<DIV>Thk u for your reply.</DIV>
<DIV>I read the tuorail.but I think that will not satisfy my need.</DIV>
<DIV>I want to create a .png file,and it only contains height data and not contains metadata, a coordinate system, a georeferencing transform, size of raster and various other information,I find that the Create() and CreateCopy(). is will create a file that contains all the things.</DIV>
