SYMPTOMS
The edges or hairline borders around charts, graphs or graphic images in Quattro Pro spreadsheets do not print on 300 dpi PostScript printers. They may print with reduced width on 600 dpi (or better) PostScript printers. Complete images print to non-PostScript printers.
CAUSE
PostScript does not deal with clipping properly in the GDI model. GDI is inclusive/exclusive while PostScript is inclusive/inclusive. In a rectangle from (1,1) to (2,2), GDI lights the pels at (1,1) only. PostScript would light the pels at (1,1), (1,2), (2,1) and (2,2).
Quattro Pro generates a clipping region by creating a very large rectangle, intersecting it with the desired drawing area, then using a series of PatBlt's to output the edges with very precise coordinates. The difference in clipping between GDI and PostScript makes some of the lines (pels) disappear.
STATUS
Microsoft has confirmed this to be a problem in Windows NT version 3.5. We are researching this problem and will post new information in the Microsoft Knowledge Base as it becomes available.
