Python Function

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

Parameter	Description
point_pair_info	Dict, dictionary 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 transformation matrix information 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.
