Answer 1

You can get the code for this from Tim Sutton Tutorials.

What you are looking for is a combination of the two tutorials

• Adding Raster to QGIS (source here)
• Working with Vector Attributes (source here)

These are all C++ code. If you need python code. see here. But python tutorials are not exact port of C++ code. But Many Thanks to Tim.

Hope that helps
