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 now) where I
have added code that to some extent can do the job. You 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.
