"z3n666" added a nice function but i had a problem to use ImageCreateFromXXX with a full
path so i changed the function by adding the "@" sign in some places...
function _ckdir($fn) {
if (strpos($fn,"/") !== false) {
$p= substr($fn,0,strrpos($fn,"/"));
if (!is_dir($p)) {
_o("Mkdir: ".$p);
mkdir($p,777,true);
}
}
}
function img_resizer($src,$quality,$w,$h,$saveas) {
/* v2.5 with auto crop */
$r=1;
$e=strtolower(substr($src,strrpos($src,".")+1,3));
if (($e == "jpg") || ($e == "peg")) {
$OldImage= @ImageCreateFromJpeg($src) or $r=0;
} elseif ($e == "gif") {
$OldImage= @ImageCreateFromGif($src) or $r=0;
} elseif ($e == "bmp") {
$OldImage= @ImageCreateFromwbmp($src) or $r=0;
} elseif ($e == "png") {
$OldImage= @ImageCreateFromPng($src) or $r=0;
} else {
_o("Not a Valid Image! (".$e.") -- ".$src);$r=0;
}
if ($r) {
list($width,$height)=getimagesize($src);
// check if ratios match
$_ratio=array($width/$height,$w/$h);
if ($_ratio[0] != $_ratio[1]) { // crop image
// find the right scale to use
$_scale=min((float)($width/$w),(float)($height/$h));
// coords to crop
$cropX=(float)($width-($_scale*$w));
$cropY=(float)($height-($_scale*$h));
// cropped image size
$cropW=(float)($width-$cropX);
$cropH=(float)($height-$cropY);
$crop= @ImageCreateTrueColor($cropW,$cropH);
// crop the middle part of the image to fit proportions
@ImageCopy(
$crop,
$OldImage,
0,
0,
(int)($cropX/2),
(int)($cropY/2),
$cropW,
$cropH
);
}
// do the thumbnail
$NewThumb= @ImageCreateTrueColor($w,$h);
if (isset($crop)) { // been cropped
@ImageCopyResampled(
$NewThumb,
$crop,
0,
0,
0,
0,
$w,
$h,
$cropW,
$cropH
);
@ImageDestroy($crop);
} else { // ratio match, regular resize
