#DUAL STREAMING IS REQUIRED FOR HTML VIEWING HOW TO#
Here is an example that demonstrates how to acquire both sides of page as black-white and color images with different resolutions: /Camera_Bitonal_Both - camera acquires the top and bottom sides of page as black-white images./Camera_Bitonal_Bottom - camera acquires only the bottom side of page as black-white image./Camera_Bitonal_Top - camera acquires only the top side of page as black-white image./Camera_Color_Both - camera acquires the top and bottom side of page as color images./Camera_Color_Bottom - camera acquires only the bottom side of page as color image./Camera_Color_Top - camera acquires only the top side of page as color image.Each camera has predefined settings (pixel type and page side) and customizable settings (resolution, brightness, contrast, threshold, filters, etc).įor example, most of Kodak scanners has 6 cameras:
SDK allows to use the Dual Stream feature of Kodak scanners.ĭual Stream feature means that scanner has some "cameras" and can make some snapshots of each acquired page.
