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.

L_INT EfxDraw3dTextExample(HWND    hWnd,RECT*   pDest) 
{ 
  L_INT nRet; 
  HDC       hdc;                    /* Device context for the current window */ 
  HPALETTE  hSavedPalette = NULL;   /* Temporary copy of the current system palette */ 
  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 */ 
  nBitsPerPixel = GetDeviceCaps( hdc, BITSPIXEL ) * GetDeviceCaps ( hdc, PLANES ); 
  if ( nBitsPerPixel <=8 ) 
  { 
    hOurPalette = (HPALETTE)GetStockObject (DEFAULT_PALETTE); 
    hSavedPalette = SelectPalette (hdc, hOurPalette, FALSE); 
    /* Realize our palette */ 
    RealizePalette (hdc);  
  } 
  /* Draw the 3d Text */

                  TEXT("3D Text - LEADTOOLS"),

                                       /* style flags for 3D Text */ 
                  EFX_TEXT_DROPSHADOW | EFX_TEXT_HCENTER | EFX_TEXT_VCENTER, 
                  2,                   /* horizontal  shadow position */ 
                  2,                   /* vertical shadow position */ 
                  RGB ( 0,0,255 ),     /* text color, blue */ 
                  RGB ( 0,0,0 ),       /* shadow color, black */ 
                  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; 
 
  /* Restore the old palette */ 
  if  ( hOurPalette ) 
    SelectPalette (hdc, hSavedPalette, FALSE); 
  /* Release the device context */ 
  ReleaseDC(hWnd, hdc); 
   return SUCCESS; 
}
