An ImageFilter class for scaling images using the simplest algorithm.
This class extends the basic ImageFilter Class to scale an existing
image and provide a source for a new image containing the resampled
image. The pixels in the source image are sampled to produce pixels
for an image of the specified size by replicating rows and columns of
pixels to scale up or omitting rows and columns of pixels to scale
down.
It is meant to be used in conjunction with a FilteredImageSource
object to produce scaled versions of existing images.
ReplicateScaleFilter(int width,
int height)
Constructs a ReplicateScaleFilter that scales the pixels from
its source Image as specified by the width and height parameters.
Method Summary
void
setDimensions(int w,
int h)
Override the dimensions of the source image and pass the dimensions
of the new scaled size to the ImageConsumer.
void
setPixels(int x,
int y,
int w,
int h,
ColorModel model,
byte[] pixels,
int off,
int scansize)
Choose which rows and columns of the delivered byte pixels are
needed for the destination scaled image and pass through just
those rows and columns that are needed, replicated as necessary.
void
setPixels(int x,
int y,
int w,
int h,
ColorModel model,
int[] pixels,
int off,
int scansize)
Choose which rows and columns of the delivered int pixels are
needed for the destination scaled image and pass through just
those rows and columns that are needed, replicated as necessary.
void
setProperties(Hashtable props)
Passes along the properties from the source object after adding a
property indicating the scale applied.
