Hi, people!

I am using the latest Inkscape version in a Mac (PPC) and I get the following error message:

"The inkex.py module requires PyXML. Please download the latest version from http://pyxml.sourceforge.net/."

Is this something that we have to compile, or we just need to install it? I got to check it out... I didn't know Inkscape needed this, and probably a lot of guys out there feel the same about this... Maybe Inkscape should include all these dependencies, whenever it does not rely on the standard operating system configuration... Or, at least, there should be some advide in the website to download them together with the Inkscape binaries.

Are there any other requirements for good perspective effects other than '4 nodes' ? Maybe the problem is in python or that my Inkscape was compiled form sources?

Perspective bends the mind, not the objects on the canvas. I've also yet to get it working. :D

I agree that it's not clear up from the website. But I did find some instruction on the wiki here:

I'm running it on XP and on Linux and I didn't have a problem, but I know of others who have. It should be made more clear.

You don't have to compile them and if you downloaded the latest stable version of Inkscape for PPC, it has those python packages included in it (in the dmg you have the Inkscape application that you need to drag to Applications and two other folders that you need to drag to the corresponding python folder. All this should be made quite self-explanatory by the background image).

Hi, JiHO!

It seems that someone has forgotten to include the python files. The background image does show an arrow with the word "Python", but there is no alias, nor files, nor folders. Just the Inkscape itself and an alias to the Applications folder.

Hu? I have everything here. It is only in the PPC version, maybe you downloaded the universal one?

I am using the universal version. That's the default file, when we go to inkscape.org and click the download link :)

What (or who) is a PPC? I run on Slackware 11 Linux. I had enough trouble chasing down a version of Gnome that would work.

I'll wait until there is a version for Linux that has all this python/xml stuff included. Is there an ETA for this?

PPC is PowerPC, the processor in the Macintosh prior to Intel. I run Ubuntu Linux and I believe the standard install of Inkscape (plus maybe the python package installed in ubuntu by default) had everything I needed. I didn't have to install or compile anything to get the effect to work.

Thank you very much! I have just installed Inkscape_Python_Packages.PPC.dmg and now it worked fine.

Glad to know it solves the problem.

However, I still get an error message:

...

This is "normal", though unwanted indeed. The locale warning is present every time you start Inkscape. You just don't see it because you don't start it from a terminal. The second warning is because python script take the full document, do their things and give it back to Inkscape but do not specify the extension so Inkscape has to suppose it's SVG.

By the way, I have another question.

I use Portuguese locale in my Mac, but Inkscape ignores that setting and keeps running in English all the time. I know that Inkscape is available in Portuguese, at least in the Windows version. Does anyone know if it is possible to make it use the Portuguese localization?

Argh, it seems we can't get rid of this problem. It should work automatically. This locale warning is probably related, now that I think of it. What version exactly are you using (stable or development, universal or ppc only etc.)?

That's strange. Localization works for me in French, German, Spanish (with some problems with bold text though) but not Portuguese. The Portuguese locale file (I assume it's the one in the "pt" directory) is smaller than the others... strange.

Just watched the Heathenx's perspective screencast, neat.

Just throwing this on to the list:

To use the perspective effect in linux you need to have the numpy and linalg python modules installed. The easiest way to do this, in Ubuntu at least, seems to be to install the scipy module (not the numpy module). This is the ubuntu package called 'python-scipy' and can be installed with the package manager or from the command line by entering:

sudo apt-get install python-scipy

Hope that helps someone.

Cheers -Terry

(in case telling you you need numpy and then telling you not to install it doesn't make sense: scipy includes both numpy and linalg, whereas numpy doesn't include linalg, and you can't install scipy and numpy).

Nahhh.. go right ahead heathenx. Can you pay my monthly mortgage while your at it? ;)

Ha. Sure. Mortgage on a pop tent can't be too expensive...shoot, I'll just pay it off for you. Wiring the money now. Sending a little extra for a new lawn chair.

Feature idea.

I have no idea how hard this would be to implement, or even if it is possible. But it would be an interesting effect.

In Blender, you can take a mesh and add what is called a "lattice" modifier to it. The mesh is usually fairly complex from a face count standpoint. The lattice is usally simpler. It is just a "box" that surrounds the mesh with a few subdivisions.

What is neat is, that if you grab one of the verts in the lattice and move it, it acts like a sort of "bezier" control handle for multiple verts in the mesh, so by moving one vert in the lattice, you can deform a more complex mesh in a controlled fashion.

Could this sort of an idea be adapted to Inkscape? Say you have some text, you convert it to a path, maybe add some nodes. Then you surround it with a box that has a user definable number of nodes per side. If you grab one of those nodes, and drag it, it reacts with a certain number of nodes in the text path, dragging them like a magnet.

With something like this, you could flex and bend an object however you wanted.

Node sculpting kind of does that, yes, but it isn't quite the same.

Here is a link to the Blender wiki to give some idea of what I am talking about. Admittedly, this is 3D, but it has the gist of the idea.

http://en.wikibooks.org/wiki/Blender_3D:_Noob_to_Pro/Basic_Animation/Lattice

And a somewhat older link

http://www.blender.org/documentation/htmlI/x10279.html

As you perhaps can see, the whole model is selected. I am guessing that each node in the lattice has a certain "sphere of influence" and whatever mesh vertices that are inside a given sphere are affected proportionally.

The node

sculptinghttp://tavmjong.free.fr/INKSCAPE/MANUAL/html/Paths-Editing.html#Paths-Node-Sculptingfeature

of the node tool in the current release of Inkscape kind of does this. Although it's probably a little more detailed in it's operation than what you're after.

If I follow you correctly, this could indeed be very useful, not for a single path "node sculpting" but rather for multiple selections/groups of paths. For instance, in the example you gave, suppose you have a text line composed of several characters each a path and grouped together, if a "latice-like" tool was available in Inkscape, then you could simply put a box around the group of objects and select the number of nodes for that bounding box, then simply use "node sculpting" in the bounding box to the effect that the individual nodes of the actual paths to be modified accordingly, that would be one heck of a way to get for instance wavy text without resorting to text-on-path (creating first the wave path, then make the text follow such path), though text-on-path for this particular application is a better solution, for multiple path editing is not, suppose that the before mentioned text were characters of different sizes and shapes (different "font faces") then a tool like this would be very useful. It would be like "mass node sculpting". I think it would actually be very nice, IMO.
