  • Method Details

    • apply

      Mat apply(ImageData<BufferedImage> imageData, RegionRequest request) throws IOException
      Apply the operation to the requested region of the image.

      The data and region are provided, rather than specified pixels, because the operation might require additional information available within the ImageData, and optionally adjust the request (e.g. to incorporate padding to remove boundary artifacts).

      Note for implementers: Any such padding must be removed from the output before it is returned.

      Parameters:
      imageData -
      request -
      Returns:
      Throws:
      IOException

    • supportsImage

      boolean supportsImage(ImageData<BufferedImage> imageData)
      Query whether this transform can be applied to the specified image. Reasons why it may not be include the type or channel number being incompatible.
      Parameters:
      imageData -
      Returns:

    • getChannels

      List<ImageChannel> getChannels(ImageData<BufferedImage> imageData)
      Get appropriate channels to reflect the output of this transform, given the input.
      Parameters:
      imageData -
      Returns:

    • appendOps

      ImageDataOp appendOps(ImageOp... ops)
      Append one or more additional ImageOps sequentially. This ImageDataOp is unchanged, and a new one is created with the additional op appended.
      Parameters:
      ops -
      Returns:

    • getOutputType

      PixelType getOutputType(PixelType inputType)
      Get the output pixel type.
      Parameters:
      inputType - the pixel type of the input image
      Returns:
      the output pixel type
