Hi, has anyone used the interpolation subpackage for image resampling? more specifically, i'm trying to write a program in C# which would reduce images using the bicubic interpolation, with the ambition of obtaining results which are as good as Photoshop's. I've tried using spline2dresamplebicubic by passing a 2d int array, populated by C# standard Color.FromArgb() (data drawn from a Bitmap object). Unfortunately, the result is ridiculously off, which only means that the ARGB data is not the right data.. Should I apply the resampling for each base color separately ? I'd appreciate any feedback on this, thanks. |

Yes, each base color should be resampled separately. |
