View Thread: When will magnfication in Windows Picture and Fax Viewer interpolate the image?
  • User profile image

    Consider a bitmap which is a series of 1 pixel wide vertical lines alternating between white and black. What should the interpolated image look like?
    Considering that this application is a fax viewer (and faxes are often made up of black and white pixels using CCITT compression), it is surprising that they would choose to interpolate, in my opinion.
