| ToGcBitmap() | Gets the frame image as a GcBitmap.
Many GIF files use frames with transparent pixels where the previous frame is partly visible. If you read multiple GIF frames you can improve the performance dramatically by reading frames into the same GcBitmap and passing index of the previous frame in the additional contentFrameIndex parameter. |
| ToGcBitmap(GcBitmap,Int32) | Reads the frame image into an existing GcBitmap. |
