public class CropImageFilter
extends ImageFilter
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.

FilteredImageSource, ImageFilter

Constructor Index

o CropImageFilter(int, int, int, int)
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.

Method Index

o setDimensions(int, int)
Override the source image's dimensions and pass the dimensions of the rectangular cropped region to the ImageConsumer.
o setPixels(int, int, int, int, ColorModel, byte[], int, int)
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.
o setPixels(int, int, int, int, ColorModel, int[], int, int)
Determine if the delivered int pixels intersect the region to be extracted and pass through only that subset of pixels that appear in the output region.
o setProperties(Hashtable)
Passes along the properties from the source object after adding a property indicating the cropped region.

Constructors

o CropImageFilter 
    method CropImageFilter(x=int, -
                           y=int, -
                           w=int, -
                           h=int) public
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.

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

Methods

o setProperties 
    method setProperties(props=Hashtable)  public
Passes along the properties from the source object after adding a property indicating the cropped region.

Overrides:
setProperties in class ImageFilter
o setDimensions 
    method setDimensions(w=int, -
                         h=int)  public
Override the source image's dimensions and pass the dimensions of the rectangular cropped region to the ImageConsumer.

Overrides:

                     scansize=int)  public
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.

                     off=int, -
                     scansize=int)  public
Determine if the delivered int pixels intersect the region to be extracted and pass through only that subset of pixels that appear in the output region.
