Scanning to pdf vs tiff

[rgoodson40]

Hello,

I am working on building scanning into my application. I have the application built to handle tifs and pdfs, so I am trying to decide which type to use for scanning. In your opinion, is it better to scan documents as pdf files or tif files? I have used the functionality that you provided in the Twain Scanning Demo application and I can't see much difference between the file types. It does appear that navigating through the pages of a pdf file takes slightly longer, however the compression of pdf files, especially color files, is much better with pdf's than tif's. In other words, pdf files appear to have a much smaller file size than tiffs.

Do you know of any other differences? What would you choose if you had to make this decision?

Thanks,
Reagan

One thing I just thought of is that I am planning to OCR the documents as they come in, so is there a noticeable difference between OCR'ing tiff files versus pdf files? Either with accuracy or the time it takes to run the ocr.

Thank you,
Reagan

Hi;

I have got two process:
1.- Scan documents
scanning to gdpicturepdf object (Put each scaned image, into)
Here user can remove scaned pages, I used a gdpicture thumbnail vievwer

2.- Process ADR & OCR on documents (Receive gdpicturepdf object)
for each page of gdpicturepdf object, i render each image from pdf to image (Put render image id into gdpicture imagining object)
with render image i do ADR & OCR recognition

Problem:
Poor OCR recognition on point, comma, o 0, 6 G, 5 S, etc..
Question:
Will be better don't use gdpicturepdf to store scaned images,
Better use multimage tiff
is there other aproach

Realy i need a orientation

thanks
