RTF Specification bug?

looseleaf · Post by **looseleaf** » Fri Dec 09, 2005 12:12 pm

Greetings!

We have troubles with getting line spacing to work properly with RichView.

The starting point is an RTF created by a TRxRichEdit component seomwhere else. This RTF code contains line spacing information which is lost when importing the RTF into our RichView or RichViewEdit.

The problem seems to be this sequence:

\sl400\slmult0

The specification I found at [0] says that if \slmultN with N=0 the "exact" or "at least the" line spacing that was defined in the \sl command before shall be used. If I manually change the \slmult0 to \slmult1, RichView works properly.

This is with 1.9.8 and Delphi 5. Wordpad loads the RTF file properly.

"At least" and "Exactly" kinds of line spacing are not supported by TRichView yet.

I see, nonetheless, it seems to work, if we manually replace the \slmult0 with \slmult1. But, as my boss just told me for he tried it, one line too late.

We'll experiment a bit.

\smult1 mode is supported. In this mode, \sl specifies a line spacing multiplier, and \slN means that line spacing is N/240*(single line spacing).
Info about N/240 is not included in that RTF specification, but it's true.

In \smult0 mode, \sl means a completely different thing - a distance (measured in twips or in points, not sure - another omission in RTF specification) between text base lines. This type of line spacing is not implemented in TRichView yet.
