[Qgis-developer] Re: Colormap

[sergio cavalcante]

Hey guys,

I've solved the problem.

It was just use the function :


mRasterLayer->setRasterShaderFunction(myRasterShaderFunction);

at the end of the applypalette() , and and create the myRasterShaderFunction
this way:

 QgsColorRampShader* myRasterShaderFunction = new QgsColorRampShader(0,255);

instead of this way:

QgsRasterLayer * mypLayer = new
 QgsRasterLayer(myRasterFileInfo.filePath(),myRasterFileInfo.
completeBaseName());
