Python Function

matrix, ret = acl.himpi.vpc_get_affine_transform(point_pair_info)

Parameter	Description
point_pair_info	Dict, dictionary that contains three pairs of pixel coordinates in the input and output images. Each pair contains pixel coordinates of an input image and an output image, respectively. For details, see hi_point_pair_info.

Return Value	Description
matrix	Dict, dictionary of the matrix required for affine transformation. Set matrix_type based on the actual input matrix. For details, see hi_transform_matrix.
ret	Int, error code. 0 indicates success. Other values indicate failure. For details, see VPC Return Codes.
