Hello,

I want to use the WIAScanner example so that automatically a tif (instead of jpg) will be created.

It should be possible to set the filename to P for page + pageNumber.

If I scan two pages at once with A3-Scanner it should be possible to automatically increase the pagenumber by 2.

Where and how could this be achieved?

Sincerely

Peter

Hi Peter

The WIAScanner demo does not automatically save the file at all, so you can just use

ImageEnView.IO.SaveToFile( 'D:\MyScan.jpeg' );

To do it automatically after acquiring use the ImageEnView1.AcquireBitmap event.

Thanks for this information. Now I created aprogram for my scanner. When I press ReadParameters button, it is fine. I can see the actual parameters of the scanner. When I change some parameters in the Dialog and press "Write Parameters" I get an error:
Could not convert variant of type Unicodestring into type (Integer).
The same error i receive if I changed nothing in the dialog.


What does "Take New picture' do?

Sincerely

Peter

Hello,
This error is happening if I compile the program.
If I use the original exe "Write Parameters" I get another error: "'Invalid argument" and the parameters are not saved.

I use a Plustek OpticPro A320 Scanner. Scanning is working, but the parameters cannot be changed.

Hi Peter

I cannot reproduce that here.

Have you tried stepping through the code to see where the error is arising.

Hello,

I tried all the examples from Image Acquisition. If I compile them in 32 Bit everything is fine. If I compile then in 64 Bit, my scanner, the Plustek OpticPro A320 is not found.

I installed the Driver for windows 7 64 Bit ultimate.

Sincerely Peter
