Interface defining a color transform that can extract a float values from a BufferedImage.

The simplest example of this is to extract a single channel (band) from an image.

Method Summary

Modifier and Type	Method	Description
float[]	extractChannel(ImageServer<BufferedImage> server, BufferedImage img, float[] pixels)	Extract a (row-wise) array containing the pixels extracted from a BufferedImage.
String	getName()	Get a displayable name for the transform.
boolean	supportsImage(ImageServer<BufferedImage> server)	Query whether this transform can be applied to the specified image.

Method Details

extractChannel

float[] extractChannel(ImageServer<BufferedImage> server,
 BufferedImage img,
 float[] pixels)

Extract a (row-wise) array containing the pixels extracted from a BufferedImage.

Parameters:

server - the server from which the image was read; can be necessary for some transforms (e.g. to request color deconvolution stains)

img - the image

pixels - optional preallocated array; will be used if it is long enough to hold the transformed pixels

Returns:

supportsImage

boolean supportsImage(ImageServer<BufferedImage> server)

Query whether this transform can be applied to the specified image. Reasons why it may not be include the type or channel number being incompatible.

Parameters:

server -

Returns:

getName

String getName()

Get a displayable name for the transform.

Returns:
