Thanks, Phil, for respond. I agree: docs are pure. I have the same manual.txt for libgeotiff. Still can not find any reference for return from TIFFGetField(tif, TIFFTAG_GEOASCIIPARAMS, &data) command. The other two return number of elements as a parameter: TIFFGetField(tif, TIFFTAG_GEOKEYDIRECTORY, &size, &data); TIFFGetField(tif, TIFFTAG_GEODOUBLEPARAMS, &size, &data); TIFFGetField() description in tiff-3.8.2\html\man\TIFFGetField.3tiff.html shows in "Autoregistered tags" sample that ascii tag should be handled the same way. But real code is different. I want to use TIFF approach to handle tags (shorts, doubles, ascii) as an arrays rather then GTIFFKeySet/GTIFFKeyGet for each tag. Thanks to gdal it handles geoTiff great. Any help, please!
