Page 1 R01AN2840EJ0212 Rev. 2.12 Graphics Library "RGA" Jan.27, 2018 Introduction This application note describes the Graphics Library RGA (Renesas Graphics Architecture) of SH7268/SH7269. The following lists features of the RGA.  Allows high-speed drawing using the hardware acceleration.  The API created based on the W3C standard HTML Canvas 2D Context achieves easy learning. In addition, the RGA provides C++API that is operable as an interface that is backward compatible with HTML Canvas 2D Context.
