Convenience wrapper around Aggdraw for easy lightweight drawing

pyagg's Issues

Python 3 support

Just found this project and it looks very promising.

I am using the aggdraw module for one of my projects and I have fixed a couple bugs (path drawing) and added Python 3 support. You can find my version of aggdraw here.

I tried running a couple of your tests using python 3, but it looks like the code is still python 2 only (old style print statements, etc.). You might consider upgrading the code to be python-2 or 3 compatible. I found the modernize (aka python-modernize) package to be very useful for converting the files in my project, requiring only minimal fix ups afterwards. It uses the six module to achieve compatibility.

pip install failed on linux(ubuntu and centos)

I am trying to install on linux, but get an error:

It's not convenient for me to clone the repository and run setup.py, would be great if you can fix the pip problem, thanks in advance.

Linux Support?

Would it be easy to add Linux support?

I'm using this library to test PyCRS.

canvas_test.py: TypeError

micah@micah-VirtualBox:~/PyAgg-master$ python canvas_tester.py 
Traceback (most recent call last):
  File "canvas_tester.py", line 195, in <module>
    test_text()
  File "canvas_tester.py", line 36, in test_text
    canvas.draw_axis("x", 0, 140, 0, 25, ticklabeloptions={"textsize":30, "rotate":40, "anchor":"sw","fillcolor":"white"})
  File "/home/micah/PyAgg-master/pyagg/canvas.py", line 1178, in draw_axis
    for x in xpos:
TypeError: 'int' object is not iterable

This happens on Linux and Windows using Python 2.7.

Requires PIL/Pillow with FreeType enabled?

Stack overflow told me that PIL/Pillow requires FreeType to be enabled. The way to resolve this would be adding that this is required to the documentation.
