[Qgis-developer] Raster transparency not working?

[Alexander Bruy]

Hi again,

just tested with different datasets and seems this is not Raster transparency
plugin issue. I also can't add transparency for some datasets even using QGIS
Transparency tab.

Also there is another problem. If raster has float data type plugin
can't determine
which values exists in raster and which not, so it is a bit difficult
to setup transparency
for such rasters. Here is example: there are 14.55 and 14.736 values
in raster. If
we change transparency values with step 1.0 both values will be non transparent,
If step is 0.001, all values will be transparent but also many non
exsiting values
will be added to the transparency table.

And third problem is that transparency table in QGIS only allows 5
digits after decimal
separator. In most cases this is enough, but sometimes raster values
have more than
5 digits after decimal separator.
