Hello all...
I'm (again) experiencing troubles uncompressing bitmaps. My app
is opening bitmaps that have been created on another device. It
gets them in a database. They can be compressed in multiple
formats (i.e. scanline, RLE, packbits).
On a 3.5 ROM with an RLE compressed bitmap it works
of the header is changed to
BitmapCompressionTypeNone, the bitmap data remains that same.
I've had other problems uncompressing bitmaps, like BmpBitsSize
returning different values depending on the PalmOS version of
the device it is running on. This process seems like it should
either be easier or better

that is big enough to uncompress into, copy the data in,
and then call BmpCompress with BitmapCompressionTypeNone.
Nothing jumps out after a quick read. I use similar code and it works
for me. Sorry that doesn't help much.

I am trying to uncompress a Bitmap using the BmpCompress function. I am using CW R6
With 3.5 SDK. The problem I am having is the BMPCompress function is returning
sysErrNoFreeResource I don't know what would cause this error. The function works
fine on Bitmaps that are the size of the screen
