So sci companion has no issues rendering resource files for sci1 compatible games which use the vector based rendering and priorities. But for later sci1.1 and sci2 when sci starts using bmp style backgrounds, it has no way of saving the draw cells from the priority map?
Considering how the priority and control maps work...
In the original SCI 0.0 and 0.1, you had three bitmaps (visual, priority, control), painted in by vector commands. These can be freely edited in SCI Companion.
SCI 1.0 added a "draw image" command which painted a bitmap in the same format as a single View cel to the visual bitmap, but you could
still draw on the visual bitmap in the old style, just in 256 colors instead of 16, and there was no more dithering. Some SQ4 screens are entirely vector-drawn, and the Jones game board has its inside border drawn that way. All of this also goes for the 16-color SCI 1.0 games. This is why most SCI 1.0 Picture resources have one big "draw image" command and then draw the priority and control bitmaps the old way.
Around SCI 1.1, the control bitmap was
deprecated -- you could still use it, but the later games used Polygon objects exclusively for both walkable areas and Feature hotspots.
In SCI 2.0, the control bitmap was
removed, along with
every single vector drawing command. You could no longer directly draw on the priority bitmap; instead each layer of the image would have its own "draw image" command, with a position and priority value:
So what SCI Companion needs to properly and fully support SCI 2.x Picture resources is a way to change these position and priority values.
It seems that when I pull up resources from a game like QFG4 and pull up the pic file, the priority map is shown and recognized by sci companion. But when I export / save that resource as a patch file it is corrupted. My thoughts were maybe it was a conversion issue from p26 p56 but I was not sure.
There was a bug involving exported pics that may be in play here. Past tense.
