[Qgis-developer] Raster providers

[Tim Sutton]

Hi Radim

I did some testing too. Having otf projection is coool! Id did run
into some problems with my paletted image[1] though.

If I open the image in QGIS default session (i.e. no OTF projection)
it displays fine [2].
If I enabled OTF Projection (using 900913 Google Mercator) the image
displays as all grey [3].
If I set the CRS to the native image projection (EPSG:32734), the
image does not show at all.

I still need to test with other image types properly but thought I
would give you this feedback so long.

Also I noted that for greyscale images they always seem to load with
min 0 / max 0 and I have to manually go into properties to load them
from the layer.

By the way if anyone else is using git-svn and wanting to test Radims
branch, this was the process I used to add it as a local and remote
branch in my local repo:


git config --add svn-remote.raster-providers.url
https://svn.osgeo.org/qgis/branches/raster-providers
git config --add svn-remote.raster-providers.fetch
:refs/remotes/raster-providers
git svn fetch raster-providers -r 15231
git checkout -b raster-providers -t raster-providers
git svn rebase raster-providers

Thanks to Juergen for pointing me to the relevant crannie in the
internet that showed how to do that.

Regards

Tim
