Anyone know why an Impress file that works fine on an old Imagen 240 per
model might break with "IVM error: Get/Put/Read out of bounds" followed
by an "IVM error: Internal state (6)" on a new 300 per Imagen?
I mean, I'm not doing anything fancy, just a 1000x1000 glyph... I was
hoping to hear something like: "you have to set the hv system now" or
something systematic. File and/or program is available on request...

From: David Fuchs <DRF@su-score.arpa> We had problems with 512x512 glyphs on the Imagen 300. After some initial confusion, the friendly folks at customer support say that this is a bug in the 2.1 firmware. It is still annoying that the machine can't give better error messages, at least so that you could tell the difference between your own software's errors and the Imagen's internal foul-ups. The dreaded, cryptic "IVM error" just won't do. -david -------

Thanks to DRF@su-score.ARPA for independant confirmation of the problem.
I broke the plot up into 64 characters, each 128 by 128 pixels, and typeset
them in the right spots, and it all works fine now...

From: Christopher Schmidt <SCHMIDT@sumex-aim.arpa> For bitmaps, I am inclined to use the impress opcode BITMAP. The downside is, you can only position the bitmap to within 32 pixels, but on the upside, you can get the printer to magnify it 1, 2, or 4 times. For 808 * 1024 images, for example, I just invoke magnification of 2. Note, however, that if you put the origin at the lower left hand corner of the page (by moving the pen there and executing SET-HV-SYSTEM(3 3 4)) you will find that you have to specify the scan lines from the bottom up instead of the top down. The same is true if you SET-HV-SYSTEM(0 3 5) to get a landscape HV system with the origin in the "lower left." --Christopher -------
