Unless the line has vector-effect="non-scaling-stroke" then it should scale as per the x and y scaling. -----Original Message----- From: Regina Henschel Sent: Sunday, March 06, 2016 4:48 PM To: www-svg Subject: Rendering of non-uniform scaled diagonal lines Hi all, I have problems to determine, how a line is to be rendered, if it is scaled different in x and y direction. Please look at the attached file (or use the source at the end of the mail in case the list does not allow attachments). It contains a group with kind "line" in Green kind "polyline" in Blue kind "path" in Red rectangle in Silver The stroke-width is so large, that the lines look like rectangles. I have repeated the elements, so that no other effects influence the rendering, but only the scaling. This group is stretched in x-direction by transform="scale(3,1)" and it is stretched in y-direction by transform="scale(1,3)". How should the result be rendered? I see in: Chrome (49.0.2623.75 m), Seamokey (2.39), The Gimp (2.8.4), Apache OpenOffice (4.1): All types, "line", "polyline" and "path" become parallelograms. Batik (1.7): Types "polyline" and "path" are stretched to parallelograms, but the type "line" stay rectangular. Inkscape (0.48): All types, "line", "polyline" and "path" stay rectangular. In the original group they are inside the silver rectangle, in the transformed group they exceed the silver rectangle. Corel Draw 12 (I know its old, from 2003), LibreOffice (5.2): The lines stay rectangular, the width is wrong. LibreOffice is the reason, why I ask for the correct rendering.
