Linespacing type |
behaviour |
|
LineSpacingType.AtLeast
(Minimum Line Height)
|
Specifies that the height of the line shall be at least the
value specified, but might be expanded to fit its
content as needed. |
|
LineSpacingType.Exactly
(Exact Line Height)
|
Specifies that the height of the line shall be exactly the
value specified, regardless of the size of the contents
of the contents.
If the contents are too large for the specified height,
then they shall be clipped as necessary. |
|
LineSpacingType.Multiple
|
This will multiple the line height with line spacing value.
For example, consider
Type = Multiple
Line height = 10
Line spacing = 2
Than the actual space added between two line is 10 * 2 = 20.
So, if you want to set small value. set line space like 1 or 0.9
