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 information.
12: 3.Create a font based on an arbitrary LOGFONT structure.
13: 4.Enumerate all of the fonts available to the default
14: printer.
15:
16: More Information:
17:
18: The program is designed to provide the user an easy
19: interface to the API calls related to the font system. It
20: will not protect against meaningless values, nor will it
21: hide system oddities. Most of the buttons on the toolbar
22: are self explanatory and represent a single system API.
23:
24: Pressing the EnumFonts button will show all of the face
25: names listed horizontally, and each of the fonts within that
26: face name listed vertically below it. TrueType, or any
27: other fonts that do not have a type of RASTER_FONTTYPE 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: There are two check boxes on the toolbar. "ShowAllGlyphs"
38: toggles between painting the "TextOut" window with all of
39: the font's glyphs (from TEXTMETRIC.tmFirstChar to
40: TEXTMETRIC.tmLastChar) and writing a shorter string in the
41: middle of the window. This latter case is prefered when
42: rotating the font, or when writing in directions other than
43: left to right. The "SetMapperFlags" check box simply
44: maintains a boolean state. This is set into the HPS just
45: before the logical font is created for repainting, c.f.
46: SetMapperFlags function.
