C++ PDF to Image

[xmarat]

Ищу библиотеку для конвертирования pdf в рисунок. Вроде с помощью libcairo можно сделать, но внятных примеров так и не нашел. Кто нибудь решал данную задачу? Может посоветуете библиотеку? Заранее благодарен.

[hippi90]

libpoppler смотрели?

[xmarat]

Нашел такой пример http://yassernour.wordpress.com/2010/04/04/how-hard-to-build-a-pdf-viewer/

Компилирую так:

Код: [Выделить]

gcc `pkg-config --cflags gtk+-2.0 poppler-glib`  `pkg-config --libs gtk+-2.0 `  testpdf.c   -o testpdf

Выдает следующие ошибки:

Что я делаю не так?

[RazrFalcon]

залинковали не верно

[xmarat]

Если делать по примеру, т.е.

Код: [Выделить]

gcc -o testpdf testpdf.c `pkg-config –libs –cflags gtk+-2.0 poppler-glib`

то выдает ошибку:

Код: [Выделить]

testpdf.c:38:21: фатальная ошибка: gtk/gtk.h: Нет такого файла или каталога
компиляция прервана.

а как правильно залинковать?

[hippi90]

Установить пакет libgtk2.0-dev.

[xmarat]

уже установлен.

[arrecck]

pkg-config –libs –cflags gtk+-2.0

pkg-config --libs --cflags gtk+-2.0

[xmarat]

pkg-config --libs --cflags gtk+-2.0

Выдало:

Код: [Выделить]

testpdf.c: В функции «MessageBox»:
testpdf.c:111:1: предупреждение: формат не является строковой константой, и не заданы аргументы форматирования [-Wformat-security]

Разбираюсь дальше...

[xmarat]

А возможно ли использование poppler без glib, qt, и т.д.? Т.к. мне достаточно рендерить документ в cairo_t.
