- Hello khoros group. I have a few questions relating to overlays,
- annotations etc.
- 1. I have numerous image files, and annotation files, with one
- annotation file per image. I want to combine the annotations with the
- images. At the moment, I can do this by going into editimage, reading
- in the annotations and using COMBINE OVERLAYS. But, is there any way
- to do this from the command line, without going in to editimage. The
- ideal way for me would be to turn the ascii annotation file into an
- image file and use the -ov argument to editimage, or just to combine
- the two files (e.g., with vadd or vand). However, in order to do this
- I need to get the ascii annotation file interpreted as an image.
- Therefore, is there any way either to get the annotation file into
- editimage from the CLUI (some sort of -ann option, which appears not
- to exist) or else to translate the annotation file into an image file.
-
- 2. At the moment I use COMBINE OVERLAYs within editimage, and write
- out the resulting file. This always appears to be of type byte, even
- when the input to editimage was short. Is this because COMBINE gets
- the image *as displayed* and I am working with an 8 bit screen? Is
- there any way I can get the combined data out with as much resolution
- as the input data. The transfer to byte is not a real problem for
- this application, but it's a pity to lose resolution if I can avoid
- it.
-
- Many thanks for all your help.
