This article shows you how to solve the problem of unclear PHPCMS thumbnails, the code is concise and easy to understand, it will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

First, find the classes directory in the libs under phpcms and open it; then find the file "image.class.php" and open it; finally, search for the place where the "$imagefun ()" function is called and pass the third argument 90.

Search for the next function

Function thumb ($image, $filename ='', $maxwidth = 200,200, $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/$maxheight=$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, $srcheight); else imagecopyresized ($thumbimg, $srcimg, 0,0, $psrc_x, $psrc_y, $width, $height, $srcwidth, $srcheight) If ($type=='gif' | | $type=='png') {$background_color = imagecolorallocate ($thumbimg, 0,255,0); / / assign a green imagecolortransparent ($thumbimg, $background_color) / / set to transparent color. If the line is commented out, the green image} if ($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;}

And find it.

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)

Change to

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); the above is how to solve the problem of unclear PHPCMS thumbnails.
