doing my first steps in cpp (starting off with a tmsrasterprovider), I
thought to zoom to a certain scale first (so I do not need to scale the
But HOW is this done?
There is no 'zoomToScale' or 'zoomToMupp' or so.
And trying (using python console) to resize the mapcanvas first to
512x512 and then zoom to a calculated bounding box of 512*XXX (where XXX
is the wanted mupp) gives a zoomin/out action, but asking for the
mapUnitsPerPixel after that does NOT give me XXX? Any thoughts about that?
Another question: in the python console if I do a scale(1), why is the
map zooming in and out? Shouldn't the bbox stay the same with a 1?
Looking at the qgsrasterlayer and it seems pretty hard bound to the
wmsrasterprovider. Am I right?
