[Gdal-dev] Problem about black frame around a raster ...

[Cristina Negri Arnoldi]

  Hello,

  I have a question about the GDALWarp usage:

  after the transfer of raster image (gray scale orthophoto) from one coordinate system to another (Gauss Boaga - UMT ED50) around the orthophoto it appears a black frame that remain and create visualization problems when I proceed with the mosaic of many orthophoto.

  How can I resolve this problem ? There is in GDALWarp a way (options) to render this black frame transparent during the process of coordinate system transformation ? And what is the write sintax ?

  Waiting for your answer ...

  Thank you !
