favSetRoi2D
AVVIEWER Subroutine: Sets the Region of Interest (ROI) within the
current 2D array "slice".
Module: USE AVVIEWER
Syntax
- favSetRoi2D (hv, col_start, row_start, num_cols, num_rows, status)
- hv
-
A handle that references an instance of Array Viewer created by
favStartViewer.
- col_start
-
An input argument of type INTEGER(4). It specifies the lower array index of the
current column dimension to be included in the ROI.
- row_start
-
An input argument of type INTEGER(4). It specifies the lower array index of the
current row dimension to be included in the ROI.
- num_cols
-
An input argument of type INTEGER(4). It specifies the number of columns to be
included in the ROI.
- num_rows
-
An input argument of type INTEGER(4). It specifies the number of rows to be
included in the ROI.
- status
-
An output argument of type INTEGER(4). It returns a status code for the success of
this call. The value 0 indicates success.
Remarks
This subroutine is similar to the favSetRoi subroutine,
which also updates the current ROI. However, favSetRoi2D is more convenient to use
in cases where the current 2D slice of the array is not being changed.
