    In 2004, Epson introduced their R-D1 (the first digital rangefinder camera on the market), which supports the Leica M mount and Leica M39 mount lenses with an adapter ring. Because its sensor is smaller than that of the standard 35 mm film frame, lenses mounted on the R-D1 have a narrower field of view by a factor of 1.53. In 2006, the R-D1 was ...

For example, there may be a rule that each scan line starts on a particular boundary (such as a byte or word; see for example BMP file format). This means that even otherwise compatible raster data ...
