The code you gave below for writing the bitmap makes several invalid assumptions about the bitmap format. Read up more about OS5 in general and PACE in particular to understand why what you're doing won't work. (PACE is the 68k emulator layer responsible for running your 68k-based app on the ARM-based OS5 device).
Read the "OS 5 High Density Overview and FAQ" in the PalmSource Knowledge Base. At least 5 of the topics in that contain information directly relevant to your issue, even though your issue isn't specifically about high density. It even has sample code to help you work with bitmaps that can be written to a database. I've run across several other KB and FAQ articles on this topic but I don't remember the links to them. Look them up yourself. Here's a brief summary to help you look in the right directions. Your code assumes that the bitmap structure is stored as a single contiguous chunk of memory, and that you have access to the raw bitmap data. Neither is necessarily true in OS5 anymore. > Code for writing the bitmap resource > ========================= > BitmapType *wowScratchBitmapP, *resBitmapP; > ... > WinHandle saveWinH = WinSaveBits ( &bounds , &err ); > .... > wowScratchBitmapP = WinGetBitmap ( saveWinH ); > ... > // open/create database to save > .... > // if resource already exist remove it using DmRemoveResource > ... > resH = DmNewResource (dbScratchRef, bitmapRsc, resID, BmpSize > (wowScratchBitmapP) ); > ... > resBitmapP = (BitmapType*) MemHandleLock (resH); > DmWrite ( resBitmapP, 0, wowScratchBitmapP, BmpSize (wowScratchBitmapP) ); > MemHandleUnlock (resH); > DmReleaseResource (resH); -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
