Hi,
Is there any way to implement (or is it already
implemented?) arbitary rotation of the drawn objects?
I'm writing (okay, trying to write, once I get more of this SVG
stuff figured out) a chemistry template for DIA. I think with good design
on the template's part DIA could beat out most Windows based Chemistry
structure drawing programs that I've seen (with the exception of ChemDraw
Ultra, but that's a $1500.00 program). The problem, of course, is
rotation of the bonds. I *can* code in the bonds at the most common
orientations (ie, 30 degrees, 60 deg, 72 deg, 104.9 deg, etc...) but it
would be MUCH more elegant to implement.
Since SVG is just vectors, rotation would just mean multiplying
the coordinates of the vector with a certain matrix (Need to dig out my
linear algebra book on that, but it shouldn't be difficult to
implement...). What do you all think?
