gflLoadBitmapFromMemory() and PNG ColorType 3 with Alpha
Posted: Thu Mar 25, 2010 4:30 pm
i'm using gflLoadBitmapFromMemory() on a PNG file image with ColorType 3 (indexed color) and transparency chunk which stores the Alpha channel for the LUT.
unfortunately the bitmap returned by gflLoadBitmapFromMemory() apparently ignores the Alpha channel from the PNG and returns image data with an Alpha value of 0xFF for all pixels (tested with GFL SDK 2.82 and 3.11) 
we'd really appreciate a fix for this!
Code: Select all
GFL_LOAD_PARAMS load_params;
gflGetDefaultLoadParams( &load_params );
load_params.Flags = GFL_LOAD_ORIGINAL_DEPTH | GFL_LOAD_FORCE_COLOR_MODEL;
load_params.ColorModel = GFL_RGBA;
GFL_BITMAP *p_bitmap = 0;
GFL_ERROR const gfl_error = gflLoadBitmapFromMemory( reinterpret_cast<GFL_UINT8 const *>(pIn), filled, &p_bitmap, &load_params, NULL );
we'd really appreciate a fix for this!
