Hi,
Thanks a lot! I think it would be a great help to me. I'm only using
poppler-qt4 binding for my application now. So, I guess, I would have to use
both Qt4 and cpp/glib bindings in my application, right?

Subject:Re: [poppler] Vertical or horizontal writing?
Hi,
Yet I'm not sure how you use poppler in your application,
but GfxFont class has a method to obtain "writing mode"
in PDF terminology. Please see GfxFont.h, you can find:
/* this is default */
106 class GfxFont {
107 public:
108
...
206 // Return the writing mode (0=horizontal, 1=vertical).
207 virtual int getWMode() { return 0; }
/* this is for CID-keyed font */
321 class GfxCIDFont: public GfxFont {
322 public:
...
333 // Return the writing mode (0=horizontal, 1=vertical).
334 virtual int getWMode();
And, you can find how poppler identify the writing mode
in GfxFont.cc:
1763 int GfxCIDFont::getWMode() {
1764 return cMap ? cMap->getWMode() : 0;
1765 }
Is this what you want?
