Image manipulation

[DaveSMR]

I guess this would be one for the developers.

I've been working on a site that uses php's imagecopyresampled() function to resize image to required dimensions. All works okay but some images (particularly those with straight lines) have a slightly poor quality.

Having done some reading it sounds like I'd get a better result using the Imagemagick library in php and this leads me here. Has anyone done this before, or does anyone know if it would be possible to install this library so that SD can make use of it?

I use imagecopyresampled in many add-ons and there must now be thousands of users. No-one has ever complained about image quality.

It might be possible to call ImageMagick from PHP but sounds like a lot of work for little gain.

That sounds about right. I have given up on this, and with a little good advice I settled on creating the images server side.

The images created using imagecopyresampled are far from horrible but when presented with the output image vs those created using the old method (some form of batch script through image editing software, as I understand it) the difference is obvious. I was seeking to provide better functionality without compromising on quality.
