| These pages use a bitwise operator to produce gradients. It comes from C language, based on binary numbers, and works only in true color images (png or jpeg). For more information on bitwise operators and php see the manual at PHP.net. |
| The above gradients were created with the following PHP script. The script comes from Rasmus Lerdorf, the creator of PHP, and can be seen on his site. PDF file |
| The gradients can be mirrored for a round gradient effect. |
| The Code for the above gradients is as follows. |
| By changing the last number in the bitwise operator $x<<1, etc you will get a different line image. These can be seen with the bitwise number on this page. |
| You can also get some interesting effects by using ellipses and arcs. You can create backgrounds for your art work. You can also create masks. |
