FxBitonalDilate4 

Dilates black pixels on a GdPicture image or into an area of a GdPicture image defined by SetROI() function.
This filter helps to dilate black pixels in the 2 directions: N, S, W, E. His action is less sensitive than FxDilate8.
It can be used used to improve very fine and degraded characters.
This function should be use only on bitonal images.  

 

FxBitonalDilate8

This filter helps to dilate black pixels in the 8 directions: E, NE, SE, S, SW, W, NW, N. His action is more sensitive than FxDilate4.
This function should be use only on bitonal images.  

 

FxBitonalDilateV 

Dilates black pixels on a GdPicture image or into an area of a GdPicture image defined by SetROI() function.
This filter helps to dilate black pixels in the 2 directions: N, S. His action is less sensitive than FxDilate4.
This function should be use only on bitonal images.  

 

FxBitonalErode4 

Erodes black pixels on a GdPicture image or into an area of a GdPicture image defined by SetROI() function.
