zwierzak Posted December 28, 2010 Share Posted December 28, 2010 Hello, I wonder if It's possible to clear particular drawings, withour clearing all of them - it would save some CPU usage while drawing. Redrawing all the lines(even when only few of them change their positions) is pointless. However, I don't know if it's possible. Link to comment Share on other sites More sharing options...
MvGulik Posted December 28, 2010 Share Posted December 28, 2010 Don't think there is a direct way. But if you save your drawing(graphic) you can use that one to undo you next edit/change. (or use it as a general background image.) Suggest you drop some relevant code to show what it is your doing. Might clarify things a bit. Unless its related to your last topic. (is it?)

UEZ Posted December 28, 2010 Share Posted December 28, 2010 That is not possible but you can delete an area of your graphic screen when the object is not intersecting with other objects and the other objects are not moving! It is like writing to a blackboard... Br, UEZ Please don't send me any personal message and ask for support! I will not reply!

zwierzak Posted December 28, 2010 Author Share Posted December 28, 2010 Yes, It's kinda about it. However, I'm asking in gerenal, but u can use that code as well to show me any solution Link to comment Share on other sites More sharing options...
zwierzak Posted December 29, 2010 Author Share Posted December 29, 2010 (edited) I made just as u adviced me to do. But u see, there is one problem. They're flickering far too much. Can u have a look on this example expandcollapse popup#Include <GDIPlus.au3> Opt("GUIOnEventMode", 1) _GDIPlus_Startup() $width = 800 $height = 200 $hGUI = GUICreate("GDI+", $width, $height) $hPen = _GDIPlus_PenCreate(0xFFFF0000) $eSize = 100 $x = $width ;Const $hGraphicConst = _GDIPlus_GraphicsCreateFromHWND($hGUI) $hBitmapConst = _GDIPlus_BitmapCreateFromGraphics($width, $height, $hGraphicConst) $hBackbufferConst = _GDIPlus_ImageGetGraphicsContext($hBitmapConst) _GDIPlus_GraphicsSetSmoothingMode($hBackbufferConst, 2) _GDIPlus_GraphicsDrawLine($hBackbufferConst, 0, 0, 100,50, $hPen) ;Changeable $hGraphic = _GDIPlus_GraphicsCreateFromHWND($hGUI) $hBitmap = _GDIPlus_BitmapCreateFromGraphics($width, $height, $hGraphic) $hBackbuffer = _GDIPlus_ImageGetGraphicsContext($hBitmap) _GDIPlus_GraphicsSetSmoothingMode($hBackbuffer, 2) _GDIPlus_GraphicsClear($hBackbuffer, 0xFFF0F0F0) GUISetState() GUISetOnEvent(-3, "_Exit") While Sleep(40) $pos = MouseGetPos() _GDIPlus_GraphicsClear($hBackbuffer, 0xFFF0F0F0) _GDIPlus_GraphicsDrawLine($hBackbuffer, 0, 0, $pos[0], $pos[1], $hPen) _GDIPlus_GraphicsDrawImageRect($hGraphic, $hBitmap, 0, 0, $width, $height) _GDIPlus_GraphicsDrawImageRect($hGraphicConst, $hBitmapConst, 0, 0, $width, $height) WEnd Func _Exit() _GDIPlus_PenDispose($hPen) _GDIPlus_GraphicsDispose($hBackbuffer) _GDIPlus_BitmapDispose ($hBitmap) _GDIPlus_GraphicsDispose($hGraphic) _GDIPlus_Shutdown() GUIDelete($hGUI) Exit EndFunc Edited December 29, 2010 by zwierzak Link to comment Share on other sites More sharing options...
MvGulik Posted December 29, 2010 Share Posted December 29, 2010 (edited) They're flickering far too much.If your refering to the screen. Drop in a WinSetTrans() after your GUICreate(). (for some older video cards.) $hGUI = GUICreate("GDI+", $width, $height) WinSetTrans($hGUI,"", 255) ;; (255 or -1) If your refering to that odd line thats not doing anything. Drop(disable) that second *_DrawImageRect() line. _GDIPlus_GraphicsDrawImageRect($hGraphicConst, $hBitmapConst, 0, 0, $width, $height)See next msg. GDI+ always good for some ??? with me. (WinSetTrans() trick of course also from UEZ ) Edited December 29, 2010 by MvGulik "Straight_and_Crooked_Thinking" : A "classic guide to ferreting out untruths, half-truths, and other distortions of facts in political and social discussions.""The Secrets of Quantum Physics" : New and excellent 2 part documentary on Quantum Physics by Jim Al-Khalili.

UEZ Posted December 29, 2010 Share Posted December 29, 2010 (edited) Try this: expandcollapse popup#Include <GDIPlus.au3> #include <WindowsConstants.au3> Opt("GUIOnEventMode", 1) Opt("MouseCoordMode", 2) _GDIPlus_Startup() $width = 800 $height = 200 $hGUI = GUICreate("GDI+", $width, $height) $hGUI2 = GUICreate("", $width, $height, -1, -1, $WS_POPUP, $WS_EX_LAYERED + $WS_EX_MDICHILD, $hGUI) GUISetBkColor(0xF0F0F0, $hGUI2) _WinAPI_SetLayeredWindowAttributes($hGUI2, 0xF0F0F0, 0xFF) GUISetState(@SW_SHOW, $hGUI) GUISetState(@SW_SHOW, $hGUI2) $hPen = _GDIPlus_PenCreate(0xFFFF0000) $eSize = 100 $x = $width $hGraphic2 = _GDIPlus_GraphicsCreateFromHWND($hGUI2) _GDIPlus_GraphicsSetSmoothingMode($hGraphic2, 2) _GDIPlus_GraphicsDrawLine($hGraphic2, 0, 0, 100,50, $hPen) ;Changeable $hGraphic = _GDIPlus_GraphicsCreateFromHWND($hGUI) $hBitmap = _GDIPlus_BitmapCreateFromGraphics($width, $height, $hGraphic) $hBackbuffer = _GDIPlus_ImageGetGraphicsContext($hBitmap) _GDIPlus_GraphicsSetSmoothingMode($hBackbuffer, 2) _GDIPlus_GraphicsClear($hBackbuffer, 0xFFF0F0F0) GUISetOnEvent(-3, "_Exit") While Sleep(40) $pos = MouseGetPos() _GDIPlus_GraphicsClear($hBackbuffer, 0xFFF0F0F0) _GDIPlus_GraphicsDrawLine($hBackbuffer, 0, 0, $pos[0], $pos[1], $hPen) _GDIPlus_GraphicsDrawImageRect($hGraphic, $hBitmap, 0, 0, $width, $height) WEnd Func _Exit() _GDIPlus_PenDispose($hPen) _GDIPlus_GraphicsDispose($hBackbuffer) _GDIPlus_BitmapDispose ($hBitmap) _GDIPlus_GraphicsDispose($hGraphic2) _GDIPlus_GraphicsDispose($hGraphic) _GDIPlus_Shutdown() GUIDelete($hGUI2) GUIDelete($hGUI) Exit EndFunc It uses 2 window layers for displaying the graphics. $hGraphic2 is the static one.
