in the scanned image there are words between watermark , Watermark is start from bottom-left to top-right.
and text are written vertically. I want to remove watermark only not text also , I want to increase text strength , that weaken due to thresholding of image.
I tried it using get and set pixel , and also lockbits method, but unable to understand , if anybody have idea how to remove watermark and text strength , please let me know. C#
