6 mogrify - resize an image, blur, crop, despeckle, dither, draw on,

14 The mogrify program is a member of the ImageMagick(1) suite of tools.
15 Use it to resize an image, blur, crop, despeckle, dither, draw on,
16 flip, join, re-sample, and much more. This tool is similar to con‐
17 vert(1) except the original image file is overwritten with any changes
18 you request.

341 By default, the image format of `file' is determined by its magic num‐

344 an image format name and a colon (i.e. ps:image) or specify the image
345 type as the filename suffix (i.e. image.ps). Specify 'file' as '-' for
346 standard input or output.
