Hi Chaitanya
Thanks again for the hint. I have now to experiment with GeoTransform.
I first let generate a valid VRT to start doing a "% gdal_translate
-of VRT myinputfile.gif myinputfile.vrt". But I still have some
issues:

Thank you for your answer.
In gdal-translate.exe there is an option of -scale pixel range.
How can i set this parameters from code (visual c++) ?

You can use the GDALRasterBand::SetScale() and GDALRasterBand::SetOffset()
methods[1]. There are methods to retrieve them too.

I have warped modis with swath2grid and mosaicked it with mapserver, I
have not seen that issue.
also you don't need to use a vrt to mosaic, this can be done with one
gdalwarp call.
gdalwarp file1 file2 file3 outfile

Nikolaos,
I believe the only limitations will be ones imposed by the shell/os on
the number of arguments that can be passed to an app (2^15?), and the
cpu and memory resources available.

Hi All,
I have 60 or so asciiGrids of climate data that I would like to tun into
PNGs, with the climate values classified by color. I would like to
script this process using Python. Is there a way to do this with GDAL?
Or if not, is there any other open source way to do this?
Thanks,
Stev
Dear sir,
I've been trying to build GDAL180 64-bit on VS2008 but there are always 163
errors and 2052 warnings. I uncomment WIN64=YES, and try all the ways found on
internet, such as commenting ODBC, deleting '@XX' in line 47-50 of makefile.vc,
setting up VC++ directories for platform 'x64'. Ho

Stephen,
The docs for rgb2pct.py script [1] has an example that shows how to convert
to a paletted image using hand made VRT file.
You can use the "-of PNG" option to set the destination format as png and
the -pct option with your VRT file.

Hello all,
I have acquired a Ricoh digital camera with a GPS unit built into the camera. There is also a compass built in as well.
The GPS co-ordinates are stored in the exif header of the jpeg. I have figured out one way to extract them.
I'm hoping that the compass bearing is also recor
