PRB: Device and TrueType Fonts Rotate Inconsistently

 Last reviewed: November 2, 1995
Article ID: Q82932
The information in this article applies to:
  • Microsoft Windows Software Development Kit (SDK) for Windows versions 3.1 and 3.0
  • Microsoft Win32 Application Programming Interface (API) included with: 

        - Microsoft Windows NT versions 3.5 and 3.51
    - Microsoft Windows 95 version 4.0

SYMPTOMS

In an application for the Microsoft Windows graphical environment that uses a mapping mode other than MM_TEXT and a text alignment other than the default (TA_LEFT, TA_TOP), device fonts and TrueType fonts rotate in the opposite directions. Device fonts may exhibit other unusual behaviors. Differences in rotated text may appear on the screen or in printed output.

RESOLUTION

To create a font that rotates based on the coordinate system in which the font is used, the application must set the CLIP_LH_ANGLES (0x10) bit in the lfClipPrecision field of the LOGFONT data structure. This technique is backward-compatible with Windows 3.0 because the CLIP_LH_ANGLES bit is ignored in version 3.0.
