    • imageBegin

      public void imageBegin(int w, int h, int bucketSize)
      Description copied from interface: Display
      This is called before an image is rendered to indicate how large the rendered image will be. This allows the display driver to write out image headers or allocate surfaces. Bucket size will be 0 when called from a non-bucket based source.
      Specified by:
      imageBegin in interface Display
      Parameters:
      w - width of the rendered image in pixels
      h - height of the rendered image in pixels
      bucketSize - size of the buckets in pixels
    • imagePrepare

      public void imagePrepare(int x, int y, int w, int h, int id)
      Description copied from interface: Display
      Prepare the specified area to be rendered. This may be used to highlight the work in progress area or simply to setup the display driver to receive the specified portion of the image
      Specified by:
      imagePrepare in interface Display
      Parameters:
      x - x coordinate of the bucket within the image
      y - y coordinate of the bucket within the image
      w - width of the bucket in pixels
      h - height of the bucket in pixels
      id - unique identifier corresponding to the thread which invoked this call
    • imageUpdate

      public void imageUpdate(int x, int y, int w, int h, Color[] data, float[] alpha)
      Description copied from interface: Display
      Update the current image with a bucket of data. The region is guarenteed to be within the bounds created by the call to imageBegin. No clipping is necessary. Colors are passed in unprocessed. It is up the display driver to do any type of quantization, gamma compensation or tone-mapping needed. The array of colors will be exactly w * h long and in row major order.
      Specified by:
      imageUpdate in interface Display
      Parameters:
      x - x coordinate of the bucket within the image
      y - y coordinate of the bucket within the image
      w - width of the bucket in pixels
      h - height of the bucket in pixels
      data - bucket data, this array will be exactly w * h long
      alpha - pixel coverage data, this array will be exactly w * h long
    • imageFill

      public void imageFill(int x, int y, int w, int h, Color c, float alpha)
      Description copied from interface: Display
      Update the current image with a region of flat color. This is used by progressive rendering to render progressively smaller regions of the screen which will overlap. The region is guarenteed to be within the bounds created by the call to imageBegin. No clipping is necessary. Colors are passed in unprocessed. It is up the display driver to do any type of quantization , gamma compensation or tone-mapping needed.
      Specified by:
      imageFill in interface Display
      Parameters:
      x - x coordinate of the region within the image
      y - y coordinate of the region within the image
      w - with of the region in pixels
      h - height of the region in pixels
      c - color to fill the region with
      alpha - pixel coverage
    • imageEnd

      public void imageEnd()
      Description copied from interface: Display
      This call is made after the image has been rendered. This allows the display driver to close any open files, write the image to disk or flush any other type of buffers.
      Specified by:
      imageEnd in interface Display
    • paint

      public void paint(Graphics g)
