Public bug reported:

Hi,

I am using inkscape to create a SVG files containing multiple objects
and rsvg to then render these via cairo.

I am using rsvg_handle_get_dimensions_sub and position_sub() to read the
(x,y) and (w,h) for the objects which are then used to translate and
scale cairo before using rsvg_handle_render_cairo_sub() to render the
object.

I am running into anomalies when reading this attributes. I have
attached a stripped down source for a simple utility which 'walks' the
XML of the file and calls the two functions to dump out all the objects
in the file.

I have also attached a sample SVG file created with inkscape with a
single rectangle of 45x20px on a canvas of 100x100px

Running svgsize on this produces:

$ ./svgsize /tmp/inkscape.svg
svg : svg2 100x 100 ( 0, 0)
defs : defs4 0x 0 ( 0, 0)
namedview : base 0x 0 ( 0, 0)
grid : grid4469 0x 0 ( 0, 0)
metadata : metadata7 0x 0 ( 0, 0)
g : layer1 50x1047 ( 0,-1022)
rect : rect4471 50x1047 ( 0,-1022)

with scrambled sizes and positions for the rect.

If I load the file into karbon (the KDE editor) and save it (with no
other modifications), svgsize produces the correct numbers:

$ ./svgsize /tmp/karbon1.svg
g : layer1 45x 20 ( 5, 5)
rect : rect4471 45x 20 ( 5, 5)

Loading this back into Inkscape and saving it out again, and the
original values are shown.

I have tried this on inkscape stable 0.48 and the development 0.91

I am using rsvg 2.36.1-0ubuntu1 from precise. I get the same problem
with trusty.

Thanks,
