Support for some of these formats require additional programs or libraries. README tells where to find this software.
Note, a format delineated with + means that if more than one image is specified, it is combined into a single multi-image file. Use +adjoin if you want a single image produced for each frame.
Raw images are expected to have one byte per pixel unless ImageMagick is compiled in 16-bit mode. Here, the raw data is expected to be stored two bytes per pixel in most-significant-byte-first order.
Note, options -dither, -colorspace, and -treedepth affect the color reduction algorithm.
The Transparent color space behaves uniquely in that it preserves the matte channel of the image if it exists.
The -colors or -monochrome option is required for this option to take effect.
-comment "%m:%f %wx%h"
This option is useful for regulating the animation of GIF images within Netscape.. 1/100ths of a second must expire before the display of the next image. The default is no delay between each showing of the image sequence. The maximum delay is 65535.
0 No disposal specified. 1 Do not dispose. 2 Restore to background color. 3 Restore to previous.

Use image to composite an image with another image. Follow the image coordinates with the filename of an image.
You can set the primitive color, font color, and font bounding box color with -pen, -font, and -box respectively. Options are processed in command line order so be sure to use -pen before the -draw option.
Convert contacts an X server to obtain the font. If an X server is not available (e.g. screen locked), a Postscript font is used instead. You can set the pointsize with -pointsize.
Use > to change the dimensions of the image only if its size exceeds the geometry specification. < resizes the image only if its dimensions is less than the geometry specification. For example, if you specify 640x480> and the image size is 512x512, the image size does not change. However, if the image is 1024x1024, it is resized to 640x480.

There are 72 pixels per inch in PostScript coordinates.

Use an optional index enclosed in brackets after a file name to specify a desired subimage of a multi-resolution image format like Photo CD (e.g. img0001.pcd[4]) or a range for MPEG images (e.g. video.mpg[50-75]). A subimage specification can be disjoint (e.g. image.tiff[2,7,4]). For raw images, specify a subimage with a geometry (e.g. -size 640x512 image.rgb[320x256+50+50]).
converts files image00.miff, image01.miff, etc.
The fuzzy c-Means algorithm can be summarized as follows:
The fuzzy c-Means technique attempts to cluster a pixel by finding the local minima of the generalized within group sum of squared error objective function. A pixel is assigned to the closest class of which the fuzzy membership has a maximum value.
