Hello,

i think that :
GetLineHeight would probably be tm.tmHeight + tm.tmExternalLeading not tm.tmHeight + tm.tmInternalLeading + tm.tmExternalLeading

tmInternalLeading
Specifies the amount of leading (space) INSIDE the bounds set by the tmHeight member. Accent marks and other diacritical characters may occur in this area. The designer may set this member to zero.

so when you add tm.tmInternalLeading it is counted two times.
