Edit pixel values

Question

How to edit pixel values of an image in Java. Is there any method to change pixel values?

Answer 1

In BufferedImage: public void setRGB(int x, int y, int rgb)

Sets a pixel in this BufferedImage to the specified RGB value. The pixel is assumed to be in the default RGB color model, TYPE_INT_ARGB, and default sRGB color space. For images with an IndexColorModel, the index with the nearest color is chosen.

Answer 2

For example:

BufferedImage image = ...
image.setRGB(x, y, 0);

From documentation:

 void setRGB(int x, int y, int rgb)
 //Sets a pixel in this BufferedImage to the specified RGB value.
