gen_region

Herror ::gen_region_histo ( Hobject *Region, const HTuple &Histogramm, const HTuple &Row, const HTuple &Column, const HTuple &Scale ) HRegion HRegion::GenRegionHisto ( const HTuple &Histogramm, const HTuple &Row, const HTuple &Column, const HTuple &Scale )

Convert a histogram into a region.

::gen_region_histo converts a histogram created with ::gray_histo into a region. The effect of the three control parameters is the same as in ::disp_image and ::set_paint.

Parameters

`Region` (output_object)	region `->` Hobject : HRegion*
Region containing the histogram.

`Histogramm` (input_control)	histogram-array `->` HTuple.long
Input histogram.

`Row` (input_control)	point.y `->` HTuple.long
Row coordinate of the center of the histogram.
Default value: 255
Suggested values: 100, 200, 255, 300, 400
Typical range of values: `0 <= Row <= 511`

`Column` (input_control)	point.x `->` HTuple.long
Column coordinate of the center of the histogram.
Default value: 255
Suggested values: 100, 200, 255, 300, 400
Typical range of values: `0 <= Column <= 511`

`Scale` (input_control)	integer `->` HTuple.long
Scale factor for the histogram.
Default value: 1
List of values: 1, 2, 3, 4, 5, 6, 7
Typical range of values: `1 <= Scale <= 10` (lin)
Minimum increment: 1
Recommended increment: 1

Result

::gen_region_histo returns H_MSG_TRUE if all parameters are correct. If necessary, an exception handling is raised.
