set_rgbT_set_rgbSetRgbSetRgb (Operator)

Name

set_rgbT_set_rgbSetRgbSetRgb — Set the color definition via RGB values.

Signature

set_rgb( : : WindowHandle, Red, Green, Blue : )

Herror T_set_rgb(const Htuple WindowHandle, const Htuple Red, const Htuple Green, const Htuple Blue)

void SetRgb(const HTuple& WindowHandle, const HTuple& Red, const HTuple& Green, const HTuple& Blue)

void HWindow::SetRgb(Hlong Red, Hlong Green, Hlong Blue) const

void HWindow.SetRgb(HTuple red, HTuple green, HTuple blue)

void HWindow.SetRgb(int red, int green, int blue)

Description

set_rgbset_rgbSetRgbSetRgbSetRgb sets the output color(s) or the gray values, respectively, for region output for the window. The colors are defined with the red, green and blue components. If only one combination is passed, all output takes place in that color. If a tuple is passed, region output and output of geometric objects takes place modulo the passed colors.

For every call of an output operator, output is started with the first color. If only one object is displayed per call, it will always be displayed in the first color. This is even true for objects with multiple connection components. If multiple objects are displayed per operator call, multiple colors are used. The defined colors are used until set_colorset_colorSetColorSetColorSetColor, set_rgbset_rgbSetRgbSetRgbSetRgb or set_grayset_graySetGraySetGraySetGray is called again. The values are used by operators like disp_regiondisp_regionDispRegionDispRegionDispRegion, disp_linedisp_lineDispLineDispLineDispLine, disp_rectangle1disp_rectangle1DispRectangle1DispRectangle1DispRectangle1, disp_rectangle2disp_rectangle2DispRectangle2DispRectangle2DispRectangle2, disp_arrowdisp_arrowDispArrowDispArrowDispArrow, etc.

Attention

If a passed is not available, an exception is raised. If set_check(::'~color':) was called before, HALCON uses a similar color and suppresses the error.

Parameters

Window handle.

RedRedRedRedred (input_control)  integer(-array) HTupleHTupleHtuple (integer) (int / long) (Hlong) (Hlong)

Red component of the color.

Default value: 255

Typical range of values: 0 ≤ Red Red Red Red red ≤ 255

Restriction: 0 <= Red && Red <= 255

GreenGreenGreenGreengreen (input_control)  integer(-array) HTupleHTupleHtuple (integer) (int / long) (Hlong) (Hlong)

Green component of the color.

Default value: 0

Typical range of values: 0 ≤ Green Green Green Green green ≤ 255

Restriction: 0 <= Green && Green <= 255

BlueBlueBlueBlueblue (input_control)  integer(-array) HTupleHTupleHtuple (integer) (int / long) (Hlong) (Hlong)

Result

set_rgbset_rgbSetRgbSetRgbSetRgb returns 2 (H_MSG_TRUE) if the window is valid and all passed colors are available and displayable. Otherwise an exception is raised.
