L_LTEFX_API L_INT L_EfxDraw3dText(hDC, pszText, pRect, uFlags, nXDepth, nYDepth, crText, crShadow, crHilite, hFont, hdcFore)

HDC hDC;	handle to the target device context
L_TCHAR * pszText;	text string
RECT *pRect;	pointer to the display rectangle
L_UINT uFlags;	text style
L_INT nXDepth;	horizontal shadow position
L_INT nYDepth;	vertical shadow position
COLORREF crText;	text color
COLORREF crShadow;	shadow color
COLORREF crHilite;	border color
HFONT hFont;	handle to the selected font
HDC hdcFore;	handle to the device context for foreground

Draws three-dimensional text into the target device context using the specified font, color, and style.

Parameter	Description
hDC	Handle to the target device context.
pszText	Text string.
pRect	Pointer to the display destination rectangle.
uFlags	Text style. Use this parameter to control the style and justification of the three-dimensional text. For valid values, refer to Effect Text Style Flags and Effect Text Alignment Flags.
nXDepth	Horizontal shadow position.
nYDepth	Vertical shadow position.
crText	COLORREF value that specifies the text color.
crShadow	COLORREF value that specifies the shadow color.
crHilite	COLORREF value that specifies the border color.
hFont	Handle to the selected font.
hdcFore	Handle to the source device context for the foreground. Use this parameter to place an image (such as a gradient) on the surface of the three-dimensional text. Use NULL to paint the color specified in crText.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

Use the uFlags parameter to control the style and justification of the three-dimensional text. Use the hdcFore parameter to place an image (such as a gradient) on the surface of the three-dimensional text.

Drop shadows are available only for the following uFlags values:

EFX_TEXT_DROPSHADOW
EFX_TEXT_BLOCKSHADOW
EFX_TEXT_OUTLINEBLOCK

The crShadow color is used for three-dimensional effects for the following uFlags values:

EFX_TEXT_INSETHEAVY
EFX_TEXT_EXTRAHEAVY
EFX_TEXT_RAISEDHEAVY
EFX_TEXT_RAISEDEXTRAHEAVY

The crHilite color is used only for the following uFlags values:

EFX_TEXT_INSETLIGHT
EFX_TEXT_INSETEXTRALIGHT
EFX_TEXT_INSETHEAVY
EFX_TEXT_INSETEXTRAHEAVY
EFX_TEXT_RAISEDLIGHT
EFX_TEXT_RAISEDEXTRALIGHT
EFX_TEXT_RAISEDHEAVY
EFX_TEXT_RAISEDEXTRAHEAVY
EFX_TEXT_OUTLINEBLOCK

Example

This example shows the minimum requirements for using L_EfxDraw3dText.

   HPALETTE  hOurPalette = NULL;     /* The palette that we will use to paint */ 
   L_INT     nBitsPerPixel; 
   /* Get the device context */ 
   hdc = GetDC (hWnd); 
   /* Check the device to see if we need a palette */

   RGB ( 255,255,255 ), /* border color, white */ 
   (HFONT) GetStockObject(SYSTEM_FONT ), 
   NULL );              /* do not put an image in the font */ 
   if(nRet != SUCCESS) 
      return nRet;
