meh (correctly pronounced with indifference) is a small, simple, super fast image viewer using raw XLib. It is similar to feh, but faster and simpler.
meh can use ImageMagick's convert executable, if it is installed, to view almost 200 file formats, including SVG and PDF, though it is slower for these formats.
Built in (fast) formats are JPEG, PNG, GIF, BMP, and netpbm.
