Thanks Max, But the problem I'm facing in Imageloader.cpp is the unavailability of raw image data [unsigned char*]. I'm trying to get the image data in ImageLoader::notifyFinished(CachedResource* resource) So that after getting data I can do my changes and set the data again But m_image is not providing me the data. Is there any way I can get the raw data of the image.
