-
x-coordinate of top-left corner of piece to crop.
- y
-
y-coordinate of top-left corner of piece to crop.
- width
-
Width of image to crop.
- height
-
Height of image to crop.

Instance Methods
setDimensions
public void setDimensions (int width, int height)
- Parameters
-
- width
-
Ignored parameter.
- height
-
Ignored parameter.
- width
- Overrides
-
ImageFilter.setDimensions(int, int)
- Description
-
Called with the original image's dimensions; these dimensions are ignored. The method in turn calls the ImageConsumer with the dimensions of the cropped image.
setPixels
public void setPixels (int x, int y, int width, int height, ColorModel model, byte[] pixels, int offset, int scansize)
- Parameters
-
- x
-
x-coordinate of top-left corner of pixel data delivered with this method call.
- y
-
y-coordinate of top-left corner of pixel data delivered with this method call.
- width
-
Width of the rectangle of pixel data delivered with this method call.
- height
-
Height of the rectangle of pixel data delivered with this method call.
- model
-
Color model of image data.
- pixels
-
Image data.
- offset
-
Offset from beginning of the pixels array.
- scansize
-
Size of each line of data in pixels array.
- x
- Overrides
-
ImageFilter.setPixels(int, int, int, int, ColorModel, byte[], int, int)
- Description
-
Receives a rectangle of image data from the ImageProducer; crops these pixels and delivers them to any ImageConsumers.
public void setPixels (int x, int y, int width, int height, ColorModel model, int[] pixels, int offset, int scansize)
- Parameters
-
- x
-
x-coordinate of top-left corner of pixel data delivered with this method call.
- y
-
y-coordinate of top-left corner of pixel data delivered with this method call.
- width
-
Width of the rectangle of pixel data delivered with this method call.
- height
-
Height of the rectangle of pixel data delivered with this method call.
- model
-
Color model of image data.
- pixels
-
Image data.
- offset
-
Offset from beginning of the pixels array.
- scansize
-
Size of each line of data in pixels array.
- x
- Overrides
-
ImageFilter.setPixels(int, int, int, int, ColorModel, int[], int, int)
- Description
-
Receives a rectangle of image data from the ImageProducer; crops these pixels and delivers them to any ImageConsumers.
setProperties
public void setProperties (Hashtable properties)
- Parameters
