Scanner ansprechen

[Donald]

Hi,

hat es schon geschafft einen Scanner von PB aus anzusprechen,
OHNE zusätzliche DLL ?

[bobobo]

twain oder was?

Na bobobo, da haste wohl nicht was überlesen.

Suche ne Möglichkeit ohne zusätzliche DLL.

Die DLL von Andreas kenne ich bereits.

[bobobo]

dann such mal hier http://forums.purebasic.com/english/vie ... ight=twain

oder gar hier http://www.twain.org/

eventuell hilft die Doku oder gar das toolkit

twain ohne dll (oder deren Entsprechungen) ist allerdings wie Atmen ohne Luft oder Denken ohne Hirn.

> Suche ne Möglichkeit ohne zusätzliche DLL.

Wieso? Möchtest Du alles in einer EXE haben? Wenn's keine ActiveX-DLL ist,
dann könntest Du Dir u.U. mal die LoadDllMemory-Lib aus dem PBOSL-Paket
anschauen.

Diese DLL ist publikdomain und ist superklein.
64kb lassen sich überall verstecken und es sind viele Funktionen dabei.
Die Headerdatei erklärt alles was man braucht.
Ich habe heute endlich meine Webcam, mein Pinnacle StudioTV als auch meinen Scanner damit komplett über PB benutzen können.

Viel Spass beim ausprobieren



Ein Wrapper ist leicht mit ts-soft seiner DLL2PBLib erstellt und hier ein Beispiel von
meinem kleinen Testsource in PB4 Beta 6.

Gruß Falko

Code: Alles auswählen

IncludeFile("EZTW32.PB")
EZTW32_Init()
#BitTiefe_0=32
#BitTiefe_1=16
#BitTiefe_2=8
#BitTiefe_3=4

OpenWindow(0, 700, 10, 640, 480,"Test")
CreateGadgetList(WindowID(0))
CreateImage(0,640,480,#BitTiefe_0)
TWAIN_SelectImageSource(hwnd)        ; Gerät auswählen
TWAIN_AcquireToClipboard(0,0)        ; kopiere ins Clipboard
;GetClipboardImage(0)
If StartDrawing(ImageOutput(0))
  DrawingMode(#PB_2DDrawing_Default)
  hbm.l=GetClipboardImage(#PB_Clipboard_Image,#BitTiefe_1)
  ResizeImage(0,640,480)
  If hbm
    DrawImage(hbm,0,0,640,480)
    StopDrawing()
 Else
    Debug "nix im Clipboard"
  EndIf
EndIf

ImageGadget(0,0,0,640,480,ImageID(0))

Repeat
eventID.l = WaitWindowEvent()
Until EventID = #PB_Event_CloseWindow 
  
CloseWindow(0)
EZTW32_End()

Der Wrapper im Frühstadium

Viel Spass beim ausprobieren

Ich hab über den Quelle-Requester herausbekommen, daß mein Scanner als Flachbett Scanner 101.25199 (32-32) identifiziert wird.

Gibt es irgendeinen Weg/eine Funktion, die ich nicht erkenne, mit der ich direkt abfragen kann, ob dieser Scanner an oder aus ist (Rückgabe TRUE oder FALSE) ?
