Name
draw_regiondraw_regionDrawRegiondraw_regionDrawRegionDrawRegion — Interactive drawing of a closed region.
draw_regiondraw_regionDrawRegiondraw_regionDrawRegionDrawRegion produces an image. The region of that image spans
exactly the image region entered interactively by mouse clicks (gray values
remain undefined).
Painting happens in the output window while keeping the left mouse button
pressed. The left mouse button even operates by clicking in the output window;
through this a line between the previous clicked points is drawn.
Clicking the right mouse button terminates input and closes the outline.
Subsequently the image is “filled up”. Also it contains the whole image area
enclosed by the mouse.
Painting uses that color which has been set by set_colorset_colorSetColorset_colorSetColorSetColor,
set_rgbset_rgbSetRgbset_rgbSetRgbSetRgb, etc. .
Pressing the right mouse button terminates the procedure. On OS X
draw_regiondraw_regionDrawRegiondraw_regionDrawRegionDrawRegion can also be terminated by pressing the escape key.
The output object's gray values are not defined.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
Interactive created region.
