Crop HBITMAP?

[Geir1983]

Hi

Is it possible to crop a HBITMAP directly? I got it working by using GDI+ by converting to bitmap, copy wanted part, then convert back to hbitmp.

#include <GDIPlus.au3>
#Include <ScreenCapture.au3>

_GDIPlus_Startup ()

$begin = TimerInit()    ; Test, screenshot direct to hbitmap
Local $hHBMP = _ScreenCapture_Capture('',0,0,@DesktopWidth,@DesktopHeight,False)
ConsoleWrite("Creating _ScreenCapture_Capture hbitmap Desktop screenshot took " & TimerDiff($begin) & " milliseconds"& @LF)

$begin = TimerInit()    ; Test, Crop from hbitmap
Local $hBMP= _GDIPlus_BitmapCreateFromHBITMAP($hHBMP)
Local $hBMP_Cropped = _GDIPlus_BitmapCloneArea($hBMP, 0, 0, 110, 110)
Local $hHBMP_Cropped = _GDIPlus_BitmapCreateHBITMAPFromBitmap($hBMP_Cropped)
;_GDIPlus_ImageSaveToFile($hBMP_Cropped, $BMP3)
ConsoleWrite("Creating cropped hbitmap Desktop screenshot took " & TimerDiff($begin) & " milliseconds"& @LF)

Maybe

_ScreenCapture_Capture(@ScriptDir & "\Cropped.jpg", 0,0,110, 110,False)

No, you misunderstand. I want to create a "master" screenshot, directly to hbitmap. Later in my program i will use different parts from the master screenshot. The line with save cropped image to file was just for debug.

Edit; my example does what i want, but is it neccessary to convert hbitmap to bitmap to do cropping?

It should be possible to crop with GDI but I assume it is much more complicated to do it rather with the method you have posted.
 
Why you are converting it back to HBitmap ($hHBMP_Cropped) again?

Ok ill just stick with that method then. I thought it might be an faster way to do it. I convert back to hbitmap because that is the input for other functions i use.
