smallest_rectangle1_xldsmallest_rectangle1_xldSmallestRectangle1XldSmallestRectangle1Xld — Enclosing rectangle parallel to the coordinate axes of contours or polygons.

static void HOperatorSet.SmallestRectangle1Xld(HObject XLD, out HTuple row1, out HTuple column1, out HTuple row2, out HTuple column2)
void HXLD.SmallestRectangle1Xld(out HTuple row1, out HTuple column1, out HTuple row2, out HTuple column2)
void HXLD.SmallestRectangle1Xld(out double row1, out double column1, out double row2, out double column2)
The operator smallest_rectangle1_xldsmallest_rectangle1_xldSmallestRectangle1XldSmallestRectangle1XldSmallestRectangle1Xld 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 (Row1Row1Row1Row1row1,Column1Column1Column1Column1column1,Row2Row2Row2Row2row2,Column2Column2Column2Column2column2)
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
XLDXLDXLDXLDXLD. In case of an empty contour all parameters have the value 0
if no other behavior was set (see set_systemset_systemSetSystemSetSystemSetSystem).
In case of empty contours the result of Row1Row1Row1Row1row1,Column1Column1Column1Column1column1,
Row2Row2Row2Row2row2 and Column2Column2Column2Column2column2 (all are 0) can lead to confusion.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Automatically parallelized on tuple level.
Contours or polygons to be examined.
Row coordinate of upper left corner point of the
enclosing rectangle.
Column coordinate of upper left corner point of the
enclosing rectangle.
Row coordinate of lower right corner point of the
enclosing rectangle.
Column coordinate of lower right corner point of the
enclosing rectangle.
If N is the number of contour points, the runtime complexity is
O(N).
smallest_rectangle1_xldsmallest_rectangle1_xldSmallestRectangle1XldSmallestRectangle1XldSmallestRectangle1Xld 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>). If
necessary, an exception is raised.
