Dede缩略图不变形的解决办法

打开/includes/image.func.php文件，//缩图片自动生成函数，来源支持bmp、gif、jpg、png//但生成的小图只用jpg或png格式找到代码第44行function ImageResize至//获得GD的版本之间的代码 用如下的代码覆盖即可

function ImageResize($srcFile,$toW,$toH,$toFile="")

{global $cfg_photo_type;if($toFile==""){ $toFile = $srcFile;}$info = "";$srcInfo = GetImageSize($srcFile,$info);switch ($srcInfo[2]){ case 1: if(!$cfg_photo_type['gif']) { return false; } $im = imagecreatefromgif($srcFile); break; case 2: if(!$cfg_photo_type['jpeg']) { return false; } $im = imagecreatefromjpeg($srcFile); break; case 3: if(!$cfg_photo_type['png']) { return false; }

$im = imagecreatefrompng($srcFile); break; case 6: if(!$cfg_photo_type['bmp']) { return false; } $im = imagecreatefromwbmp($srcFile); break;}$srcW=ImageSX($im);$srcH=ImageSY($im);if($srcW<=$toW && $srcH<=$toH ){ return true;}//缩略生成并裁剪$newW = $toH * $srcW / $srcH; $newH = $toW * $srcH / $srcW;if($newH >= $toH){ $ftoW = $toW; $ftoH = $newH;}else{ $ftoW = $newW; $ftoH = $toH;} if($srcW>$toW||$srcH>$toH){ if(function_exists("imagecreatetruecolor")) { @$ni = imagecreatetruecolor($ftoW,$ftoH); if($ni) { imagecopyresampled($ni,$im,0,0,0,0,$ftoW,$ftoH,$srcW,$srcH); } else { $ni=imagecreate($ftoW,$ftoH); imagecopyresized($ni,$im,0,0,0,0,$ftoW,$ftoH,$srcW,$srcH); } } else { $ni=imagecreate($ftoW,$ftoH); imagecopyresized($ni,$im,0,0,0,0,$ftoW,$ftoH,$srcW,$srcH); } //裁剪图片成标准缩略图 $new_imgx = imagecreatetruecolor($toW,$toH); if($newH >= $toH) { imagecopyresampled($new_imgx,$ni,0,0,0,($newH – $toH)/2,$toW,$toH,$toW,$toH); } else { imagecopyresampled($new_imgx,$ni,0,0,($newW – $toW)/2,0,$toW,$toH,$toW,$toH); } switch ($srcInfo[2]) { case 1: imagegif($new_imgx,$toFile); break; case 2: imagejpeg($new_imgx,$toFile,85); break; case 3: imagepng($new_imgx,$toFile); break; case 6: imagebmp($new_imgx,$toFile); break; default: return false; } imagedestroy($new_imgx); imagedestroy($ni);}imagedestroy($im);return true;}
