RE: [RZ/A1H][VDC5] Reducing the size of graphic frame

Hi all,

Thanks for your support.

By using the Chroma-key processing (VDC5) on graphic 2, currently, the size of graphic frame is decreased from 1500 KB (800x480x4) to 1152 KB (800x480x3) and graphic 0 and graphic 2 can blend in together.

However, if possible, I want to reduce more and more buffer frame ^^. So, I’m very grateful if anyone has any ideal in this case.

Below is some ideals of mine:

  + Using CLUT (color lookup table) to change frame format from 32bits (aRBG8888) to 8 bits (gray scale) or 16 bits (YCrCb, RGB565, …)

  + Using the rect alpha blend (thank for proposal of Tera-san), I’m testing with this case.

Thank you!
