dev_set_drawdev_set_drawDevSetDrawDevSetDrawdev_set_draw — Define the region fill mode.

Signature

dev_set_draw( : : DrawMode : )

Herror dev_set_draw(const char* DrawMode)

Herror T_dev_set_draw(const Htuple DrawMode)

void DevSetDraw(const HTuple& DrawMode)

static void HWindow::DevSetDraw(const HString& DrawMode)

static void HWindow::DevSetDraw(const char* DrawMode)

static void HWindow::DevSetDraw(const wchar_t* DrawMode)   ( Windows only)

static void HOperatorSet.DevSetDraw(HTuple drawMode)

static void HWindow.DevSetDraw(string drawMode)

def dev_set_draw(draw_mode: str) -> None

Description

dev_set_drawdev_set_drawDevSetDrawDevSetDrawdev_set_draw defines the fill mode for regions. If DrawModeDrawModeDrawModedrawModedraw_mode is set to 'fill'"fill""fill""fill""fill", regions are displayed filled, if set to 'margin'"margin""margin""margin""margin", only contours are displayed. In the 'margin'"margin""margin""margin""margin" mode, the appearance of the contours can be affected by dev_set_line_widthdev_set_line_widthDevSetLineWidthDevSetLineWidthdev_set_line_width and set_line_styleset_line_styleSetLineStyleSetLineStyleset_line_style.

For more information see the description of the operator set_drawset_drawSetDrawSetDrawset_draw. However, in contrast to that operator the draw mode 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

DrawModeDrawModeDrawModedrawModedraw_mode (input_control)  string → HTuplestrHTupleHtuple (string) (string) (HString) (char*)

Fill mode for region output.

Default: 'fill' "fill" "fill" "fill" "fill"

List of values: 'fill'"fill""fill""fill""fill", 'margin'"margin""margin""margin""margin"

Example (HDevelop)

read_image(Image,'monkey')
threshold(Image,Region,128,255)
dev_clear_window ()
dev_set_color('red')
dev_set_draw('fill')
dev_display(Region)
dev_set_color('white')
dev_set_draw('margin')
dev_display(Region)

Result

If the values of the specified parameters are correct, dev_set_drawdev_set_drawDevSetDrawDevSetDrawdev_set_draw returns 2 ( H_MSG_TRUE) . Otherwise, an exception is raised and an error code returned.

Possible Successors

dev_set_line_widthdev_set_line_widthDevSetLineWidthDevSetLineWidthdev_set_line_width, dev_displaydev_displayDevDisplayDevDisplaydev_display
