Re: [Qgis-developer] QGIS custom widgets with python plugins

I'm getting this erros with several plugins (processing, qgis2leaf, ...) after update with today's master on Linux: Couldn't load plugin 'processing' from ['/usr/share/qgis/python', '/home/pedro/.qgis2/python', '/home/pedro/.qgis2/python/plugins', '/usr/share/qgis/python/plugins', '/usr/local/lib/

Re: [Qgis-developer] QGIS 2.6 compilation on Windows

Hi Martin, I think I ran into this recently. There was a commit in 2.6 [0] that apparently requires a newer version of flex or bison (bison 3.x, I think?) than is available with the GnuWin32 project as noted in INSTALL [1]. Instead I used the precompiled binaries available from the 'Win flex-bison

[Qgis-developer] Viewport rotation

Hi all, I'm looking at implementing viewport rotation support and wondering if anyone has already an idea about what it would take. Could adding support in QgsMapToPixel be possibly enough to make navigation tools aware of rotation ? Or would it be better to plug another transformation in between,

[Qgis-developer] Plugin versioning and priority

Hi all, a number of users are having problems with older version of a plugin in their home dir (this happens especially often with Processing) masking the system one. IMHO the behaiviour is correct, but the user should be warned (e.g. "You are using an older version of a plugin, a new one is avai

[Qgis-developer] OGR VRT and SrcSQL

I am working with OGR VRT files in QGIS. When I use the "SrcLayer" tag, all works correctly. But when I use "SrcSQL" tag, QGIS seems to load the file correctly, but nothing appears in the canvas. exemple: test.shp SELECT * FROM test all attributes are correctly di

Re: [Qgis-developer] Processing with raster files > 4GB

Hi, I was able to do my color replacements with gdal_calc.py. It works fast and efficient. Here is my syntax: gdal_calc.py -A image.tif --outfile=image_output.tif --calc="(A==249)*255+(A!=249)*A" Syntax looks similar to the QGIS raster calculator - but as opposed to the QGIS raster calcul

Re: [Qgis-developer] Processing with raster files > 4GB

Nice to know that gdal_calc works fine ;) I work a lot with gdal + numpy, even for custom tools, and I admit they work very well together! 2014-11-19 11:41 GMT+01:00 Andreas Neumann : > Hi, > > I will have to do further testing about GRASS. On Windows (OSGeo4W > install) it does not work too we

Hi, I will have to do further testing about GRASS. On Windows (OSGeo4W install) it does not work too well. It probably works better on Linux. The gdal_calc.py solution works very fast though - glad that we came to this solution! Andreas On 19.11.2014 11:25, G. Allegri wrote: And do you ha

Re: [Qgis-developer] Processing with raster files > 4GB

And do you have problems with GRASS (directly, not through Processing)? In GRASS7 you can even drectly write to Geotiff without passing through the internal format (http://grass.osgeo.org/grass70/manuals/r.external.out.html ). If GDAL is built with bigtiff support there souldn't be problems... gio

Hi Andreas, Yes, you can use gdal_calc.py Certainly you need to perform several processes, but are very fast! Be careful with bands! Perhaps you will want to separate them. Ciao, * * *Carlos López Quintanilla* www.psig.es carlos.lo...@psig.es +34 699.680.261 2014-11-1

Re: [Qgis-developer] Processing with raster files > 4GB

Hi Andreas, you can surely try to import the raster directly into GRASS in a 64bit linux, very often this overcome memory issues, and use mapcalc sintiax, something like: reclassed_raster = if(original_raster == 249,255,original_raster) regards, Roy. GDAL would be my first choice - becaus

Hi Carlos, GDAL would be my first choice - because it easy to automate. However, I don't know how can do my task with GDAL. From my grayscale tiff images I want to replace one pixel value (249) with white (255). All other pixels should stay at the value they have. I came across https://gith

Hi, I tried various tools, e.g. * SAGA reclassify * GRASS r.mapcalc Both work fine on smaller data sets, but fail on big data sets. This is on Win7 64bit, with the OSGeo4W installer. I have 8gb RAM and 40GB disk free on C:, more free space on other disks where the data resides. I am not to
