[jira] [Commented] (TIKA-2620) Set sys property to get better rendering speed by default

Luis Filipe Nassif commented on TIKA-2620:
------------------------------------------

Hi [~tilman]. When printing PDFs to images before OCR, our default is to use 300dpi. If the image is bigger than that, it will be scaled down at the end. Reading PDFBOX-4137, I understood images will be subsampled before being decoded and not when rendering, possibly saving lots of memory, or am I wrong?

Thanks

> After upgrading to PDFBox 2.0.9, we now get a logged warning:
> {noformat}
> INFO  To get higher rendering speed on JDK8 or later,
> INFO    use the option -Dsun.java2d.cmm=sun.java2d.cmm.kcms.KcmsServiceProvider
> INFO    or call System.setProperty("sun.java2d.cmm", "sun.java2d.cmm.kcms.KcmsServiceProvider")
> {noformat}
> Unless there are objections, I'll add a static call to the PDFParser to {{System.setProperty...}}.
