Method Detail

imageUpdate

void imageUpdate(ImageReader source,
               BufferedImage image,
               int minX,
               int minY,
               int width,
               int height,
               int periodX,
               int periodY,
               int[] bands)

Reports that a given region of the image has been updated.

Parameters:

source - the ImageReader object calling this method

image - the BufferedImage being updated

minX - the X coordinate of the leftmost updated column of pixels

minY - the Y coordinate of the uppermost updated row of pixels

width - the number of updated pixels horizontally

height - the number of updated pixels vertically

periodX - the horizontal spacing between updated pixels; a value of 1 means no gaps

periodY - the vertical spacing between updated pixels; a value of 1 means no gaps

bands - an array of ints indicating which bands are being updated

passComplete

void passComplete(ImageReader source,
                BufferedImage image)

Reports that the current read operation has completed a progressive pass.

Parameters:
