Turn images into text better than caca/aalib

Latest commit 86febc9 Jul 7, 2016 @jart Configure gflags without using pkg-config
This is an attempted fix of #38.

I would prefer to use AC_CHECK_LIB, but since it's a C++ library that's
not exactly trivial.

Rendering Modes

xterm256

By default, hiptext assumes you're using an xterm256 compatible terminal, e.g. gnome-terminal, without bothering to check the TERMINAL environment variable.

To double the number of pixels using Unicode half blocks, consider using the following option, which may become the default in the future:

MacTerm

The most beautiful terminal for hiptext is the one built into Mac OS X called Terminal.app. This terminal uses xterm256 but it's implemented using a custom color palette that was chosen by designers rather than engineers.

But the interesting thing about this palette is that it uses slightly different colors for foreground and background. By using Unicode half blocks, this allows us to simulate something closer to 512 colors!

However to use this, you must be using the black color scheme. After all, why would you use anything else?

Unicode

If you want to render an image without the ANSI color escape codes, you can use the --nocolor flag. This will render the image using shaded unicode block characters.

ASCII

The no-color mode supports a very simple character quantiser that can convert images to ASCII. Please understand that if this is what you want, there are much better tools for the job, like cacalib.

SIXEL

If you use a SIXEL terminal, e.g. mlterm >=v3.1.3, then the following flags can provide much more minute rendering:

hiptext --sixel256 balls.png           # For 256-color SIXEL terminal such as mlterm (>=v3.1.3)
hiptext --sixel16 balls.png            # For 16-color SIXEL terminal such as xterm(patch level >= #294) with "-ti vt340 option"
hiptext --sixel2 balls.png             # For monochrome SIXEL terminals

Configuration

Background

By default, hiptext assumes that your terminal background is black. If this is not the case, you can specify your background color using a CSS or X11 color string.
