Using TopOCR's Scan to PDF Feature
TopOCR allows you to save all of the open images displayed in Topocr's Image Window as a single PDF image file.
This gives you the ability to create a PDF "book" by simply scanning a stack of images, and then when you're finished scanning, use the File->SaveAll function to save them in PDF image format.
The type of image compression the File->SaveAll function uses is dependent on the pixel depth of the image.
Reading PDF Files
When you open a multi-page PDF file in TopOCR, it will display the first page, you can then use the Page->Next, Page->Previous, Page->First, Page->Last commands to navigate to other pages within the document.
If you want to extract the text for any particular individual page, just press the [OCR] button.
If instead you would prefer to automatically extract ALL of the text from the multi-page PDF document as soon as you open the document, then simply turn the Settings->Auto-OCR On/Off command to "On" before you open the multi-page PDF document and TopOCR will extract all of the text, page-by-page into the text window.
For the best results reading PDF files, we recommend operating TopOCR in "Scanner Mode", by changing the Settings->OCR->Binarization Type to Scanner. In this mode, TopOCR OCR can OCR the pages in a multi-page PDF document at 10+ pages per second on a high-end PC.
PDF to MP3 Conversion
Once TopOCR has extracted all the text from your PDF file and placed it in the Text Window, you can press the Text Windows's TextToSpeech command and turn the text into an MP3 file.
Merging PDF Files
Now you can partially scan a book and later combine the pdf files together, thanks to a simple utility called PDFBinder. After you download and install this easy to use utility, simply drag and drop the pdf files in the order they're to be merged onto PDFBinder, and when you've finished, click on the Bind! button and PDFBinder will merge all the separate PDF input files into one PDF output file.
