#4146: rgbcolor bug bites pdfs, casting to int solves it
----------------------+-----------------------------------------------------
Reporter: mhampton | Owner: was
Type: defect | Status: new
Priority: major | Milestone: sage-3.1.3
Component: graphics | Keywords: pdf, save, graphics, text, rgbcolor
----------------------+-----------------------------------------------------
Colored text breaks pdf saves. PNG saves and show() work fine.
It seems to be fixed by forcing the rgbcolor into ints, i.e. rgbcolor =
(int(1),int(0),int(0)) works fine.
Here's an example:
{{{
t1 = text('Hi, this is a bug',(1,1), rgbcolor = (1,0,0))
t1.save(DATA+'bugplot.pdf')
