I'm looking at the PDF demo, and I notice this in the block to read an RTF file:

             srve.RichViewEdit.Clear;
             srve.RichViewEdit.DeleteUnusedStyles(True, True, True);
             srve.RichViewEdit.LeftMargin := 132;
             srve.RichViewEdit.RightMargin := 57;
             srve.RichViewEdit.TopMargin := 94;
             srve.RichViewEdit.BottomMargin := 94;
             srve.RichViewEdit.LoadRTF(OpenDialog1.FileName);
             srve.RichViewEdit.Format;

The latest version of RV/RVE has DocParameters to get the margins and such from the RTF file. So my question is, are these now loaded automatically? Or can they be set after the call to LoadRTF? Specifically, which of these is most appropriate:

Code: Select all

             srve.RichViewEdit.Clear;
             srve.RichViewEdit.DeleteUnusedStyles(True, True, True);
             srve.RichViewEdit.LoadRTF(OpenDialog1.FileName);
             srve.RichViewEdit.Format;

or

Code: Select all

             srve.RichViewEdit.Clear;
             srve.RichViewEdit.DeleteUnusedStyles(True, True, True);
             srve.RichViewEdit.LoadRTF(OpenDialog1.FileName);
             srve.RichViewEdit.LeftMargin := Floor(srve.RichViewEdit.DocParameters.LeftMargin);
             srve.RichViewEdit.RightMargin := Floor(srve.RichViewEdit.DocParameters.RightMargin);
             srve.RichViewEdit.TopMargin := Floor(srve.RichViewEdit.DocParameters.TopMargin);
             srve.RichViewEdit.BottomMargin := Floor(srve.RichViewEdit.DocParameters.BottomMargin);
             srve.RichViewEdit.Format;

Thanks

I tried this both ways, and they seem to be equivalent, leading me to believe the library already accounts for DocParameters.

(The code I gave needs to have the numbers converted from the input units to pixels, and I did that.)

I noticed, however, that while the Top, Bottom, and Left margins look ok, the Right margin is not respected.

TRichView itself never reads LeftMargin and other margin properties from RTF. It can read DocParameters property if RTFReadProperties.ReadDocParameters = True.
As for ScaleRichView specifics, I'll ask Ilya.

Thanks, I have corrected a bug. ScaleRichView incorrectly read out values of Margins and incorrectly save them in DocParameters for RTF files. In the nearest updating it will be fixed.

So what is the recommended approach after the fix is released?
