Inkscape users,
I have an Inkscape file that is about 4.5 megabytes in size. It is essentially an A4 size comic book page.
One layer contains the orginal scanned pencils, which were in PNG format. The next layer are flat colours, no gradients, just simple paths with colour fills.
The top layer is the inks, which were almost all created with the calligraphy pen. This seems to be where the problem is. Even just locking/unlocking the layer causes Inkscape to pause for many seconds, maybe 10 or so.
My computer is by no means the latest, but it should handle these file sizes alright. I use GIMP and Photoshop on larger file sizes without any noticeable slowdown. (My computer is a 2.8GHz dual processor, with 2 GB RAM, running Ubuntu 9.04).
Is it normal for a collection of paths created with the calligraphy pen to be this bulky and slow a system down?
I tried removing the original scan images to try and reduce the file size, but it has not helped.
Is there something I'm doing inefficiently or wrong, or is it just that complicated paths can't help but soak up lots of memory.
Any advice would be much appreciated.

I have long moaned that "Nodes mean slow" :( I have a fast machine and 2gigs of RAM. It makes no difference. I think it's all the looping through those long lists of nodes....
You are doomed. Unless you can simplify or chop-up your comic page into frames and assemble them later in Gimp.

Donn,
Thank you for responding.

Okay. While it's a little disappointing that there isn't a way to optimize the file for better performance, it's good to know that at least I'm not doing something wrong.
I'll export the paths into a PNG and handle the colouring in Photoshop or GIMP. It means committing to rasterizing the images sooner in my process than I had hoped, but hey, life is full of compromises.
And please be sure to file a bug/feature request at http://bugs.launchpad.net/inkscape/
In the end there will obviously always be cases where Inkscape is too slow, but Inkscape could most definitely be faster in some cases. And just locking/unlocking the layer should (from an intuitive standpoint) NOT cause such a big pause.

Hey,
I'd like to write a Python script in Inkscape, but I cannot find something like a straightforward "API" or something. I have seriously Googled quite a bit on it, but everything looks horribly complicated. Is there a straightforward way for creating a line from A to B, for example? Or does everything I want to do in Python require some complicated XML handling?
Thanks,
Maarten

All interaction with the svg involves the XML representation. In you example, to create a new line you would add a bezzier curve objext into the DOM. (I think that is the right term). Fortunately, the xml handling code is available in python. Check out existind scripts for examples.

A number of people have proposed building a drawing API on top of the current xml handling base, but no one has followed through. You might be able to save some effort if you merge with svg-utils:

I'm still wishing for a model by which we have access to the living inkscape internals and access to draw with all of those tools in python.

Hey everybdoy,
Thanks for your replies.
So, basically, if I'd want to get information from the underlaying drawing (like the coordinates of a node), I'd have to do XML operations? Like finding an attribute and it's value, etc?
I'll have a look!

Yes, that was what I was hoping for. A bit like in Blender, maybe. Programmig in Python there is surprisingly straight-forward, compared to its´ user-interface :) I guess people would create a lot more "effects" if there was a simple and straightforward way of saying things like:
x=selection.drawingNode[3].x
or
myBezier.addDrawingNode(myNewNode)
Kind regards,
Maarten

Keep going! It would be very helpful to your cause if you could start a page on the Wiki to design the API you seek. Implementation is probably pretty easy here, I think it is the API design part that is holding people back.

For a node, yes.
Some python extensions actually call another instance of inkscape on the current file, using the --query-all flag which makes inkscape dump id,x,y,w,h (i.e. bounding box) for all objects, something you can't really do just parsing the XML, on account of possible layered transformations.

Hi,
Thanks for the links. That looks very good... Something like that, indeed, but then straight from Inkscape.

Hey everybody,
ClarisWorks etc...: The meaning of life IS Inkscape, isn't it...? ^^
But seriously, elaborating on my previous question (about the creation of an API for creating "artistic" python scripts), wouldn´t it be handy to have a "build in" script editor? Or is that already present and haven't I been able to locate it in Inkscape? Again, I'm thinking of the way one creates VBA applications in Word... These things would lower the barriers for users to quickly create some scripts, which would result in a more available effects on the internet as well.
Regards,
Maarten
