get_height() [3/3]

float xtd::drawing::font::get_height

(

float

dpi

)

const

Returns the height, in pixels, of this Font when drawn to a device with the specified vertical resolution.

Parameters

dpi	The vertical resolution, in dots per inch, used to calculate the height of the font.

Returns

The height, in pixels, of this xtd::drawing::font.

Remarks

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. If the specified vertical resolution is 96 dots per inch, the height is calculated as follows:
2355*(0.3/2048)*96 = 33.1171875
