Zimmerman" (IBD) Subject: MOVIE.BYU We have a software interface for a Tektronix 4113B for MOVIE.BYU. Unfortunately, we don't seem to have the correct libraries to make the thing useful. The missing library subroutines are grstrt txade txqual window vwport txtclr move clrmap setpvw setpbm cmd1x int1x cmopen grstop cmclos text pxlwrt end1x. If you recognize the library and can tell me how to get a copy, please send me a message on the net. These routines are not in the PLOT-10 library (level 3.0).

I was wondering if you might be able to help me with a couple of questions. 1. We have a III FR80/A color microfilmer system. We normally use it via our CDC mainframes by way of 1600bpi mag tape. What we would like to do is be able to process files from a MacIntosh (Macpaint, Macdraw, etc.) and/or other micro systems, transfer them to our mainframes (using CDC's CONNECT product, which can transfer a micro file in straight binary), then translate the micro data format to micorfilmer format. The problem is, I haven't been able to locate any description of how the micro files are formatted. I presume they are in some sort of compacted raster format but it's not obvious looking at dumps. Do you or any people on the list know something about this? 2. Again regarding the microfilmer, one of the tricky aspects is performing accurate color correction (a.k.a "gamma" correction). I have a reasonably good scheme in place but it presumes the primary colors (RGB) are independent of each other, and that's not the case. but it involves taking about 300 measurements on a densitometer then doing a 3-dimensional curve fit for each primary. Was wondering if you or folks on the list have better solutions, or can just point me to published articles describing full-blown gamma correction?
