partial bitmap copy in Touchgfx

[amb]

Hello everyone:

I came to a need,that I need to copy part of a dynamic Bitmap to another postion of the same bitmap.I current use a for loop and memcpy func,It works but cost 4ms each run.How can I use touchgfx's blockCopy functions to do this? as DMA2D was already enabled.

I found blitCopy() func in HAL.hpp,but it seems it only use to FRAMEBUFFER.
