The synthesis here is to combine multiple pictures into one, not into a GIF picture. Friends who need it can download it directly.
Image synthesis can be displayed on the browser and saved to the folder
The example is as follows:
<?php /** * 图片合并 **/ $pic_list = array( 'img2.png', 'img2.png', 'logo.png', 'logo.png', 'logo.png', 'img2.png', 'img2.png', 'img2.png', 'img2.png' ); $pic_list = array_slice($pic_list, 0, 9); // 只操作前9个图片 $bg_w = 150; // 背景图片宽度 $bg_h = 150; // 背景图片高度 $background = imagecreatetruecolor($bg_w,$bg_h); // 背景图片 $color = imagecolorallocate($background, 202, 201, 201); // 为真彩色画布创建白色背景,再设置为透明 imagefill($background, 0, 0, $color); imageColorTransparent($background, $color); $pic_count = count($pic_list); $lineArr = array(); // 需要换行的位置 $space_x = 3; $space_y = 3; $line_x = 0; switch($pic_count) { case 1: // 正中间 $start_x = intval($bg_w/4); // 开始位置X $start_y = intval($bg_h/4); // 开始位置Y $pic_w = intval($bg_w/2); // 宽度 $pic_h = intval($bg_h/2); // 高度 break; case 2: // 中间位置并排 $start_x = 2; $start_y = intval($bg_h/4) + 3; $pic_w = intval($bg_w/2) - 5; $pic_h = intval($bg_h/2) - 5; $space_x = 5; break; case 3: $start_x = 40; // 开始位置X $start_y = 5; // 开始位置Y $pic_w = intval($bg_w/2) - 5; // 宽度 $pic_h = intval($bg_h/2) - 5; // 高度 $lineArr = array(2); $line_x = 4; break; case 4: $start_x = 4; // 开始位置X $start_y = 5; // 开始位置Y $pic_w = intval($bg_w/2) - 5; // 宽度 $pic_h = intval($bg_h/2) - 5; // 高度 $lineArr = array(3); $line_x = 4; break; case 5: $start_x = 30; // 开始位置X $start_y = 30; // 开始位置Y $pic_w = intval($bg_w/3) - 5; // 宽度 $pic_h = intval($bg_h/3) - 5; // 高度 $lineArr = array(3); $line_x = 5; break; case 6: $start_x = 5; // 开始位置X $start_y = 30; // 开始位置Y $pic_w = intval($bg_w/3) - 5; // 宽度 $pic_h = intval($bg_h/3) - 5; // 高度 $lineArr = array(4); $line_x = 5; break; case 7: $start_x = 53; // 开始位置X $start_y = 5; // 开始位置Y $pic_w = intval($bg_w/3) - 5; // 宽度 $pic_h = intval($bg_h/3) - 5; // 高度 $lineArr = array(2,5); $line_x = 5; break; case 8: $start_x = 30; // 开始位置X $start_y = 5; // 开始位置Y $pic_w = intval($bg_w/3) - 5; // 宽度 $pic_h = intval($bg_h/3) - 5; // 高度 $lineArr = array(3,6); $line_x = 5; break; case 9: $start_x = 5; // 开始位置X $start_y = 5; // 开始位置Y $pic_w = intval($bg_w/3) - 5; // 宽度 $pic_h = intval($bg_h/3) - 5; // 高度 $lineArr = array(4,7); $line_x = 5; break; } foreach( $pic_list as $k=>$pic_path ) { $kk = $k + 1; if ( in_array($kk, $lineArr) ) { $start_x = $line_x; $start_y = $start_y + $pic_h + $space_y; } $pathInfo = pathinfo($pic_path); switch( strtolower($pathInfo['extension']) ) { case 'jpg': case 'jpeg': $imagecreatefromjpeg = 'imagecreatefromjpeg'; break; case 'png': $imagecreatefromjpeg = 'imagecreatefrompng'; break; case 'gif': default: $imagecreatefromjpeg = 'imagecreatefromstring'; $pic_path = file_get_contents($pic_path); break; } $resource = $imagecreatefromjpeg($pic_path); // $start_x,$start_y copy图片在背景中的位置 // 0,0 被copy图片的位置 // $pic_w,$pic_h copy后的高度和宽度 imagecopyresized($background,$resource,$start_x,$start_y,0,0,$pic_w,$pic_h,imagesx($resource),imagesy($resource)); // 最后两个参数为原始图片宽度和高度,倒数两个参数为copy时的图片宽度和高度 $start_x = $start_x + $pic_w + $space_x; } header("Content-type: image/jpg"); imagejpeg($background); imagegif($background, "./hero_gam.png"); ?>
