Digital images allow a single image to be output in any or all of these media with little or no modification. All of these media work by digitizing an image - dividing the image into a grid of cells called pixels. The resulting matrix of pixels is called a bit map. The simplest bit maps contain only one bit of information for each pixel which means that they can only be black or white. It may be helpful to supplement the information in this article with the user guides to some of the graphics software.
Resolution is a measurement of clarity or detail.
The larger the matrix of pixels or bit map, the more detail that can be captured in the image. In digitizing the scanned image the software converts the dots into a matrix of pixels. The most common input devices in landscape architecture offices today are the flatbed scanners that digitize drawings or photographs. In terms of the resulting resolution of digitized images they are among the most sophisticated devices. Video cameras and even digital cameras are coarser input devices in terms of the resolution of which they are capable, as the chart on page xx makes clear.
