Another round of pain in converting to a new version of Filemaker. The first round was Filemaker 11 to 12. Now it is Filemaker 12 to 13. The updates before Filamaker 11 went a lot smoother.
Looks like all of the images need to be converted to pngs with an alpha channel so that you don't wind up with white backgrounds.
There is nothing to do about text rendering other than to again make modifications to show them the best you can. It is like doing a crossplatform solution covering Mac and Windows. The text rendering is slightly different in each so you have to choose a compromise font size.
Filemaker 13 finally works as expected on mac as far as font style is concerned. With filemaker 12 (or even 11, 10 or 9), Bold or Italic styles were actually applied twice on mac. If you wanted to have a normal bold or italic style, the solution was to select to bold font or the italic font directly from the font list (they don't appear in the font list anymore in 13)
As far as the released picture is concerned, what happens if you change the background color to transparent or to none?
