Problems on installing under Windows 7/XP
|Assigned to:||-||% Done:||
I tested on Windows 7 and XP with Qgis 1.8.0, standalone and OSGeo4W installation.
OSGeo4W says shapely and geos have the needed version, and the standalone installer has them also in the appropriate subfolder (maybe from some other installation I did previously).
The plugin gets installed and loads without error, but remains greyed out in menu and Icons. Only way to get it working is to load raster and vector file, and then reinstalling the plugin. But next time I start qgis its greyed out again.
Using the plugin gives a strange result: only a layer with one single point named temporarily. tested with SRTM hgt raster and self-georeferenced geotiff.

From what you describe it seems there is nothing wrong with your installation. I designed the plugin in a way that it is only active when you have raster and lines layers loaded, otherwise it is useless to have it active, and that is why its greyed out.
So, if you load a raster layer and a lines layer into QGIS, the plugin's button becomes active.
It seems this is not very intuitive for new users. I am sorry about that.
I have provided a help page with a tutorial on how to use the plugin, but didn't remember to add some sort of menu entry for it, so it is only available when the plugin is active... not a very smart move i think.
Anyway, I am currently working on another plugin which will make profileFromLine unnecessary.
Currently profilefromline is currently performing two steps:
- create a point layer from a pre-existing lines layer
- sample raster layer(s) in the positions defined by the points layer
I think these two operations should be separate in order to better integrate into other workflows.

Just tested again, and got it running as you described, and found the help page.
But: Intervall is in layers units (that is WGS84 for a brandnew layer with me), and not project map units (Google mercator meters). So default intervall of 4 gives only one point at the start and end of the line. Choosing the raster changes absolutely nothing.
EDIT: Now I got it: Choosing a SRTM .hgt file, a column is added for the point layer with the hight at the point. This value can be labelled.
Perhaps you should give a small tutorial with examples pictures with your new plugin to come.
Thx for explaning.
