[poppler] utils/pdftohtml: image creation not working?

[Warren Toomey]

Hi, I'm trying to use (and make changes/improvements to) utils/pdftohtml.cc.
The program should be able to extract DCTStream-type images from PDF files,
but for some reason the functions HtmlOutputDev::drawImageMask() and
HtmlOutputDev::drawImage() in HtmlOutputDev.cc are not being called. Even
putting a printf() and exit(0) at the top of both functions does nothing.

An earlier verison of pdftohtml (0.39) which used xpdf has the same functions
and they are being called correctly. I'm a C programmer, not a C++ programmer,
so I can't work out what is missing/broken to cause the current behaviour.
If someone could give some suggestions as to what to look at, I'll try to
fix the problem.

Many thanks for any ideas,
	Warren
