gen_region_histoT_gen_region_histoGenRegionHistoGenRegionHistogen_region_histo (Operator)

Name

gen_region_histoT_gen_region_histoGenRegionHistoGenRegionHistogen_region_histo — Convert a histogram into a region.

Signature

gen_region_histo( : Region : Histogram, Row, Column, Scale : )

Description

gen_region_histogen_region_histoGenRegionHistoGenRegionHistoGenRegionHistogen_region_histo converts a histogram created with gray_histogray_histoGrayHistoGrayHistoGrayHistogray_histo, gray_histo_rangegray_histo_rangeGrayHistoRangeGrayHistoRangeGrayHistoRangegray_histo_range ,or tuple_histo_rangetuple_histo_rangeTupleHistoRangeTupleHistoRangeTupleHistoRangetuple_histo_range into a region. RowRowRowRowrowrow and ColumnColumnColumnColumncolumncolumn define the position of the center of the graphic. ScaleScaleScaleScalescalescale allows scaling of the graphic, whereby 1 means displaying all 256 values, 2 means displaying 128 values, 3 means displaying only 64 values, etc.

Execution Information
