This tool is a generic image conversion tool for the Data Frog SF2000. You can use it to convert the SF2000's raw image data files to PNG, and convert PNG/JPEG images to RGB565 format (a reduced colour mode used for most of the SF2000's UI elements), or BGRA format (the flavour of transparent images used by some SF2000 UI elements). You can also choose a variety of scaling or filtering modes when converting to an SF2000 image. Please note this tool is provided as-is; make sure you have backups of anything you care about before potentially replacing any files on your SF2000's microSD card! 🙂
This tool can operate in two main modes - you can use it to convert from an SF2000 format to RGB888/RGBA, or you can use it to convert to an SF2000 format from RGB888/RGBA. Choose the mode you want, and follow the next instruction that appears.
