Print the version of Autoconf used to generate the `configure'
script, and exit.
`--cache-file=FILE'
Enable the cache: use and save the results of the tests in FILE,
traditionally `config.cache'. FILE defaults to `/dev/null' to
disable caching.
`--config-cache'
`-C'
Alias for `--cache-file=config.cache'.
`--quiet'
`--silent'
`-q'
Do not print messages saying which checks are being made. To
suppress all normal output, redirect it to `/dev/null' (any error
messages will still be shown).
`--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
`configure' can determine that directory automatically.
`--prefix=DIR'
Use DIR as the installation prefix. *Note Installation Names::
for more details, including other options available for fine-tuning
the installation locations.
`--no-create'
`-n'
Run the configure checks, but stop before creating any output
files.
`configure' also accepts some other, not widely useful, options. Run
`configure --help' for more details.

## (see the conditional assignment to $gccflag above).
## There are various ways to get dependency output from gcc. Here's
## why we pick this rather obscure method:
## - Don't want to use -MD because we'd like the dependencies to end
## up in a subdir. Having to rename by hand is ugly.
## (We might end up doing this anyway to support other compilers.)
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
## -MM, not -M (despite what the docs say). Also, it might not be
## supported by the other compilers which use the 'gcc' depmode.
## - Using -M directly means running the compiler twice (even worse
## than renaming).

## This next piece of magic avoids the "deleted header file" problem.
## The problem is that when a header file which appears in a .P file
## is deleted, the dependency causes make to die (because there is
## typically no way to rebuild the header). We avoid this by adding
## dummy dependencies for each header file. Too bad gcc doesn't do
## this for us directly.
## Some versions of gcc put a space before the ':'. On the theory
## that the space means something, we add a space to the output as
## well. hp depmode also adds that space, but also prefixes the VPATH
## to the object. Take care to not repeat it in the output.
## Some versions of the HPUX 10.20 sed can't process this invocation

The Xrender Library
Version 0.7
2002-11-6
Keith Packard
keithp@xfree86.org
1. Introduction
The Xrender library is designed as a lightweight library interface to the
Render extension. This document describes how the library maps to the
protocol without duplicating the semantics described by that document.
2. Data Types
2.1 Primitive Types
For resources represented as CARD32 or XID on the wire, Xrender exposes them
using an 'unsigned long' type as is the norm for 32-bit data objects in an
Xlib compatible API.
typedef unsigned long Glyph;
typedef unsigned long GlyphSet;
typedef unsigned long Picture;
typedef unsigned long PictFormat;
Glyphs are just CARD32 objects, while GlyphSet, Picture and PictFormat
values are XIDs.
typedef int XFixed;
Fixed point numbers buck the Xlib convention by being represented as ints.
Machines for which 'int' is smaller than 32 bits cannot support the Xrender
library.
2.2 PictFormat descriptions.
The definition of a PictFormat is exposed by two data structures:
typedef struct {
short red;
short redMask;
short green;
short greenMask;
short blue;
short blueMask;
short alpha;
short alphaMask;
} XRenderDirectFormat;
typedef struct {
PictFormat id;
int type;
int depth;
XRenderDirectFormat direct;
Colormap colormap;
} XRenderPictFormat;
These serve both as a description of the available formats and as patterns
against which available formats are matched.
2.3 Picture Attributes
When creating or changing Picture objects, attributes are passed much as
they are for XCreateWindow/XChangeWindowAttributes. A structure capable of
holding all of the attributes has the relevant ones set and a bitmask passed
as a separate argument which marks the valid entries.
typedef struct _XRenderPictureAttributes {
Bool repeat;
Picture alpha_map;
int alpha_x_origin;
int alpha_y_origin;
int clip_x_origin;
int clip_y_origin;
Pixmap clip_mask;
Bool graphics_exposures;
int subwindow_mode;
int poly_edge;
int poly_mode;
Atom dither;
Bool component_alpha;
} XRenderPictureAttributes;
2.4 Colors
The core protocol XColor type doesn't include an alpha component, so Xrender
has a separate type. Note that XRender expects premultiplied alpha in all
cases except with the gradient operations.
typedef struct {
unsigned short red;
unsigned short green;
unsigned short blue;
unsigned short alpha;
} XRenderColor;
2.5 Glyph Types
Glyphs are stored in the server, so these definitions are passed from the
client to the library and on to the server as glyphs are rasterized and
transmitted over the wire.
typedef struct _XGlyphInfo {
unsigned short width;
unsigned short height;
short x;
short y;
short xOff;
short yOff;
} XGlyphInfo;
2.6 Glyph Rendering types
Glyph rendering can either take a single string of glyph indices or an array
of one of the following structures.
typedef struct _XGlyphElt8 {
GlyphSet glyphset;
_Xconst char *chars;
int nchars;
int xOff;
int yOff;
} XGlyphElt8;
typedef struct _XGlyphElt16 {
GlyphSet glyphset;
_Xconst unsigned short *chars;
int nchars;
int xOff;
int yOff;
} XGlyphElt16;
typedef struct _XGlyphElt32 {
GlyphSet glyphset;
_Xconst unsigned int *chars;
int nchars;
int xOff;
int yOff;
} XGlyphElt32;
2.7 Geometric Types
Geometric operations directly expose the available protocol datatypes
typedef struct _XPointFixed {
XFixed x, y;
} XPointFixed;
typedef struct _XLineFixed {
XPointFixed p1, p2;
} XLineFixed;
typedef struct _XTriangle {
XPointFixed p1, p2, p3;
} XTriangle;
typedef struct _XTrapezoid {
XFixed top, bottom;
XLineFixed left, right;
} XTrapezoid;
typedef struct _XTransform {
XFixed matrix[3][3];
} XTransform;
2.8 Transformation Filters
All of the filters are named simultaneously; Xrender provides no convenience
functions for dealing with them.
typedef struct _XFilters {
int nfilter;
char **filter;
int nalias;
short *alias;
} XFilters;
2.9 Index type PictFormat colors
PictFormats of Index type advertise which colors will be used for drawing
through this type.
typedef struct _XIndexValue {
unsigned long pixel;
unsigned short red, green, blue, alpha;
} XIndexValue;
3 Application Startup Functions
3.1 Initialization functions
Bool XRenderQueryExtension (Display *dpy,
int *event_basep,
int *error_basep)
This function returns True if the Render extension is available on dpy.
event_basep and error_basep will be filled in with the first event and error
numbers used by the extension (note that Render currently uses no events).
Status XRenderQueryVersion (Display *dpy,
int *major_versionp,
int *minor_versionp)
XRenderQueryVersion returns zero if the Render extension is not present or
some error occurred while attempting to discover the current Render version
number. Otherwise, XRenderQueryVersion returns 1 and stores the version
number returned by the server in *major_versionp and *minor_versionp, which
will be less than or equal to the library version numbers RENDER_MAJOR and
RENDER_MINOR.
Status XRenderQueryFormats (Display *dpy)
XRenderQueryFormats returns 1 if it successfully fetches the available
PictFormat information from the X server, 0 otherwise. Applications needn't
invoke this function directly (hmm, perhaps it should be removed from the
external interfaces then).
3.2 Subpixel Order
int XRenderQuerySubpixelOrder (Display *dpy, int screen)
Bool XRenderSetSubpixelOrder (Display *dpy, int screen, int subpixel)
Applications interested in the geometry of the elements making up a single
pixel on the screen should use XRenderQuerySubpixelOrder and not cache the
return value. XRenderSetSubpixelOrder is used by the XRandR library to
update the value stored by Xrender when the subpixel order changes as a
result of screen reconfiguration.
3.3 PictFormat matching
Xrender provides these APIs to help locate appropriate PictFormats; they are
intended to work much like the Visual matching APIs in Xlib. The
application provides a specification including the necessary PictFormat
characteristics and Xrender returns a matching XRenderPictFormat structure
which describes the PictFormat.
XRenderPictFormat *
XRenderFindFormat (Display *dpy,
unsigned long mask,
_Xconst XRenderPictFormat *templ,
int count)
#define PictFormatID (1 << 0)
#define PictFormatType (1 << 1)
#define PictFormatDepth (1 << 2)
#define PictFormatRed (1 << 3)
#define PictFormatRedMask (1 << 4)
#define PictFormatGreen (1 << 5)
#define PictFormatGreenMask (1 << 6)
#define PictFormatBlue (1 << 7)
#define PictFormatBlueMask (1 << 8)
#define PictFormatAlpha (1 << 9)
#define PictFormatAlphaMask (1 << 10)
#define PictFormatColormap (1 << 11)
XRenderFindFormat locates a PictFormat matching the characteristics provided
in the templ. Only elements whose associated bit in mask are compared.
XRenderPictFormat *
XRenderFindVisualFormat (Display *dpy, _Xconst Visual *visual)
Finds the PictFormat suitable for use with the specified visual.
XRenderPictFormat *
XRenderFindStandardFormat (Display *dpy,
int format)
#define PictStandardARGB32 0
#define PictStandardRGB24 1
#define PictStandardA8 2
#define PictStandardA4 3
#define PictStandardA1 4
#define PictStandardNUM 5
As a convenience, this function locates PictFormats that correspond to
commonly used formats.
ARGB32 depth 32, bits 31-24 A, 23-16 R, 15-8 G, 7-0 B
RGB24 depth 24, bits 23-16 R, 15-8 G, 7-0 B
A8 depth 8, bits 7-0 A
A4 depth 4, bits 3-0 A
A1 depth 1, bits 0 A
Any server supporting Render must have a PictFormat corresponding to each of
these standard formats.
3.4 Index type PictFormat color values
XIndexValue *
XRenderQueryPictIndexValues(Display *dpy,
_Xconst XRenderPictFormat *format,
int *num)
If format refers to an Index type PictFormat, XRenderQueryPictIndexValues
returns the set of pixel values and their associated colors used when
drawing to Pictures created with that format. Otherwise,
XRenderQueryPictIndexValues generates a BadMatch error.
3.5 Querying available filters
XFilters *
XRenderQueryFilters (Display *dpy, Drawable drawable);
Filters are used with non-identity transformation matrices, this function
returns a datastructure identifying the available filters on display that
can be associated with pictures for the screen associated with drawable.
Free this structure with XFree.
4 Picture Functions
Picture
XRenderCreatePicture (Display *dpy,
Drawable drawable,
_Xconst XRenderPictFormat *format,
unsigned long valuemask,
_Xconst XRenderPictureAttributes *attributes)
#define CPRepeat (1 << 0)
#define CPAlphaMap (1 << 1)
#define CPAlphaXOrigin (1 << 2)
#define CPAlphaYOrigin (1 << 3)
#define CPClipXOrigin (1 << 4)
#define CPClipYOrigin (1 << 5)
#define CPClipMask (1 << 6)
#define CPGraphicsExposure (1 << 7)
#define CPSubwindowMode (1 << 8)
#define CPPolyEdge (1 << 9)
#define CPPolyMode (1 << 10)
#define CPDither (1 << 11)
#define CPComponentAlpha (1 << 12)
#define CPLastBit 12
Creates a picture for drawable in the specified format. Any values
specified in 'attributes' and 'valuemask' are used in place of the default
values.
void
XRenderChangePicture (Display *dpy,
Picture picture,
unsigned long valuemask,
_Xconst XRenderPictureAttributes *attributes)
Change values in picture to those specified by valuemask and attributes.
void
XRenderSetPictureClipRectangles (Display *dpy,
Picture picture,
int xOrigin,
int yOrigin,
_Xconst XRectangle *rects,
int n)
Sets the clip mask in picture to the union of rects offset by
xOrigin/yOrigin.
void
XRenderSetPictureClipRegion (Display *dpy,
Picture picture,
Region r)
Sets the clip mask in picture to r.
void
XRenderSetPictureTransform (Display *dpy,
Picture picture,
XTransform *transform)
Sets the projective transformation matrix of picture to transform.
void
XRenderFreePicture (Display *dpy,
Picture picture)
Instructs the server to free picture.
5 GlyphSet functions
GlyphSet
XRenderCreateGlyphSet (Display *dpy, _Xconst XRenderPictFormat *format)
Creates a glyphset, every glyph in the set will use PictFormat format.
GlyphSet
XRenderReferenceGlyphSet (Display *dpy, GlyphSet existing)
Creates a new GlyphSet ID which references an existing GlyphSet. The
two IDs refer to the same object so that changes using one ID will be
visible through the other ID. This is designed to allow multiple clients to
share the same GlyphSet so that it doesn't get destroyed when the first
client exits.
void
XRenderFreeGlyphSet (Display *dpy, GlyphSet glyphset)
Frees the glyphset ID. If no other GlyphSet IDs refer to the underlying
GlyphSet, it will be destroyed.
void
XRenderAddGlyphs (Display *dpy,
GlyphSet glyphset,
_Xconst Glyph *gids,
_Xconst XGlyphInfo *glyphs,
int nglyphs,
_Xconst char *images,
int nbyte_images)
Add glyphs to glyphset. The images are packed together in Z-pixmap format
according to the depth of the PictFormat used in creating glyphset.
void
XRenderFreeGlyphs (Display *dpy,
GlyphSet glyphset,
_Xconst Glyph *gids,
int nglyphs)
Free some glyphs from glyphset.
6 Glyph Drawing Routines
Xrender provides two parallel APIs for glyph rendering, a simple API which
accepts a single string similar to XDrawString and a more complex API which
accepts an array of XGlyphElt{8,16,32} structures, each of which includes a
glyphset, string and x/y offsets which parallel the XDrawText API. Xrender
also provides glyphs in three sizes, 8 16 and 32 bits. The simple API is
just a convenience for the user as both forms generate the same underlying
Render protocol.
6.1 Simple single-string glyph drawing functions
These are identical except for the format of the glyph ids.
void
XRenderCompositeString8 (Display *dpy,
int op,
Picture src,
Picture dst,
_Xconst XRenderPictFormat *maskFormat,
GlyphSet glyphset,
int xSrc,
int ySrc,
int xDst,
int yDst,
_Xconst char *string,
int nchar)
void
XRenderCompositeString16 (Display *dpy,
int op,
Picture src,
Picture dst,
_Xconst XRenderPictFormat *maskFormat,
GlyphSet glyphset,
int xSrc,
int ySrc,
int xDst,
int yDst,
_Xconst unsigned short *string,
int nchar)
void
XRenderCompositeString32 (Display *dpy,
int op,
Picture src,
Picture dst,
_Xconst XRenderPictFormat *maskFormat,
GlyphSet glyphset,
int xSrc,
int ySrc,
int xDst,
int yDst,
_Xconst unsigned int *string,
int nchar)
6.2 Complete glyph drawing functions
As with the simple functions above, these differ only in the type of the
underlying glyph id storage type.
void
XRenderCompositeText8 (Display *dpy,
int op,
Picture src,
Picture dst,
_Xconst XRenderPictFormat *maskFormat,
int xSrc,
int ySrc,
int xDst,
int yDst,
_Xconst XGlyphElt8 *elts,
int nelt)
void
XRenderCompositeText16 (Display *dpy,
int op,
Picture src,
Picture dst,
_Xconst XRenderPictFormat *maskFormat,
int xSrc,
int ySrc,
int xDst,
int yDst,
_Xconst XGlyphElt16 *elts,
int nelt)
void
XRenderCompositeText32 (Display *dpy,
int op,
Picture src,
Picture dst,
_Xconst XRenderPictFormat *maskFormat,
int xSrc,
int ySrc,
int xDst,
int yDst,
_Xconst XGlyphElt32 *elts,
int nelt)
7 Basic Graphics Functions
These are the simplest graphics functions upon which the other functions are
conceptually built.
7.1 Composite
XRenderComposite exposes the RenderComposite protocol request directly.
If a format with alpha is used, make sure it is premultiplied into the
color channels.
void
XRenderComposite (Display *dpy,
int op,
Picture src,
Picture mask,
Picture dst,
int src_x,
int src_y,
int mask_x,
int mask_y,
int dst_x,
int dst_y,
unsigned int width,
unsigned int height)
7.2 Rectangles
These functions composite rectangles of the specified color, they differ
only in that XRenderFillRectangles draws more than one at a time.
void
XRenderFillRectangle (Display *dpy,
int op,
Picture dst,
_Xconst XRenderColor *color,
int x,
int y,
unsigned int width,
unsigned int height)
void
XRenderFillRectangles (Display *dpy,
int op,
Picture dst,
_Xconst XRenderColor *color,
_Xconst XRectangle *rectangles,
int n_rects)
8 Geometric Objects
All geometric drawing with Render is performed with sequences of trapezoids
or triangles; the client is responsible for breaking more complex figures
into these simple shapes.
8.1 Trapezoids
void
XRenderCompositeTrapezoids (Display *dpy,
int op,
Picture src,
Picture dst,
_Xconst XRenderPictFormat *maskFormat,
int xSrc,
int ySrc,
_Xconst XTrapezoid *traps,
int ntrap)
XRenderCompositeTrapezoids builds RenderTrapezoids requests to composite the
specified list of trapezoids to dst. XRenderCompositeTrapezoids will split
the list of trapezoids to build requests no larger than the maximum request
size supported by the server. This can create rendering artifacts as the
precompositing done by RenderTrapezoids when a maskFormat is specified
cannot span multiple requests.
8.2 Triangles
Render provides three different ways of encoding triangles on the wire,
Xrender exposes those with three separate triangle drawing routines. As
with trapezoids above, Xrender will split the arguments to fit requests into
the servers limits, but this may cause rendering artifacts.
