disp_crossT_disp_crossDispCrossDispCross (Operator)

Name

disp_crossT_disp_crossDispCrossDispCross — Displays crosses in a window.

Signature

disp_cross( : : WindowHandle, Row, Column, Size, Angle : )

Herror T_disp_cross(const Htuple WindowHandle, const Htuple Row, const Htuple Column, const Htuple Size, const Htuple Angle)

void DispCross(const HTuple& WindowHandle, const HTuple& Row, const HTuple& Column, const HTuple& Size, const HTuple& Angle)

void HWindow::DispCross(const HTuple& Row, const HTuple& Column, double Size, double Angle) const

void HWindow::DispCross(double Row, double Column, double Size, double Angle) const

static void HOperatorSet.DispCross(HTuple windowHandle, HTuple row, HTuple column, HTuple size, HTuple angle)

void HWindow.DispCross(HTuple row, HTuple column, double size, double angle)

void HWindow.DispCross(double row, double column, double size, double angle)

Description

disp_crossdisp_crossDispCrossDispCrossDispCross displays one or several crosses in the output window. A cross is described by the coordinates of the center point (RowRowRowRowrow,ColumnColumnColumnColumncolumn), the length of its bars SizeSizeSizeSizesize and the orientation AngleAngleAngleAngleangle. The operators used to control the display of regions (e.g. set_colorset_colorSetColorSetColorSetColor, set_grayset_graySetGraySetGraySetGray, set_drawset_drawSetDrawSetDrawSetDraw, set_line_widthset_line_widthSetLineWidthSetLineWidthSetLineWidth) can also be used with crosses. Several crosses can be displayed with one call by using tuple parameters. For the use of colors with several crosses, see set_colorset_colorSetColorSetColorSetColor.
