[postgis-users] [Qgis-developer] Fwd: WKTRaster Plugin 0.1

[Maurício de Paulo]

As asked, I've added a simple screenshot of the plugin working on my blog.
It's a fast presentation for my Brazilian friends.

> That's why i was able to alter it on windows. I can test the plugin part. I

> QGIS is releasing a new version these weeks. I'm going to ask if is anyone

> What kind of demo do you need? I don't have a hosting for the plugin at the
> moment but I can produce some ubuntu's screenshots (or even a video).
> The plugin's fairly simple, though.
> For the next request (a tool to process the queries), QGIS does have a
> really nice tool called RT_Sql to execute PostGIS SQL queries.
> I don't really know if I should bring a new tool to the application doing
> almost the same thing with just different datasources.
> What can be done is to talk with the guys who developped RT_Sql and check
> if they don't want a little improvement to cope with raster layers too.

> Anyway, there is still a mystic point for me: some processing returns
> vector and some return rasters (and I don'nt think that's all). That's...
> odd to cope with. I'm still giving some thought to it. I still need to read
> how postgis raster processing works and gives results.
