VintaSoft Twain .NET SDK Discussions

Hello,

it is great that we now have the possibility do swap images in the internal buffer. What we also need now would be a possibility to add images to the internal buffer so that we can exchange 'bad' scans by subsequent scans doing a rescan of the bad page (repeatly using the Aquire Method) and using the Deleteimage and Swapimages methods to reoder the pages. So we could save the internal buffer to a multipage pdf file and have the pages still in the right order. I did not find a way of doing that because each subsequent call of the Aquire method deletes/clears the internal buffer.

Is there any way I overlooked or - if not - could it be possible to implement a Aquire method which does not clear the internal buffer ?

Thank you, Alexander,

this is exactly what I was looking for. It works as expected.

Hello Michael,

Why you need so big buffer?

Best regards, Alexander

VintaSoftTwain.NET Library allows to add images to existing TIFF file or PDF document. I think the best way is
to use this functionality.
Are you sure that you will not have "Out of memory" exception if you store 1000 A4 images in the buffer?

Best regards, Alexander

Hello,
our users need to scan documents and save them as PDF multipage. However, in some situation, they need to temporary save scanned documents (for example as jpeg images) to be retrieved in the following days, then do some image adjustment (using the despeckle, deskew and rotation features) and save images as PDF multipage.

Do you have any solution for this?

We think that we could solve our problem having the possibility to add images to the internal buffer of VSTwain object.

Best Regards,
Carl.
