It's main use is to "code" svg images.

pysvg's Issues

pysvg.animate.set hides Python's set keyword

There's no way to access Python's set (or is there?) if your program begins as 
follows:

from pysvg.filter import *
from pysvg.gradient import *
from pysvg.linking import *
from pysvg.script import *
from pysvg.shape import *
from pysvg.structure import *
from pysvg.style import *
from pysvg.text import *
from pysvg.builders import *

The reason is that pysvg.animate.set hides Python's set keyword. Could PySVG 
rename this object to something else?

Turtle graphics not flexible enough about style

Style of the pen is set only once during initialization of the Turtle class. 
this keeps people from using the same instance when drawing different objects 
objects with different styles).

Instead of using several instances depending on the style the issue should be 
solved by storing the style information for each polyline seperately.

Add functionality for boundaries

Add methods to calculate (and draw) inner and outer boundaries (boxes) for 
elements.

examples: 
-draw the outer bounds of a circle as a dashed rectangle.
-draw the biggest rectangle that could be included in any ellipse.

Newlines inserted after XML opening tags alter content

What steps will reproduce the problem?
1. Create a text element with xml:space="preserve" attribute (used for 
preformatted monospace text labels).
2. Examine output XML and/or import SVG in eg Inkscape

Example code snippet:

label = text('Hello', 10, 10)
label.setAttribute('xml:space', 'preserve')
label.getXML()

What is the expected output? What do you see instead?

Expected XML is:

<text xml:space="preserve" y="10" x="10"  >Hello</text>\n

Actual XML is:

<text xml:space="preserve" y="10" x="10"  >
Hello</text>\n

The linebreak inserted after the opening text tag affects the displayed 
content. In Inkscape, for example, the label appears 6 characters long instead 
of the intended 5.

What version of the product are you using? On what operating system?

PySVG 0.2.1; Linux Mint

Please provide any additional information below.

Resolved by removing the \n from line 63 of src/pysvg/core.py. So, now the 
content of that line reads:

            xml+=' >'

rather than:

            xml+=' >\n'

problems with parsing and saving a file containing unicode and "&"

The patch below is a little hackish but it fixes problems with files containing 
non-ascii chars inside <text>/<tspan> elements

.attributes[ should be ._attributes[ in attributes.py

What steps will reproduce the problem?
1. image.get_xlink_href() on an image object

What is the expected output? What do you see instead?
AttributeError: image instance has no attribute 'attributes'

What version of the product are you using? On what operating system?
trunk, OS X with Python 2.7.2

Please provide any additional information below.
Several of the attribute classes are still using .attributes rather than 
._attributes. I've attached a patch that should fix the issue on trunk.
