How to Run and Compile on Cygwin

[E3V3A]

I've managed to compile this on Cygwin (under Win 8.1) using the following patch:

Yeah, you need MinGW for Cygwin.

The output works for a small and original PNG:

The Original:

The Result (in Cygwin Bash):

In ConEmu (PowerShell 5.1.1)

---

• trying to output the png you included in ./image/*.png silently fails.
  (Please add real png for testing!)
• Running this in PowerShell fails on most systems not using ConPty or newest ConHost.
  (I.e. on OS < Win10)
• If your terminal window is smaller (in character count) than the image pixel count (in any direction) the image gets broken up.
• Also works on ConEmu, but look very ugly!

It should work with any size image, with any size terminal, without breaking up the image.

Did you try my pre-built windows binary to see if it behaves better? If so, there may be something wrong with the cygwin build?

Yes, your pre-built only show a few pixels, like in the other issue, so much worse.
