About tscanner and multipage scanner

[toninhofwi]

Hi,

How I can use tscanner with multi file scanner like hp
scanjet 8460 ?

I´m using EZTWAIN 2.70 from dosadi but I can get only one page at a
time, but HP8460 can digitalize 10 pages at a time.

Thanks for any information and best regards,

Toninho.

Hi,
Maybe TwainControlX from http://www.ciansoft.com/ can do the job.
They have a fully functional trial version.

Hi,
Dosadi supports the multipage acquiring without problem.

You only need to update the Dosadi dll and use the TW_AcquireMultiPageFile method of Rafa Carmona's class.

Obviusly you have to use a multipage format like PDF or TIFF.

Hi Marco, thanks.

My dosadi dll was too old. Now I update it.

Thanks a lot and best regards,

Hi

I may have a need for multi page scanning extending the customers current application.

Toninhofwi and George can I ask for the code you used please.

Thanks

Jonathan,
I am not using the Multi-pages scanning features, but the manual explain how to use it.
It seems that Harbour does not support the licensing mechanism of ActiveX controls therefore when ordering TwainControlX send an email to Technical Support (Ian Chester the developer) indicating that your are using Harbour language.
He will send you the TwainControlX which uses a password, set in code, instead of the normal licensing system. That way you don't need the .lic file, you just add a line of code for the password, compile your application, and it will work fine, allowing you install your application along with the registered OCX in your customer's computer.

Regards,

George

Ja resolvi isto
tive que alterar a classe tscan32.
Baixe aqui: http://rapidshare.com/files/164602347/TSCAN.rar.html

Para testar

oScan := TScan32():New( "" )
IF oScan:State() < 4
MSGINFO("Não foi possivel estabelecer a conexão com o scanner. "+CRLF+;
"Verifique se o scanner esta ligado e plugado neste computador.",;
"Procedimento Abortado...")
oScan:End()
RETURN .F.
ENDIF

oScan:PixelType( 1 )
oScan:SetRes( 150 ) // Resolucion 150 by Default.
oScan:SetHide( .T. )
oScan:SetMultiTransfer(1) // escolha 1 para scanear varias paginas
oScan:EnableDuplex(1)
oScan:SetFileFormat(4) ///4
oScan:SetJpegQuality(80) /// 75 default

DO WHILE .T.
nSeqImg++
cImagem:=DIR_TEMP()+"_IMG_"+LIMPO(nSeqImg,.f.)+".JPG"
AADD(aFilesScan,cImagem)
nDib:=(oScan:AcquireToFile(cImagem))
IF nDib < 0
EXIT
ENDIF
syswait(.5)
oScan:FreeDib()
syswait(.3)
ENDDO

oScan:End()

Hi Giovany

Usando eztw32.dll puede ser el más fácil.

Gracias Giovany.

Lo intentaré.
