getPixels
protected int[] getPixels(BufferedImage img,

int h,
int[] pixels)
- Returns an array of integer pixels in the default RGB color model
(TYPE_INT_ARGB) and default sRGB color space, from a portion of the image
data.
- Parameters:
img
- Image.x
- The starting X coordinatey
- The starting Y coordinatew
- Width of region.h
- Height of region.pixels
- If not null
, the pixels are written here.
- Returns:
- Array or RGB pixels.
setPixels
protected void setPixels(BufferedImage img,
int x,
int y,
int w,
int h,
int[] pixels)
Writes a rectangular area of pixels in the destination
BufferedImage
. Calling this method on an image of type
different from BufferedImage.TYPE_INT_ARGB
and
BufferedImage.TYPE_INT_RGB
will unmanage the image.
- Parameters:
img
- the destination imagex
- the x location at which to start storing pixelsy
- the y location at which to start storing pixelsw
- the width of the rectangle of pixels to storeh
- the height of the rectangle of pixels to storepixels
- an array of pixels, stored as integers
- Throws:
IllegalArgumentException
- is pixels
is non-null and of length < w*h
