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

An ImageFilter class for cropping images. This class extends the basic ImageFilter Class to extract a given rectangular region of an existing Image and provide a source for a new image containing just the extracted region. It is meant to be used in conjunction with a FilteredImageSource object to produce cropped versions of existing images.

->crop-image-filter clj

(->crop-image-filter x y w h)

Constructor.

Constructs a CropImageFilter that extracts the absolute rectangular region of pixels from its source Image as specified by the x, y, w, and h parameters.

x - the x location of the top of the rectangle to be extracted - int y - the y location of the top of the rectangle to be extracted - int w - the width of the rectangle to be extracted - int h - the height of the rectangle to be extracted - int

set-dimensions clj

(set-dimensions this w h)

Override the source image's dimensions and pass the dimensions of the rectangular cropped region to the ImageConsumer.

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

w - the width of the source image - int h - the height of the source image - int

set-pixels clj

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

Determine whether the delivered byte pixels intersect the region to be extracted and passes through only that subset of pixels that appear in the output region.

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

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

set-properties clj

(set-properties this props)

Passes along the properties from the source object after adding a property indicating the cropped region. This method invokes super.setProperties, which might result in additional properties being added.

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

props - the properties from the source object - java.util.Hashtable
