Imagefilter() seems to do nothing

Recommended Posts

Hello everyone,

I have php5 on my server and I am trying to use the imagefilter function found here:

[a href=\"http://us2.php.net/manual/en/function.imagefilter.php\" target=\"_blank\"]http://us2.php.net/manual/en/function.imagefilter.php[/a]

to apply the IMG_FILTER_SMOOTH and the IMG_FILTER_GAUSSIAN_BLUR filters. However it seems that neither of these filters actually make a difference. My image is just as pixelated as it was previously. Am I doing something wrong? IMG_FILTER_SMOOTH requires a 'smoothness' argument, so I put in some ridiculous number like 10000000 because I couldn't find any information on the range required for this argument on the web.

Anyways, any suggestions would be appreciated.
