PiscesRenderer class is basic public API accessing Pisces library capabilities. Pisces renderer is intended to draw directly into underlying data buffer of AbstractSurface. Basic implementation of AbstractSurface is e.g. GraphicsSurface. All coordinates are in 15.16 representation. ie. 13 will be passed as 13<<16. Simple use-case for PiscesRenderer together with GraphicsSurface would be e.g. -

GraphicsSurface surface = new GraphicsSurface();

PiscesRenderer pr = new PiscesRenderer(surface);

Now, when we have instances ready, we can render something from our paint(Graphics g) method


void paint(Graphics g) {
surface.bindTarget(g);
//we set stroke color
pr.setColor(0xFF, 0x00, 0xAF);
// we set required Porter-Duff Compositing Rule
pr.setComposite(RendererBase.COMPOSITE_SRC_OVER);

//switch antialising on/off as required
pr.setAntialiasing(true); // on

pr.setTransform(ourTransform6Matrix);

//and now let's draw something finally
pr.beginRendering(RendererBase.WIND_EVEN_ODD);
pr.moveTo(50 << 16, 100 << 16); //
pr.lineTo(30<<16, 1<<16); pr.endRendering();

surface.releaseTarget();
}

Parameters
red:int

a value between 0 and 255.

green:int

a value between 0 and 255.

blue:int

a value between 0 and 255.

alpha:int

a value between 0 and 255.

setColorback to summary
public void setColor(int red, int green, int blue)

Sets the current paint color. An alpha value of 255 is used. Calling setColor also switches painting mode - i.e. if we have specified gradient, or texture previously, this will be overcome with setColor call. Also note, that 3-param setColor sets fully opaque RGB color. To draw with semi-transparent color use 4-param convenience method.

Parameters
red:int

a value between 0 and 255.

a value between 0 and 255.

a value between 0 and 255.
