Hmm, can you please ZIP or so the file & reattach? It doesn't seem to be possible to download a .tif file here

Quite possible for me. Downloaded, zipped.

Fixed, tiff was set as an image, thus displaying inline. But browsers mostly does not support tiff format. Changed to raw binary data, should be better.

I can confirm the bug.
PictView show a garbbled image. IrfanView on the other hand is just fine.

The file seems violating the specification, it wrongly stores padding bits and EOL markers. Anyway, I added a workaround to deal with such files for the next version of AS (2.55b1? 2.60b1?).

How was the file created? It is worth a shot to contact developers of the software and make them aware of the spec violation...

This sample file comes from example files shipped with vectorizer program: AlgoLab R2V Toolkit
