dev_set_line_width🔗
Short description🔗
dev_set_line_width — Define the line width for region contour output.
Signature🔗
dev_set_line_width( integer LineWidth )
Description🔗
dev_set_line_width defines the line width (in pixel) that is used to
display region contours (in 'margin' mode), XLDs, and other
geometric output (e.g., disp_region, disp_line, etc.).
For more information see the description of the operator
set_line_width.
However, in contrast to that operator the new line width is also used for
all new graphics windows that are opened afterwards.
Attention🔗
Using the code export feature of HDevelop, the code that is generated
for this operator may have a different behavior than the related
HALCON operator.
For a detailed description of the code export of HDevelop graphics
operators into the different programming languages see in the
“HDevelop User's Guide” the chapter Code Export
-> General Aspects of Code Generation
-> Graphics Windows.
Parameters🔗
LineWidth (input_control) integer → (integer)
Line width for region output in contour mode.
Default: 1
Restriction: LineWidth >= 1
Example🔗
(HDevelop)
read_image(Image,'monkey')
threshold(Image,Region,128,255)
dev_set_draw('margin')
dev_set_line_width(5)
dev_clear_window ()
dev_display(Region)
Result🔗
If the values of the specified parameters are correct,
dev_set_line_width returns 2 (H_MSG_TRUE). Otherwise, an
exception is raised and an error code returned.
