For example, this value is equivalent to 0xFF for an 8-bit buffer. Note that a grayscale value can be any integer or floating-point number. If the given value exceeds the range of the possible values that can be stored in each band of the destination buffer, the least significant bits of the value are used. (summarize) Specifies a grayscale value. (more details...)
M_DRAW_OFFSET_X		Sets the offset to subtract from the source X-coordinates before rendering the graphic. This is useful to take results obtained relative to an offset and draw them relative to the top-left corner of the destination image of a draw operation. INQ (summarize) Sets the offset to subtract from the source X-coordinates before rendering the graphic. INQ (more details...)
	M_DEFAULT	Specifies the default value; the default value is 0.0 pixels.
	Value	Specifies the X-coordinate offset to subtract, in pixels.
M_DRAW_OFFSET_Y		Sets the offset to subtract from the source Y-coordinates before rendering the graphic. This is useful to take results obtained relative to an offset and draw them relative to the top-left corner of the destination image of a draw operation. INQ (summarize) Sets the offset to subtract from the source Y-coordinates before rendering the graphic. INQ (more details...)
	M_DEFAULT	Specifies the default value; the default value is 0.0 pixels.
	Value	Specifies the Y-coordinate offset to subtract, in pixels.
M_DRAW_ZOOM_X		Sets the scale factor in the X-direction. This value is useful to zoom drawings of results. INQ (summarize) Sets the scale factor in the X-direction. INQ (more details...)
	M_DEFAULT	Specifies the default value; the default value is 1.0.
	Value > 0	Specifies the scale factor in the X-direction.

	M_DEFAULT	Specifies the default value; the default value is 1.0.
	Value > 0	Specifies the scale factor in the Y-direction.
M_FIXTURE		Sets the calibration information to use when rendering (drawing or displaying) a graphic that has been defined in world units (M_INPUT_UNITS set to M_WORLD). MIL can interpret positioning and dimensioning information of the graphic solely using the calibration information associated with the destination image buffer (or the image buffer selected to the display). Alternatively, you can have MIL use the explicitly specified calibration information (M_GRAPHIC_SOURCE_CALIBRATION). If only the destination or the graphic is associated with calibration information, it will be used to render the graphic. However, if both are available, you should use M_FIXTURE to identify with respect to which of their relative coordinate systems has positioning and dimensioning information been specified. If with respect to that of the destination calibration information (M_USE_DESTINATION_FIRST), the source calibration information is not used. If with respect to that of the source calibration information (M_USE_SOURCE_FIRST), positions and dimensions are transformed from this relative coordinate system to the absolute coordinate system; then, since it is assumed that there is only one absolute coordinate system, these positions and dimensions are transformed from the absolute coordinate system to the pixel coordinate system, using the destination calibration information. INQ (summarize) Sets the calibration information to use when rendering (drawing or displaying) a graphic that has been defined in world units (M_INPUT_UNITS set to M_WORLD). INQ (more details...)
	M_USE_DESTINATION_FIRST	Specifies that the calibration information of the destination is used when rendering the graphic. In this case, the graphic follows the relative coordinate system of the destination. This is most often used when working with ROIs. This is the default value. (summarize) Specifies that the calibration information of the destination is used when rendering the graphic. (more details...)
	M_USE_SOURCE_FIRST	Specifies that the calibration information of the graphic, set with M_GRAPHIC_SOURCE_CALIBRATION, is used when rendering the graphic. In this case, the graphic is positioned independent of the destination's relative coordinate system; the destination calibration information is only used, if available, for the world to pixel mapping. (summarize) Specifies that the calibration information of the graphic, set with M_GRAPHIC_SOURCE_CALIBRATION, is used when rendering the graphic. (more details...)
M_GRAPHIC_CONVERSION_MODE		Sets how the shape of a graphic, defined in world units, is converted to pixels (rendered). Drawings created using a processing or analysis module draw function (M...Draw()) ignore this control type; instead the graphics are drawn using settings defined in their respective modules. INQ (summarize) Sets how the shape of a graphic, defined in world units, is converted to pixels (rendered). INQ (more details...)
	M_PRESERVE_SHAPE_AVERAGE	Specifies to render the graphic so that its shape is preserved, even if it means not respecting the calibration information exactly. For example, a rectangle in world units will be mapped to a rectangle in pixel units, even if the accurate conversion would not yield a rectangle. This setting applies only to dots (MgraDot() and MgraDots()) and to rectangles (MgraRect() and MgraRectAngle()). (summarize) Specifies to render the graphic so that its shape is preserved, even if it means not respecting the calibration information exactly. (more details...)
	M_RESHAPE_FOLLOWING_DISTORTION	Specifies that all points along the contour of the graphic will be converted using the calibration information, following any non-linear distortion. This mode is slower, but more accurate. (summarize) Specifies that all points along the contour of the graphic will be converted using the calibration information, following any non-linear distortion. (more details...)
	M_RESHAPE_FROM_POINTS	Specifies that only a few key points or features will be converted using the calibration information; from these converted points, the rest of the graphic will be rendered respecting the shape of the graphic. For example, when converting a line segment from world to pixel units, the two end points are mapped to pixel units, and then a straight line is drawn connecting these two points, ignoring any non-linear distortion in-between. This is the fastest mode, and is accurate as long as there is only linear distortion. This is the default value. (summarize) Specifies that only a few key points or features will be converted using the calibration information; from these converted points, the rest of the graphic will be rendered respecting the shape of the graphic. (more details...)
M_GRAPHIC_SOURCE_CALIBRATION		Sets the calibration information to use to interpret positioning and dimensioning information of a graphic defined in world units (M_INPUT_UNITS set to M_WORLD), if you have set M_FIXTURE to M_USE_SOURCE_FIRST. If the destination also has calibration information, positioning and dimensioning information are transformed from the relative coordinate system of the source calibration information to its absolute coordinate system. Then, since it is assumed that there is only one absolute coordinate system, the dimensions and positions are transformed from the absolute coordinate system to the pixel coordinate system, using the destination calibration information. Note that this calibration information is also used if you have set M_FIXTURE to M_USE_DESTINATION_FIRST, but the graphic is drawn in an image buffer that has no calibration information. INQ (summarize) Sets the calibration information to use to interpret positioning and dimensioning information of a graphic defined in world units (M_INPUT_UNITS set to M_WORLD), if you have set M_FIXTURE to M_USE_SOURCE_FIRST. INQ (more details...)
	M_NULL	Specifies that no source calibration information is available to interpret positioning and dimensioning information of a graphic defined in world units, except when the graphic is drawn using the draw function (M...Draw()) of a processing or analysis module; in this case, the calibration information of the drawn setting or result will be used. This is the default value. (summarize) Specifies that no source calibration information is available to interpret positioning and dimensioning information of a graphic defined in world units, except when the graphic is drawn using the draw function (M...Draw()) of a processing or analysis module; in this case, the calibration information of the drawn setting or result will be used. (more details...)
	MIL Identifier	Specifies the identifier of a calibration context, image buffer or processing or analysis module result buffer, whose calibration information to use; this object is only associated with the graphics context, not copied. If, for example, the relative coordinate system changes after using M_GRAPHIC_SOURCE_CALIBRATION, it will be reflected in the calibration information that is used. (summarize) Specifies the identifier of a calibration context, image buffer or processing or analysis module result buffer, whose calibration information to use; this object is only associated with the graphics context, not copied. (more details...)
M_INPUT_UNITS		Sets the units with which to interpret the graphic's position and dimensional information. This essentially sets the input coordinate system to use. INQ (summarize) Sets the units with which to interpret the graphic's position and dimensional information. INQ (more details...)
	M_DISPLAY	Specifies to interpret the values in pixel units that, unlike M_PIXEL, are not altered when the display is panned or zoomed. This can be useful if, for example, you always want to display the camera's current frame rate at the top-left corner. M_DISPLAY must only be specified when drawing in a graphics list and the graphics list is used to annotate the display non-destructively, using MdispControl() with M_ASSOCIATED_GRAPHIC_LIST_ID. (summarize) Specifies to interpret the values in pixel units that, unlike M_PIXEL, are not altered when the display is panned or zoomed. (more details...)
	M_PIXEL	Specifies to interpret the values in pixel units, with respect to the pixel coordinate system. If you are drawing in a graphics list and the graphics list is used to annotate the display non-destructively (M_ASSOCIATED_GRAPHIC_LIST_ID), the graphic will be zoomed and panned according to the display's zoom and pan settings. This is not the case when setting the units to M_DISPLAY, which also uses pixel units. This is the default value. (summarize) Specifies to interpret the values in pixel units, with respect to the pixel coordinate system. (more details...)
	M_WORLD	Specifies to interpret the values in world units, with respect to the relative coordinate system. If you are drawing in a graphics list and the graphics list is used to annotate the display non-destructively (M_ASSOCIATED_GRAPHIC_LIST_ID), the graphic will be zoomed and panned according to the display's zoom and pan settings. When using M_WORLD, a graphic's coordinates are interpreted as real-world values and transformed to pixel values before being drawn or associated with the display non-destructively. Note that using the calibration information associated with the image (M_WORLD), ensures that whenever the relative coordinate system moves (for example, with McalRelativeOrigin(), McalSetCoordinateSystem(), or McalFixture()), the non-destructive annotations move accordingly. In this case, the position of the graphics is set according to the position of the relative coordinate system. If world units are specified, drawing a graphic or calling MgraFill() generates an error if the operation is performed on an uncalibrated image and M_GRAPHIC_SOURCE_CALIBRATION is set to M_NULL. (summarize) Specifies to interpret the values in world units, with respect to the relative coordinate system. (more details...)

The following ControlType and corresponding ControlValue parameter settings are used to change the graphics context settings that affect the interactivity of a graphic, drawn in a graphics list associated with a display, when interactive mode is enabled (MdispControl() with M_GRAPHIC_LIST_INTERACTIVE set to M_ENABLE).

Note, you can still change these settings even if interactive mode is disabled, but they will have no effect until interactive mode is enabled. Adding a graphic that does not support one of the following settings to a graphics list will automatically assign the setting of the graphic to M_DISABLE.
