I have build some extensions that generate guides (like guides in a grid with columns and gutters - available here: https://github.com/sambody/inkscape-guide-tools).

It works fine, but now that Inkscape 0.91 is out with the ability to change the color (and label) of an existing guide by hand, I had the following question: When I generate a guide in an extension, can I define the color (and label) of the guide when generating ? If yes, how?

I'm using a code like this : inkex.etree.SubElement(parent,'{ http://sodipodi.sourceforge.net/DTD/sodipodi-0.dtd%7Dguide ',{'position':position,'orientation':orientation})

I tried with just using 'color':'#ff0000ff' as extra parameter, but that didn't work.

If setting the color is possible, I could let the user choose a color for the generated guides, different from their default guide color.

Thanks.

Samuel

Hi Samuel, not at home to give exact code but color and label have a diferent namespace, you need xmlns:inkscape="http://www.inkscape.org/namespaces/inkscape" they are inkscape:color inkscape:label, similar to: {http://www.inkscape.org/namespaces/inkscape%7Dcolor {http://www.inkscape.org/namespaces/inkscape%7Dlabel Regards, Jabier.

New subject: generate guide with certain color in extension ?

if I manually edit the color of a guide using the gui, then I get something like below. You should be able to do the same by writing to 'inkscape:color'.

<sodipodi:guide position="100,548.57144" orientation="1,0" id="guide3336" inkscape:label="" inkscape:color="rgb(22,255,0)" />

AFAICT it won't help with current 0.91 even if the generated syntax is correct: Due to the partial implmentation Inkscape 0.91 and 0.91+devel will not render the guide with the color defined in the SVG source returned by the extension script.

Quick test: 1) open new doc 2) create a guide 3) assign a custom color to the guide 4) run any extension -> once the drawing content returned from the extension is reloaded in Inkscape's document window, the colored guide reverts to the original color.

I've tested the guide generation:

1. When using the extra parameter '{http://www.inkscape.org/namespaces/inkscape%7Dcolor%27:%22rgb(255,0,0)", as suggested by Jabier, it does write the color in the xml, as inkscape:color="rgb(255,0,0)"

2. And indeed, Inkscape does not pick up the color. (Even when closing and reopening the document.)

I'll wait for 0.92 to implement this then.

Thanks to all for all the feedback.

Probably not, because Inkscape does not read the color for the guides from the SVG source yet (the new feature was only partially implemented):

yes, you are correct: after saving the above file with a new color, when I reload it the changes are lost. The XML editor shows the new inkscape:color attribute but it is not used.
