edvips: edit header of a vips image file

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. IM_BANDFMT_UCHAR) -t, --type=T set Type to T (eg. IM_TYPE_XYZ) -c, --coding=C set Coding to C (eg. IM_CODING_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.
