Attached is the typed scheme wrapper for file/gif.<br><br>One challenge I ran into is that I needed argb-bytes? as an opague type but it's not exported. I couldn't find how to define an function as an opague type within the same module, so I had to patch file/gif to export argb-bytes? instead.<br>
<br>Let me know if there are different way of handling this issue. Thanks,<br>yc<br><br>
