Using XOR in graphics programming

A clever wheeze!

とじ込み／提出する: lt4Ne-XorDemo.htm)

This isn't like most of my other pages... and is unlike the pages that say that!

While there's little explanation here about the code this page makes 利用できる to you, there is a lot of "tutorial" stuff to be gleaned from the 解放する／自由な, downloadable sourcecode 論証するing the use of XOR in graphics programming.

In a nutshell, using XOR makes it really simple to make things appear and disappear on the 審査する. This can be used, say, to make it look like a ball is moving across the 審査する... homage to Pong, please!...

You draw the ball at, say, the left 手渡す 辛勝する／優位. Let that stay there a moment. Then "undraw" it, and (very quickly) re-draw it, but just a bit to the 権利 of where it was before. Keep this up, and people will "see" a ball moving across the 審査する.

There's an .exe in the .zip which is 単に what the sourcecode there produces. But you can run it to see what the sourcecode does. (By the way, it will run 直接／まっすぐに from the 単に 見解（をとる）d .zip, but it will moan when you やめる, because it is trying to 令状 to an .ini とじ込み／提出する. No 害（を与える） done, but (of course) what would have gone into the .ini とじ込み／提出する (まず第一に／本来 your wishes regarding the size and position of the window) is lost.

The 使用／適用 gives you a chance to see XOR in 活動／戦闘, and to look at the code 達成するing the 影響s you see.

What are you waiting for? Go download it; have fun!

(The program also uses some other neat tricks 関係のない to the XOR 道具. Not how it manages to create a "追跡する" of squares appearing and disappearing. (Buttons "Button6-急速な／放蕩な" and "Button6-slow".)
