Hi list,

I'm having a few problems with my WMS service using QGIS as client. May
be anyone has a few hints or ideas:

Using QGIS 0.8.0 on opensuse:

- a polygon layer doesn't show with transparency - even though it is
implemented in the WMS and it works with other clients, the transparency
as well is not adjustable using the properties menu (well i can change
it to 50% but it dioesn't change the view) - the transparency works very
nice, if I use the WMS-feeding postgis-service directly.
[projection on runtime is activated]

Using QGIS0.8.1preview2 (pretty fresh installation with complete
uninstall of 0.8.1p1) on WinXP:

- while zooming in a WMS-raster or vektor layer an error message appears:
msWMSLoadGetMapParams(): WMS server error. Image size out of range,
WIDTH and HEIGHT must be between 1 and 2048 pixels.

This is probably due to a bug in the QGIS program. Please report this error.

Tried URL:

- get FeatureInfo doesn't return any results using the WMS (works, if I
use the WMS-feeding postgis-service directly)
- projection on runtime is activated, but layers show up at different
places while loading the same layer via WMS and the WMS-feeding
postgis-service (the wms layer is displaced, it works using QGIS 0.8.0
on opensuse)

Any ideas, hints, solutions, explanations?



#1 Updated by Magnus Homann almost 16 years ago

  • Status changed from Open to In Progress

So, there are three issues:
1) Transparency doesn't seem to work.
2) Zooming doesn't work
3) Get featuerinfo does not work.

Am I right in this?

Can you split this bug in three parts, perhaps? It's easier to keep track on what is fixed and what is not. We work in small increments. :-)

I have (tried to) fix issue 2 (maybe wrong placement too?) in . Please download source, compile and see if it gets better. Many thanks for your help.

If you have svn, you can check out with

svn co https://svn.qgis.org/repos/qgis/tags/Release-0_8_0 qgis_08

and build with cmake.

Above comment was me, and the correct svn path is

svn co https://svn.qgis.org/repos/qgis/branches/Release-0_8_0 qgis_08

'branches' not 'tags'

#4 Updated by Magnus Homann almost 16 years ago

Regarding 1), transparency is not supported for WMS at the moment

Uninstall old versionj and install this and try. Most problems should be fixed.
