Re: Magenta color blotches... is the CPT file format truly
lossless?

Hi Sean,

I applaud your efforts to want to ensure everything is OK.

Here is a test file I'd like you to quickly try, you are familiar with 
your testing process.

It's here are lossless 24 bit PNG, and covers pretty much the whole 
spectrum. If anomalies appear, they should be revealed more readily in 
this case.

I see the blotches in your prev. examples, but for the moment let's 
leave jpeg out of the equation - at every stage.
