Image Operators: -auto-orient automagically 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 -decipher filename convert cipher pixels to plain pixels -deskew threshold straighten an 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 -equalize perform histogram equalization to an 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 -fuzz distance colors within this distance are considered equal -gamma value level of gamma correction -monochrome transform image to black and white -negate replace every 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 -rotate degrees apply Paeth rotation to the image -sample geometry scale image with pixel sampling -segment value segment an image -sharpen geometry sharpen the image -strip strip image of all 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 -list type print a list of supported option arguments -log format format of debugging information -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
