getRGB
public int[] getRGB(BufferedImage image,
int x,
int y,
int width,
int height,
int[] pixels)
- A convenience method for getting ARGB pixels from an image. This tries to
avoid the performance penalty of BufferedImage.getRGB unmanaging the
image.
- Parameters:
image
- a BufferedImage objectx
- the left edge of the pixel blocky
- the right edge of the pixel blockwidth
- the width of the pixel arryheight
- the height of the pixel arrypixels
- the array to hold the returned pixels. May be null.
- Returns:
- the pixels
- See Also:
setRGB(java.awt.image.BufferedImage, int, int, int, int, int[])
setRGB
public void setRGB(BufferedImage image,
int x,
int y,
int width,
int height,
int[] pixels)
- A convenience method for setting ARGB pixels in an image. This tries to
avoid the performance penalty of BufferedImage.setRGB unmanaging the
image.
- Parameters:
image
- a BufferedImage objectx
- the left edge of the pixel blocky
- the right edge of the pixel blockwidth
- the width of the pixel arryheight
- the height of the pixel arrypixels
- the array of pixels to set- See Also:
