Description

The operator gen_region_pointsgen_region_pointsGenRegionPointsGenRegionPointsGenRegionPointsgen_region_points creates a region described by a number of pixels. The pixels do not have to be stored in a fixed order, but the best runtime behavior is obtained when the pixels are stored in ascending order. The order is as follows:

The indicated coordinates stand for two consecutive pixels in the tuple.

Execution Information

Parameters

RegionRegionRegionRegionregionregion (output_object)  region → objectHRegionHObjectHRegionHobject *

Created region.

RowsRowsRowsRowsrowsrows (input_control)  coordinates.y(-array) → HTupleMaybeSequence[Union[int, float]]HTupleHtuple (integer / real) (int / long / double) (Hlong / double) (Hlong / double)

Lines of the pixels in the region.

Default value: 100

Suggested values: 0, 10, 30, 50, 100, 200, 300, 500

Typical range of values: Rows Rows Rows Rows rows rows (lin)

Minimum increment: 1

Recommended increment: 1

ColumnsColumnsColumnsColumnscolumnscolumns (input_control)  coordinates.x(-array) → HTupleMaybeSequence[Union[int, float]]HTupleHtuple (integer / real) (int / long / double) (Hlong / double) (Hlong / double)

Columns of the pixels in the region.

Number of elements: Columns == Rows

Default value: 100

Suggested values: 0, 10, 30, 50, 100, 200, 300, 500

Typical range of values: Columns Columns Columns Columns columns columns (lin)

Minimum increment: 1

Recommended increment: 1

Complexity

F shall be the number of pixels. If the pixels are sorted in ascending order the runtime complexity is: O(F), otherwise O(log(F)*F).

Result

The operator gen_region_pointsgen_region_pointsGenRegionPointsGenRegionPointsGenRegionPointsgen_region_points returns the value 2 (H_MSG_TRUE) if the pixels are located within the image format. Otherwise an exception is raised. The clipping according to the current image format is set via the operator set_system('clip_region',<'true'/'false'>)set_system("clip_region",<"true"/"false">)SetSystem("clip_region",<"true"/"false">)SetSystem("clip_region",<"true"/"false">)SetSystem("clip_region",<"true"/"false">)set_system("clip_region",<"true"/"false">). If an empty region is created (by the clipping or by an empty input) the operator set_system('store_empty_region',<'true'/'false'>)set_system("store_empty_region",<"true"/"false">)SetSystem("store_empty_region",<"true"/"false">)SetSystem("store_empty_region",<"true"/"false">)SetSystem("store_empty_region",<"true"/"false">)set_system("store_empty_region",<"true"/"false">) determines whether the region is returned or an empty object tuple.
