Re: [gdal-dev] gdalenhance -config file how you do linear interpolation of the colors?

2012-02-09 Thread Chaitanya kumar CH
Nikolaos, The gdalenhance utility is not really recommended. I don't know the config file format. GDAL's VRT driver[1] supports a look-up-table that works with linear interpolation. In it, you specify pairs of corresponding values in source and destination rasters. The intermediate source values

Hi, I think, OGR (and therefore MapServer too), is not taking care about axis orientation of incomming data, acting as WFS 1.1 client. Result is flipped data and I do not know, how the software recognizes, that axes order is different (apperently, it does not). We have setuped generic WFS 1.1 ser

[gdal-dev] Multithreading, deadlock with proj.4

2012-02-09 Thread Roger Phillips
Hello folks, I recently tried to use the GDAL 1.9.0 API from multiple threads. However, they may arise a deadlock situation where one thread hangs in the cpl_multithread.cpp CPLAcquireMutex function and others hang in the pj_acquire_lock() function of the proj.4 4.7.0 API blocking each other.
