PNG Export Quality
There is a huge difference in the rendering quality of JPEGs vs PNGs in InDesign.
See attached document that demonstrates the difference between the two formats, exported from the same InDesign document, using maximum quality, 72 DPI with anti-aliasing turned on.
The obvious differences are the moiré in the white top and the edges of the legs in the girl at the bottom, including the fine detail in the stitching.
It would be great if the PNG export engine could be improved.
