edisplay - fast image viewer
edisplay [--gl] file...
ExactImage is a fast C++ image processing library. Unlike many other library frameworks it
allows operation in several color spaces and bit depths natively, resulting in low memory
and computational requirements.
edisplay loads the specified images, one by one, and displays them on a X-server (or other
display device if the minimal abstracted needed is added).
In the top-left corner a tiny, shaded on-screend-display shows the current cursor position
as well as the color value of the pixel.
For images including an alpha channel a checkboard is displayed in the background.
Utilize OpenGL for rendering.
Display help text and exit.
