-----------------------------------------------------------
I know PDFs are not well formed.
My point was that an exception will not help, on the contrary, parsing will
fail, would it not?
If it was a sensible default or any other idea in the direction of accepting
the malformed PDF and displaying the closest image we can get, I would have
understood.
But this code says "if infinite, then throw", so I am not sure how that helps

> Key: PDFBOX-4877
> URL: https://issues.apache.org/jira/browse/PDFBOX-4877
> Project: PDFBox
> Issue Type: Improvement
> Components: Parsing, Text extraction
> Affects Versions: 2.0.20, 3.0.0 PDFBox
> Reporter: Alfred
> Assignee: Andreas Lehmkühler
> Priority: Major
> Labels: Optimization
> Attachments: PDFBOX-4877.patch
>
> Original Estimate: 1m
> Remaining Estimate: 1m
>
> I am testing text extraction from PDF and profiling the execution.
> I found that the third major time consumer is with matrix multiplicaitons.
> The Matrix class spends large amounts of time copying results to new
> instances.
> Also, the if statements are slowing down execution as they kill performance
> in modern CPUs.
