java.awt.image.CropImageFilter
| CropImageFilter | | public class CropImageFilter extends ImageFilter (Code) | | 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.

| Constructor Summary | |
| public | CropImageFilter(int x, int y, int w, int h)
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 Summary | |
| public void | setDimensions(int w, int 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. | | public void | setPixels(int x, int y, int w, int h, ColorModel model, byte pixels, int off, int 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. | | public void | setPixels(int x, int y, int w, int h, ColorModel model, int pixels, int off, int scansize)
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.
Note: This method is intended to be called by the
ImageProducer of the Image whose
pixels are being filtered. | | public void | setProperties(Hashtable 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. |
| CropImageFilter | | public CropImageFilter(int x, int y, int w, int h)(Code) | | 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
Parameters:
y - the y location of the top of the rectangle to be extracted
Parameters:
w - the width of the rectangle to be extracted
Parameters:
h - the height of the rectangle to be extracted |
| setDimensions | | public void setDimensions(int w, int h)(Code) | | 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.
