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.
