Reply To: PDF export: circle icon has a flat tire

Well, yes… if it was originally an AI graphic, then it would be much better to keep it as a vector artwork and place it in InDesign as an AI or PDF file. Rasterized (bitmapped) images can get changed in many ways and will never be as clear or sharp as vector lines.

Your comment about PSDs with transparent backgrounds also made me think of this old post:

I think that was mostly fixed, but it may still be helpful.
