tng
A full-featured PNG renderer for the terminal, built for blessed.
Convert any .png file (or .gif, see below) to an ANSI image and display it
as an element or ANSI text.
Blessed uses an internal from-scratch PNG reader because no other javascript PNG reader supports Adam7 interlaced images (much less pass the png test suite).
The blessed PNG reader supports adam7 deinterlacing, animation (APNG), all color types, bit depths 1-32, alpha, alpha palettes, and outputs scaled bitmaps (cellmaps) in blessed for efficient rendering to the screen buffer. It also uses some code from libcaca/libcucul to add density ASCII characters in order to give the image more detail in the terminal.
.gif files are also supported via a javascript implementation (they are
internally converted to bitmaps and fed to the PNG renderer). Any other image
format is support only if the user has imagemagick (convert and identify)
installed.
