Detailed Description

HxValue L_HXIMAGEREP HxIdentMaskSum ( HxImageRep im,

HxImageRep mask,

HxPoint p,

HxSizes size,

int label

)

Compute the sum of all pixels in "im" identified by "mask".
"mask" is assumed to be an identification image with pixel type short. The function considers all pixels within the area starting at point "p" with given "size" and a value equal to label.
Implementation specifics :

Pattern : Export operation with an extra image
Variation : Translation invariant, 1 phase export operation with an extra image
The pixel functor : HxExportExtraIdentMaskSum
Instantiations : HxInstExportExtraIdentMaskSum_c
