I'm kind of stuck in QgsMapToPixel as that class currently has no
knowledge of map "center". It has both min and max values for the Y
direction but for X it only has min value. 

There is also no "viewport size" to compute xMax from, so basically
I'm still missing the center of the map, which is what I would
have liked to use as anchor point for rotation.

Should I refactor the class to additionally hold a center, or an xMax ?

AFAIK Processing does not import the raster, but uses it as an external data 
source
(if not, it should).

quite possible; however, maintaining multiple calcs seems more of a burden than 
an
advantage.

all the best.

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

2014-11-21 Thread Giovanni Manghi 
Hi Andreas,

> It may also be an issue with SAGA or GRASS directly.

I have also tested a very large raster (8gb) and SAGA seems to choke
also when used natively from the cli interface.

grass of course does the job, especially when you use the grass data
model from the cli, native grass gui or qgis plugin. Inside processing
large raster suffer from the overhead that is needed to import/export
the raster to, and out of, a temp location.

gdal does the reclass job very quickly and I should be able to add the
tool to processing.

I agree anyway that it too bad that the qgis raster calculator (and
georeferencer) are drawing so little attention. Maybe there isn't much
people that uses them?

cheers!

[Qgis-developer] QGIS master compiles against Qt5

2014-11-21 Thread Matthias Kuhn 
Hi,

Qt5 support has just been merged to master (78c5195)

This should not make any difference if you want to compile and link
against Qt4.

If you want to have a QGIS version that makes use of Qt5, please not that

  * You need to have the dependencies also linked against Qt5. You most
likely will not find that prebuilt and will need to do it yourself.
Segfaults of crssync when compiling indicate that there are dependencies
linked against Qt4.

  * In particular, check the following libraries:
* QScintilla2
* QWT
* QWTPolar

  * Python bindings are completely untested (Both, PyQt4 and PyQt5)

  * The class QgsHttpTransaction is no longer supported.

Have fun
Matthias

Right, that was my idea of threating it like a reprojection.

That's possibly what I've done by implementing rotation in QgsMapToPixel,
as I do see features and label positions all correctly rotated. Only,
the PAL view on the source layer seems to be still the original one, as 
in "parallel" mode those labels are NOT parallel to the rotated but to
the original lines (I think, not really sure).

If you want to take a look, I pushed a branch here:
https://github.com/strk/qgis/tree/rotation

I think next I'll work on a widget to make it easy to specify rotation
in the GUI so further tests are easier to conduct.

Re: [Qgis-developer] Problems with developing custom c++ qgis application with QtCreator and MSVC2008 on Windows

I use the same environment of Qgis to write c++ plugins:
http://htmlpreview.github.io/?https://raw.github.com/qgis/QGIS/master/doc/INSTALL.html#toc14

to add raster layer:
m_ptInterface->addRasterLayer("http://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer?f=json&pretty=true","raster";);

Do you have a system setup that can write qgis c++ application? If you do, can 
you create a valid raster layer from that?
