Prototype application for converting UnQuill output to other formats.
This was designed as a way to explore the issues in converting old 8-bit adventure games. It may well work with a variety of games, but has not been thoroughly tested and is no longer under active development.
At the time of writing, the 8-Bit Adventure Toolkit is being written based on lessons learnt here. Bug reports and feature requests are welcome, but are more likely to be included in that project than back-ported into this one.
-
Get a snapshot of your game, as described on the main site
-
Decompile your game with UnQuill:
./unquill*/unquill mygame.sna > mygame.txt -
Generate PNM and SVG versions of the graphics:
./script/the_inker.pl --out=mygame-graphics/ mygame.txt -
Optionally convert PNM images to GIF (see below):
./script/convert-to-gif.sh mygame-graphics/ -
Optionally convert the game to ngPAWS format:
./script/the_translator.pl --out=mygame-ngpaws --images=mygame-graphics mygame.txt
Normal image formats are based on raster graphics - they specify the colour of each pixel in a grid. SVG uses vector graphics instead - it specifies properties of abstract shapes. Quill "images" aren't exactly images at all, they're more like little programs that draw images using a mixture of raster- and vector-like commands.
To create PNM images, The Inker works like an emulator that runs Quill image-programs. It should create perfect replicas of the images that would be created by The Quill.
To create SVG images, The Inker translates image-programs from The Quill's language to SVG's language. This should produce attractive results in most cases, but can have difficulty translating some commands.
SVG images tend to be a less accurate representation of the original, and often need to be cleaned up manually before they look right. But unlike raster images, they can be made to look good at any size without recreating the image from scratch.
There are many SVG editors available - you can even edit SVGs in Notepad - but Inkscape is probably the most widely-used.
This prototype produces PNM images because it was more convenient during development. The actual images created by The Quill are more similar to GIFs - they can have one or two frames, and up to 16 colours.
If you want to convert your PNM images to GIF and have installed ImageMagick, you can use convert-to-gif.sh to convert them:
./script/convert-to-gif.sh mygame-graphics/
Alternatively, you can create GIFs with your favourite graphics package:
- Load any
<room>-a.pnmimage - If there is a
<room>-b.pnm, load<room>-b.pnmas a second frame in the image - set each frame to display for 320 milliseconds
- Save the image as
<room>.gif
Creating GIFs is entirely optional - most graphics packages support PNM, and you might prefer to work with SVG images anyway.
