Error with TWAIN_AcquireImage and getMultiple #38

Open AlfonsoIdem opened 5 years ago

Hi,

With 4D v17R6 (last) and windows 10 - 64 bits. Fujitsu fi-800R (Duplex) Driver for fujitsu fi-800R (32 bits) : PaperStream IP fi-800R If I scan normal (no duplex) $lErr:=TWAIN_AcquireImage (1;””;0;0;0) it's work fine. Scannig with the command TWAIN_AcquireImage as your example (Duplex): After executeed $lErr:=TWAIN_AcquireImage (1;””;0;1;0) Windows create a message error that I can not see, and freeze the scan process. I have to kill the procces (TWAIN_AcquireImage , in the system) for 4D continue.

It's a problem with driver ? Any solution ?

T.I.A.

I have try also your example:

ARRAY PICTURE($agPics;0) While ($lOffSet<BLOB size(xTWAINBLOB)) BLOB TO VARIABLE(xTWAINBLOB;$xBlob;$lOffset) BLOB TO PICTURE($xBlob;gPic) $f:=Picture size($gPic) SET PICTURE TO PASTEBOARD($gPic) APPEND TO ARRAY($agPics;$gPic)

        End while

And it doesn't work In the line: BLOB TO VARIABLE(xTWAINBLOB;$xBlob;$lOffset) OK get 0

T.I.A.

At time of execute $lErr:=TWAIN_AcquireImage (1;””;0;0;0). The scanner scan the document but 4D freeze waiting for an answer by the plugin. I have observed in Administration tasks, that a process named Orchad Utilities(32 bits) is waiting for someting. But I could not see any window message. If I Kill this process in Windows System then 4D continuous with the process and I get the 2 images OK. Are you aware about this problem ?
