Re: [Qgis-user] RE: random crashes during editing
Hello, In case it may help: I also have had a lot of crashes of qgis also, recently. At first, it seemed to happen when I was resizing the main window. I changed my windows manager (icewm on debian squeeze, switched to kde), it didn't help. In fact, it was happening quite regularly, after a few minutes without using qgis, even when I was not resizing the window, but when I was zooming or panning. I noticed that the autosave extension was always generating empty files instead of backups of the .qgs. So I got rid of this extension: and now, no more crashes (so far...). So maybe was it related to the autosave extension? I'm on a "report-rush" period, so it is not the very right time to play with this. Later on, I'll try this extension again. It was strange, because qgis used to be extremely stable and robust, and all of a sudden, a few weeks ago, it seeemed very unstable, capricious. I almost felt like I was on a windows machine! Scary, isn't it?... A+ Pierre Michael Diener claviota: Hi, I teach an introduction to GIS using qgis and we had random crashes, Osgeo4w installer problems. Very hard to trace the cause since the students could not replicate the issues or properly describe what went wrong.

[Qgis-user] Which ONE image in a .vrt is currently being displayed
With GDAL 1.7.2, released 2010/04/23, I used gdalbuildvrt to build a .vrt file that points to 726 GeoTIFF images. Then, I use QGIS 1.5.0, release 13519M to pan and zoom through these images. When zoomed in, how do I get Qgis to identify which ONE of the raster images is currently being displayed?

[Qgis-user] Grayscale GeoTiff and transparency using GDAL.
Hi all,
I'm writing a plugin using GDAL C library to allow the user to create a
grayscale GeoTiff with transparency.
I've used the following code to init the raster:
Driver = GDALGetDriverByName("GTiff");
papszOptions = CSLSetNameValue(papszOptions, "COMPRESS", "LZW");
Dataset = GDALCreate(Driver, SrcFilename, XSize, YSize, 2, GDT_Byte,
papszOptions);
Band1 = GDALGetRasterBand(Dataset, 1);
GDALSetRasterColorInterpretation(Band1, GCI_GrayIndex);
Band2 = GDALGetRasterBand(Dataset, 2);
GDALSetRasterColorInterpretation(Band2, GCI_AlphaBand);
...
Init the two bands
...
The result is a correct grayscale image but without transparency.
Can someone point me a way to create a grayscale GeoTiff with a
transparency?
Thank you very much.
Pietro

Re: [Qgis-user] QGIS "Near"
No plugin that I know of, but it could probably be done quite easily from the Python console, something to the tune of (untested!): layer = qgis.utils.iface.mapCanvas().layer(0) provider = layer.dataProvider() provider.select([]) feat = QgsFeature() index = QgsSpatialIndex() while provider.nextFeature(feat): index.insertFeature(feat) provider.select([]) while provider.nextFeature(feat): near = index.nearestNeighbour(feat.geometry().asPoint(),1) nearest = near[0] # now do something here with the two points... and output results as you like # Obviously you'd have a bit more work to do here to compute angles etc. but all this functionality is available via the QGIS API... # If I get a chance, I might try to add this to the fTools/Vector menu...
