It depnds. If the output type is Byte, then yes values will be clamped to 255
Hi all,
It seems that when gdal_translate scales e.g. -scale 0 6000 0 255, the
values above 6000 also get set to 255. Can anyone confirm this for me? I
don't see the destiny of those pixels explained in
http://www.gdal.org/gdal_translate.html.
Thanks,

The specific C API that I am thinking about is the Warp API:
http://www.gdal.org/warptut.html
That page includes a number of performance enhancements which might also
make for potentially interesting work for a summer student.

One idea I would like to see considered for GSoC would be completing the
GDAL API for Python to include all the functionality that currently exists
for C. I wish I were experienced enough with the code base to mentor it,
though, so if it doesn't have a mentor I imagine that it can't happen.

I'm currently trying to grab a map image from a wms using gdal and save it to
my local machine. The call that I'm trying to replicate inside of my wms xml
file is ->

Yes, there are differencies in the data model, but that could serve as an

I think this is a good idea for GSoC.

Hi,
I am having a very strange issue when trying to use a custom error handler
in GDAL on windows.
The following simple example illustrates it:
#include
#include
using namespace std;
static void logGDALError(CPLErr eErrClass, int err_no, const char *msg)
{
cerr << "GDAL Error: " <<

Hi,
The Shape driver work with qix file internally (speed up spatial
filters). You can find if qix file exist with cpl function: CPLCheckForFile
Also you can create own QuadTree with: CPLQuadTreeCreate
