    PNG Advice to beginners in Captivate

    Nicketlareriksen Community Member

      Hi beginner,

       

      I have ecountered some problems with PNG and transparency - background becomming black etc. Various effects adds to the confusion. It is in fact not a bug or a problem - but a behaviour that simply needs some attention (usability work) in my opinion.

       

      I find that this is not such an "intuitively obvious" setting and I would like to share my experience since I have seen some posts on this subject. None, however, have referred to this detail as the cause of the problem.

       

      I failed to notice the connection between the "Quality setting" in the "General" properties box. When you import an image on a slide (or Copy one from another slide) you need to make sure that the Quality setting on that particular slide is "High - (24 bit)". Captivate doesn't help you on this - or give you a warning - and if you miss this little detail, then the slide will not export/publish the way you expect. Viewing in Captivate works fine, but output is adjusted to this setting, causing 24-bit PNGs with transparency to look "corrupted" and you will no doubt spend time reimporting, saving etc. since the slide view works fine.

       

      Don't - just don't miss the setting. It is one of those things you have to be aware of.

       

      Kind regards,

       

      Nick

          Nick, great call on pointing this out.

           

          I was freaking out about my PNGs with transparency until I finally figured this out as well.

           

          One thing that helps is to select all the slides in the Filmstrip view and then apply the quality settings to all of them at once.

           

          1. Right-click on one of the slides.

          2. Select All Slides.

          3. In the Properties Palette, under General, set to the quality to Optimized or High.

           

          If you have lots of slides it will take a moment to churn through them.
