Unicode type release name (str type in python 3) must be compatible
with the saying.

Fixing the error would be easy for the relevant python devs. But if
the change was introduced in 3.0 (`type(QGis.QGIS_RELEASE_NAME)` gives
me `` in QGIS 2.14. Not sure that it was technically
possible to keep str type for the constants), QGIS 2.16 users didn't
have to wait for the relevant plugin devs to release a modified
version.

Thanks,
Minoru

[Qgis-developer] Unicode type QGIS_RELEASE_NAME and QGIS_VERSION

[Minoru Akagi]

Hi,

Just a quick note for python plugin devs.

I received an error report related to QGis.QGIS_VERSION constant [1].
In QGIS 2.16, QGis.GIS_RELEASE_NAME and QGis.QGIS_VERSION constants
have been changed to unicode type. I guess that the change is
necessary for unicode release name support.

With QGIS 2.16, encoding GIS_RELEASE_NAME/QGIS_VERSION with no
explicit character code specified causes UnicodeEncodeError (try
`str(QGis.QGIS_VERSION)`) and a few plugins seem to be affected (e.g.
profiletool, numericalVertexEdit, etc).

[Qgis-developer] QgsPluginLayer.writeStyle() must be overridden?

[Minoru Akagi]

Hi devs,

I'm looking forward to the next wonderful release, and now testing
TileLayerPlugin with qgis-dev (OSGeo4W64), I sometimes encounter the
following error message while loading a project with a plugin layer.

NotImplementedError: QgsPluginLayer.writeStyle() is abstract and must
be overridden

According to the API doc [1], QgsMapLayer.writeStyle() has been added
in 2.16 and is reimplemented in QgsVectorLayer and QgsRasterLayer, but
does not seem to be reimplemented in QgsPluginLayer.

Can QGIS core avoid raising this error? Or should all the subclasses
of QgsPluginLayer override writeStyle()?

[Qgis-developer] Geometry type conversion of 2.6

[Minoru Akagi]

Hi,

I just found size of .shp file increases more than twice (2900 bytes
- 6500 bytes when it has 100 points) when I saved a point layer as a
shapefile. I didn't edit the layer anything, but the geometry type was
converted from Point to Multipoint.

Maybe this must not expected behavior. Is this a big bug of 2.6? See
also #11542 and #11597.

I think an option to make the background color of map canvas

automatically enabled.

Re: [Qgis-developer] [Qgis-tr] size of translations, use a distinct repo?

[Minoru Akagi]

Hi,

2014-10-31 1:12 GMT+09:00 Werner Macho werner.ma...@gmail.com:
 Other thing is that I think about only updating all translations in
 source only every two weeks (or probably only in front of a release)
 as the translation should be done in transifex anyway. And only
 updating the english source in transifex (and master of course).
 Pros: even smaller and less commits,
 Cons: Some translators often like to see how it looks like and I
 understand that from time to time you want to see if it fits.

 What do you think about that?

We can download the latest ts file from Transifex and build it with Qt
Linguist or lrelease command. So just one time update of translation
files in GitHub before every release is enough for me. I use a batch
file (below) to build it, and then check the translation appearance
with the qgis-dev of OSGeo4W.

The message location information must be heavy for the git repository,
but it may be useful for translators. I use it to find the relevant
source code, for example, to know what string %1 is replaced with (is
it replaced with a number? layer name? or error message?). We can see
the name of context that a message is located, but it is not always
helpful to find the location of message. Without location information,
I'll find the source location using search from files function of
text editor, but it is not efficient way.

Is it possible to upload the source ts file with location information
to Transifex, and clean up location lines just before the translation
files are committed to the git repository?


### build_ts.bat
---
call C:\OSGeo4W64\bin\o4w_env.bat

SET TS_DIR=translations\QGIS.qgis-application
SET TS_LANG=ja
SET DEST=C:\OSGeo4W64\apps\qgis-dev\i18n\qgis_%TS_LANG%.qm

REM lrelease.exe is included in qt4-devel package of OSGeo4W

Re: [Qgis-developer] symbolForFeature() does not works?

[Minoru Akagi]

Hi Alexander,

2014-07-04 0:53 GMT+09:00 Alexander Bruy alexander.b...@gmail.com:
 Hi all,

 seems symbolForFeature() method does not works as expected for most
 renderers:
  * QgsSingleSymbolRendererV2 — returns feature symbol
  * QgsCategorizedSymbolRendererV2 — returns None and in debug output
 I have message saying there are no hashed symbols!!!
  * QgsGraduatedSymbolRendererV2 — just crashes QGIS
  * QgsRuleBasedRendererV2 — returns None

 All tests made with point shapefile. Here is code snipped I used (load vector
 layer and activate it first):

 layer = iface.mapCanvas().currentLayer()
 feat = layer.getFeatures().next()
 renderer = layer.rendererV2()
 symbol = renderer.symbolForFeature(feat)

 For me this is major issue that makes difficult to develop plugins that works
 with layer symbology (e.g. symbology import/export/conversion)

 Anyone confirms? Should I open a ticket?

Matthias Kuhn showed me a workaround
(http://hub.qgis.org/issues/10096#note-1). My code is like this:

# initialize symbol rendering
renderer = QgsMapRenderer()
layer.rendererV2().startRender(renderer.rendererContext(),
 layer.pendingFields() if
apiChanged23 else layer)

for f in layer.getFeatures():
  symbol = layer.rendererV2().symbolForFeature(f)
  print symbol.color().name()

layer.rendererV2().stopRender(renderer.rendererContext())

Hi Roberto,

2014/1/20 Geo DrinX geodr...@gmail.com:
 I have some other suggestion   :)

 I am testing  with more than one image and DTM files.

 I find that, in this case, it would be useful to have an automatic selector
 of the DTM or DSM layer  (I don't know how, but, for example, it could be
 the layer that starts with DTM_)

Sounds good.

 Other problem is: if there are more than one  DTM_  layers, it could be
 possible to have together clipped in the output ?   Or, only one is possible
 to have ?

Only one. You should merge DTM files into one in advance or make use
of vrt file.

 If I well understand from documentation, a .vrt file is an xml index of many 
 raster files.
 It is correct ?

Hi Roberto,

The way of getting elevation values from 3 or 4 bands image data seems
a little strange. AFAIK, at least it is not common, and WCS is a more
ordinary way to get elevation data through internet access. Using QGIS
API (QgsRasterDataProvider) in addition to GDAL API to support more
data sources (1 band rasters) may be a good idea.

 Hi Minoru,


 You can do it with latest code on GitHub.
 https://github.com/minorua/Qgis2threejs



 I tested it   :)

 I have an idea and a suggestion:

 if a level was a WMS PNG24 or PNG32 of a DTM, do you think it would be
 possible to use it to create 3D with your plugin?

 This would be a very useful feature :)

 Roberto

Hi gene,

I'm sorry for the inconvenience, and thank you for your concrete report.
I've changed the plugin code to do DEM warp with gdal.ReprojectImage
instead of gdalwarp program to store warped DEM data in memory raster,
so it may work in also Mac OS X, I guess. I will also fix the other
issue. Feel free to comment about the plugin.

Thanks,
Minoru

2014/1/3 gene martin.lal...@gmail.com:
 Hi Minoru,

 First of all, many thanks for your plugin.

 As I use Mac OS X and the QGIS version of Kyngchaos, the path of gdalwarp is
 /Library/Frameworks/GDAL.framework/Versions/1.10/Programs/gdalwarp but this
 QGIS version does not recognize  the PATHs defined in the UNIX environment
 of MAC OS X ie:

 export PATH=/Library/Frameworks/GDAL.framework/Programs:$PATH
 which gdalwarp
/Library/Frameworks/GDAL.framework/Programs/gdalwarp

 So I had to make some changes in your qgis2threejs.py script to run on Mac
 OS X with this version of QGIS.
 I know that you can not change your script for a specific case but I hope
 that this will help Mac users  who want to use your plugin.

 General:
 --
 The os.system() works but it is marked as deprecated in the doc , so I use
 the Python module subprocess to make the job (as in Processing or the old
 Sextante) and it works:

 original line 185
 os.system(cmd.encode(fsenc))
 my solution:
  proc = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE,
 stdin=subprocess.PIPE,stderr=subprocess.STDOUT)
  proc.stdout.read()

(subprocess.check_call(cmd,shell=True) does not work )

 Specific to Mac OS X:
 -
 - I change the line 182
 cmd = gdalwarp  + u .join(options)
 in
 cmd = /Library/Frameworks/GDAL.framework/Versions/1.10/Programs/gdalwarp
 + u .join(options)

 - and I have removed the conditional statement
 #if not os.path.exists(demfilename):
 #

 - the same with line 160 which becomes:

 #options.append(--config GDAL_FILENAME_IS_UTF8 NO)

 - a final command which works  is, for example:

 /Library/Frameworks/GDAL.framework/Versions/1.10/Programs/gdalwarp -r
 bilinear -te 201132.706856 87080.384980 206579.284551 91865.013464 -ts 214
 188 -t_srs EPSG:31370 /Users/Shared/Dropbox/my.asc
 /var/folders/vu/vu099NovH-KZpE5TEa83BU+++TI/-Tmp-/dem20140101164100.tif

 Cosmetic
 ---
 As I still use Snow Leopard version (witch uses Python 2.6, I know, I know,
 it is old, but...), the line 48
   locale= localePath = os.path.join(plugin_dir, 'i18n',
 'qgis2threejs_{}.qm'
 becomes
   localePath = os.path.join(self.plugin_dir, 'i18n',
 'qgis2threejs_{0}.qm'.format(locale))

 (working with Python 2.6.x and 2.7.x versions)

Hi Roberto,

Thank you for your suggestions.

2013/12/31 Geo DrinX geodr...@gmail.com:
 The only thing that I find to be improved is the fact that it opens a new
 web page, and that is opened in QGis an information panel on which (if any)
 choose the DEM layer.

 For me, the panel should be confined in a panel on Settings, and instead
 the function must be called directly (and using the same web page)

 Sure, with this, everything would be (even more) immediate and amazing.

I will increase the number of items in the dialog. I have already
implemented multiple resolution output that has both detailed close
view and rough distant view, and would like to challenge vector data
output. I think it is good to provide an option to output simple one
by 1-click from the toolbar button so that user can preview easily. I
will also consider an option to open page in existing tab.

 Also I suggest to use a temporary directory inside the plugin directory, as
 in my GEarthView plugin.

I'll consider it. If you have some reasons that temporary directory
inside the plugin directory is better than system temporary directory,
please tell me.

Minoru

 Possibly a missing lib, or missing webgl support? Any hint?

Hi Marco,

2013/8/7 Marco Hugentobler marco.hugentob...@sourcepole.ch:
 Btw., I noticed that creating new attributes with non-latin characters does
 not work. It however seems to work with utf-8 encoded shapes. Is it a dbf
 limitation or a QGIS bug?

I guess it's a GDAL issue but, fortunately, it has been already fixed.
With GDAL 1.10, creating attributes with non-ascii characters works
fine even if the Ignore shapefile encoding declaration option is not
checked.

I guess that the 3rd argument (fields) should be a QgsFields object.
You can create it like this.

fields.append( QgsField( desc, QVariant.String ) )

Hi,

Problems on this topic have been reported several times.
- OGR SQL: REPACK fails if filename includes non-ascii characters,
http://hub.qgis.org/issues/8391
- Fail create a spatial index with shape file that contain Japanese in

- Points are deleted but still exist, http://hub.qgis.org/issues/6134
- spatial index fails, http://trac.osgeo.org/qgis/ticket/1295

I think these problems have not been completely fixed. Please see
#7794 and #8391 for the steps to reproduce the problems. I would like
to fix the problems before the 2.0 release. There is a pull request to
fix the problems.
https://github.com/qgis/Quantum-GIS/pull/584

Could any developers review the pull request?

Re: [Qgis-developer] Adding a feature to a layer with joined fields

[Minoru Akagi]

Hi,

2013/5/30 Denis Rouzaud denis.rouz...@gmail.com:
 Hi all,

 Regarding blocker #7072, I wonder if it really makes sense to have joined
 fields than can be filled by the user in the edit form while creating a
 feature. These fields should not be edited at all.
 I would suggest not to show them at creation and to disable the joined
 fields while editing.

 What do you think?

I think it's right. In 1.8, joined fields are editable. Input values
are displayed in the attribute table, but their values are not saved
when I save the layer as a new file.
My patch[1] does not hide joined fields in new feature form, but it
makes joined fields uneditable. As soon as we create a new feature on
join layer, fields in the joined table are bind to the new feature
corresponding to the value of the target field. I believe that editing
join layer should work well with two patches[1][2].

Re: [Qgis-developer] Is there anybody interested whether QGIS 2.0 will support non-Latin1 Shapefiles?

[Minoru Akagi]

Hi Borys,

I agree to specify the ENCODING option. LDID/87 does not have definite
meaning (depending on the environment), so avoiding to write shapefile
with the value would be nice. If the output encoding is UTF-8,
QGIS/OGR will generate cpg file that contains UTF-8. This behavior
must be ideal. In case of the other encoding, even if there is a
problem with the content of a cpg file (e.g. use in another
application. I am not much sure about cpg file), the user will be able
to fix it easily.

Similarly, how about specifying the ENCODING when creating new
shapefile (in createEmptyDataSource())?

 And one longterm:
 - after iconv conversion tio UTF-8 the layer doesn't remember the source
 encoding, so it's impossible to preserve it e.g when saving from Table
 Manager.

In QgsVectorFileWriter, how about always using SHAPE_ENCODING= ? It
will solve the problem and never make any encoding conversion failure
with current encoding listbox.

 I also added Shift-JIS to the Shapefile Encoding Fixer plugin. Please let me
 know if any of you needs (or just knows) another important encodings.

Thank you for your work on the plugin.

Minoru Akagi
