Specifies the "pixels per inch" value used when converting metafiles to bitmaps.
property MetafilePixelsPerInch: Integer;
(introduced in version 17)
Metafiles (in pictures and hot-pictures) are printed as bitmaps, if NoMetafiles = True. This property allows changing a pixel density of these bitmaps. Larger values produce results of higher quality, but require more memory (when printing to PDF using some third-party library, larger values produce larger PDF files).
For example, you can assign 300 to this property.
0 (default bitmap sizes).
