catpix's Issues

See whether MiniMagic would work instead of rmagick

please document the sytem lib dependencies

the gem seems to depend on libmagickcore-dev and libmagickwand-dev. I had installed the regular packages but still could not build the native extensions.

thank you.

also with rmagic

Return image instead of printing

Would it be possible to return the image as a string instead of printing it directly to the screen?

Try using unicode characters to double the resolution

We could use only one character for the pixel split into two colours using the Unicode "Upper Half Block" character (U+2580 - ▀ and ▄) with foreground and colouring the rest with background colour.

Add some tests

This gem rocks, I was thinking about adding some tests (maybe rspec).
Specs will make code refactor easyer.
