gen_region_points — Store individual pixels as image region.
The operator gen_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:
Created region.
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 (lin)
Minimum increment: 1
Recommended increment: 1
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 (lin)
Minimum increment: 1
Recommended increment: 1
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).
The operator gen_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'>). If an empty region is created (by the clipping or by an empty input) the operator set_system('store_empty_region',<'true'/'false'>) determines whether the region is returned or an empty object tuple.
