1.1 root 1: Sample: Demonstration of the Win32 Font API Functions
2:
3: Summary:
4:
5: The NTFONTS sample is an easy to use, powerful utility which
6: allows the user to explore the font system. There is a
7: toolbar on top of the main frame window with buttons that
8: allow the following actions:
9:
10: 1.Enumerate all of the fonts installed for the display.
11: 2.Get TEXTMETRIC & OUTLINETEXTMETRIC information.
12: 3.Create a font based on an arbitrary LOGFONT structure.
13: 4.Get "font data" by using the GetFontData() API.
14: 5.Enumerate all of the fonts available to the default
15: printer.
16:
17: More Information:
18:
19: The program is designed to provide the user an easy
20: interface to the API calls related to the font system. It
21: will not protect against meaningless values, nor will it
22: hide system oddities. Most of the buttons on the toolbar
23: are self explanatory and represent a single system API.
24:
25: Pressing the EnumFonts button will show all of the face
26: names listed horizontally, and each of the fonts within that
27: face name listed vertically below it. TrueType fonts will
28: be marked with a small colored "TT" bitmap. Fonts that have
29: the DEVICE_FONTTYPE bit on will be marked with a small
30: bitmap image of a printer. When the enumeration windows are
31: showing the user can click the left mouse button to copy the
32: information about a selected font into the LOGFONT and
33: TEXTMETRIC dialogs. The user can dismiss this window
34: without changing the dialog boxes by clicking with the right
35: mouse button or typing any character.
36:
37: The "Display" window is able to operate in any one of three
38: modes. These are listed in the "Display" menu. The first
39: just writes "Hello" in the middle of the screen, and it
40: grids the background. This is useful when utilizing the
41: lfEscapement and lfOrientation fields of the LOGFONT structure.
42: The second mode writes all of the glyphs between the tmFirstChar
43: and tmLastChar values stored in the TEXTMETRIC structure. The
44: final mode is used only for true type fonts. It calls
45: GetFontData, finds the 'cmap' table, and displays glyphs from
46: the different ranges in this table. Use the horizontal scroll
47: bar in the display window to step through the ranges.
