Alfred commented on PDFBOX-4875:
--------------------------------

I don't want to annoy you guys insisting.
I understand pdfbox for android is a different project.

The memory savings are probably still important even we we're not targetting 
devices..
I saw 3 memory related bugs only in the past 2 days: PDFBOX-4690, PDFBOX-4718, 
PDFBOX-4862
If we can save some memory by only loading the fonts that are actually 
required, it will help a bit.

A bit here, a bit there, it adds up ...

> Lazy load standard 14 fonts, only if needed

>             Project: PDFBox
>          Issue Type: Improvement
>          Components: Parsing, Text extraction
>    Affects Versions: 2.0.20, 3.0.0 PDFBox
>            Reporter: Alfred
>            Priority: Major
>              Labels: Optimization

>   Original Estimate: 1m
>  Remaining Estimate: 1m

> I am testing text extraction from PDF and profiling the execution.
> I found that the second biggest time consumer is the static code in 
> Standard14Fonts that loads fonts from the pdf box jar.
> Looking at the code I realized we don't have to load all fonts statically, 
> when the class loads.
> Not all PDFs need all fonts, so, if we lazy loaded them, only when needed, it 
> will save some time and some memory.
> The memory part in particular would be important when running on a tablet or 
> a phone, where the entire memory space of the app is 80M - 160M.
