Question: Most of the content on the web is repetitive and simple to describe. Note: content: Create a picture of a word, and the background color of the picture and the color of the word on the picture is required.Solution: First Use the Graphics method SetColor set the color, and then use the class FillRect fill the background color, and then use the class SetColor set a color, and then the class of drawstring stooped. Imageio.write output picture.

We usually use the drawing tools for simple graphics, today we use Java to print some simple graphics The implementation code is as follows Package test; /** * * * @author Hanzel * @ Print Graphics */public class Array {public static void main (string[] args) {//Print Rectangle Int[] A = new int[10];

tag variable, and when the value of the variable is 0 o'clock, the graphic is restored to its original position; The Rotatevalue is the Radian value corresponding to the desired rotation angle.The Heart of SecretsHeart Comprehension 018: angle is converted to radians.Since the rotate () method of the Graphics2D class rotates the shape, it is rotated in radians, so when the given rotation value is an angle, it needs to be converted to radians. In Java

FPS: The abbreviation for frame/sec (frames per second), also known as the frame rate. Refers to the number of frames that are refreshed in 1 seconds, and can be understood as a graphics processor can refresh several times per second. If specific to mobile phone is the ability to play (or record) the number of frames per second. At the same time, the higher the frame rate can be more fluent, more realistic animation. The more frames per second (fps),

Java calls a local image processing library during graph processing. When using Java for graphic processing (for example, image scaling, ima
