We have a plugin which reads the scanned document text. The plugin works as OCR (Optical Character Recognition).The page is drawn into the whole-image compatible device context and saved the page(Clipped Image) as BMP. Using some functions its reading the text from BMP. Its working good for some documents. Inorder to increase the performance on some other scanned documents,what we have to do? We are using
1)GDI B&W Palette object handler
2)B&W Logical palette structure
3)compitable memory device context for the whole image
4)pointer to Bitmap Info structure for the whole image
5)pointer to bits of the whole image
the above mentioned points are applied for whole and clipped Image.
