Constructor Detail

ImageRoi

public ImageRoi(int x,
                int y,
                java.awt.image.BufferedImage bi)

Creates a new ImageRoi from a BufferedImage.

ImageRoi

                ImageProcessor ip)

Creates a new ImageRoi from a ImageProcessor.

Method Detail

draw

public void draw(java.awt.Graphics g)

Overrides:

draw in class Roi

setComposite

public void setComposite(java.awt.Composite composite)

Sets the composite mode.

setOpacity

public void setOpacity(double opacity)

Sets the composite mode using the specified opacity (alpha), in the range 0.0-1.0, where 0.0 is fully transparent and 1.0 is fully opaque.

getSerializedImage
