Bruce, Hopefully you'll find help among the developers, this is really a critical missing utility in QGIS.

Agustin: I have not seen any of these errors in the Windows version of QGIS. It must be related to a difference between the two systems. I only have one Linux system and it is CENTOS and I haven't been able to build QGIS there yet. It may be possible to have an option to draw a circle (or perhaps cross-hairs) after the draw is done at the coordinates that are entered, I will check into this.

I've tested on ubuntu jaunty with unstable qgis 1.2.0: 1.Image clipping (should not be named raster clipping?): Once I click "Clip the Image": I get: An error has occured while executing Python code: Traceback (most recent call last):File "/home/alobo/.qgis//python/plugins/image_clipper/dlgimageclipper.py", line 228, in ClipImagegdal_merge(gdalstring)File "/home/alobo/.qgis//python/plugins/image_clipper/gdal_merge_bb.py", line467, in gdal_merge fi.copy_into( t_fh, band, band, nodata )File "/home/alobo/.qgis//python/plugins/image_clipper/gdal_merge_bb.py", line241, in copy_into nodata_arg )File "/home/alobo/.qgis//python/plugins/image_clipper/gdal_merge_bb.py", line48, in raster_copy nodata )File "/home/alobo/.qgis//python/plugins/image_clipper/gdal_merge_bb.py", line84, in raster_copy_with_nodata t_xsize, t_ysize )File "/usr/lib/python2.5/site-packages/osgeo/gdal.py", line 831, in ReadAsArrayimport gdalnumeric File "/usr/lib/python2.5/site-packages/osgeo/gdalnumeric.py", line 1, in from gdal_array import * File "/usr/lib/python2.5/site-packages/osgeo/gdal_array.py", line 7, in import _gdal_array ImportError: dynamic module does not define init function (init_gdal_array) 2. zoom-to-point plugin After installation, I get the same message as reported by Giovanni (just tried 09/1 10:22 am GMT+2) "The plugin seems to have been installed but I don't know where...." But the directory gets to its right place ant the plugin works. Just a suggestion: Could you add (optionally) a circle around the point? Even if it is thecentral point, sometimes you want to make sure it's around the feature you want.Agus Bob Bruce wrote:Hi:I have a plugin available that people may be interested in testing. This can be used to extract and combine portions of one or more image layers in QGIS. I have only used this on Windows but hopefully it would work OK in Linux also. You can get it and some testdata by going to the page: http://www.mappinggeek.ca/QGISPythonPlugins/Bobs-QGIS-plugins.xml . Wehave been using this plugin a lot at my workplace to extract the useable portions of scanned photography that we have georeferenced using the GDAL Georeferencer plugin.There is also the zoom-to-point plugin that I have tweaked to work better with zoom levels.Bob Bruce------------------------------------------------------------------------No virus found in this outgoing message.Checked by AVG - www.avg.com Version: 8.5.409 / Virus Database: 270.13.71/2335 - Release Date:08/30/09 06:36:00------------------------------------------------------------------------_______________________________________________ Qgis-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-user_______________________________________________ Qgis-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-user
