14. Once the image loading is complete, the task dispatches a
clBitmap::Load2DImage()
call to the main thread, so that the OpenGL texture
can be updated:
class clImageLoadTask: public iTask
{
public:
…
virtual void Run()
{
clPtr<ImageLoadTask> Guard( this );
clPtr<iIStream> In = (FSourceStream == NULL) ?
g_FS->ReaderFromBlob( FSource ) : FSourceStream;
FResult = new clBitmap();
FResult->Load2DImage(In, true);
if ( FCallback )
{
FCallback->FTaskID = GetTaskID();
FCallback->FResult = FResult;
FCallback->FTask = this;
FCallbackQueue->EnqueueCapsule( FCallback );
FCallback = NULL;
}
}
…
};

5_Puzzle
project.
How it works…
The downloading is performed in the global
g_Downloader
object, and the actual decoding
of the downloaded data is done using the
FreeImage
library.
