// Description:

sl@0
|
14 |
// Converts logical coordinate value to physical coordinate value.
|
|
sl@0
|
15 |
// Then adjusts the value, assuming that it must be within the drawing rectangle.
|
|
sl@0
|
16 |
// The first, "<0" check is arguable - should it be there or not!?
|
|
sl@0
|
17 |
// Because it HIDES negative values of "x" coordinate, so possible programmer's errors!
|
|
sl@0
|
18 |
// But with used logical to physical transformation it is possible that some logical
|
|
sl@0
|
19 |
// coordinate value might be transformed to negative physical coordinate value and
|
|
sl@0
|
20 |
// then it has to be checked and set to 0.
