Hilfe bei GDIPlus gesucht

Diggidie

Hallo...

Weiß jemand, wie man eine PNG-Datei auf einer Gui darstellt,
wenn das PNG vorher in einer Variable abgelegt ist?

Das Anzeigen klappt wunderbar, wenn das PNG als Datei vorliegt.
Also z.b. so: (hatte ich irgendwo aus dem Forum her)

$ShowPNG = GUICtrlCreatePic ("", 48, 18)
_Display_PNG ()
GUISetState()

[/autoit] [autoit][/autoit] [autoit]

do
until GUIGetMsg() = $GUI_EVENT_CLOSE

[/autoit] [autoit][/autoit] [autoit]

Func _Display_PNG ()
Local Const $STM_SETIMAGE = 0x0172
_GDIPlus_Startup ()
Local $ImageLoad = _GDIPlus_BitmapCreateFromFile (@ScriptDir & "\Test.png")
Local $ImageHandle = _GDIPlus_BitmapCreateHBITMAPFromBitmap ($ImageLoad)
GUICtrlSendMsg ($ShowPNG, $STM_SETIMAGE, 0, $ImageHandle)
_WinAPI_DeleteObject ($ImageHandle)
_GDIPlus_BitmapDispose ($ImageLoad)
_GDIPlus_Shutdown ()
EndFunc

[/autoit]

Ich lese das PNG aus einem Profil aus (mit _HexRead, hab ich aus dem englischen Forum, wo es eingebettet ist...
Würde mir den Umweg gern ersparen, das PNG erst zu speichern (liegt ja bereits als Variable vor)
und es dann wieder einzulesen...

Müßte doch evtl. mit GDIPlus möglich sein, die Variable direkt zu nutzen... Oder?

Kenne mich mir GDIPlus nicht aus, und wäre über eure Hilfe sehr erfreut..

Hier mal ein lauffähiges Script zum nachvollziehen (benötigt die "TestDatei.7z" aus dem Anhang im Script-Verzeichnis)

;############################################################################################################
;## Schritt 1 = _HexRead extrahiert das PNG aus der Test-Datei und speichert es in der Variable $PNG_Lesen ##
;## Schritt 2 = Das PNG-Bild, also die Variable $PNG_Lesen, wird gespeichert ##
;## Schritt 3 = Das PNG-Bild wird geladen und angezeigt mit _Display_PNG ##
;## Problem = Möchte das speichern und einlesen vermeiden, sondern direkt die Variable $PNG_Lesen nutzen ##

Der Anhang ist keine 7zip Datei, muß also nicht entpackt werden, upload wollte eine Dateiendung haben...
Die angehängte Datei enthält nur 0x00'en und ein eingebettetes PNG-Bild, welches mit _HexRead ausgelesen wird...

Mir geht es nun darum die Variable $PNG_Lesen direkt anzeigen zu lassen,
also ohne den Umweg, wie im Script, mit dem speichern und neu einlesen des PNG...
Der Weg wie im Script mit dem speichern klappt ja, benötige nur dringend eine Variante ohne speichern des PNG...

Schaue mal hier nach, ob du hier fündig wirst: File to Base64 String Code Generator v1.11 Build 2012-10-13

Danke UAZ...
Bekomme Dein Script zwar nicht zum laufen, aber beim durchsehen Deiner Source
bin ich auf die "Load_BMP_From_Mem"-Funktion gestoßen
Funktioniert, aber weiß nicht genau, ob das PNG nach dem anzeigen wieder
aus dem Speicher gelöscht wird... (wie gesagt, kein Plan von GDIPlus)
Könnte mir auch sehr gut vorstellen, das ich überflüssige Dinge mir eingebaut habe
Könnte evtl. jemand das Script mal durchsehen und vielleicht auch dementsprechend anpassen?

Hier das lauffähige Script, wo das PNG aus dem Speicher angezeigt wird, Anhang aus Post 2 wird benötigt...

Das erste Beispiel hier: File to Base64 String Code Generator v1.11 Build 2012-10-13 sollte dir doch weiterhelfen oder?

Nochmals Danke UEZ (Sorry für's A statt dem E vorhin )

Dein erstes Beispiel hat mir die Lösung gebracht... (hoffe ich zumindest)

Hier das fertige Beispiel, sollte so funktionieren... (Anhang aus Post 2 wird benötigt... )

; Function Name: Load_BMP_From_Mem
; Description: Loads an image which is saved as a binary string and converts it to a bitmap or hbitmap
;
; Parameters: $bImage: the binary string which contains any valid image which is supported by GDI+
; Optional: $hHBITMAP: if false a bitmap will be created, if true a hbitmap will be created
;
; Remark: hbitmap format is used generally for GUI internal images, $bitmap is more a GDI+ image format
; Don't forget _GDIPlus_Startup() and _GDIPlus_Shutdown()
;
; Requirement(s): GDIPlus.au3, Memory.au3 and _WinAPI_BitmapCreateDIBFromBitmap() from WinAPIEx.au3
; Return Value(s): Success: handle to bitmap (GDI+ bitmap format) or hbitmap (WinAPI bitmap format),
; Error: 0
; Error codes: 1: $bImage is not a binary string
; 2: unable to create stream on HGlobal
; 3: unable to create bitmap from stream
;
; Author(s): UEZ
; Additional Code: thanks to progandy for the MemGlobalAlloc and tVARIANT lines and

Diggidie

Möchte das Thema nochmal öffnen, weil ich noch eine weitere Funktion benötige, und ein
neues Thema evtl. nicht angebracht wäre...

Wie stelle ich es an, nachdem die Gui aufgebaut ist und die Grafik angezeigt wird, und
ich dann mit dem Mauszeiger über die Grafik fahre, das die Grafik in doppelter Größe
angezeigt wird???

Kurz: Mauszeiger auf Grafik --> Grafik vergrößert sich --> Mauszeiger von Grafik --> Grafik verkleinert sich wieder
(und da kommt bestimmt wieder GDIPlus ins Spiel, wo ich gar nicht durchsteige)

Hier noch mal das Script und die Testdatei:
(Der Anhang ist keine 7zip Datei, muß also nicht entpackt werden, upload wollte eine Dateiendung haben...
Die angehängte Datei enthält nur 0x00'en und ein eingebettetes PNG-Bild, welches mit _HexRead ausgelesen wird...
Kann gern mit einem Hex-Editor überprüft werden...)
