Method SetupNormalization

deps/tesseract/ccstruct/normalis.cpp:95–114

Initializes the denorm for a transformation. For details see the large comment in normalis.h. Arguments: block: if not NULL, then this is the first transformation, and block->re_rotation() needs to be used after the Denorm transformation to get back to the image coords. rotation: if not NULL, apply this rotation after translation to the origin and scaling. (Usually a classify rotation.) predecesso

// final_xshift: The x component of the final translation.
// final_yshift: The y component of the final translation.
