Summary

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

Description

Call this method to get the line spacing, in pixels, of this font. The line spacing 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. Remarks If the font unit is set to anything other than UnitPixel, the height, in pixels, is calculated using the specified vertical resolution. 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
