Gets the line spacing of a font in the current unit of a specified Graphics object
#include <GDIPlus.au3>
_GDIPlus_FontGetHeight ( $hFont, $hGraphics )
| $hFont | Pointer to a Font object |
| $hGraphics | Pointer to a Graphics object |
| Success: | the line spacing of this font. |
| Failure: | 0 and sets the @error flag to non-zero, @extended may contain GPSTATUS error code ($GPIP_ERR* see GPIPlusConstants.au3). |
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.
