    There is an options button on the Save dialogue. On the options dialogue you can choose the filter and the compression strength.

    Yes. No filter seems best for dialogue boxes — which I suppose is why its the default setting. I think PNGOUT is just a waste of time. Other methods seem much faster, and often better too.

    I agree, a waste of time. I tried PNGOUT a couple of occasions, but it didn't bring extra value imo.
    And the shareware plugin has a filesize limitation. So I stopped using it.

    The "button" wasn't visible on my computer. It turned out I had click on the format description text. There are a lot of options, looks like they took the same graphics library as was used in Coffee Cup. I've not seen RGB-JPEG anywhere else.

    One important setting is missing though, you can't turn off color subsampling. On the "Preferences Fonts" sample the deffect is easily "abx"-able when you look at the red 'close' button and most of the Clear-Typed text.

    What is this size limit you've been mentioning? I did notice that Ken Silverman is selling a version for money, but the IV pluging does not say shareware anywhere. PNGOUT is irreplaceable in one specific case. It is one of the rare programs that can process transparency. IrfanView cannot.

    It's a long time ago, but it was something like 65 KB.
