> This is an alternative to the PDFBOX-1850 patch to speed up TestImageIOUtils.
> Rather than using multi-threading, this patch reduces the scope of the
> TestImageIOUtils test. The purpose of TestImageIOUtils is to check
> thatImageIOUtils can write jpeg, bmp and wbmp files without throwing an
> exception. Looking at the mailing list archive
> http://mail-archives.apache.org/mod_mbox/pdfbox-commits/201112.mbox/%3c20111218154622.3ee762388...@eris.apache.org%3E
> we can see that the original issue was that the JPEG compression
> configuration broke BMP writing. It is therefore sufficient to convert only a
> single PDF file to each of the output formats in order to test this.
> The test is not quite so simple though, as TestImageIOUtils is also used for
> processing embedded images in PDF files and so needs to be tested on
> appropriate PDF files, this is not something that the current test suite was
> actually doing. I've therefore added some test PDF files containing PNGs,
> JPEGs, and pixmaps. These are from libharu https://github.com/libharu/libharu
> and are under the ZLIB/LIBPNG license.
> Because TestImageIOUtils now only needs to be run on three files it takes
> around 2sec on my machine rather than over 30sec.
