41 | // CSS specification offer following guidance on dealing with pixel sizes | |
42 | // when printing at | |
43 | // http://www.w3.org/TR/2004/CR-CSS21-20040225/syndata.html#length-units: | |
44 | // | |
45 | // Pixel units are relative to the resolution of the viewing device, i.e., | |
46 | // most often a computer display. If the pixel density of the output | |
47 | // device is very different from that of a typical computer display, the | |
48 | // user agent should rescale pixel values. It is recommended that the [ | |
49 | // reference pixel] be the visual angle of one pixel on a device with a | |
50 | // pixel density of 96dpi and a distance from the reader of an arm's | |
51 | // length. For a nominal arm's length of 28 inches, the visual angle is | |
52 | // therefore about 0.0213 degrees. | |
53 | // | |
54 | // For reading at arm's length, 1px thus corresponds to about 0.26 mm | |
55 | // (1/96 inch). When printed on a laser printer, meant for reading at a | |
56 | // little less than arm's length (55 cm, 21 inches), 1px is about 0.20 mm. | |
57 | // On a 300 dots-per-inch (dpi) printer, that may be rounded up to 3 dots | |
58 | // (0.25 mm); on a 600 dpi printer, it can be rounded to 5 dots. | |
