Method Detail

create
public static RenderedOp create(RenderedImage source0, LookupTableJAI colorMap, KernelJAI errorKernel, RenderingHints hints)(Code)
	Performs error diffusion color quantization using a specified color map and error filter. Creates a `ParameterBlockJAI` from all supplied arguments except `hints` and invokes JAI.create(StringParameterBlockRenderingHints) . See Also: JAI See Also: ParameterBlockJAI See Also: RenderedOp Parameters: source0 - `RenderedImage` source 0. Parameters: colorMap - The color map. Parameters: errorKernel - The error filter kernel.May be `null`. Parameters: hints - The `RenderingHints` to use.May be `null`. The `RenderedOp` destination. throws: IllegalArgumentException - if `source0` is `null`. throws: IllegalArgumentException - if `colorMap` is `null`.
