MregDraw

Specifies the identifier of the graphics context to use when drawing. This parameter must be set to one of the following value. Note that while this parameter is required for calling MregDraw(), when using an M_EXTENDED_DEPTH_OF_FIELD_RESULT result buffer, this parameter will not affect the function.

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 identifier of the registration result buffer from which to extract the results to draw. The registration result buffer must have been previously allocated on the required system using MregAllocResult().

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.

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

For specifying the operation
Value	Description
M_DRAW_BOX	Draws the bounding box of the image associated with the specified registration element, at its position, angle, and scale. The position, angle, and scale are determined by the registration. Note that this operation is only available for an M_STITCHING_RESULT registration result buffer. (summarize) Draws the bounding box of the image associated with the specified registration element, at its position, angle, and scale. (more details...)
M_DRAW_EDOF_IMAGE	Draws the extended depth of field (EDoF) image into the target buffer. The DstImageBufOrListGraId input must be an image buffer. The Index parameter must be set to M_DEFAULT. Note that this operation is only available for an M_EXTENDED_DEPTH_OF_FIELD_RESULT registration result buffer. (summarize) Draws the extended depth of field (EDoF) image into the target buffer. (more details...)

Specifies the registration element that is associated with the image whose features you want to draw when drawing results of an M_STITCHING_RESULT registration result buffer. This parameter must be set to one of the values below.

For specifying the registration element
Value	Description
M_DEFAULT	Specifies the default value. For an M_STITCHING_RESULT result buffer, same as M_ALL. For an M_EXTENDED_DEPTH_OF_FIELD_RESULT result buffer, this is the only possible value. (summarize) Specifies the default value. (more details...)
M_ALL	Specifies all registration elements.
0 <= Value <= M_NUMBER_OF_ELEMENTS-1	Specifies the registration element's index.

Reserved for future expansion and must be set to M_DEFAULT.
