With LEADTOOLS it is easy to handle the segmentation process, whether performing segmentation automatically or manually. A segment is a rectangular area on the bitmap. A segment's type depends on the content of its area. The segmentation process classifies the segments of a bitmap as background, text, grayscale or picture. The segmentation process breaks the image into different 9 types:
Background (The most prevalent color in the document)
One color Segment
1 bit black and white (Text) Segment
1 bit color Segment
2 bit color Segment
2 bit grayscale Segment
2 bit black and white (Text) Segment.
8-bit grayscale Segment
Call the L_MrcStartBitmapSegmentation function to initialize the segmentation process, before calling any of the segmentation methods. When the handle to the segmentation is no longer needed, free it by calling the L_MrcStopBitmapSegmentation function.
Each call to the L_MrcStartBitmapSegmentation function requires a corresponding call to the L_MrcStopBitmapSegmentation function.
