Method Detail

setChannelRectangle

public void setChannelRectangle(int channel,
                                int x,
                                int y,
                                int width,
                                int height,
                                byte[] pixels,
                                int offset,
                                int scansize)
                         throws ImageAccessException

Set a rectangular area of pixel data for a single byte channel of the image. Channels use the standard AARRGGBB mask, where ALPHA/RED/GREEN/BLUE represent the position of the data though the actual ARGB interpretation if handled by the ColorModel. The channel of data thus may not represent the color component suggested by the channel label.

Parameters:

channel - the channel to set, either CHANNEL_ALPHA, CHANNEL_RED, CHANNEL_GREEN, or CHANNEL_BLUE

x - x-coordinate

y - y-coordinate

width - rectangle width

height - rectangle height

pixels - pixel data

offset - offset in pixels to start reading from

scansize - length from the start of one row to the start of the next in pixels

Throws:

ImageAccessException - if an error prevents image from being accessed

setChannelRow

public void setChannelRow(int channel,
                          int y,
                          byte[] pixels,
                          int offset)
                   throws ImageAccessException

setChannelPixel

public void setChannelPixel(int channel,
                            int x,
                            int y,
                            byte value)
                     throws ImageAccessException

Set a channel of data for a pixel.

Parameters:

channel - the channel to set, either CHANNEL_ALPHA, CHANNEL_RED, CHANNEL_GREEN, or CHANNEL_BLUE

x - x-coordinate

y - y-coordinate

value - channel value

Throws:

ImageAccessException - if an error prevents image from being accessed
