Hi,
ich fange einfach mal so an:
Spoiler anzeigen
#include <GDIPlus.au3>
Opt("GUIOnEventMode", True)
[/autoit] [autoit][/autoit] [autoit]$hWnd = GUICreate("GDI +", 250, 250)
GUISetOnEvent(-3, "_Exit")
GUISetState()
_GDIPlus_Startup()
[/autoit] [autoit][/autoit] [autoit]$hGraphics = _GDIPlus_GraphicsCreateFromHWND($hWnd)
$hBitmap = _GDIPlus_BitmapCreateFromGraphics(250, 250, $hGraphics)
$hBuffer = _GDIPlus_ImageGetGraphicsContext($hBitmap)
$hBrush = _GDIPlus_BrushCreateSolid(0xff0000ff) ;blau
[/autoit] [autoit][/autoit] [autoit]$hPen = _GDIPlus_PenCreate(0xffff00ff, 5) ;pink
$hPen2 = _GDIPlus_PenCreate(0xffff00ff, 5) ;pink
While True
_GDIPlus_GraphicsClear($hBuffer, 0xffffffff)
$iX = Random(0, 250 - 50, 1)
$iY = Random(0, 250 - 50, 1)
_GDIPlus_GraphicsFillRect($hBuffer, $iX, $iY, 50, 50, $hBrush)
_GDIPlus_GraphicsDrawRect($hBuffer, $iX, $iY, 50, 50, $hPen)
_GDIPlus_GraphicsDrawImage($hGraphics, $hBitmap, 0, 0)
Sleep(20)
WEnd
Func _Exit()
Exit
EndFunc
Und jetzt die große Preisfrage... Was fehlt? 
Genau: Das Freigeben der Ressourcen!
Nun, das bedeutet jetzt: Das ganze Skript nochmal durchgehen, und alle geladenen Ressourcen einzeln wieder freigeben.
Das ist mir beim GDI+-Rumspielen so auf den Nerv gegangen (Faulheit! 
), dass ich mir ein Skript geschrieben habe, welches eine Dispose-Funktion erstellt.^^
GDI+ CleanUp.au3
#include <File.au3>
#include <String.au3>
$sFile = $CmdLine[1]
$sDisposeFuncName = "_GDIPlus_DisposeAll"
$sFunctionComment = "Common GDI+ Dispose Function, created with 'GDI+ CleanUp.au3'"
$iReplCounter = 0
Local $aLines[1]
_FileReadToArray($sFile, $aLines)
$sCode = FileRead($sFile)
If StringInStr($sCode, "Func " & $sDisposeFuncName & "()" & @CRLF) Then
$sFunctionCode = _StringBetween($sCode, "Func " & $sDisposeFuncName & "()", "EndFunc")
$sCode = StringReplace($sCode, @CRLF & @CRLF &"Func " & $sDisposeFuncName & "()" & $sFunctionCode[0] & "EndFunc", "")
EndIf
$sExitFuncCode = "Func " & $sDisposeFuncName & "()" & @CRLF & @TAB & ";" & $sFunctionComment & @CRLF
[/autoit] [autoit][/autoit] [autoit]For $iLine = 1 To $aLines[0]
$sLine = StringRegExpReplace($aLines[$iLine], """(.+)""", "", 1)
If Not StringInStr($sLine, "=") Then ContinueLoop ;Keine Ressource wurde erstellt -> Abbruch
[/autoit] [autoit][/autoit] [autoit]$aLR = StringSplit($sLine, "=", 2)
$sVar = StringStripWS($aLR[0], 
$sCommandLine = StringStripWS($aLR[1],
If StringLeft($sCommandLine, 9) <> "_GDIPlus_" Then ContinueLoop ;Keine GDIPlus-Zeile -> Abbruch
$iReplCounter += 1
$aTMP = StringSplit($sCommandLine, "(", 2)
$sCommand = $aTMP[0]
;Bestimmen, welche Art von Ressource vorliegt...
Switch $sCommand
Case "_GDIPlus_GraphicsCreateFromHWND", "_GDIPlus_GraphicsCreateFromHDC", "_GDIPlus_ImageGetGraphicsContext"
;Graphics
$sDisposeCommand = "_GDIPlus_GraphicsDispose"
Case "_GDIPlus_BitmapCreateFromFile", "_GDIPlus_BitmapCreateFromGraphics", "_GDIPlus_BitmapCreateFromHBITMAP", "_GDIPlus_BitmapCreateHBITMAPFromBitmap"
;Bitmaps
$sDisposeCommand = "_GDIPlus_BitmapDispose"
Case "_GDIPlus_ImageLoadFromFile"
;Images

$sDisposeCommand = "_GDIPlus_MatrixDispose"
Case "_GDIPlus_StringFormatCreate"
;StringFormat
$sDisposeCommand = "_GDIPlus_StringFormatDispose"
Case "_GDIPlus_ArrowCapCreate"
;ArrowCaps
$sDisposeCommand = "_GDIPlus_ArrowCapDispose"
Case Else
;Befehl nicht bekannt...
ContinueLoop
EndSwitch
$sExitFuncCode &= @TAB & $sDisposeCommand & "(" & $sVar & ")" & @CRLF
;~ ConsoleWrite("GDIPlus line found @ " & $iLine & " with: " & $sCommand & @CRLF)
Next
$sExitFuncCode &= @TAB & "_GDIPlus_Shutdown()" & @CRLF & "EndFunc"
[/autoit] [autoit][/autoit] [autoit]$sCode &= @CRLF & @CRLF & $sExitFuncCode
[/autoit] [autoit][/autoit] [autoit]$hFile = FileOpen($sFile, 2)
FileWrite($hFile, $sCode)
FileClose($hFile)
ConsoleWrite(StringFormat("+> Es wurden %i Ressourcen verarbeitet.\n+> Dispose-Funktion: %s\n", $iReplCounter, $sDisposeFuncName))
[/autoit]
Bei Gelegenheit könnte man das auch noch auf die WinAPI und DllStruct's erweitern...
Generell ist das ganze noch verbesserungswürdig, aber das kommt noch. Betrachtet es als "Beta".^^
Nach CleanUp
#include <GDIPlus.au3>
Opt("GUIOnEventMode", True)
[/autoit] [autoit][/autoit] [autoit]$hWnd = GUICreate("GDI +", 250, 250)
GUISetOnEvent(-3, "_Exit")
GUISetState()
_GDIPlus_Startup()
[/autoit] [autoit][/autoit] [autoit]$hGraphics = _GDIPlus_GraphicsCreateFromHWND($hWnd)
$hBitmap = _GDIPlus_BitmapCreateFromGraphics(250, 250, $hGraphics)
$hBuffer = _GDIPlus_ImageGetGraphicsContext($hBitmap)
$hBrush = _GDIPlus_BrushCreateSolid(0xff0000ff) ;blau
[/autoit] [autoit][/autoit] [autoit]$hPen = _GDIPlus_PenCreate(0xffff00ff, 5) ;pink
$hPen2 = _GDIPlus_PenCreate(0xffff00ff, 5) ;pink
While True
_GDIPlus_GraphicsClear($hBuffer, 0xffffffff)
$iX = Random(0, 250 - 50, 1)
$iY = Random(0, 250 - 50, 1)
_GDIPlus_GraphicsFillRect($hBuffer, $iX, $iY, 50, 50, $hBrush)
_GDIPlus_GraphicsDrawRect($hBuffer, $iX, $iY, 50, 50, $hPen)
_GDIPlus_GraphicsDrawImage($hGraphics, $hBitmap, 0, 0)
Sleep(20)
WEnd
Func _Exit()
_GDIPlus_DisposeAll()
Exit
EndFunc
Func _GDIPlus_DisposeAll()
;Common GDI+ Dispose Function, created with 'GDI+ CleanUp.au3'
_GDIPlus_GraphicsDispose($hGraphics)
_GDIPlus_BitmapDispose($hBitmap)
_GDIPlus_GraphicsDispose($hBuffer)
_GDIPlus_BrushDispose($hBrush)
_GDIPlus_PenDispose($hPen)
_GDIPlus_PenDispose($hPen2)
_GDIPlus_Shutdown()
EndFunc
Der Dispose-Funktionsname und der Kommentar lassen sich im Skript natürlich anpassen (#ToDo: In INI auslagern und Konfigurationsoberfläche implementieren).^^
Was natürlich noch fehlt:
Die Einbindung in SciTE (Hier ein Danke an BugFix, ohne den wäre ich an dem Lua-Kram gescheitert :D).
SciTEUser.properties
command.name.36.$(au3)=GDI+ CleanUp
command.36.*.au3="$(autoit3dir)\autoit3.exe" "$(SciteDefaultHome)\GDI+ CleanUp.au3" "$(FilePath)"
command.mode.36.*=savebefore:yes
command.shortcut.36.*.au3=Ctrl+Alt+G
Gegebenenfalls dann den Pfad anpassen (Hier würde die Datei im SciTE-Ordner liegen).^^
Have Fun,
chess
