As it looks, you can define your own fill patterns and save them with your IMG-file. As you may know, standard fill patterns are 16 pixel wide, so it's the 2 for two bytes. > >>1 word pixel width in microns (1/1000 mm, 25400 microns per inch) >>1 word pixel height in microns > > Does most software actually take this into account for anything >or can you leaave the pixel dimension 0? When you are using your ATARI for publishing, you will need this information for restoring the original size of your IMG. In CALAMUS (SL Version is on the run since this week) you have a function for restoring this, but it will only work, if you have inserted the correct data. Please do so.
