cairoQPaintDevice
library for Qt: QPaintDevice implementation that uses Cairo Graphics Library as a backend (e.g. for high-quality PDF/EPS/PNG/SVG output!). This library works and was tested with Qt >=4.7, but possibly works with all versions since Qt 4.0!

Usage
Using this project is simple:
- compile the four project-files into your project:
SOURCES += qcairopaintdevice.cpp
qcairopaintengine.cpp
HEADERS += qcairopaintdevice.h
qcairopaintengine.h
2. link your project agains cairo:qmake
INCLUDEPATH += cairo pixman-1
LIBS += -lcairo -lpixman-1 -lz -lpng
win32:LIBS += -lgdi32
3. use the newly available QPaintDevice:c++
// include cairoQPaintDevice header
#include "qcairopaintdevice.h"
// ...
// create paint device to draw to test.pdf, 200x100mm QCairoPaintDevice * cairoPDF=new QCairoPaintDevice(QSize(200,100), "test.pdf", QCairoPaintDevice::cftPDF);
// paint onto paint device { QPainter p; if (p.begin(cairoPDF)) { paint(p); } p.end(); }
// delete paint device and close/finalize file. delete cairoPDF; ```
