Synopsis
Perform a point-to-point bit shift.
Syntax
void MimShift(
MIL_ID SrcImageBufId, //in
MIL_ID DstImageBufId, //in
MIL_INT NbBitsToShift //in
)
Description

This function performs left or right bit-shifting on each pixel in the specified image. The shift operation is signed or unsigned depending on the source image buffer's data type.

Note that floating-point values will be cast to MIL_UINT32 before performing the shift operation (except when shifting by 0). Therefore, unexpected results can occur if a floating-point value is larger than the MIL_UINT32 range.

Note that, if you shift by 0, only a copy operation will be performed.

You can limit this function's results to a region of an image buffer using a region of interest (ROI) set using MbufSetRegion(). The ROI must be defined in raster format (M_RASTER or M_VECTOR_AND_RASTER). An error is generated if the ROI is only in vector format (M_VECTOR).

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
SrcImageBufId

Specifies the identifier of the data source of the operation. This parameter must be given an image buffer identifier.

If you specify an image buffer that has an ROI associated with it, the ROI must be in raster format; otherwise, you will get an error.

DstImageBufId

Specifies the identifier of the destination of the results. This parameter must be given an image buffer identifier.

If you specify an image buffer that has an ROI associated with it, the ROI must be in raster format; otherwise, you will get an error.

NbBitsToShift

Specifies the number of bits to shift. If the given value is negative, each pixel in the specified image is right bit-shifted by the specified number of bits; otherwise, it is left bit-shifted.
