Class ScaleReplication
java.lang.Object
net.sourceforge.jiu.ops.Operation
net.sourceforge.jiu.ops.ImageToImageOperation
net.sourceforge.jiu.geometry.ScaleReplication
- public class ScaleReplication
- extends ImageToImageOperation
Changes the pixel resolution of an image by replicating (or dropping) pixels.
A fast but low quality scaling algorithm that works with all kinds
of image types.
Resample
provides better quality, but is slower and works with
intensity-based image data types only.
Usage example
The input image will be scaled to an image that is twice as wide as
itself and three times as high.
ScaleReplication scale = new ScaleReplication();
scale.setInputImage(image); // something implementing IntegerImage
scale.setSize(image.getWidth() * 2, image.getHeight() * 2);
scale.process();
PixelImage scaledImage = scale.getOutputImage();

- Description copied from class:
Operation
- This method does the actual work of the operation.
It must be called after all parameters have been given to the operation object.
- Overrides:
process
in class Operation
- Throws:
MissingParameterException
- if any mandatory parameter was not given to the operation
WrongParameterException
- if at least one of the input parameters was
not initialized appropriately (values out of the valid interval, etc.)
setSize
public void setSize(int width,
int height)
- Specify the resolution to be used for the image to be created.
- Parameters:
width
- horizontal resolution of the new imageheight
- vertical resolution of the new image
- Throws:
IllegalArgumentException
- if any of the arguments is smaller than 1
