[Gdal-dev] Testing creating and opening raster datasets

[Ari Jolma]

Hi, below is an output from my test script for gdal.pm. It goes through 
all available drivers and all announced datatypes, and creates a dataset 
and then opens it and checks if the size is ok. Looks good, only minor 
issues:

- What does the "unsupported combination.." mean and how to detect it 
before creating a dataset?
- ENVI hdr reports that it can create "UInt32Float32" datatypes, this is 
a bug in envidataset.cpp:1375.
- Atlantis MFF2 (HKV) Raster announces that it can create datasets of 
more types than it actually can.
- It takes a bit of guessing (I hard coded that into the test script) 
what filename to give to the Open function to make it succeed. Is the 
extension available somewhere in the metadata? (sorry, too lazy to look 
now).
