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include "GIFEncoder.class.php";ob_start();$board_width = 60;$board_height = 60;$pad_width = 5;$pad_height = 15;$ball_size = 5;$game_width = $board_width - $pad_width*2 - $ball_size;$game_height = $board_height-$ball_size;$x = 0;$y = rand(0,$game_height);$xv = rand(1,10);$yv = rand(1,10);$pt[] = array($x,$y);do{$x += $xv;$y += $yv;if($x > $game_width){$xv = -1*$xv;$x = $game_width - ($x-$game_width);}elseif($x $xv = -1*$xv;$x = abs($x);}if($y>$game_height){$yv = -1*$yv;$y = $game_height - ($y - $game_height);}elseif($y $yv = -1*$yv;$y = abs($y);}$pt[] = array($x,$y);}while($x!=$pt[0][0]||$y!=$pt[0][1]);$i = 0;while(isset($pt[$i])){$image = imagecreate($board_width,$board_height);imagecolorallocate($image, 0,0,0);$color = imagecolorallocate($image, 255,255,255);$color2 = imagecolorallocate($image, 255,0,0);if($pt[$i][1] + $pad_height imagefilledrectangle($image,0,$pt[$i][1],$pad_width, $pt[$i][1]+$pad_height,$color);}else{imagefilledrectangle($image,0,$board_width-$pad_height,$pad_width, $board_width,$color);}imagefilledrectangle($image,$board_width-$pad_width,0,$board_width, $board_height,$color2);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);//imagesetpixel($image,$pt[$i][0],$pt[$i][1],$color);imagegif($image);imagedestroy($image);$imagedata[] = ob_get_contents();ob_clean();++$i;}$gif = new GIFEncoder($imagedata,100,0,2,0, 0, 1,"bin");Header ('Content-type:image/gif');echo $gif->GetAnimation();?>复制代码
