Hi, all. I am trying to use a script to edit inkscape SVG code, and mostly succeeding, except with coordinate values. Specifically, with text objects, there seems to be some tricky function generating the "x" and "y" values (object coordinates). The function seems to be tied to the transform values. With no transformation in effect (theoretically, with the matrix being (1,0,0,1,0,0) -- i say theoretically because the line is absent when these are the (implied) values), the "x" and "y" values are what one would expect, when one drags the object left and right, up and down. The x and y values change in the expected manner. However, when the text object gets transformed, as in the example below: transform="matrix(0.42584538,0.90479595,-0.90479595,0.42584538,0,0)">
transform="matrix(0.42584538,0.90479595,-0.90479595,0.42584538,0,0)"
the x and y values become severely strange... Dragging the text object vertically affects the x value (as well as the y value), and horizontal drag affects both as well. The values become negative in an unexpected way. And visually, the objects are not where the script attempts to place them.
Could someone please clue me in about the function (the math of it)?
thanks in advance
