Save Graphic to file without print screen?

[toonboon]

Hi,

Basically the code I have here is the same as monoceres' answer in this topic:

http://www.autoitscript.com/forum/index.php?showtopic=85258

So the following would do.

expandcollapse popup

#include <GDIPlus.au3>

Opt("GuiOnEventMode", 1)
$hwnd = GUICreate("Test", 300, 300)
GUISetState()
GUISetOnEvent(-3, "close")
_GDIPlus_Startup()
$graphics = _GDIPlus_GraphicsCreateFromHWND($hwnd)
$bitmap = _GDIPlus_BitmapCreateFromGraphics(300, 300, $graphics)
$backbuffer = _GDIPlus_ImageGetGraphicsContext($bitmap)
$pen = _GDIPlus_PenCreate(0xFF00FF00, 2)

InetGet("http://msp5.photobucket.com/albums/y196/dannydude182/smiley-300x300.png",@ScriptDir&"\smiley.png")

$image=_GDIPlus_ImageLoadFromFile(@ScriptDir&"\smiley.png")

$matrix = _GDIPlus_MatrixCreate()

_GDIPlus_MatrixTranslate($matrix, 150, 150)



$inc = 0
Do
    _GDIPlus_GraphicsClear($backbuffer)
    
    _GDIPlus_MatrixRotate($matrix,1)
    _GDIPlus_GraphicsSetTransform($backbuffer,$matrix)
    
    _GDIPlus_GraphicsDrawImageRect($backbuffer,$image,-150,-150,300,300)
    
    
    _GDIPlus_GraphicsDrawImageRect($graphics,$bitmap,0,0,300,300)
    Sleep(10)
Until 0


Func close()
    Exit
EndFunc ;==>close


Func _GDIPlus_MatrixTranslate($hMatrix, $nOffsetX, $nOffsetY, $fOrder = True)
    $aResult = DllCall($ghGDIPDll, "int", "GdipTranslateMatrix", "ptr", $hMatrix, "float", $nOffsetX, "float", $nOffsetY, "int", $fOrder)
    If @error Then Return SetError(@error, @extended, False)
    Return SetError($aResult[0], 0, $aResult[0] = 0)
EndFunc ;==>_GDIPlus_MatrixTranslate

What I need to do is find a way to save this 300x300 image the graphic shows to a file, bmp preferredly, so that I can use it for further processing.

I have tried a lot of things but it either crashed or just completely messed up (showed a black 300x300 image when I opened the saved file.)

If anyone could help me out, I'd really appreciate it.

I do not comprehend the question no meter how hard I try

Could you explain once again what exactly you want to do?

Using a hot key "Shift-Alt-s", this script save the image that is on the GUI when the hot key is pressed.
