% ConjureImageCommand() describes the format and characteristics of one or

% more image files. It will also report if an image is incomplete or corrupt.

% The information displayed includes the scene number, the file name, the
|
|||
|
|
% width and height of the image, whether the image is colormapped or not,
|
|||
|
|
% the number of colors in the image, the number of bytes in the image, the
|
|||
|
|
% format of the image (JPEG, PNM, etc.), and finally the number of seconds
|
|||
|
|
% it took to read and process the image.
|
|||
|
|
%
|

|

%

% o image_info: the image info.

%
