This function succeeds only with TrueType fonts. Syntax BOOL GetCharABCWidths( __in HDC hdc, __in UINT uFirstChar, __in UINT uLastChar, __out LPABC lpabc ); Parameters hdc [in] A handle to the device context. uFirstChar [in] The first character in the group of consecutive characters from the current font. uLastChar [in] The last character in the group of consecutive characters from the current font. lpabc [out] A pointer to an array of ABC structures that receives the character widths, in logical units. This array must contain at least as many ABC structures as there are characters in the range specified by the uFirstChar and uLastChar parameters. Return Value If the function succeeds, the return value is nonzero If the function fails, the return value is zero. Remarks The TrueType rasterizer provides ABC character spacing after a specific point size has been selected. A spacing is the distance added to the current position before placing the glyph. B spacing is the width of the black part of the glyph. C spacing is the distance added to the current position to provide white space to the right of the glyph. The total advanced width is specified by A+B+C. When the GetCharABCWidths function retrieves negative A or C widths for a character, that character includes underhangs or overhangs. To convert the ABC widths to font design units, an application should use the value stored in the otmEMSquare member of a OUTLINETEXTMETRIC structure. This value can be retrieved by calling the GetOutlineTextMetrics function. The ABC widths of the default character are used for characters outside the range of the currently selected font. To retrieve the widths of characters in non-TrueType fonts, applications should use the GetCharWidth function.
