pixMorphDwa_3()

Input: pixd (usual 3 choices: null, == pixs, != pixs) pixs (1 bpp) operation (L_MORPH_DILATE, L_MORPH_ERODE, L_MORPH_OPEN, L_MORPH_CLOSE) sel name Return: pixd

Notes: (1) This simply adds a border, calls the appropriate pixFMorphopGen_*(), and removes the border. See the notes for that function. (2) The size of the border depends on the operation and the boundary conditions.

pixFMorphopGen_3()

Input: pixd (usual 3 choices: null, == pixs, != pixs) pixs (1 bpp) operation (L_MORPH_DILATE, L_MORPH_ERODE, L_MORPH_OPEN, L_MORPH_CLOSE) sel name Return: pixd

Notes: (1) This is a dwa operation, and the Sels must be limited in size to not more than 31 pixels about the origin. (2) A border of appropriate size (32 pixels, or 64 pixels for safe closing with asymmetric b.c.) must be added before this function is called. (3) This handles all required setting of the border pixels before erosion and dilation. (4) The closing operation is safe; no pixels can be removed near the boundary.
