NAME
       edvips - edit header of a vips image file

SYNOPSIS
       edvips [OPTION...] vipsfile

DESCRIPTION
       edvips 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. edvips does no checking!

EXAMPLES
       To set the Xsize to 512 and Bands to 6:

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

       or

	 edvips -x 512 -b 6 fred.v

       Extract the XML metadata from an image with header(1), edit it, and reattach with edvips(1).

	 header -f getext fred.v | sed s/banana/pineapple/ | edvips -e fred.v

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