Hello Brian,
Thanks, I fixed it though (by using another library.) heh.
- Ben
$imageObject = new ImageTransform( );
$imageObject->sourceFile = USER_IMAGES_PATH . $fileName;
$newFileName = substr($fileName, 0, strrpos($fileName,"."));
$newFileName .= '.png';
$imageObject->targetFile = USER_IMAGES_PATH . $newFileName;
$imageObject->resizeToHeight = 90;
$imageObject->resizeToWidth = 110;
if ( !$imageObject->resize( ) )
{
error_log($imageObject->error);
}

A few things to try:
- It might seem obvious, but first I'd confirm that the error_log is
acting as expected.
- After you first initialize the factory() object, check to see if
that creates an error.
- When calling "save" you're only passing the filename. I don't know
if you're perhaps using an older version of this, but according to the
documentation a 'type' parameter is also required. See docs here:
http://pear.php.net/package/Image_Transform/docs/latest/Image_Transform/Image_Transform.html#methodsave
Just a couple of other things that I noticed:
- The blank string in the factory() call isn't necessary (it defaults
to that anyway).
- If it does turn out to the be second parameter in save() causing
your problem, you might want to check your php.ini file to make sure
the E_WARNINGs are being displayed or handled somehow.
