>             Project: PDFBox
>          Issue Type: Bug
>          Components: Rendering
>    Affects Versions: 2.0.5
>         Environment: Windows
>            Reporter: Esteban Nicolas Ruiz

> Attached pdf files take too long (more then 20 secs) to render in PDFDebugger (they are a simplified version of a real life example that I can not publish for privacy reasons).
> Displaying more shades seems to increase complexity exponentially: all the attached files contain the same shades but each one display a different range of them. 
> These are the rendering times as displayed in the status area of PDFDebugger for each of the attached files:
> 0to25.pdf: 22.095 seconds
> 25to50.pdf: 33.726 seconds
> 0to50.pdf: 67.481 seconds
