php合成或者创建gif动画

1. 首先需要确认GD库是否正常。

2. 如果是合成图片，请确保把分解的图片放在frames的文件夹里面。

3. GIFEncoder.class.php 类

1. include "GIFEncoder.class.php";
3. ob_start();
4. $board_width = 60;
5. $board_height = 60;
6. $pad_width = 5;
7. $pad_height = 15;
8. $ball_size = 5;
9. $game_width = $board_width - $pad_width*2 - $ball_size;
10. $game_height = $board_height-$ball_size;
12. $x = 0;
13. $y = rand(0,$game_height);
14. $xv = rand(1,10);
15. $yv = rand(1,10);
16. $pt[] = array($x,$y);
17. do{
18. $x += $xv;
19. $y += $yv;
20. if($x > $game_width){
21. $xv = -1*$xv;
22. $x = $game_width - ($x-$game_width);
23. }elseif($x $xv = -1*$xv;
24. $x = abs($x);
25. }
26. if($y>$game_height){
27. $yv = -1*$yv;
28. $y = $game_height - ($y - $game_height);
29. }elseif($y $yv = -1*$yv;
30. $y = abs($y);
31. }
32. $pt[] = array($x,$y);
33. }while($x!=$pt[0][0]||$y!=$pt[0][1]);
35. $i = 0;
36. while(isset($pt[$i])){
37. $image = imagecreate($board_width,$board_height);
38. imagecolorallocate($image, 0,0,0);
39. $color = imagecolorallocate($image, 255,255,255);
40. $color2 = imagecolorallocate($image, 255,0,0);
42. if($pt[$i][1] + $pad_height imagefilledrectangle($image,0,$pt[$i][1],$pad_width, $pt[$i][1]+$pad_height,$color);
43. }else{
44. imagefilledrectangle($image,0,$board_width-$pad_height,$pad_width, $board_width,$color);
45. }
46. imagefilledrectangle($image,$board_width-$pad_width,0,$board_width, $board_height,$color2);
47. imagefilledrectangle($image,$pad_width+$pt[$i][0], $ball_size+$pt[$i][1]-$ball_size, $pad_width+$pt[$i][0]+$ball_size, $ball_size+$pt[$i][1],$color);
48. //imagesetpixel($image,$pt[$i][0],$pt[$i][1],$color);
49. imagegif($image);
50. imagedestroy($image);
51. $imagedata[] = ob_get_contents();
52. ob_clean();
53. ++$i;
54. }
56. $gif = new GIFEncoder(
57. $imagedata,
58. 100,
59. 0,
60. 2,
61. 0, 0, 1,
62. "bin"
63. );
65. Header ('Content-type:image/gif');
66. echo $gif->GetAnimation();
67. ?>
