for the graphic context. You also have all the affinsic deformation capabilities provided by Graphics2D objects. To obtain a single pixel from a BufferedImage object, you can call its getRGB () method and provide the x and y coordinates of the pixel as the int type parameter. This pixel is returned in the int type in the TYPE_INT_ARGB format. it consists of four 8-bit values (representing the alpha value and the RGB color component) and a 32-bit character. GetRGB () also has an overloaded vers
