Comments: |
44 |
|
45 |
All window coordinates behave as follows: |
46 |
- the origin is assumed to be in the top left, so ensure that |
47 |
your templates have this to avoid problems |
48 |
- x coordinates are 0 at the origin and increase across the window |
49 |
- y coordinates are 0 at the origin and increase down the window |
50 |
- scroll offsets are also always positive |
51 |
|
52 |
Coordinates are usually in os units. However, the document classes |
53 |
and fonts use millipoints. At 100%, 400 millipoints = 1 os unit. |
54 |
Font sizes are in 1/16 points. |
