I am using Q16-AnyCPU version to resample a 24-bit TIFF image

   using (var image = new MagickImage(imageFileName))
            {
       
                image.Resample(new PointD(600));


                
                image.Write(outputFile);
            }

The problem is that the output image is not 24-bit but 8-bit, and the loaded image is also 8-bit. What am I doing wrong?

That's the command I need to implement:

convert input.tif -units PixelsPerInch -filter Point-resample 600 -type TrueColor output.tif

You will need to set the colortype of the image to truecolor

That helps, but why isn't it loading image properly right from the file? There's a TrueColor image in, I expect that ColorType would be TrueColor after the image is loaded.

And is it possible to specify the filter for the Rescale somehow (Point in command-line equivalent?)

Yes. Eg at the CLI, give "-filter Box" or whatever before "-resample".

Not in the CLI, I meant Magick.NET
