Targets: MS-DOS, Win32
Graph Unit
Returns the height of a string, in pixels.
Declaration:
function TextHeight(TextString: string): DWORD;
Remarks:
Takes the current font size, and determines the height of the
TextString in pixels. This is useful for adjusting the
spacing between lines, computing viewport heights,
sizing a title to make it fit on a graph or in a box, etc.
It is important to use TextHeight to compute the height of strings,
instead of doing the computation manually.
In that way, no source code modifications have to be made when different
fonts are selected.
