Dynamsoft TWAIN Products

hi :
i'm using FTPUpload methode with Dynamic web twain 4 :

function Numerise() {
document.forms[0].TwainCon.SelectSource();
document.forms[0].TwainCon.OpenSource();

document.forms[0].TwainCon.FTPPassword = PasswordFTP;
document.forms[0].TwainCon.FTPUserName = UserNameFTP;
document.forms[0].TwainCon.FTPPort = PortFTP;

document.forms[0].TwainCon.TransferMode = 0
document.forms[0].TwainCon.PixelType = 1;
document.forms[0].TwainCon.BitDepth = 8;
document.forms[0].TwainCon.IfShowUI = false;
document.forms[0].TwainCon.EnableSource();
}
function DynamicWebTwain_OnPostTransfer()
{
document.forms[0].TwainCon.DisableSource();
var bool = document.forms[0].TwainCon.FTPUpload( "DevServer", 0 , "test.tiff");
alert("Uploading : " + bool + " Error code : " + document.forms[0].TwainCon.ErrorCode + " Error string : " +document.forms[0].TwainCon.ErrorString );

}



All others FTP parameters are set.
after calling Numerise function, this is result of "alert" function:

Uploading : false Error code : -1002 Error string : Not enough memory to perform operation.


please help me

Hi :
When i remove this two instructions from my code, FTPUpload work well with no problems.

//document.forms[0].TwainCon.PixelType = 1;
//document.forms[0].TwainCon.BitDepth = 8;

only with this two line, the error is rased.

Does this problem always happen after calling Numerise function? If you
upload a very small image file, does this problem also exist?

Would you please save the TIFF file using SaveAsTIFF method and send it to us?

Thanks.
