vipsedit - edit header of a vips image file

vipsedit [OPTION...] vipsfile

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!

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

returns 0 on success and non-zero on error.
