Creating a Logical Font with a Nonzero lfOrientation

Q104010



The information in this article applies to:


  • Microsoft Win32 Application Programming Interface (API), included with:
    • the operating system: Microsoft Windows NT, versions 3.1, 3.5, 3.51





SUMMARY

To create a font that writes in a direction other than left to right, an application should specify a nonzero lfEscapement in the LOGFONT structure that is passed to CreateFontIndirect(). This method works under Windows NT regardless of the graphics mode of the device context.

To create a font where the characters themselves are rotated, the application should specify a nonzero lfOrientation in the LOGFONT structure that is passed to CreateFontIndirect(). However, this setting is ignored in Windows NT unless the graphics mode is set to GM_ADVANCED.

Therefore, to successfully create a logical font with a nonzero lfOrientation, use

SetGraphicsMode( hDC, GM_ADVANCED )

to set the graphics mode of the device context to GM_ADVANCED.



MORE INFORMATION

The TTFONTS sample program is a good way to quickly and easily see the effects of the lfEscapement and lfOrientation fields. However, TTFONTS does not set the graphics mode of its test window HDC to GM_ADVANCED. As a result, the lfOrientation field apparently is ignored. It is easy to modify the DISPLAY.C module of TTFONTS in order to set the graphics mode of the window HDC to GM_ADVANCED.
