jdk.awt.image.BufferedImageFilter — clojure-interop/java.awt 1.0.5

The BufferedImageFilter class subclasses an ImageFilter to provide a simple means of using a single-source/single-destination image operator (BufferedImageOp) to filter a BufferedImage in the Image Producer/Consumer/Observer paradigm. Examples of these image operators are: ConvolveOp, AffineTransformOp and LookupOp.

->buffered-image-filter clj

(->buffered-image-filter op)

Constructor.

Constructs a BufferedImageFilter with the specified single-source/single-destination operator.

op - the specified BufferedImageOp to use to filter a BufferedImage - java.awt.image.BufferedImageOp

throws: java.lang.NullPointerException - if op is null

get-buffered-image-op clj

(get-buffered-image-op this)

Returns the BufferedImageOp.

returns: the operator of this BufferedImageFilter. - java.awt.image.BufferedImageOp

image-complete clj

(image-complete this status)

Filters the information provided in the imageComplete method of the ImageConsumer interface.

Note: This method is intended to be called by the ImageProducer of the Image whose pixels are being filtered. Developers using this class to retrieve pixels from an image should avoid calling this method directly since that operation could result in problems with retrieving the requested pixels.

status - the status of image loading - int

throws: java.awt.image.ImagingOpException - if there was a problem calling the filter method of the BufferedImageOp associated with this instance.

set-color-model clj

(set-color-model this model)

Filters the information provided in the setColorModel method of the ImageConsumer interface.

If model is null, this method clears the current ColorModel of this BufferedImageFilter.

Note: This method is intended to be called by the ImageProducer of the Image whose pixels are being filtered. Developers using this class to retrieve pixels from an image should avoid calling this method directly since that operation could result in problems with retrieving the requested pixels.

model - the ColorModel to which to set the ColorModel of this BufferedImageFilter - java.awt.image.ColorModel

set-dimensions clj

(set-dimensions this width height)

Filters the information provided in the setDimensions method of the ImageConsumer interface.

Note: This method is intended to be called by the ImageProducer of the Image whose pixels are being filtered. Developers using this class to retrieve pixels from an image should avoid calling this method directly since that operation could result in problems with retrieving the requested pixels.

width - the width to which to set the width of this BufferedImageFilter - int height - the height to which to set the height of this BufferedImageFilter - int

set-pixels clj

(set-pixels this x y w h model pixels off scansize)

Filters the information provided in the setPixels method of the ImageConsumer interface which takes an array of bytes.

Note: This method is intended to be called by the ImageProducer of the Image whose pixels are being filtered. Developers using this class to retrieve pixels from an image should avoid calling this method directly since that operation could result in problems with retrieving the requested pixels.

x - the X coordinate of the upper-left corner of the area of pixels to be set - int y - the Y coordinate of the upper-left corner of the area of pixels to be set - int w - the width of the area of pixels - int h - the height of the area of pixels - int model - the specified ColorModel - java.awt.image.ColorModel pixels - the array of pixels - byte[] off - the offset into the pixels array - int scansize - the distance from one row of pixels to the next in the pixels array - int

throws: java.lang.IllegalArgumentException - if width or height are less than zero.
