any clue ??

Ok for the allocation, still resulting in seg fault. I use the version 3.40 of the library, is there a newer ?? Or is this bug not present in older versions ??

Ok, so the first problem is solved. But it remains one, i work on a image compression program so this is what I need to do :

1) compress an unsigned char * buffer in PNG format into a memory buffer (using GFL_BITMAP & gflSaveBitmapIntoMemory) (seems to work)
2) From the PNG bitstream, retrieve the ...

Ok, seems to work correctly now. Thank you !! I will contact you in case of further issues.

ok thank you, i will try this now ....

Ok, so i create an GFL_BITMAP instance using the gflAllockBitmap function, then operate a memcpy on the GFL_BITMAP::Data ??

Because, in my program (not in this little test code), the greyscale buffer is computed during by a previous step and is already in memory ....
