MmetDraw

Specifies the identifier of the graphics context to use when drawing. This parameter must be set to one of the following values:

For specifying the graphics context
Value	Description
M_DEFAULT	Specifies that the default graphics context of the current MIL application is used. Note that there is a different default graphics context for each thread. (summarize) Specifies that the default graphics context of the current MIL application is used. (more details...)
MIL graphics context identifier	Specifies a valid graphics context identifier, which you have allocated using MgraAlloc().

Specifies the metrology result buffer or context from which to extract the features to draw. The metrology result buffer must have been previously allocated using MmetAllocResult(). The metrology context must have been previously allocated using MmetAlloc().

If you are using MmetDraw() with a metrology context, you can specify that a feature or tolerance in the context should not be drawn, using MmetControl() with M_DRAWABLE set to M_DISABLE. This can be useful if you have many features or tolerances and you want to draw all of them in one call, although there are some that you do not want to see. When features or tolerances are not drawn, you cannot affect them in an interactive display.

Specifies the identifier of the destination image buffer or graphics list in which to draw. The buffer can be any valid MIL image buffer allocated using MbufAlloc...(). The graphics list must be previously allocated using MgraAllocList(). By drawing into a display's overlay buffer or associating the graphics list with the display, you can also annotate an image non-destructively.

If specifying an image buffer, it must not have a region of interest (ROI) associated with it. Using an image buffer with an ROI will cause an error.

When using MmetDraw() to draw features with a source model that is associated with a calibration context and if a calibration context is associated with the destination buffer, the latter must also be calibrated to the same world coordinate system. If no calibration context is associated with the destination buffer, the latter will use the same one as the template reference's. To add a template reference to a metrology context, use MmetControl() with M_TEMPLATE_REFERENCE_ID. MmetDraw() draws all the requested features according to whether the destination image buffer is physically corrected or not.

Specifies the type of drawing operation to perform. This parameter can be set to the following values:

For drawing a context characteristic
Value	Description
M_DRAW_TEMPLATE_REFERENCE	Draws the template reference. The LabelOrIndex parameter must be set to M_GENERAL. This operation cannot draw in a graphics list. (summarize) Draws the template reference. (more details...)

For the following constants, the LabelOrIndex parameter can be set to M_FEATURE_LABEL(), M_FEATURE_INDEX(), or M_ALL_FEATURES, unless otherwise specified.

For drawing a feature characteristic
Value	Description
M_DRAW_ACTIVE_EDGELS	Draws only the edgels that satisfied all edgel constraints.
M_DRAW_ALL_EDGELS	Draws all the edgels that were calculated in the target image. This includes the edgels that were used to measure a feature. (summarize) Draws all the edgels that were calculated in the target image. (more details...)
M_DRAW_FEATURE +	Draws the specified feature(s). In this case, you can also set the LabelOrIndex parameter to M_GLOBAL_FRAME. (summarize) Draws the specified feature(s). (more details...)
M_DRAW_FITTED_EDGELS	Draws only the edgels that satisfied all edgel constraints and fit constraints. The fitted edgels are those used by the fit operation to define a feature. (summarize) Draws only the edgels that satisfied all edgel constraints and fit constraints. (more details...)
M_DRAW_REGION	Draws the feature's search region. When drawing in a graphics list, this operation cannot draw ring and ring sector regions when M_REGION_ACCURACY_HIGH is set to M_DISABLE and the graphics context's input units is set to world units (MgraControl() with M_INPUT_UNITS set to M_WORLD). (summarize) Draws the feature's search region. (more details...)

For the following constants, the LabelOrIndex parameter can be set to M_TOLERANCE_LABEL(), M_TOLERANCE_INDEX(), M_ALL_TOLERANCES, M_ALL_PASS_TOLERANCES, M_ALL_FAIL_TOLERANCES, or M_ALL_WARNING_TOLERANCES.

For drawing a tolerance characteristic
Value	Description
M_DRAW_TOLERANCE +	Draws the geometric tolerance's symbol. Tolerance symbols are illustrated in MmetAddTolerance(). (summarize) Draws the geometric tolerance's symbol. (more details...)
M_DRAW_TOLERANCE_FEATURES	Draws the features used to define a tolerance. The LabelOrIndex parameter can be set to M_TOLERANCE_LABEL(), M_TOLERANCE_INDEX(), M_ALL_TOLERANCES, M_ALL_PASS_TOLERANCES, M_ALL_FAIL_TOLERANCES, or M_ALL_WARNING_TOLERANCES. (summarize) Draws the features used to define a tolerance. (more details...)

Combination constants for M_DRAW_FEATURE; M_DRAW_TOLERANCE.

You can add one of the following values to the above-mentioned values to specify that the label or name of the feature or tolerance will also be drawn .

For M_DRAW_FEATURE and M_DRAW_TOLERANCE
Combination value	Description
M_DRAW_LABEL	Specifies that the label will also be drawn.
M_DRAW_NAME	Specifies that the name will also be drawn.

Specifies the label or index of the result in the metrology result buffer for which to perform the drawing operation, or specifies that you are performing a general drawing operation for the metrology context. Set this parameter to one of the following values:

For specifying the index of the element in the metrology result buffer

M_DEFAULT	Specifies the default setting. M_DEFAULT is the same as M_ALL_FEATURES, when setting the Operation parameter to a value in the For drawing a feature characteristic table. M_DEFAULT is the same as M_ALL_TOLERANCES, when setting the Operation parameter to a value in the For drawing a tolerance characteristic table. M_DEFAULT is the same as M_GENERAL, when setting the Operation parameter to a value in the For drawing a context characteristic table. (summarize) Specifies the default setting. (more details...)
M_FEATURE_INDEX ( MIL_INT FeatureIndex )	Specifies the index value of an existing individual feature to draw, in either the metrology context or result buffer, depending on whether you provide a context or result buffer to the ContextOrResultMetId parameter.
