Image support #18

Closed dankamongmen closed 4 years ago

dankamongmen commented 4 years ago

We ought be able to do decent image support via Unicode blocks and mapping the color palette to match the image. http://nullwise.com/image_in_terminal.html

To do this really well, I think we'd want to leave most of the image processing in the hands of a library that knows how to do it well, and then blit the result to the screen. So your target would be 256-indexed colorspace (GIMP can generate optimum palettes for sure), scaled to the terminal character resolution (taking into account unicode blocks and aspect ratio of characters).

the rust program viu appears to generate much higher quality than imgpreview.

that looks pretty nice!

mpv -vo tct is quite comparable to viu. both are superior to imgpreview.

We're never going to reach this quality level without directcolor, which (see #56) is unlikely to work with ncurses. The best we can do is quantize down to 256 colors.

fuck it, this will be an notcurses thing
