Experienced users are all too familiar with the problem.
The reason for the degradation is because bitmapped, or raster, image types are limited by their pixel resolution. The resample command in most imaging software uses a process called interpolation for increasing the size of an image. The interpolation process estimates the values of the pixels the software needs to create based on the existing pixels in the image. Resampling via interpolation is better than resizing an image without interpolation, but results in serious blurring of the resized image, especially in areas where there are distinct changes in color. The STN files can then be opened at any resolution you choose.
