Photoshop handles the alpha band. You can try specifying -dstnodata:

Perfect. I guess I missed this, digging around in the API instead of the format

Thanks!

Hi Everyone,
I am wondering if there is a build (beta or release) of GDAL for Python 3.2
on the Windows 64bit platform. I have been browsing around the ticket area
of the website and there appears to have been code entered in to make
GDAL compatible with python 3.2. However, I cannot find where

Hello list,
I have been reading through the documentation to see if it is possible to add a
subdataset to a format that supports it (NITF).
It seems like based on the data model it is possible to read those by
extracting the name and then reading it as normal as if that was the file name.

It worked!
Thanks a lot for your help Chaitanya.
Seriously, thanks a lot.

Migel,
You have the corner coordinates. Now you need to know the pixel value at a
particular position. You can calculate the pixel value from the projection
coordinates using the affine transformation coordinates. You can get the
these coordinates using GDALDataset::GetGeoTransform() method. Knowi

Is there another way to tranform a 3D polygon to 2D thorugh ogr2ogr?

Ahmet,
You can clip a shapefile using ogr2ogr using the option -spat [1]. There are
more options to control the clipping of polygons intersecting the border.

ahhh ok, so "ar" is a valid command, a command that's probably not on my path.
I'll have to check that out.

Hi,
I've tried that, but without any success. I have no problem warping the

Chris,
This could happen when you try to transform an image that is outside the
defined area of the destination projection.
Cut the raster to the destination projection's extents and try again.

Solimyr,
For shapefiles just copying and renaming the .prj file might be enough.
Extents can be computed and stored using the ogr2ogr utility.
If copying the .prj file didn't work, you can use the -s_srs option in the
ogr2ogr utility. You can get the SRS WKT from the ogrinfo output.
Of course, y
Hi guys,
I have two shapefile with same features but one miss the extent and the

GetFeature(n) returns the feature such as feature.GetFID() == n, so attribute or

If you want to iterate over the feature of the layers, and take into account
filters, you have to use GetNextFeature(), until it returns null.
