Version

XFRX 18.0

Symptoms

  • Default picture format is not changed or chanched to BMP.
  • EMF image displays black box.

Cause

Because PDF doesn't support EMF, than XFRX converts EMF to image specified by DefaultPictureFormat property. EMF contains alpha chanel (pixelformat 32bpp+Alpha), but GDI+ return pixelformat 32bpp only.  BUG in convert functions  (in xfrxlib.fll) modify bpp value to 4.

Workaround

Change DefaultPictureFormat to another value than BMP.

m.loSession.SetOtherParams("DEFAULTPICTUREFORMAT", "PNG")

Hotfix

xfrxlib.fll for XFRX 22.6, 22.5, 22.4, 22.3, 22.2, 22.1, 22.0
