Synopsis

Draw a labeled image.

Syntax

void MblobLabel(

MIL_ID ResultBlobId,	//in
MIL_ID DstImageBufId,	//in
MIL_INT64 ControlFlag	//in

)

Description

This function draws a labeled image in which each blob existing in the specified result buffer is represented with its own unique label value.

The label values are taken from the blob analysis result buffer. A call to MblobCalculate() must have been made to generate label values for an image. Blobs that have been deleted from the result buffer are not drawn.

Note that this function reference has not been updated for a MIL system added during a MIL update. Refer to the MIL system's release note to see which MIL system’s documentation you should use in its place and any possible differences.

Parameters

This function is not supported on the selected boards.

This function reference has not been updated for the selected MIL system. To show the content of this page, choose a second MIL system; refer to the MIL system's release note to see which MIL system’s documentation to choose and any possible differences.

Parameters

ResultBlobId

Specifies the identifier of the blob analysis result buffer.

DstImageBufId

Specifies the identifier of the destination (labeled) image buffer. This must be a single band, 8 or 16-bit unsigned buffer.

Note, this buffer need not be the same size as the original identifier image used to calculate the blobs, but must be 16 bits deep if the maximum label value exceeds 255. To determine if a 16-bit buffer is necessary, perform an M_MAX_LABEL_VALUE inquiry, using MblobGetResult(). The number of blobs alone does not tell you the maximum label value (label values are not necessarily contiguous).

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

ControlFlag

Specifies whether or not to clear the destination image buffer before drawing the labeled image into it. This parameter can be set to one of the following:

For the destination image buffer
Value	Description
M_CLEAR	Clears the destination image buffer before placing the labeled image into it.
M_NO_CLEAR	Does not clear the destination image buffer before placing the labeled image into it (background pixels will be unchanged).

Remark

The prototypes of functions in the Mblob module changed as of MIL 10 PP2. For C applications, by default the original prototypes are used to ensure backward-compatibility. To use the updated prototypes, add #define M_USE_OLD_MBLOB_API_IN_C 0 before including mil.h. For information about the original API for the Mblob module refer to the MIL 10 PP1 documentation, available online to registered users at https://www.matrox.com/imaging/en/products/software/mil/documentation/.
