[Qgis-user] Blending layers question

[Nicolas Cadieux]

Hi, 
In your raster properties, you can render layers using various methods like add, multiply...  It works very well.  Same options are available for vector layer and objects.

	Hi Group, this is possibly one of those questions about a question. I'd like to create some blended layers that look the same as layers in QGIS with transparency applied. I've another application that my data lives in and they supply a calculator that's able to do some fairly reasonable maths on different grids and other types of data. How does QGIS do transparency, and can I use those equations / method elsewhere. Thanks Matt
