Accessing the pixels of an image [closed]

Question

Could someone show me here how to access all the pixels of an image in order to be able to build a histogram of that image ?

Answer 1

You can use

java.awt.image.BufferedImage image = ImageIO.read( "image.gif" );
int[] samples = image.getData().getPixel( x, y, null );

// or the pixel converted to the default RGB color model:
int rgb = image.getRGB( x, y )

I think the samples you get from there are the RGB values, but you have to check that...
