The tick function adds a small cross line marker to a line, of the type often used in geometric diagrams to show that two lines are the same length. They look like this:
You can add 1, 2 or 3 ticks.
tick function
tick(ctx, a, b, count=1, length=4, gap=1)
| Parameter |
Type |
Description |
| ctx |
Context |
The Pycairo Context to draw to |
| a |
(number, number) |
Tuple (x, y) for point a |
| b |
(number, number) |
Tuple (x, y) for point b |
| count |
int |
Number of ticks on the line, 1, 2 or 3. |
| length |
number |
length of the tick in user units. |
| gap |
number |
Gap between ticks in user units. |
Draws an tick across the line ab. The tick is half way between points a and b.
