STRETCH ​

Stretch the positions and sizes when the object's size changes.

Syntax ​

leo-grammar
STRETCH [ on | off ] .

Parameters ​

  • <main-parameter> (modifier, optional) - Turns the stretching of all positions and sizes on or off. The default is on.

Details ​

If an object's size is changed (see resizing), all graphical elements of the object are stretched or compressed geometrically. With the STRETCH command geometric stretching can be switched off (STRETCH off) and back on again (STRETCH on).

Stretching is on by default in a GraphRep.

When stretching is on then all positions and sizes are changed indiscriminately, which can lead to increasing gaps between shapes that should stay the same. It is recommended to also use a TABLE command and base positions / lengths of other commands on its values. This allows for better control over which parts actually change position or size while others can stay fixed, like the size of rounded corners of a ROUNDRECT.

Examples ​

Draw a rectangle with two vertical lines inside of it. The object should be asymmetrically resizable. The left vertical line's position and size should be independent of the object's size. The right vertical line should be stretched and compressed as the object's size changes.
Multiple objects of different sizes, each a rectangle with a sort vertical line 1cm away from the top left corner rectangle

Draw a rectangle with a vertical and a horizontal line inside of it. The object should be asymmetrically resizable. The vertical line should be at the fixed distance of 1.3cm from the left. The horizontal line should split the rectangle with an 4 to 6 ratio (40% above and 60% below).
