agi-upscale
This is a tool written in Ruby to upscale old Sierra AGI game backgrounds. It was the basis for a short video I authored:

Installlation
-
Check out the repo
-
Make sure you have ImageMagick installed.
-
Run
bundle installto install dependencies
Usage
You need to supply it with a directory containing the DOS version of an AGI Sierra game, and the id of the picture you want to upscale.
Example:
$ ruby pic.rb kq2 3 3.png
That will render pic 3 from kings quest 2 at an upscaled resolution.
If you want to extract all backgrounds from a game you can do this, assuming output is an
empty subdirectory for the output images.
$ ruby pic.rb kq2 all output
