[QUOTE="mystic_fm, post: 784262, member: 28538"] The performance of any given resizer can be significantly affected by both the image content and the type of resizing (direction and degree). There are a number of different algorithms available for resizing (nearest pixel, bilinear, bicubic, etc.), each of which may perform better or worse based upon those variables. That's why imaging software such as Photoshop provides several algorithm options for image resizing, so that you can experiment with them and choose the method that works best for your particular needs. (I don't know what sort of algorithms come with Gimp, as I don't use it.) Preview has both a nearest pixel algorithm (the default) and what appears to be sort of a bilinear algorithm (the "resample image" checkbox). But the latter produces fuzzier results and seems to lose more information than Photoshop's implementation of bilinear, especially on text or other finely detailed elements, so I'm not sure what they are actually using. Preview might be enough for your needs; at least try it and see if you are happy with the results. [/QUOTE]
