SYNOPSIS

vipsedit [OPTION...] vipsfile

DESCRIPTION

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!

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 vipsheader(1), edit it, and reattach with vipsedit(1).

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

RETURN VALUE

returns 0 on success and non-zero on error.
