public void maskInterpolatePixels(RTTexture imgtex, RTTexture masktex, int dx, int dy, int dw, int dh, int ix, int iy, int mx, int my)

Implements com.sun.prism.MaskTextureGraphics.maskInterpolatePixels.

Doc from com.sun.prism.MaskTextureGraphics.maskInterpolatePixels.

Use a mask to determine which pixels of an image are to be rendered onto the destination in device space. All coordinates specify pixel coordinates and are integers to reinforce the fact that these are pixel operations, not coordinate rendering operations.

The mask texture controls the contribution of source and destination pixels in the resulting output. Note that a simple multiply of the source texture by the mask texture may not produce the correct masking operation for the case where a non-SrcOver blending mode is in use. In those conditions, it is more accurate to first compute the result of blending the source into the destination and to then use this method to choose how much of the result should be taken from the results of the blending and how much should remain the original destination pixel value. Mathematically, the mask alpha controls a linear interpolation between the image and destination pixels.

    dst.argb = (mask.a * img.argb) + ((1 - mask.a) * dst.argb)

Note that the current composite mode is ignored during this operation.

Parameters

imgtex:RTTexture: the texture containing the source image pixels
masktex:RTTexture: the texture containing the mask pixels, only the alpha channel is used from this texture
dx:int: the X coordinate of the UL destination pixel
dy:int: the Y coordinate of the UL destination pixel
dw:int: the width of the pixel regions to be combined
dh:int: the height of the pixel regions to be combined
ix:int: the X coordinate of the UL pixel in the image texture
iy:int: the Y coordinate of the UL pixel in the image texture
mx:int: the X coordinate of the UL pixel in the mask texture

back to summary

public void setNodeBounds(RectBounds bounds)

Implements com.sun.prism.Graphics.setNodeBounds.

Doc from com.sun.prism.Graphics.setNodeBounds.

Set the node bounds for any node that would like to render objects of a different size to self. This is useful for proportional paints, where by definition proportional paint should be stretched across node bounds to which it has been applied. In most cases nodes/shapes are rendered in a single draw call, and if needed bounds can be determined by inspecting object to be drawn. However not all nodes are so simple, NGText for example can have hundreds of Graphics.drawString(...), draw(...), and fill(...) calls per a single NGText.renderContent(). Use: Before making several draw calls from a single node, setNodeBounds(bounds), when complete invalidate nodeBounds by setNodeBounds(null).

Parameters
