ilbm.js's Introduction

This project contains code to display IFF/ILBM files (as used on the Amiga) and display them in HTML5 browser using Javascript + Canvas.

The project is described on my blog.

The library currently handles the following image types:

  • Color palette images
  • EHB (Extra Half-Bright) images

  • RGB-24 images.
  • SHAM (Sliced HAM) images

The library handles the following features:

  • Uncompressed and Packbit compressed data
  • Non square pixel rendering
  • Colour-palette animations

ilbm.js's Issues

Unknown ILBM IFF Format - Colors Wrong

So, I tried this ilbm javascript web program, and it opened many IFF images. However it was unable to open a specific ILBM IFF I have. So, I edited the iff.js file. Now it opens the IFF file but the image is noisy and the colors are completely wrong.

I have included an image of how it is displayed in the js application which I edited to actually open it, and how it should look like.
The IFF image is included with the edited application.
