createContext	back to summary
public PathGradientPaint.PathGradientContext createContext(ColorModel cm, Rectangle deviceBounds, Rectangle2D userBounds, AffineTransform transform, RenderingHints hints) Implements java.awt.Paint.createContext. Doc from java.awt.Paint.createContext. Creates and returns a `PaintContext` used to generate the color pattern. The arguments to this method convey additional information about the rendering operation that may be used or ignored on various implementations of the `Paint` interface. A caller must pass non-`null` values for all of the arguments except for the `ColorModel` argument which may be `null` to indicate that no specific `ColorModel` type is preferred. Implementations of the `Paint` interface are allowed to use or ignore any of the arguments as makes sense for their function, and are not constrained to use the specified `ColorModel` for the returned `PaintContext`, even if it is not `null`. Implementations are allowed to throw `NullPointerException` for any `null` argument other than the `ColorModel` argument, but are not required to do so. Parameters cm:ColorModel the preferred `ColorModel` which represents the most convenient format for the caller to receive the pixel data, or `null` if there is no preference. deviceBounds:Rectangle the device space bounding box of the graphics primitive being rendered. Implementations of the `Paint` interface are allowed to throw `NullPointerException` for a `null deviceBounds`. userBounds:Rectangle2D the user space bounding box of the graphics primitive being rendered.
