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

Scanport uses the command line parameter to pass the range of port numbers to be scanned into the program. The parameter format is minport-maxport. If you only enter one port number, the scanport program only scans this p
