.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
\fBmogrify\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.

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.
