A method (30) and apparatus (10) for scaling selected areas of a graphics display. The method (30) includes removing distortion-sensitive information from the graphics display, scaling or converting the format of the distortion- nonsensitive information, such as from one aspect ratio to another, and then compositing the removed distortion-sensitive information with the scaled distortion-sensitive information. Alternatively, the removed distortion-sensitive is scaled, distortion-free, before combining it with the scaled distortion-nonsensitive information. The apparatus (10) uses a recognition comparator (16) to identify distortion- sensitive information, a graphics remover (18) to remove the distortion-sensitive information, a first scaler (22) to scale the distortion-nonsensitive information, a second scaler to provide distortion-free scaling of the distortion-sensitive information, and a compositer (26) to combine the distortion-sensitive information with the scaled distortion-nonsensitive information. A graphics display can be converted using a conversion process that introduces distortion, yet distortion-sensitive information, such as logos, are not subject to such distortion.
