I'm wondering if there's a Photoshop plugin which will process an image in a particular way. It's a given that I could write my own, but the file formats are not particularly straightforward so it would be a lot easier to do in Photoshop. Or a similar app.
Essentially, I'm looking for something which can take an image and fill every transparent pixel with the color of the nearest opaque pixel until the entire image is filled up. It's to avoid sharp edges on masked textures when mipmaps are being used.
Alternatively, I do own FilterForge, so if anyone knows of a FilterForge Filter which will do the same thing, that would also be good.
