.SH "خلاصه دستور (SYNOPSIS)"
.B vipsedit [OPTION...] vipsfile
.SH "توضیحات (DESCRIPTION)"
.B vipsedit 
alters a VIPS image file's header. This is useful for setting the resolution, 
for example.

The options are:

  -x, --xsize=N       set Xsize to N
  -y, --ysize=N       set Ysize to N
  -b, --bands=N       set Bands to N
  -f, --format=F      set BandFmt to F (eg. uchar)
  -i, --interpretation=I        
                      set Interpretation to I (eg. xyz)
  -c, --coding=C      set Coding to C (eg. labq)
  -X, --xres=R        set Xres to R pixels/mm
  -Y, --yres=R        set Yres to R pixels/mm
  -u, --xoffset=N     set Xoffset to N
  -v, --yoffset=N     set Yoffset to N
  -e, --setext        replace extension block with stdin

Be very careful when changing Xsize, Ysize, BandFmt or Bands. vipsedit does no
checking!

.SH "مثال‌ها (EXAMPLES)"
To set the Xsize to 512 and Bands to 6:

  vipsedit --xsize=512 --bands=6 fred.v

or

  vipsedit -x 512 -b 6 fred.v

Extract the XML metadata from an image with
.B vipsheader(1),
edit it, and reattach with 
.B vipsedit(1).

  vipsheader -f getext fred.v | sed s/banana/pineapple/ | vipsedit -e fred.v

.SH RETURN VALUE
returns 0 on success and non-zero on error.
