  • Method Summary

    Modifier and Type
    Method
    Description
    boolean
    addSample(int index, float r, float g, float b, float alpha)
    Adds an RGBA sample to one pixel, using separate float scalars.
    boolean
    addSample(int index, int rgba)
    Adds an RGBA sample to one pixel, using an RGBA integer.
    boolean
    addSample(int index, int rgb, float alpha)
    Adds an RGBA sample to one pixel, using an RGB integer and separate float value.
    void
    Clears all samples from this buffer.
    int
    toRgbInt(int index)
    Returns the result of compositing all the added samples as a non-premultiplied ARGB integer.
  • Method Details

    • clear

      void clear()
      Clears all samples from this buffer.
    • addSample

      boolean addSample(int index, float r, float g, float b, float alpha)
      Adds an RGBA sample to one pixel, using separate float scalars.
      Parameters:
      index - pixel index
      r - red value, 0-1
      g - green value, 0-1
      b - blue value, 0-1
      alpha - alpha value, 0-1
      Returns:
      true if saturation has been reached, that is further samples added to this pixel will have no effect
    • addSample

      boolean addSample(int index, int rgb, float alpha)
      Adds an RGBA sample to one pixel, using an RGB integer and separate float value.
      Parameters:
      index - pixel index
      rgb - integer containing RGB in lower 24 bits; highest byte is ignored
      alpha - alpha value, 0-1
      Returns:
      true if saturation has been reached, that is further samples added to this pixel will have no effect
    • addSample

      boolean addSample(int index, int rgba)
      Adds an RGBA sample to one pixel, using an RGBA integer.
      Parameters:
      index - pixel index
      rgba - integer containing RGBA values one per byte
      Returns:
      true if saturation has been reached, that is further samples added to this pixel will have no effect
    • toRgbInt

      int toRgbInt(int index)
      Returns the result of compositing all the added samples as a non-premultiplied ARGB integer. This is suitable for use with BufferedImage setRGB methods) or, more efficiently, an RgbImage buffer.
      Parameters:
      index - pixel index
      Returns:
      ARGB integer
