\-virtual-pixel method virtual pixel access method \-window id display image to background of this window \-window-group id exit program when this window id is destroyed \-write filename write image to a file Image Operators: \-auto-orient automatically orient image \-border geometry surround image with a border of color \-clip clip along the first path from the 8BIM profile \-clip-path id clip along a named path from the 8BIM profile \-colors value preferred number of colors in the image \-contrast enhance or reduce the image contrast \-crop geometry preferred size and location of the cropped image \-despeckle reduce the speckles within an image \-edge factor apply a filter to detect edges in the image \-enhance apply a digital filter to enhance a noisy image \-extract geometry extract area from image \-flip flip image in the vertical direction \-flop flop image in the horizontal direction \-frame geometry surround image with an ornamental border \-gamma value level of gamma correction \-monochrome transform image to black and white \-negate replace each pixel with its complementary color \-normalize transform image to span the full range of colors \-raise value lighten/darken image edges to create a 3-D effect \-resample geometry change the resolution of an image \-resize geometry resize the image \-roll geometry roll an image vertically or horizontally

profiles and comments \-threshold value threshold the image \-thumbnail geometry create a thumbnail of the image \-trim trim image edges Image Sequence Operators: \-coalesce merge a sequence of images \-flatten flatten a sequence of images Miscellaneous Options: \-debug events display copious debugging information \-help print program options \-log format format of debugging information \-list type print a list of supported option arguments \-version print version information In addition to those listed above, you can specify these standard X resources as command line options: \-background, \-bordercolor, \-borderwidth, \-font, \-foreground, \-iconGeometry, \-iconic, \-mattecolor, \-name, \-shared-memory, \-usePixmap, or \-title. By default, the image format of `file' is determined by its magic number. To specify a particular image format, precede the filename with an image format name and a colon (i.e. ps:image) or specify the image type as the filename suffix (i.e. image.ps). Specify 'file' as '-' for standard input or output. Buttons: 1 press to map or unmap the Command widget 2 press and drag to magnify a region of an image 3 press to load an image from a visual image directory .SH NOTE The display program defaults to the X screen resolution. To display vector formats at their intended size, override the default resolution: display -density 72 drawing.svg .SH SEE ALSO ImageMagick(1) .SH COPYRIGHT \fBCopyright (C) 1999-2020 ImageMagick Studio LLC.
