Make Me Small!

Simple image downscaling methods for Unity textures2d. Includes 1. Subsampling 2. Box downscaling (= Average filter) 3. Bilinear 4. Bicubic 5. Gaussian (5x5) 6. Perceptualy based donwscaling [A. C. Oztireli et al., SIGGRAPH 2015] 7. Content-Adaptive Image Downscaling [J. Kopf et al., SIGGRAPH Asia 2013]. Perceptualy-based donwscaling is slow, but would produce best quality when you downscale real-world images. Content-aware downscaling is extremely slow, but would produce best quality when you generate a pixel art by donwscaling a cartoon image. All of them are implemented in C#. It does not use shaders nor materials. How to use 1) Import MakeMeSmall.unitypackage 2) If you want, just open the following demo scenes to see demonstrations. - Demo/Scenes/1_Simple You can run downscaling methods by clicking buttons. - Demo/Scenes/2_FileConverter You can load a PNG image on your disc, downscale it, and save the downscaled image on your disc. - Demo/Scenes/3_FolderConverter You can downscale all PNG images in a folder. 3) To downscale a texture in your C# script, just do like: Texture2D outputTexture2D = MakeMeSmall.Downscale.Subsample(inputTexture2D, new Vector3(w, h, 0));
