Jorrit,
The ANNOTATION layer is deprecated and might event be remove in
mapserver 6.4
Anyway if you just want to put an arbitrary label on an image You can
create a point layer and use FEATURE to define where you want the label
and use TEXT to define the text of the label.

Hi all,
I try draw an ANNOTATION type layer based on RASTER type layer. When
doing this based on a shape file I would set the LABEL item on the
ANNOTATION layer to be attribute used in the shapefile.
What LABELITEM should I use when using RASTER data?
I posted the Mapfile I have so far hereunder.
Thank you for your help.
Bye
Jorrit
