So I've been resizing texture patches for a while now, when not all resolutions are available. However, I'm not sure if I am doing it the "best" way I possible could. So my question is, what is the best resizing method, using GIMP?Keep in mind that since I am doing this on released patches, I do not have access to the PSDs, and so can't use the absolute best method of scaling the vectors. This questions is for both downscaling and upscaling. Currently I am using the cubic method to both downscale and upscale, and doing nothing else. I have heard in some of Han's threads that he uses filtering in addition to the scaling. Also I would like to know what the standards are for various image types. I know, for example, that GUIs are 256x256 for 16x, 512x512 for 32x, and 1024x1024 for anything greater and items and blocks are the size the number references. However, for things like GUI buttons (on a separate sheet from the GUI), overlays, mobs, particles, etc. Things seem to be less cut and dry.
So specifically I want to know:
* What method to use to downscale/upscale
* What additional techniques, if any, should I apply
* Is it better to just leave lower resolution patches be themselves in a high resolution pack
* How can I get a batch operation to ignore png offsets in patches that have been unstitched
* What are the "standards" for the sizes of various types of images.
If you don't have an answer for GIMP, but do have an answer for Photoshop/Creative Suite, then go ahead and post it anyway, as GIMP usually has most of the same operations, they just require translation. Do not post anything that requires a PSD or XCF as I will typically not have access to those. Maybe this could become a staple resource if a good, comprehensive answer is given. Thanks in advance.
