.TH mogrify 1 "Date: 2009/01/10 01:00:00" "ImageMagick" .SH 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. .SH SYNOPSIS .TP \fBmagick mogrify\fP [\fIoptions\fP] \fIinput-file\fP .SH OVERVIEW The \fBmogrify\fP 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. For more information about the mogrify command, point your browser to file:///opt/alt/alt-ImageMagick/usr/share/doc/ImageMagick-7/www/mogrify.html or https://imagemagick.org/script/mogrify.php. .SH
