setPixels
Writes a rectangular area of pixels in the destination
BufferedImage
. Calling this method on an image of type different fromBufferedImage.TYPE_INT_ARGB
andBufferedImage.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
- ispixels
is non-null and of length < w*h
