Mo,
See, GDAL does not implement the code that actually reads the ECW
format. The GDAL ECW driver just make calls to a external library. That
library is provided by the company that holds the copyright for that
format [1]. So you would need to ask and negotiate with then first.
But I believe
Mateusz,
License issue can be resolved through negotiation. Then back to the technique
issue: Is it a big thing to change ECW to support 16-bit imagery?

Sometimes it's a good idea

Wrong question. The correct one is: are you allowed to change
anything in ECW to support anything what is not supported?

D'accord.

In the past I've opened threads on GDAL/Mono. This may have been too specific,

Just looking for feedback. Has anyone succeeded in getting the bindings to work
in Linux? I realize the buildbots generate

Actually...
GetStatistics dows the same as ComputeRasterStatistcs()
That is confusing...

Hi all,
When I used gdal_translate to convert a 16-bit QuickBird image to a ECW
JPEG2000 compressed NITF image I got a

Note I've ported ogr2ogr to the Java bindings, so I guess it should be
relatively easy to port it to C# as both languages are pretty close.
Porting it from C++ to Java was rather straighforward (but very boring!).
Replace NULL by null, TRUE by true, FALSE by false, -> by ., printf by
System.out.
Hi Ivan,
I don't think there's a bug.
The C API for ComputeBandStats is :
CPLErr CPL_DLL CPL_STDCALL
GDALComputeBandStats( GDALRasterBandH hBand, int nSampleStep,
double *pdfMean, double *pdfStdDev,
GDALProgressFunc pfnProgress,
Hi there,
I believe that ComputeBandStats() should return 4 values min, max, mean and
stddev) [1] but the Python API is
returning just mean and stddev.
python:
>>> bd.ComputeBandStats()
(9.0071713001936118, 11.350094331448236)
>>> bd.ComputeRasterMinMax()
(-1.789618530273, 31.146185302
Hi,
I have written a gdal driver and would like to hook this into an
existing viewer (public domain) to demonstrate the code. The driver
makes a fair few changes to the GDAL API so it isn't as simple as just
adding to the format list.
Would I be better to use openev or openev2, or perhaps
Or do something ugly like use a .asmx to call your ogr2ogr cmdline as a

Hi,
If you want to use GDAL in C / C++, take a look at the tutorial at
http://www.gdal.org/gdal_tutorial.html.
It is really straightforward, I used this for the integration of GDAL in our
modules and it worked fine.

Duarte,
Why not create a view that has the TRANSLATE and TO_CHAR and then use that
in OGR.

Dear all,I want to use GDAL library in my project using QT.How could i use this
library for Reading and writing the Raster images (i.e.

I'm correcting the subject of the message - the problem is with NVARCHAR fields
(not varchar2).
It seems this relates to utf issues/limitations in ogr.
If I could use SQL functions this could be solved by the database itself. Like
using TO_CHAR(field_name) or TRANSLATE(field_name USING CS_CHAR).
Hi,
You'll have to re-implement the logic in ogr2ogr.cpp by using the
ogr_csharp.dll.
Refer to the following thread for more information:
