The variety of displays used to browse and view images has created a need to adapt an image representation to constraints given by the viewing environment. In this paper various methods of adaptation to a small display size are introduced with focus on adaptation of document images. Compared to photographic images, document images pose an even greater challenge to represent on small size displays. If a typical down-sampling of image data is performed, we not only loose some high-resolution data, but also semantic information, such as readability, recognizability, and distinguishability of features. We explore various ways of controlling document information such as readable text or distinguishable layout features in different visualizations applying specific content-dependent scaling methods. Readability is preserved in "SmartNails" via automatic content-dependent cropping, scaling and pasting. Content-dependent iconification is proposed to provide distinguishability between layout features of document images. In the case of multi-page document content a rendering in form of a video clip is proposed that performs content-dependent navigation through the image data given display size and time constraints.
