PHPCMS如何解决缩略图不清楚

首先在phpcms下面的libs中找到classes目录并打开；然后找到“image.class.php”这个文件并打开；最后搜索到调用“$imagefun()”函数的地方并传第三个参数为90即可。

搜索到下这个函数function thumb($image, $filename = '', $maxwidth = 200, $maxheight = 200, $suffix='', $autocut = 0, $ftp = 0) {if(!$this->thumb_enable || !$this->check($image)) return false;$info= image::info($image);if($info === false) return false;$srcwidth= $info['width'];$srcheight = $info['height'];$pathinfo = pathinfo($image);$type =$pathinfo['extension'];if(!$type) $type = $info['type'];$type = strtolower($type);unset($info);$creat_arr = $this->getpercent($srcwidth,$srcheight,$maxwidth,$maxheight);$createwidth = $width = $creat_arr['w'];$createheight = $height = $creat_arr['h'];$psrc_x = $psrc_y = 0;if($autocut && $maxwidth > 0 && $maxheight > 0) {if($maxwidth/$maxheight<$srcwidth/$srcheight && $maxheight>=$height) {$width = $maxheight/$height*$width;$height = $maxheight;}elseif($maxwidth/$maxheight>$srcwidth/$srcheight && $maxwidth>=$width) {$height = $maxwidth/$width*$height;$width = $maxwidth;}$createwidth = $maxwidth;$createheight = $maxheight;}$createfun = 'imagecreatefrom'.($type=='jpg' ? 'jpeg' : $type);$srcimg = $createfun($image);if($type != 'gif' && function_exists('imagecreatetruecolor'))$thumbimg = imagecreatetruecolor($createwidth, $createheight);else$thumbimg = imagecreate($width, $height);if(function_exists('imagecopyresampled'))imagecopyresampled($thumbimg, $srcimg, 0, 0, $psrc_x, $psrc_y, $width, $height, $srcwidth, $srcheight);elseimagecopyresized($thumbimg, $srcimg, 0, 0, $psrc_x, $psrc_y, $width, $height,$srcwidth, $srcheight);if($type=='gif' || $type=='png') {$background_color=imagecolorallocate($thumbimg,0, 255, 0);//指派一个绿色imagecolortransparent($thumbimg, $background_color);//设置为透明色，若注释掉该行则输出绿色的图}if($type=='jpg' || $type=='jpeg') imageinterlace($thumbimg, $this->interlace);$imagefun = 'image'.($type=='jpg' ? 'jpeg' : $type);if(empty($filename)) $filename= substr($image, 0, strrpos($image, '.')).$suffix.'.'.$type;$imagefun($thumbimg, $filename);imagedestroy($thumbimg);imagedestroy($srcimg);if($ftp) {@unlink($image);}return $filename;}然后找到if($type=='jpg' || $type=='jpeg') imageinterlace($thumbimg, $this->interlace);$imagefun = 'image'.($type=='jpg' ? 'jpeg' : $type);if(empty($filename)) $filename= substr($image, 0, strrpos($image, '.')).$suffix.'.'.$type;$imagefun($thumbimg, $filename);imagedestroy($thumbimg);imagedestroy($srcimg);改为if($type=='jpg' || $type=='jpeg') imageinterlace($thumbimg, $this->interlace);$imagefun = 'image'.($type=='jpg' ? 'jpeg' : $type);if(empty($filename)) $filename= substr($image, 0, strrpos($image, '.')).$suffix.'.'.$type;$imagefun($thumbimg, $filename, 90);imagedestroy($thumbimg);imagedestroy($srcimg);即可解决问题
