Description

Set the X coordinate associated with the left most column of the matrix.

Syntax

BOOL SetXMin( double dXMin )

Parameters

dXMin: [input] Input X coordinate of left most column

Return

Returns TRUE on success and FALSE on failure.

Examples

EX1

// Set and get the X coordinate of the first column of a matrix
void Matrix_SetXMin_ex1()
{
// This sample code will print a message like below:
// Target matrix is Matrix1.
// Setting X min value succeeded.
// Obtained X min value is -1.23457e+008
// Check X min value by Matrix:Set Dimensions menu command if it is -1.234570e+008.
//
    BOOL rc;
    
    double dXMin;
    matrix<double> mat1 = {
        {1,  2},
        {3,  4},
        {5,  6}
    };

    MatrixPage MatPg1;
    MatPg1.Create("Origin");
    MatrixLayer MatLy1 = MatPg1.Layers(0);
    Matrix Mat1(MatLy1);
    Mat1 = mat1;
    printf("  Target matrix is %s.\n",Mat1.GetName());

    rc=Mat1.SetXMin(-123.4567E6);  // Use SetXMin to set the X coordinate of last column
    if(!rc) {
        printf("  Error: SetXMin failed.\n");
        return;
    }
    else printf("  Setting X min value succeeded.\n");
    dXMin = Mat1.GetXMin();   // Use GetYMin to get the X coordinate of last column
    printf("  Obtained X min value is %g\n", dXMin); // Print out coordinate
    printf("  Check X min value by Matrix:Set Dimensions menu command if it is %e.\n",dXMin);
}

Remark

In addition to the values displayed in the cells of an internal Origin matrix (nominally Z values), Origin matrices map X coordinate values to the columns and Y coordinate values to the rows of the matrix. The SetXMin function sets the X coordinate associated with the leftmost column of the matrix.
