Description

The operator smallest_rectangle1_xldsmallest_rectangle1_xldSmallestRectangle1XldSmallestRectangle1XldSmallestRectangle1Xldsmallest_rectangle1_xld calculates the enclosing rectangle (parallel to the coordinate axes) for each input contour or polygon. The enclosing rectangle is described by the coordinates of the corner pixels (Row1Row1Row1Row1row1row_1,Column1Column1Column1Column1column1column_1,Row2Row2Row2Row2row2row_2,Column2Column2Column2Column2column2column_2)

If more than one contour or polygon is passed, the results are stored in tuples in the same order as the respective contours or polygons in XLDXLDXLDXLDXLDxld. In case of an empty contour all parameters have the value 0 if no other behavior was set (see set_systemset_systemSetSystemSetSystemSetSystemset_system).

Attention

In case of empty contours the result of Row1Row1Row1Row1row1row_1,Column1Column1Column1Column1column1column_1, Row2Row2Row2Row2row2row_2 and Column2Column2Column2Column2column2column_2 (all are 0) can lead to confusion.

Parameters

Contours or polygons to be examined.

Row1Row1Row1Row1row1row_1 (output_control)  rectangle.origin.y(-array) HTupleSequence[float]HTupleHtuple (real) (double) (double) (double)

Row coordinate of upper left corner point of the enclosing rectangle.

Column coordinate of upper left corner point of the enclosing rectangle.

Row2Row2Row2Row2row2row_2 (output_control)  rectangle.corner.y(-array) HTupleSequence[float]HTupleHtuple (real) (double) (double) (double)

Row coordinate of lower right corner point of the enclosing rectangle.

Column coordinate of lower right corner point of the enclosing rectangle.

Complexity

If N is the number of contour points, the runtime complexity is O(N).

Result

smallest_rectangle1_xldsmallest_rectangle1_xldSmallestRectangle1XldSmallestRectangle1XldSmallestRectangle1Xldsmallest_rectangle1_xld returns 2 (H_MSG_TRUE) if the input is not empty. If the input is empty the behavior can be set via set_system(::'no_object_result',<Result>:)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)set_system("no_object_result",<Result>). If necessary, an exception is raised.
