Configuring scanner options?

Post by wbrells » Fri Jun 23, 2017 7:11 pm

I've been testing the option of creating a PDF document via scanning. The basic process seems to work, but I'm concerned that there doesn't seem any way to control scanner options such as resolution, color/B&W mode, image brightness/contrast, etc. The default appears to be for scanning in color, which isn't really appropriate for b&w text documents. Probably as a result of this default, text documents come out with an unattractive gray background (and are, I imagine, much larger than necessary).

Does anyone know if there is way of adjusting scanner parameters? (I'm using a Canon 8800F flatbed scanner, in case that matters).

Many thanks!

Are you trying to scan via TWAIN or WIA?

I'm using the WIA interface. For some reason the TWAIN interface gives an error message saying that the program cannot communicate with the scanner...

It would certainly seem more flexible if FlexiPDF could be used to OCR a file that had been previously scanned by some other program. Is this a feature that is likely to be available at some point?

Thanks,
Wayne

SORRY - I just recalled that OCRing of (for example) a JPG file is available, but the problem with that approach is there doesn't appear any way in FlexiPDF to straighten/cleanup the image before OCRing it. I gather that the scanner approach in FlexiPDF will do such straightening, etc., which is what initially prompted my question about scanner options. The bottom line is that FlexiPDF needs an option to straighten/cleanup a file before it is OCRed... (Perhaps this option is available, but I haven't been able to find it!)

According to the developers:
Our OCR mechanism will straighten scanned objects.

We've tested it on a document where the image is rotated by around 7-9 degrees and it did straighten the resulting objects.

If the resulting objects do not get straightened by our OCR mechanism, you can use the "Obeject Select" (Arrow) tool to select the object and then use the "Rotate" tool to rotate the image before using the OCR mechanism.

I've done a bit a testing and found that the OCR option does, indeed, straighten an image. Unfortunately, as can be seen in the attached PDF file, the "corrected" image appears on a gray background canvas - not very attractive. I do not see this behavior with Adobe Acrobat - please see the two attached PDF files for a comparison.... Wayne

I don't see the original question answered yet. Thus, is there a way of adjusting scanner parameters?

Yes, but have to make sure to use TWAIN, not WIA.
