<p dir="ltr">Thanks a lot for the quick and helpful responses! I'll keep you updated if I find any other oddities.<br>
I'm currently trying to add 8-bit depth support to the JPEGReadWriter plugin in order to be able to write 8-bit deep images to disk. I'm using the Cog VM since I'm running Cuis (it provides some very helpful image processing related packages), which is based on a non-Spur Squeak image.</p>

Hello, everyone,<br>
<br>
I've been trying to simulate the Cog V3 VM using the snippets provided<br>
in the VMMaker image with no success. The VM seems to start up fine<br>
until it tries to perform a full GC, which raises a debugger with the<br>
following message: 'MessageNotUnderstood:<br>
InLineLiteralsManager>>backEnd'<br>
<br>
The image built using the provided scripts shows a lot of messages<br>
related with undelcared variables and some of the snippets in the<br>
different workspaces include unimplemented messages (e.g.<br>
#removeUnneededBuiltins, present in the Slang test workspace, lacks<br>
implementors in this image). I suspect something could've gone wrong<br>
during the automatic package loading process. However, I seem to have<br>
all the necessary changesets installed (telling from a quick<br>
inspection of the repository using Monticello).<br>
<br>
I'm not familiar with the inner workings of the VM and have been<br>
working on this only very recently, so my apologies if I seem to be<br>
asking something obvious.<br>
<br>
Thanks in advance,<br>
<br>
