BufferedImageOp (Java SE 19 & JDK 19)

All Known Implementing Classes:

AffineTransformOp, ColorConvertOp, ConvolveOp, LookupOp, RescaleOp

public interface BufferedImageOp

This interface describes single-input/single-output operations performed on

objects. It is implemented by

,

,

,

, and

. These objects can be passed into a

to operate on a

in the ImageProducer-ImageFilter-ImageConsumer paradigm.

Classes that implement this interface must specify whether or not they allow in-place filtering-- filter operations where the source object is equal to the destination object.

This interface cannot be used to describe more sophisticated operations such as those that take multiple sources. Note that this restriction also means that the values of the destination pixels prior to the operation are not used as input to the filter operation.

• Method Summary

  Creates a zeroed destination image with the correct size and number of bands.

  Performs a single-input/single-output operation on a BufferedImage.

  Returns the bounding box of the filtered destination image.

  Returns the location of the corresponding destination point given a point in the source image.

  Returns the rendering hints for this operation.

• Method Details
  • filter

    Performs a single-input/single-output operation on a

    BufferedImage

    . If the color models for the two images do not match, a color conversion into the destination color model is performed. If the destination image is null, a

    BufferedImage

    with an appropriate

    ColorModel

    is created.

    An IllegalArgumentException may be thrown if the source and/or destination image is incompatible with the types of images $ allowed by the class implementing this filter.

    Parameters:

    src - The BufferedImage to be filtered

    dest - The BufferedImage in which to store the results$

    Returns:

    The filtered BufferedImage.

    Throws:

    IllegalArgumentException - If the source and/or destination image is not compatible with the types of images allowed by the class implementing this filter.

  • getBounds2D

    Returns the bounding box of the filtered destination image. An IllegalArgumentException may be thrown if the source image is incompatible with the types of images allowed by the class implementing this filter.

    Parameters:

    src - The BufferedImage to be filtered

    Returns:

    The Rectangle2D representing the destination image's bounding box.

  • createCompatibleDestImage

    Creates a zeroed destination image with the correct size and number of bands. An IllegalArgumentException may be thrown if the source image is incompatible with the types of images allowed by the class implementing this filter.

    Parameters:

    src - The BufferedImage to be filtered

    destCM - ColorModel of the destination. If null, the ColorModel of the source is used.

    Returns:

    The zeroed destination image.

  • getPoint2D

    Returns the location of the corresponding destination point given a point in the source image. If dstPt is specified, it is used to hold the return value.

    Parameters:

    srcPt - the Point2D that represents the point in the source image

    dstPt - The Point2D in which to store the result

    Returns:

    The Point2D in the destination image that corresponds to the specified point in the source image.

  • getRenderingHints

    Returns the rendering hints for this operation.

    Returns:

    The RenderingHints object for this BufferedImageOp. Returns null if no hints have been set.
