Bakiki 0 Posted February 15, 2015 Hi Firstly, I realise there in the _ScreenCapture_Capture command but I want to select a section from a jpg file... Then I want to manipuale it in the same enviroment as _GDIPlus_GraphicsFillEllipse. Yes, it's a very newbie question but all the examples scripts I find seem to work with one or the other but not both together... Here is what I've got so far...

UEZ 1,160 Posted February 15, 2015 Two mistakes: 1) $g_hBrush = _GDIPlus_BrushCreateSolid(0xFF0000) -> must be $g_hBrush = _GDIPlus_BrushCreateSolid(0xFF000000) 2) you draw the ellipse in wrong order -> must be just after _GDIPlus_GraphicsDrawImage($g_hGfxCtxt, $g_hBMP, $iX, $iY) ;draw bitmap to backbuffer expandcollapse popup#include <GUIConstantsEx.au3> #include <ScreenCapture.au3> Global $g_hGUI, $g_hGfxCtxt, $g_hBitmap, $g_hBMP, $g_hGraphics Example() Func Example() AutoItSetOption("GUIOnEventMode", 1) _GDIPlus_Startup() ;initialize GDI+ Local Const $iWidth = 600, $iHeight = 600, $iBgColor = 0x303030 ;$iBGColor format RRGGBB $g_hGUI = GUICreate("GDI+ example", $iWidth, $iHeight) ;create a test GUI GUISetBkColor($iBgColor, $g_hGUI) ;set GUI background color GUISetState(@SW_SHOW) ;create buffered graphics frame set for smoother gfx object movements $g_hGraphics = _GDIPlus_GraphicsCreateFromHWND($g_hGUI) ;create a graphics object from a window handle $g_hBitmap = _GDIPlus_BitmapCreateFromGraphics($iWidth, $iHeight, $g_hGraphics) $g_hGfxCtxt = _GDIPlus_ImageGetGraphicsContext($g_hBitmap) Local $iW = 300, $iH = 300 Local $hHBmp = _ScreenCapture_Capture("", 40, 40, $iW, $iH) ;create a GDI bitmap by capturing an area on desktop $g_hBrush = _GDIPlus_BrushCreateSolid(0xFF000000) $g_hBMP = _GDIPlus_BitmapCreateFromHBITMAP($hHBmp) ;convert GDI to GDI+ bitmap _WinAPI_DeleteObject($hHBmp) ;release GDI bitmap resource because not needed anymore Local $iVectorX = Random(1.5, 2.5), $iVectorY = Random(1.5, 2.5) ;define x and y vector Local $iX = 0.0, $iY = 0.0 ;define start coordinate GUISetOnEvent($GUI_EVENT_CLOSE, "_Exit") Do _GDIPlus_GraphicsClear($g_hGfxCtxt, 0xFF000000 + $iBgColor) ;clear bitmap for repaint _GDIPlus_GraphicsDrawImage($g_hGfxCtxt, $g_hBMP, $iX, $iY) ;draw bitmap to backbuffer ;this is what is not working ################# _GDIPlus_GraphicsFillEllipse($g_hGfxCtxt, $iX+50, $iY+50, 30, 30, $g_hBrush) _GDIPlus_GraphicsDrawImageRect($g_hGraphics, $g_hBitmap, 0, 0, $iWidth, $iHeight) ;copy drawn bitmap to graphics handle (GUI) $iX += $iVectorX ;add x vector to current x position $iY += $iVectorY ;add y vector to current y position If $iX < 0 Or $iX > ($iWidth - $iW) Then $iVectorX *= -1 ;when x border is reached reverse x vector If $iY < 0 Or $iY > ($iHeight - $iH) Then $iVectorY *= -1 ;when y border is reached reverse y vector Until Not Sleep(10) ;sleep 10 ms to avoid high cpu usage EndFunc ;==>Example Func _Exit() ;cleanup GDI+ resources _GDIPlus_GraphicsDispose($g_hGfxCtxt) _GDIPlus_GraphicsDispose($g_hGraphics) _GDIPlus_BitmapDispose($g_hBitmap) _GDIPlus_BitmapDispose($g_hBMP) _GDIPlus_Shutdown() GUIDelete($g_hGUI) Exit EndFunc ;==>_Exit Br, UEZ Hide UEZ's signature Hide all signatures Please don't send me any personal message and ask for support!

Bakiki 0 Posted February 15, 2015 Thank you for replying. How can I get a portion of a picture from a jpg file into the variable as oppose to the screen capture. Share this post Link to post Share on other sites
UEZ 1,160 Posted February 15, 2015 1) Load the jpg2) create an empty bitmap in the desired dimension -> _GDIPlus_BitmapCreateFromScan03) copy from the jpg the portion to the empty bitmap using _GDIPlus_GraphicsDrawImageRectRectBr,UEZ Hide UEZ's signature Hide all signatures Please don't send me any personal message and ask for support!
