- renderTarget
 
- an instance of RenderTarget
 - size
 
- The dimension of the bitmap to create in pixels.
 - dataPointer
 
- A pointer to the memory location of the image data, or NULL to create an uninitialized bitmap.
 - pitch
 
- The byte count of each scanline, which is equal to (the image width in pixels * the number of bytes per pixel) + memory padding. If srcData is NULL, this value is ignored. (Note that pitch is also sometimes called stride.)
