| .SH NAME |
| edvips \- edit header of a vips image file |
| .SH SYNOPSIS |
| .B edvips [OPTION...] vipsfile |
| .SH DESCRIPTION |
| .B 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 |

| -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! |
| |
| .SH 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 |
| .B header(1), |
| edit it, and reattach with |
| .B edvips(1). |
| |
