Extrangle [Y] coordinate in a Geom:Point generated with controlPontPosition::selectAll
Hi to all. Posted in IRC, no rsolve. New attemt, maybe this is a better plaze for this type of cuestions. Im attemting to fit identical, the position of 2 Geom:Points, one generated by Inkscape::UI::controlPontPosition::allNodes() and a cast to Inkscape::UI::Node->position() and the other with first_segment()->initialPoint(). The values need to be the same but one return 154.13750999999999, 406.75175261718755 and the other 154.13750999999999, 645.61042999999995. Whith other node/segment the values are -74.927954, 664.71799261718752 and -74.927954, 387.64418999999998. The value with initialPont is similar -rouded- than in the SVG. I test to pass to the other desktop->w2d,desktop->d2w, and normaliza(), with no luke. What im doing bad? By, Jabier.
it looks like one of these points is in SVG coordinates while the other one is in UI coordinates, where the y axis is inverted. In both cases the sum of the y values is equal to 1052.36, which is the height of the default A4 size page.

You can also try the desktop to document coordinate transforms:
Geom::Affine doc2dt() const; Geom::Affine dt2doc() const; Geom::Point doc2dt(Geom::Point const &p) const; Geom::Point dt2doc(Geom::Point const &p) const;
Cheers, Johan
Thanks very much!!! thats exacly what i neeed.
