im using the linux version of inkscape .46, when i try to use perspective it says to use the subprocess module:



so how do i do that?

I am also getting this error.
I am using openSUSE 11.1 with KDE4.3Beta and Inkscape 0.46.
I have installed python-numpy 1.2.1-0.pm.1

I too have this error on Ubuntu 9.04 Jaunty Jackalope.

Hello,

I'm using Ubuntu 9.04 and Inkscape 0.46.

This problem I've too using perspective.py and summersnight.py.

Is there a solution?

I too receive the same warning message when applying the perspective effect. However, when I click the Ok box, the effect completes correctly.

Here are the steps I use to achieve a successful perspective transformation, using Ubuntu 9.04/Inkscape .46:

1. Use to create some text.
2. Convert the text to a path [Path>Object to Path(Shift+Ctrl+C)].
3. Starting with the bottom left corner, draw a box with the with exactly 4 nodes.
4. Select the text, press shift and select the box.
The order you select the text and the perspective box is important. Make sure you select the text first.
5. Then apply the perspective, Effects->Modify Path-> Perspective

The warning message box will pop up, press ok.


First post, hope this helps everybody.

The warning message is just that - warning, but not indicating a failure. You get these messages from Python 2.6 because the extension scripts included in 0.46 are somewhat dated and were written with older Python versions in mind. Windows and OS X users don't see them because their default Python version available in Inkscape is still 2.5.x.

Inkscape 0.47 will include updated versions of many scripts - including those that are known to cause these messages (Perspective, Envelope, Restack). For details see bug #387446 in Inkscape: “Extension deprecation warnings”.

bug still existing in version 0.47
