Hi, I'm using the GDALWarp api from C++ to reproject and cut various input images. In general this works very well for my purposes, except that for paletted images I have to use NearestNeighbour resampling,
I would like to use Bilinear or higher order resampling, and wonder if there is any way to expand a paletted image to true RGB during the warp process, so I can use these resampling methods. Alternatively, is there a way to do this conversion (from code) before the warp without having to run through the entire image in memory? - Thomas
