Constructor.

Parameters:

colorModel -

Method Details

applyTransforms

public BufferedImage applyTransforms(BufferedImage imgInput,
 BufferedImage imgOutput)

Description copied from interface: ImageRenderer

Apply the required transforms to a BufferedImage to get the appropriate display. imgOutput should always be an RGB image (of some kind), or null if a new image should be created. imgInput should always be an image of the kind that matches the imgData, e.g. RGB/non-RGB, same number of channels, same bit-depth.

Specified by:

applyTransforms in interface ImageRenderer

Parameters:

imgInput - input image

imgOutput - output image, with the same width and height as the input; if null or the image size is inconsistent, a new RGB image should be created

Returns:

imgOutput, or a new RGB image created for the output

setColorModel

public void setColorModel(ColorModel model)

Set the color model to use.

Parameters:

model -

getColorModel

public ColorModel getColorModel()

Get the ColorModel for this renderer (may be null).

Returns:

getLastChangeTimestamp

public long getLastChangeTimestamp()

Description copied from interface: ImageRenderer

Timestamp of the last change (probably in milliseconds).

This can be used to identify when the status has changed.

Specified by:

getLastChangeTimestamp in interface ImageRenderer

Returns:

getUniqueID

public String getUniqueID()

Description copied from interface: ImageRenderer

Get a unique key, which will be used for caching.

The only requirement is that the key is unique for the ImageRenderer in its current state. It is suggested to base it on the full class name, a counter for instances of this class, and a timestamp derived from the last change.

Specified by:

getUniqueID in interface ImageRenderer

Returns:
