disp_distribution

Herror ::disp_distribution ( const HTuple &WindowHandle, const HTuple &Distribution, const HTuple &Row, const HTuple &Column, const HTuple &Scale ) void HWindow::DispDistribution ( const HTuple &Distribution, const HTuple &Row, const HTuple &Column, const HTuple &Scale ) const

Displays a noise distribution.

::disp_distribution displays a distribution in the window. The parameters are the same as in ::set_paint(WindowHandle,'histogram') or ::gen_region_histo. Noise distributions can be generated with operations like ::gauss_distribution or ::noise_distribution_mean.

Parameters

`WindowHandle` (input_control)	window `->` HTuple.long
Window identifier.

`Distribution` (input_control)	real-array `->` HTuple.double
Gray value distribution (513 values).

`Row` (input_control)	point.y `->` HTuple.long
Row index of center.
Default value: 256
Suggested values: 0, 64, 128, 256
Typical range of values: `0 <= Row <= 511` (lin)
Minimum increment: 1
Recommended increment: 10

`Column` (input_control)	point.x `->` HTuple.long
Column index of center.
Default value: 256
Suggested values: 0, 64, 128, 256
Typical range of values: `0 <= Column <= 511` (lin)
Minimum increment: 1
Recommended increment: 10

`Scale` (input_control)	integer `->` HTuple.long
Size of display.
Default value: 1
Suggested values: 1, 2, 3, 4, 5, 6

Example

open_window(0,0,-1,-1,"root","visible","",&WindowHandle) ;
set_draw(WindowHandle,"fill") ;
set_color(WindowHandle,"white") ;

read_image(Image,"affe") ;
draw_region(&Region,WindowHandle) ;
noise_distribution_mean(Region,Image,21,&Distribution) ;
disp_distribution (WindowHandle,Distribution,100,100,3) ;

Possible Predecessors

::open_window, ::set_draw, ::set_color, ::set_colored, ::set_line_width, ::set_rgb, ::set_hsi, ::noise_distribution_mean, ::gauss_distribution
