Using Arduino_GFX and sprites or canvas.

[JeffreyRon]

Im just getting up to speed with Arduino_GFX and I want to do sprites. Or perhaps canvas. I'm having trouble understanding what to use with Arduino_GFX. I know more about TFT_eSPI and sprites. Anybody got some hello world type sprites type functionality for Arduino_GFX.

it have a built-in example call spritegif

Thanks for your response. Unfortunately that example is way over my head with the indexing etc. I need to start simple. I've been trying various things and can't seem to get the actual displaying of the canvas syntax correct. The TFT_eSPI sprites are so simple. Maybe I'm just missing something simple here?

What I've tried...

(this compiles..........)

Arduino_RGB_Display gfx = new Arduino_RGB_Display(800 / width /, 480 / height /, rgbpanel, 0 / rotation /, true / auto_flush */);
Arduino_GFX canvasGfx = new Arduino_Canvas(800 / width /, 480 / height */, gfx); // 16bit

gfx->begin();
canvasGfx->begin();

gfx->setTextColor(WHITE);
gfx->drawRect(0, 0, 800, 480, ORANGE);
gfx->println("Hello World!1");

canvasGfx->setTextColor(RED, BLUE);
canvasGfx->fillScreen(BLACK);
canvasGfx->drawCircle(400, 240, 60, RED);
canvasGfx->println("Hello World2");

But then when it's time to actually display the canvas, I've tried all of these and many more and none compile....

//gfx->draw(canvasGfx);
gfx->drawRGBBitmap(0, 0, canvasGfx->getBuffer(), 800, 480)
//gfx->draw3bitRGBBitmap(0, 0, canvasGfx->getBuffer(), 800, 480) //when using the 3bit initialization
//gfx->draw3bitRGBBitmap(0, 0, canvasGfx.getBuffer(), 800, 480) //when using the 3bit initialization
//gfx->drawBitmap(0, 0, canvasGfx, 800, 480)

if you want to use Arduino_GFX with sprite, spritegif example is the beginning. You may not know how it works, but simply try to run the example first.
