it works with Processing 2.2.1

@christophertino when you get back from vacation... I hit this today when updating https://github.com/hype/HYPE_Processing/blob/library/examples/basics/basics_014_fading/basics_014_fading.pde NullPointerException on HCanvas
Update:
I can run basics_014_fading if I change line 14 to size(640,640, P2D);
and line 21 to HCanvas(640,640,P2D);
For some reason HCanvas breaks when calling loadPixels(), but only when using the JAVA2D renderer.
@shiffman
import hype.*;
HCanvas canvas;
HRect rect;
void setup() {
size(640,640);
H.init(this).background(#242424);
canvas = new HCanvas().autoClear(false).fade(5);
H.add(canvas);
canvas.add( rect = new HRect(25) ).noStroke().fill(#FF3300);
}
void draw() {
rect.loc( (int)random(width), (int)random(height));
H.drawStage();
}
here's what I tested against after moving loadPixels()
to after beginDraw()
Also related to this may be from: https://github.com/hype/HYPE_Processing/blob/library/src/main/java/hype/HCanvas.java#L262
if(!_renderer.equals(PConstants.JAVA2D))
_graphics.loadPixels();
I think you likely want to load the pixels here for all renderers including JAVA2D
.
Thanks for the help man. I think some of these renderers were explicitly defined for the benefit of Processing.js. Since we're dropping support for that, we can probably lose some of those references.
