BatchScanPlus supports TWAIN-Compliant devices, such as scanners and digital cameras.
To select a TWAIN-compliant device for acquiring images:
The Sources window displays the names of the TWAIN-compliant
devices connected to your computer.
Highlight the device that you want to use.
Click Select to close the dialog box.
Use the Scanner Data Source interface (it will be different
for each scanner) to set the image acquisition options.
When the device and its software finish processing the image, the image is sent to BatchScanPlus
The Scanner Data Source dialog box remains open even
after the image is loaded into BatchScanPlus.
If Process and Save automatically is selected, you can continue to scan images and close it after you have finished.
If Process and Save automatically is NOT selected, images will not be saved automatically, therefore if scanning several images, each new scan will overwrite the previous one without saving it.
Process and Save automatically. This option should be left selected most of the time. When selected, images will be rotated, cropped and rotated, following the settings below, and also saved automatically. In this way it is not needed to close the Scanner Data Source dialog box until all files are scanned.
Remove Noise: When this option is selected black and white and grayscale images will be processed to eliminate the noise.
Ask before overwriting files: If this option is deselected, files already existent in the same folder, may be overwritten without any warning, if its names are the same that the new files being saved. When selected, a warning message will ask the user if he wants to overwrite the file.
Image Format: BatchScan Pro can save images as BMP, PNG or JPG files. PNG is the preferred image file format, because it is lossless, and compressed. BMP files are big, but do not lose any quality. JPEG files are the smaller ones, but lose more or less quality, depending on the JPEG compression selected when saving Images or in the Preferences windows.
Rotation: Usually, for single pages, rotation is 0 degrees, but both single and double pages scans can be rotated 90,180 or 270 degrees.
Rotation to: Rotation can be applied to All Pages, Only odd pages
or Only even pages.
Since a larger book has to be turned to fit a scanner when using an A4 scanner, sometimes it may be handy rotating only every other page.
Split Pages in two files: Select this option when scanning a two pages spread each. In that way image will be automatically divided in two and saved as two different files, each one with a different page number.
Rotate 180° after splitting. This option only will be enabled when Split Pages in two files is selected. It is only used when scanning books with right to left page sequence (like traditional Chinese books).
Canvas Size: This option is used to equalize all pictures to the
same width and height. Of course, if when scanning always exactly the
same page area (or the full page are), setting the Canvas size is not
If images are too small or text is too close to the margins, when reducing the Canvas size text can be lost if the settings are not adequate.
Page Number: When scanning images, files will be saved automatically into the selected folder. The file names will be composed by a number plus the Image Format file extension selected. The first scan will be saved with the specified Page number, each scan will have an increased file number. Example: 001.png, 002.png, etc.
Digits: this value determines how many zeros will be inserted to
make the file name at least # digits long.
Example: if the last page is number 80, 2 is a good value, because no number will have more than 2 digits.
If any character is typed in this text box, it will be appended
in front of the file name. As an example c:\files\003.png
would become c:\files\.003.png
if the character . (period punctuation mark) was written in the
Prefix text box.
This option is useful when a book has roman numeration for the first pages. Because the book pages always will be saved as files with names with arabic numeration (001, 002, etc.), having a set of pages with roman numeration would cause duplicated file names unless some character is appended to some file names.
Using a period as prefix is a good option because when filenames get sorted the file names starting with a period will appear before the ones starting with zero, and therefore the first pages in roman numerals will get sorted correctly.
