What is this ?

RGA(Renesas Graphics Architecture) sample program using GR-PEACH.
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.
  • The memory area was defined by the application is available as a drawing destination or for input images.
  • Allows drawing of translucent images and translucent drawing using an alpha mask.

Please refer to the following link about RGA.
https://www.renesas.com/en-us/software/D3018075.html
This sample program draws in the frame buffer by using the buffer drawing mode of RGA.
In addition, supporting compiler is ARMCC, GCC ARM and IAR.

About image to be drawn

Image files that are used in the sample program is easily possible replacement by using the "Convert Image to Binary Table" tool below.
This tool generates "BinaryImage_RZ_A1H.c" and "BinaryImage_RZ_A1H.h" in the Images folder and converts each image file to binary. Then, this tool outputs the data to "RGA_Sample_BinaryImage" table of "BinaryImage_RZ_A1H.c" and defines the macro name indicating the offset position in the table to "BinaryImage_RZ_A1H.h".
The sample program executes with reference to this macro name for offset.

概要

GR-PEACHを使ったRGA(ルネサスグラフィックスライブラリ)サンプルプログラムです。
RGAの特徴は以下の通りです。

  • ハードウェア アクセラレーションを使って高速に描画
  • W3C 標準である HTML Canvas 2D Context をベースに作成した API のため、学習が容易。
    また HTML Canvas 2D Context の下位互換として動作できる C++API を提供
  • アプリケーション側で用意したメモリー領域を描画先、または、入力画像として使用可能
  • 半透明な画像の描画と、アルファマスクを使った任意の形状の描画

RGAの詳細については、以下を参照下さい。
https://www.renesas.com/ja-jp/software/D3018074.html
本サンプルプログラムでは、RGAのバッファー描画モードを使ってフレームバッファに描画しています。
なお、対応するコンパイラはARMCC、GCC ARM、IARです。

描画する画像について

サンプルプログラムで使用している画像ファイルは、下記の"Convert Image to Binary Table"ツールを利用する事で、簡単に差し替えが可能です。
このツールは、Imagesフォルダ内にBinaryImage_RZ_A1H.c ファイルと BinaryImage_RZ_A1H.h ファイルを生成し、各画像ファイルをバイナリ変換します。そして、そのデータをBinaryImage_RZ_A1H.c ファイルのRGA_Sample_BinaryImageテーブルに出力し、BinaryImage_RZ_A1H.h ファイルにテーブル内のオフセット位置を示すマクロ名を定義します。
サンプルプログラムでは、オフセット用のマクロ名を参照して動作します。
