GraphicalDLL.dll in autoit

[komalo]

hi

is there is a way to use This DLL ( GraphicalDLL ) in autoit

it is written to be used with vb6 but i am trying to use it in an autoit gui

i only need the GPX_BLUR Function so i am trying to convert it to autoit

but i am having lots problems

also , if you know any other Image processing Library ( Not Image Magick nor ProSpeed )

please tell me

that's the GPX_BLUR Source Code

HRESULT __stdcall GPX_Blur (HDC     PicDestDC, 
                            HDC     PicSrcDC,

{
    int BitCount    = 0;
    int Result      = 0;
    int Width       = 0; 
    int Height      = 0;
    BITMAPINFO info;
    HBITMAP PicSrcHwnd = GetBitmapHandle (PicSrcDC, &info, &Width, &Height);

    if (! PicSrcHwnd)

        return (E_FAIL);
    }

    int LineWidth = Width * 3;
    if (LineWidth % 4)
        LineWidth += (4 - LineWidth % 4);

    BitCount = LineWidth * Height;
    LPBYTE Bits = new BYTE[BitCount];

    Result = GetDIBits (PicSrcDC, PicSrcHwnd, 0, Height, Bits, &info, DIB_RGB_COLORS);
    if (Result)
    {
        int i = 0, j = 0, k = 0;
        for (int h = 1; h < Height - 1; h++)

                k = (h - 1) * LineWidth + 3 * w;

                Bits[i+2] = (Bits[i-1] + Bits[j-1] + Bits[k-1] +
                             Bits[i+2] + Bits[j+2] + Bits[k+2] +
                             Bits[i+5] + Bits[j+5] + Bits[k+5]) / 9;

            }

        ::SetDIBitsToDevice (PicDestDC, 0, 0, Width, Height, 0, 0, 0, Height, Bits, &info, 0);
        
        ::DeleteObject (PicSrcHwnd);
        delete [] Bits;

        *Response = (int)Result;
        return (S_OK);
    }

    return (E_FAIL);
}

and here's my code trying to call the dll ( doesn't work )

#include <WinApi.au3>

Dim $Response
GUICreate("aaa")
$Graphic1 = GUICtrlCreatePic("a.bmp",0,0,100,100)
$Graphic2 = GUICtrlCreatePic("a.bmp",200,0,100,100)
GUISetState()

$hwndG1=GUICtrlGetHandle($Graphic1)
$hwndG2=GUICtrlGetHandle($Graphic2)

$SourceDc = _WinAPI_GetDC($hwndG1)
$DestDc = _WinAPI_GetDC($hwndG2)

$Dll = DllCall("GraphicalDLL.dll","Long","GPX_Blur","hwnd",$DestDc,"hwnd",$SourceDc,"int",$Response)

MsgBox("","",$SourceDc&" "& $DestDc)
MsgBox("","",$Response)

_WinAPI_ReleaseDC($hwndG1,$SourceDc)
_WinAPI_ReleaseDC($hwndG2,$DestDc)

_WinAPI_ReleaseDC($hwndG1,$SourceDc)
_WinAPI_ReleaseDC($hwndG2,$DestDc)

You don't say what the error is that you get, but I think

,"int",$Response)

should be

,"int*",$Response)

[komalo]

changed to int_ptr and still got the error

$Dll = DllCall("GraphicalDLL.dll", "Long", "GPX_Blur", "hwnd", $DestDc, "hwnd", $SourceDc, "int_ptr", $Response)

and here's the error message

The instruction at "0x019d6f04" referenced memory at "0x00000000". The memory could not be "written".

Click on OK to terminate the program

Click on CANCEL to debug the program

Any One ?
