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.
|
| Modifier and Type | Method and Description |
|---|---|
void |
setDimensions(int w,
int h)
Override the source image's dimensions and pass the dimensions
of the rectangular cropped region to the ImageConsumer.
|
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.
|
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.
|
void |
setProperties(Hashtable<?,?> props)
Passes along the properties from the source object after adding a
property indicating the cropped 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.
