Industry:Telecommunications
In facsimile, the signal resulting from scanning a maximum-density area of the object.
Industry:Telecommunications
In facsimile, the ratio of the level of the white signal to the level of the black signal. Note: Signal contrast is usually expressed in dB.

In facsimile, the mode of scanning lines across the shorter dimension of a rectangular original. Note: CCITT Group 1, 2, and 3 facsimile machines use portrait mode. 2. In computer graphics, the orientation of an image in which the shorter dimension of the image is horizontal. 3. An orientation of printed text on a page such that the lines of text are perpendicular to the long dimension of the page.
Industry:Telecommunications
In facsimile, the mode for scanning lines across the longer dimension of a rectangular object, i.e., rectangular original. 2. In computer graphics, the orientation of an image in which the longer dimension is horizontal. 3. An orientation of printed text on a page such that the lines of text are parallel to the long dimension of the page. Note: If the page contains an image, such as a picture, and the page is viewed in the normal manner, the long dimension of the page would be parallel to the line that joins the eyes of the viewer.
