What are the common file formats concerning scanning?
All graphic image file formats fall into two categories, either Bitmap formats or Vector formats. Vector formats use mathematical formulas to recreate graphics. If the graphic is a circle, the file format will have the location of the circle’s center, it’s radius and other pertinent information such as what color to draw the circle. Vector formats are easily scalable without creating jagged edges, but they are only suitable for simple drawings with a few colors. Scanners do not use victor file formats. Bitmap formats store the actual color of each dot in the image. They are more suitable for scanned images due to the large number of colors and complex tonal variations in a photograph. A disadvantage to Bitmap formats is that they create large files that take lots of drive space to store. This problem is overcome by several bitmap file formats which compress the data prior to storage on the disk. Most scanning programs use the *.TIF file format as their default. *.TIF files use compress
