PDFBOX-3484: cache PDImageXObject if resources are not needed
> Implement some caching of PDImageXObject
> ----------------------------------------
>
> Key: PDFBOX-3484
> URL: https://issues.apache.org/jira/browse/PDFBOX-3484
> Project: PDFBox
> Issue Type: Improvement
> Components: Rendering
> Affects Versions: 2.0.2, 2.0.3, 2.1.0
> Reporter: Tilman Hausherr
> Fix For: 2.0.3, 2.1.0
>
>
> Markus Barbey mentioned on the mailing list that
> {{PageDrawer.drawImage(PDImage)}} has a new instance every time, because the
> caching in PDResources is disabled, so the caching of the BufferedImage is
> useless.
> It is indeed disabled, see near the bottom of PDFBOX-2370.
> I'll enable it for cases where PDImageXObject does not need anything from the
> resources. An image could be in several pages with the same colorspace name,
> but that name could be something different in different pages. (very
> unlikeky, but possible!)
