[from http://lists.osgeo.org/pipermail/qgis-user/2008-October/003515.html]

When loading raster layers from the file system in QGIS I can set a number
of very useful raster display options, such as transparency, band
re-ordering and remapping of raster values or cell ranges. This is all
very useful.

I wonder if there are any plans to add at least some of these options also
to WMS layers. At least a global transparency option or setting certain
rgb to values to transparent would be very useful, esp. if one wants to
combine various WMS layers from external resources.

Thank you for any information on the issue,

I meant to file a similar ticket as we had a request for WMS transparency on the qgis booth on INTERGEO.

  • Resolution set to fixed
  • Status changed from Open to Closed

We will have to see if this is acceptable, if not it can be disabled easily enough. It seems that if you apply the transparency (setAlphChannel) multiple times on the same QImage, the alpha values are added rather than set, at least on Ubuntu 8.10 (Qt 4.4.3) need to test on some other platforms. May consider opening this issue as another ticket.
