These determine the options used when saving PDF files (Tedds, Tedds for Word, batch design).
Drawings created in Tedds calculations use the vector format Enhanced Metafile Plus (EMF+) which provides the richest feature set and quality. However when documents are saved in PDF format not all of the vector information which is supported by an EMF+ image can be converted accurately to PDF format. To ensure that the integrity of the image is maintained this option can be enabled which will convert the image to a raster bitmap at a fixed resolution. The disadvantage of enabling this option is that the original vector images will not be scaled according to the final print quality and therefore may in some circumstances appear pixelated.
When Convert Enhanced Metafile Plus (vector images) to Bitmaps is enabled this option will determine the size of the bitmap image which is generated. The Low setting will create a drawing which is equivalent to 96 dpi. Good will increase the scale of images by 100%, High will increase the scale of images by 200%. When images are scaled the improved resolution comes at the expense of a larger PDF file.
