bfif: brute force image finder
A very simple app that walks over a file or block device attempting to interpret the data as an image supported by stb_image (some but not all PNG, JPG, BMP, PIC, PNM, GIF variants) and writes out anything found as PNGs.
Usage
Simply takes the file to work on and then will output PNG files
for every image found that passes some basic sanity checks. Use
--ignore-false-positives=false (short version -i false.)
