gimp-poppler version 0.4.0 has been released. It can be downloaded at

There are other features; check the NEWS file for details.
Wow, good work, that's really nice. Ideally, you shouldn't have to use
the /usr/include/popper/* API, so I was looking through glib_glue.cc to
see what kind of functionality we need to provide in the glib wrapper to
avoid this. First, the page label is actually available in the glib
wrapper - it's probably not the most discoverable interface, but it's a
GObject property. So you can do
char *label = NULL;
g_object_get (G_OBJECT (poppler_page),
"label", &label,
NULL);
to get the label for a PopplerPage.
Yes, this was discovered by one of the gimp developers literally
minutes after I made the 0.4.0 release. It's generally considered
good style for gobjects to provide a C accessor function for each
property, and vica-versa, for exactly this reason.
> As for the anti-alias toggle... I'm not sure. It's only affecting the
fonts with the splash backend, right? And the cairo backend can't
respect that setting. Is it really something you'd want to disable?
Generally, the ability to turn off antialiasing is not necessary or
desirable, but there are certainly image-manipulation situations where
having crisp, full-intensity borders is more important than subpixel
accuracy. This is why pretty much every operation in GIMP can have
the antialiasing turned off. It would be a shame if the poppler
plugin couldn't do this, when the old ghostscript-based plugin could.
Getting at the paths and text in the PDF as you mention in your previous
mail is a lot more difficult. We can't easily get at that with the
current poppler structure, and defining a good API for this isn't easy
either.
We'll see what we can come up with.
Anyway, it's great to see poppler and the glib wrapper used outside
evince. Let us know if there is more information you need from the
poppler-glib API.
We'll stay in touch.
