I have an ePub project I am laying out in InDesign CC 2014 and have placed all images into a graphic frame with a 6 point stroke and a drop shadow. When I export to ePub 3.0 Fixed Layout the drop shadow is not preserved and the border appears offset displaying an unexpected white area around the image. When I select PNG as a conversion option or Automatic (PNG) the drop shadows are preserved and the border is in correct without any white border areas.
There is a significant difference in resulting exported file—70 MB (PNG) vs. 30 MB (JPG). This export represents 1 chapter out of 13 and has significantly fewer images. Your help is most appreciated.
I forgot to clearly state, "When I export to ePub 3.0 Fixed Layout using the JPEG option the drop shadow is not preserved and the border appears offset displaying an unexpected white area around the image.
Sorry for not including this. David
Could it be something to do with the fact that PNG allows transparency and JPG doesn't?
