I have tried to read a one banded tiff file (as seen below) and convert it to a bitmap, but I fail. My environment is CSharp and I use the swig interface. I have compiled and use version 1.4 of GDAL.
I have found a sample that describe how to use GDAL to convert a tree band image to a (DOTNET-) bitmap, but my image only have one band. How should I do in that case?
I tried to find the extent information and as I understood I should use the dataset.getMetadata but I had no such a function available. I had getMetadata_List and getMetadata_Dict, but no one gave me the extent information. What are missing?
Is it possible to create a bitmap based on a smaller rectangle of the input dataset?
