Hello, World!

I'm trying to make an extension that will create some shapes and paths and arrange them in specific order. All objects have dimensions specified in millimeters.
Creating square, for example, in millimeters is no problem just by adding + 'mm' to it's parameters. However this trick is not working with paths and translate attribute.
I'm sorry for maybe a silly question, but I'm not an experienced programmer, and any examples will be really helpful

Hi coper,

I'd suggest you take a look at a couple of other extensions first, and also at the 'simpletransform' and 'simplepath' python modules that come with Inkscape, to find out how to do it. You don't need to reinvent everything from scratch, just take some time to investigate. Select an extension that does something similar like the one you want to write and start from there.

For unit conversion, you could also use the built-in one (something like self.unittouu and the other way around). You can find that used in many of the extensions that Inkscape ships with, and the method lives in inkex.py.

In Inkscape you can set default units per document, I expect transforms and other relevant operations would follow that setting, although I haven't checked. There is probably a guideline in Inkscape programming how to handle units.

You'll probably get an answer here, but just in case you don't try emailing the dev mailing list, or asking in #inkscape-devel room on IRC.
