float xtd::drawing::font::get_height

(

)

const

Returns the line spacing, in pixels, of this font.

Returns

The line spacing, in pixels, of this font.

Remarks

The line spacing of a xtd::drawing::font is the vertical distance between the base lines of two consecutive lines of text. Thus, the line spacing includes the blank space between lines along with the height of the character itself.

If the unit property of the font is set to anything other than graphics_unit::pixel, the height (in pixels) is calculated using the vertical resolution of the screen display. For example, suppose the font unit is inches and the font size is 0.3. Also suppose that for the corresponding font family, the em-height is 2048 and the line spacing is 2355. For a screen display that has a vertical resolution of 96 dots per inch, you can calculate the height as follows:
2355*(0.3/2048)*96 = 33.11719
