Here's what I've tried: 1) Opening a CGrafPort and a picture, doing a CopyBits from the port to itself, closing the picture, and saving it to disk. For a 640x480 picture, this bombs during the CopyBits, even with 5M of memory, whether I've called MaxApplZone or not. QuickerGraf is enabled, for what that's worth. 2) Same as (1), but CopyBitsing in bands. This works perfectly, even when all the CopyBits are wrapped in a single picture, but it doubtless makes a larger PICT file than necessary, and it definitely takes longer to draw than... 3) Same as (1), only change the port's grafProcs to one that's been initialized with SetStdCProcs, and change the grafProcs' putPicProc as per IM5. (LSC bug: a CGrafPort's grafProcs is defined as a QDProcsPtr instead of a CQDProcsPtr.) This is pretty much straight from IM5, so I doubt I've messed this up. This also works perfectly, and gets me a much smaller PICT file than (2), but the color table is all wrong. This is true even if I use an OpenCPort to open both the port I'm copying from when I make the file and the one I'm copying to when I display it, or if I use another program to display the PICT file. Also, for fairly small rectangles (say 10x10), an application that tries to display the PICT file locks, but I suspect this is an independent bug. Although I'd like to know why (1) bombs and (2) doesn't, I'd really like to spool the pictures instead of doing (1) or (2) since I want them on disk anyway and I don't want to need a half meg MF partition. Has anybody done (3) successfully, for color pictures? --------------------------------------------------------------------------- Oliver Steele ...!decnet!mcnc!unc!steele UNC-CH steele@cs.unc.edu "We made it structured, and now it doesn't work." -- Brice Tebbs
