this is my code where something goes wrong:
$handle = fopen($tmpHolder, "rb"); // opent 'temp/tmp.img'
echo $handle;
$contents = fread($handle, filesize($tmpHolder));
if($original = imagecreatefromstring($contents)){
}
else{
// nog een keer
if($original = imagecreatefromstring($contents)){
}
else{
exit("mislukt, probeer het opnieuw<BR>");
}
}
$source = imagecreatefromstring($contents);
$original_width = imagesx($original);
$original_height = imagesy($original);
if($original_width < $formaatSmall){
$newwidth = $original_width;
$newheight = $original_height;
}else{
$percent = ($original_height/$original_width);
if($original_width>$original_height){
//horizontaal
//percent < 1
$newwidth = $formaatSmall;
$newheight = $formaatSmall*$percent;
}
else if($original_width<$original_height){
//verticaal
//percent > 1
$newwidth = $formaatSmall/$percent;
$newheight = $formaatSmall;
}
else if($original_width=$original_height){
//vierkant
//percent = 1
$newwidth = $formaatSmall;
$newheight = $formaatSmall;
}
}
$thumb = imagecreatetruecolor($newwidth, $newheight);
if (!imagecopyresized($thumb, $source, 0, 0, 0, 0, $newwidth,
$newheight, $original_width, $original_height)){
exit("aanmaken van thumbnail mislukt<BR>");
}
$thumbnail = $folder_small."/".$form_bestandsnaam;
if(!is_file($thumbnail)){
$handle2 = fopen($thumbnail,'x');
chmod($thumbnail, 0777);
fclose($handle2);
}
imagejpeg ($thumb, $thumbnail, 60);
fclose($handle);
