_WinAPI_DrawShadowText UDF: Draw text with a drop shadow

rover · May 15, 2009

DrawShadowText API, An export function of ComCtl32.dll

came across this while reading on MSDN

Minimum OS: Windows XP, ComCtl32.dll version 6 or later

tested on Win XP and Vista

same text formatting and alignment options as _WinAPI_DrawText in helpfile

with addition of text color, shadow color and X/Y shadow offset.

DrawShadowText Function

http://msdn.microsoft.com/en-us/library/bb775639(VS.85).aspx

There are GDI+ drop shadow text examples on the forum that offer more shadow formatting options than this API

the _CreateShadowTextBitmap bitmap text on a background jpg example is not exactly the best implementation...

if the window is hidden, the bitmap is taken from a background window.

more XP drop shadow fun:

Add a drop shadow to native AutoIt GUI Forms and Dialogs

Edit: fixed function header lines wrapping in code boxes
