in my application I use OGC:CRS83 for the coordinatereferencesystem, but now I had to change it to EPSG:3395 when I call :
mQgsCoordinate->createFromOgcWmsCrs("EPSG:3395") there is nothing in the mapcanvas. If I put back OGC:CRS83 my map was displayed Any idea ? My code is :
mQgsCoordinate->createFromOgcWmsCrs("EPSG:3395"); qDebug() isValid()) qDebug() coordinateTransform(); myRender->setExtent(extent()); myRender->updateScale(); Do I forget a step for the EPSG:3395 ?
