-----------------------------------------
You're right, I'll add a getter and setter and pass to PDFRenderer.
> PDFPrintable has subsampling but it can not be used

> Key: PDFBOX-4169
> URL: https://issues.apache.org/jira/browse/PDFBOX-4169
> Project: PDFBox
> Issue Type: Bug
> Components: Rendering
> Affects Versions: 2.0.9
> Reporter: Marek Pribula
> Priority: Minor
> Fix For: 2.0.10, 3.0.0 PDFBox
>
>
> We are happily using version 2.0.9 with subsampling. During that, I have
> noticed that memory consumption is unusually high during printing for a
> particular file. Decompressing and rendering this file was without issues (we
> have created an instance of PDFRenderer and set subsampling to true). During
> debugging I notice that in the PDFPrintable when calling
> renderer.renderPageToGraphics the renderer has this feature turned off. The
> reason is very simple. PDFPrintable creates its own PDFRenderer in the
> constructor and does not set subsampling on / does not allow this feature to
> be set from outside. I did some test with a modified version of PDFPrintable
> (setting always subsampling to true in the very same constructor the renderer
> is instantiated) and it shows significantly better results for memory
> consumption - in my case it was from OutOfMemory with Xmx1g to no problem
> with Xmx420m (I did not bother to test with lower Xmx).
>
> I am not sure if this was the intention but I do not think so since there is
> at least one if asking about subsampling and with this configuration, it is
> pointless since it always will be false.
