_WinAPI_DrawBitmap

Draws a bitmap into the specified device context

#include <WinAPIGdi.au3>
_WinAPI_DrawBitmap ( $hDC, $iX, $iY, $hBitmap [, $iRop = 0x00CC0020] )

Parameters

$hDC Handle to the device context into which the bitmap will be drawn.
$iX Specifies the logical x-coordinate of the upper-left corner of the bitmap.
$iY Specifies the logical y-coordinate of the upper-left corner of the bitmap.
$hBitmap Handle to the bitmap to be drawn.
$iRop [optional] The raster-operation code (same as for _WinAPI_BitBlt()). Default is $SRCCOPY.

Return Value

Success: 1.
Failure: 0 and sets the @error flag to non-zero.

Remarks

This function does not support bitmaps with alpha channel, use _WinAPI_AlphaBlend() to work with them.
