Caputre DisplayObject as high res image for use with AlivePDF

[Richard Rodseth]

AlivePDF ooks like a noble effort. I'm trying to get higher resolution chart
shapshots into a PDF, and it appears that

1)  PNGEncoder can't handle transparency
2)  JPEGEncoder is very slow
3) These might be addressed in a forthcoming 0.1.5 release, but I'm not sure
how imminent that is.

There is an addImageStream method that takes a byte array. Can anyone point
me at a good example of capturing a DisplayObject as a higher-resolution
image?
