Marcus Meissner | 0546a76 | 2012-04-10 18:49:10 +0200 | [diff] [blame] | 1464 | The idea is to simply 'condense' these values to just one uint16 to be able to conveniently |
Linus Walleij | 1a0c301 | 2009-07-23 23:06:58 +0000 | [diff] [blame] | 1465 | use the available enumeration facilities (look-up table). The image size and compression |
| 1466 | values fully describe the image format. Hence we generate a uint16 with the four nibles set |
| 1467 | as follows: entry 1 size | entry 1 compression | entry 2 size | entry 2 compression. |
| 1468 | The above example would result in the value 0x1400. |
