I am dabbling with in-cell rendering of molecules and proteins in
Calc. I have made a custom build of DEV300_M60 (I know - it's old

can take a look at my progress so far at
http://www.biochemfusion.com/work/in-cell/status1.html
I haven't found myself able to sufficiently grok the logic in
output2.cxx's ScOutputData::DrawStrings() so I can override the cell
rendering reliably enough. Also, I could use a hint as to how I
should implement proper preview and print support - seems like it is
mostly a matter of scaling (?).
ScOutputData has member variables nPPTX and nPPTY for the factor of
pixels per twip. Just use those instead of a fixed factor, and scaling
will adjust to the printer (or different zoom in the view).
There is still a special case to be handled though: If the
configuration option "User printer metrics for text formatting" is
set, the bPixelToLogic parameter to DrawStrings is TRUE, and
PixelToLogic / LogicToPixel has to be used.
Thanks Niklas. That should get me going with the preview / printing.
Can anyone give me input on what variables / flags I should set to
really override cell drawing and effectively get OwnerDraw mode in
specific cells ? I am currently changing bNeedEdit when I encounter a
"molecule-formatted" cell so I can do cell rendering instead of the
in-place editor doing it (as far as I have understood the meaning of
that flag).
I have also tried changing bDoCell but with somewhat unpredictable
results. Is this caused by cell rendering also being done in other
places than ScOutputData::DrawStrings() ?
Cheers
