This is a read-only archive of the inkscapeforum.com site. You can search for info here or post new questions and comments at I use inkscape Inkscape 0.48.2 r9819 (Jul 11 2011) on Ubuntu 11.10 (64bit).
My goal is to get the horizontal, vertical position and height and width of all objects in my inkscape file.
I want to extract this information on the command line.
As instructed on the man page, I use the command line option, and I do not want to use the GUI (so I use -z)
It works, but I do not get the answers in pixels, instead it is another unit (not sure which, maybe millimeters).
For example:
If I use
inkscape -z -S myfile.svg
I get:
svg2,83.785713,68.071414,112.42857,102.42858
layer1,83.785713,68.071414,112.42857,102.42858
stimulus1,83.785713,68.071414,36.714287,36.714287
stimulus2,159.5,133.78571,36.714287,36.714287
this is a comma separated list, a line for each object. All fine, just not in pixels as unit.
Is there a way to get this done. I have tried setting the default units to px in my document settings.
Thanks for any help.

Re: getting height and width of inkscape objects on commandl
dunno
I would try a very simple object with a know value,1 x 1 box ? and then see if I could interpolate the units that inkscape is using
I think some question about scaling in inkscape came up a while back and I believe the internal units are in pixels?
be sure to post back what you find out

The results are in pixels (aka SVG user units).psytoolkit wrote:It works, but I do not get the answers in pixels, instead it is another unit (not sure which, maybe millimeters).
Could you explain how you verify the results and conclude that the units in your test case are not pixels (aka SVG units)?
(Note that the returned x and y coordinates are relative to the SVG coordinate system (which differs from the rulers as seen in the GUI): the SVG coordinate system has the origin in the upper left corner of the page, with the y-axis pointing down, whereas in Inskcape's GUI, the origin is in the lower left corner of the page, with the y-axis pointing upwards.)

Thanks to all for the quick replies 
. You are right, the units are in pixels. And you are right that
the coordinate system of the GUI and the "inkscape -S"-coordinate system have different
origins.
I am still trying to figure out 2 things:
1) Can we get "query" the document size in pixels?
2) What is the object ID "svg2" exactly (which is created in any new document).
