mogrify(1)

NAME

mogrify - resize an image, blur, crop, despeckle, dither, draw on, flip, join, re-sample, and much more. Mogrify overwrites the original image file, whereas, convert(1) writes to a different image file.

SYNOPSIS

mogrify [options] input-file

OVERVIEW

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

Specify 'file' as '-' for standard input or output.
