How to create modified _ScreenCapture_CaptureWnd() (help request for experts)

10 posts in this topic

#1 ·  Posted (edited)

See my last reply.

How can I create modified version of _ScreenCapture_CaptureWnd(). I want modify that function so instead of saving image to file it would return image.I know how find the ScreenCapture.au3, but I don't know how and what I need to modify.In ScreenCapture.au3 function _ScreenCapture_CaptureWnd() call next functions, and those call next ones, and so on, also there are many commands, functions that I haven't used yet, so I have no experience with these commands.

I need to create _ScreenCapture_CaptureWnd() that returns binary string (it can also be hex code it doesn't matter) instead of saving image.Most important thing is that I need _ScreenCapture_CaptureWnd() that returns image, it must not save image to disk.

I also need function to display image in GUI.As we all know GUICtrlCreatePic() requires file,But I need special function that loads image from binary string.

Idea is that if I don't save image to hard disk, I don't have to waste time on writing image disk, and then reading it from disk.If I need to update image of window in my GUI about 10 times/sec, Hard disk must do lot's of work.That's the reason why I need CaptureScreen function that returns image as string,and _GuiCtrlCreateX function that loads image to GUI picture control with out saving it to hard disk.

If you know how to do that or if u can suggest me what to edit in original functions, please let me know.

Thanks.

Look here for executefrommem using the binary form of the image file.

About _ScreenCapture_CaptureWnd(), if you'll specify a blank string in the first parameter you'll get a bitmap handle instead of saving it to a file. Read the function parameter explanations.

How I get image from handle?

screenshot ends with code that I don't understand well.

$aResult = DllCall($ghGDIPDll, "int", "GdipSaveImageToFile", "hwnd", $hImage, "wstr", $sFileName, "ptr", $pGUID, "ptr", $pParams)

thanks Zenda, But I still need function to get string from image's handle, How I do that?

_ScreenCapture_CaptureWnd() returns handle, but handle is not enough, I need my string!

There may be a few commands in this script you have no used before.

Your requirement of 10 screen captures per second intrigued me. I didn't think it could be done with _ScreenCapture_Capture().

The bigger the screen capture, the less number of screen captures per second.

With a capture size of 600x500, this script displays to a GUI in less than 0.100 secs most of the time.

another example i prefer:

you have to replace the "Editor" in WinGetHandle with your wintitle and this is just a test script, you have to release the resources of the gdi funcs too :)

#NoTrayIcon
#include <GUIConstantsEx.au3>
#include <ScreenCapture.au3>
#include <GDIPlus.au3>

$guiMain = GUICreate("Test Window", 402, 306, 810, 423)
$guiPic = GUICtrlCreatePic("", 8, 8, 385, 289)
GUISetState(@SW_SHOW)

_GDIPlus_Startup()

$hWnd = WinGetHandle("Editor") ; <- type the window title you want to capture here
$hBitmap = _ScreenCapture_CaptureWnd("",$hWnd)
$hImage = _GDIPlus_BitmapCreateFromHBITMAP ($hBitmap)
$iX = _GDIPlus_ImageGetWidth ($hImage)
$iY = _GDIPlus_ImageGetHeight ($hImage)
$hBitmap2 = _GDIPlus_BitmapCloneArea($hImage, 0, 0, $iX, $iY, $GDIP_PXF24RGB)
$hHBitmap = _GDIPlus_BitmapCreateHBITMAPFromBitmap($hBitmap2)

_SetBitmapToCtrl($guiPic, $hHBitmap)

While 1
    If GUIGetMsg() = $GUI_EVENT_CLOSE Then Exit
    Sleep(10)
WEnd

Func _SetBitmapToCtrl($CtrlId, $hBitmap) ;function by Zedna
    Local Const $STM_SETIMAGE = 0x0172
    Local Const $IMAGE_BITMAP = 0
    Local Const $SS_BITMAP = 0xE
    Local Const $GWL_STYLE = -16

    Local $hWnd = GUICtrlGetHandle($CtrlId)
    If $hWnd = 0 Then Return SetError(1, 0, 0)
    
    ; set SS_BITMAP style to control
    Local $oldStyle = _WinAPI_GetWindowLong($hWnd, $GWL_STYLE)
    If @error Then Return SetError(2, 0, 0)
    _WinAPI_SetWindowLong($hWnd, $GWL_STYLE, BitOR($oldStyle, $SS_BITMAP))
    If @error Then Return SetError(3, 0, 0)
    
    Local $oldBmp = _SendMessage($hWnd, $STM_SETIMAGE, $IMAGE_BITMAP, $hBitmap)
    If @error Then Return SetError(4, 0, 0)
    If $oldBmp <> 0 Then _WinAPI_DeleteObject($oldBmp)
    Return 1
EndFunc

Malkey your source is close to my needs but I want to change it's working method.

1)it must return binary string from picture, I should look like this:

Pic:

String:

Malkey your source is close to my needs but I want to change it's working method.

1)it must return binary string from picture, I should look like this:

Pic:

.....

String:

.........

2)when function get string like above and PicControl ID as arguments , it must draw pic from string.

A possible direction for you is at

http://www.autoitscript.com/forum/index.ph...st&p=681193

or

http://www.autoitscript.com/forum/index.ph...st&p=663576

_GDIPlus_BitmapLockBits() lets you access all the pixels in a continuous BBGGRRAA hex colour format with DllStructGetData(Data Structure, 1)

If you change or replace the returned "0x89504EFF470D0AFF1A0A00FF44..." type string, DllStructSetData(Data Structure, 1, Different String Data) will replace the original string data.

Then call _GDIPlus_BitmapUnlockBits() which allows access to the modified bitmap.

There may be other better ways.
