At the moment, to read a raster into a slice you are using GDALRasterIO, which doesn't provide a way to select a resampling algorithm.

If I'm not mistaken, GDALRasterIOEx has an extra option which could be used to do that.

Is there any way to pass a sampling algorithm (GDALRIOResampleAlg) to read_as or read_into_slice?

I tried to implement my own read_into_slice function but RasterBand.c_rasterband is private and I'm not sure how to proceed.

Cheers!

I guess we should change the read_as and read_into_slice methods to use GDALRasterIOEx. It would be great if you could provide a PR for this. You could have a look at GdalOpenEx in dataset.rs for an example.
