Hi JoSn, If you can't get it from GetColorTable() I believe that the problem is that the HDF driver doesn't recognize the internal schema of the files you have. If it was one of the well know formats it should work, like if you download MODIS Vegetation product for example. So I can foresee three options for you:
- If that is a well know HDF product, file a ticket as a request for improvement, if not: - If you need to process several files of that product the color tables should be the same: use some kind of HDF tool to dump the colors on a text file and edit a GDAL VRT file. Maybe you can find the text code in plain text on the product description. - Try to access the HDFEOS libraries from your C# code - that is the hard one - and find the color table yourself. I hope that it helps, Ivan > -------Original Message------- > From: jor sion <[email protected]> > Subject: [gdal-dev] how to access Image palette in HDF files > Sent: May 07 '09 03:45 > > Hi, > � > I am using GDAL in CSharp to read the information from HDF files. > � > [LINK: mailto:[email protected]] I do not know how to access the > information Image palette in HDF files.
