I am writing an interactive program to control a color scanner. Once I get the image scanned into memory I can scroll it on the Apollo display and do some simple editing. I can also save the image to a GPR bitmap file with the GPR_$OPEN_BITMAP_FILE call and then continue scanning/editing images. Here's my problem ... how do I close the bitmap file so the image which was just saved can be printed (copied, worked on by other people, etc) without exiting from my GPR program? I want to be able to continue working without my limited DN3000 address space getting filled up with bitmaps that have been previously written to disk. I seem to remember someone asking a similar question a while ago, but I can't recall the replies. -- David Krowitz krowitz@richter.mit.edu (18.83.0.109) krowitz%richter@eddie.mit.edu krowitz%richter@athena.mit.edu krowitz%richter.mit.edu@mitvma.bitnet (in order of decreasing preference)

Use gpr_$deallocate_bitmap (bitmap_desc, &status); /* C */ /Ollie Jones (speaking for myself, not necessarily for Apollo Computer, Inc.)
