  1. Hello again the AutoIt Forums! I've gotten really addicted to the GDIPlus stuff and I'm trying to do more. Trying to create small editor using GDIPlus and I'm a bit lost just getting started. The main GUI is small, so when I you Snip an area that's larger than the GUI it would only display as large as the GUI (I got around this by setting an event for WM_WINDOWPOSCHANGING but it flickers really badly). I tried doing something by setting the bitmap to a GUICtrlCreatePic control but it still flickered. So essentially I need a way to create a graphics larger than the GUI itself and I don't know how to do something like that. I thought it would have been _GDIPlus_GraphicsCreateFromHDC but it still wasn't create it properly. I did a lot of googling and this topic has a lot of great info in it and I will probably incorporate scrollbars too, later, but UEZ didn't give the secret to resizing! Lol I've got the source code for vPaint downloaded, and I've started to through some of it (But like the author said, the source code is messy and things are out of order) so it may take a while. #include <GDIPlus.au3> #include <File.au3> #include <GUIConstants.au3> #include <String.au3> #include <GuiConstantsEx.au3> #include <WinAPI.au3> #include <WindowsConstants.au3> #include <ScreenCapture.au3> #include <Color.au3> #include <Misc.au3> #include <WinAPISys.au3> #include <GuiToolbar.au3> #include <GuiImageList.au3> #include <Array.au3> AutoItSetOption("GuiOnEventMode", 1) AutoItSetOption("MustDeclareVars", 1) HotKeySet("{Esc}", "ClosePixShop") Global $frm_pixshop_abscoord[4] = [100, 100, 400, 200] Global $frmPixShop Global $tlbPixShopToolbar Global $hWnd_toolbar_image_list Global $hWnd_dll = DllOpen("user32.dll") Global $frm_pixshop_state = @SW_HIDE Global $hWnd_bitmaps[1] Global $picBitmaps[1] Global $abscoord_bitmaps[1][2] = [[0, 0]] Global $abscoord_graphics[4] = [8, 46, 0, 0] Global $pixshop_buffer[1] Global Enum $idToolbarStart = 1000, $idMouse, $idSnip, $idCrop, $idText, $idBrush, $idToolbarEnd Global $hWnd_pixshop_graphics Global $hWnd_pixshop_bitmap Global $hWnd_pixshop_buffer PixShop() Func PixShop() $frmPixShop = GUICreate("PixShop", $frm_pixshop_abscoord[2], $frm_pixshop_abscoord[3], $frm_pixshop_abscoord[0], $frm_pixshop_abscoord[1], $WS_SIZEBOX, $WS_EX_TOPMOST) $tlbPixShopToolbar = _GUICtrlToolbar_Create($frmPixShop, $TBSTYLE_TRANSPARENT) GUICtrlCreateLabel("", 0, 36, $frm_pixshop_abscoord[2], $frm_pixshop_abscoord[3], -1, $WS_EX_LAYERED) GUICtrlSetBkColor(-1, 0x0D0D0D) GUICtrlSetResizing(-1, $GUI_DOCKLEFT + $GUI_DOCKTOP + $GUI_DOCKRIGHT + $GUI_DOCKBOTTOM) GUISetBkColor(0x535353, $frmPixShop) $hWnd_toolbar_image_list = _GUIImageList_Create(24, 24, 5, 5) _GUIImageList_AddIcon($hWnd_toolbar_image_list, @ScriptDir & "\Icons\Mouse.ico") _GUIImageList_AddIcon($hWnd_toolbar_image_list, @ScriptDir & "\Icons\Snip.ico") _GUIImageList_AddIcon($hWnd_toolbar_image_list, @ScriptDir & "\Icons\Crop.ico") _GUIImageList_AddIcon($hWnd_toolbar_image_list, @ScriptDir & "\Icons\Text.ico") _GUIImageList_AddIcon($hWnd_toolbar_image_list, @ScriptDir & "\Icons\Brush.ico") _GUICtrlToolbar_SetImageList($tlbPixShopToolbar, $hWnd_toolbar_image_list) _GUICtrlToolbar_SetIndent($tlbPixShopToolbar, 2) _GUICtrlToolbar_AddButton($tlbPixShopToolbar, $idMouse, 0) _GUICtrlToolbar_AddButton($tlbPixShopToolbar, $idSnip, 1) _GUICtrlToolbar_AddButton($tlbPixShopToolbar, $idCrop, 2) _GUICtrlToolbar_AddButton($tlbPixShopToolbar, $idText, 3) _GUICtrlToolbar_AddButton($tlbPixShopToolbar, $idBrush, 4) _GUICtrlToolbar_SetColorScheme($tlbPixShopToolbar, 0x535353, 0x535353) _GUICtrlToolbar_CheckButton($tlbPixShopToolbar, $idMouse, True) GUISetOnEvent($GUI_EVENT_CLOSE, "ClosePixShop") ;
