The cropped image filter is an image filter for cropping images. This class extends the
basic ImageFilter class (II-§2.5) to extract a given rectangular region of an existing image
and provides a source for new image containing only the extracted region.
This class is meant to be used in conjunction with a FilteredImageSource (II-§2.4) to produce cropped versions of existing images.
public CropImageFilter(int x, int y, int w, int h)
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
public void setDimensions(int w, int h)
width
- the width of the image
height
- the height of the image
public void
setPixels(int x, int y, int w, int h, ColorModel model, byte pixels[], int off,
int scansize)
