Constructor Details

LineDashPattern

             public LineDashPattern
             (com.itextpdf.kernel.pdf.PdfArray dashArray, float dashPhase)
            

Creates new LineDashPattern object.

Parameters:

dashArray - The dash array. See getDashArray()

dashPhase - The dash phase. See getDashPhase()

Method Details

getDashArray

             public com.itextpdf.kernel.pdf.PdfArray getDashArray()
            

Getter for the dash array.

The dash array’s elements is number that specify the lengths of alternating dashes and gaps; the numbers are nonnegative. The elements are expressed in user space units.

Returns:

The dash array.

setDashArray

             public void setDashArray
             (com.itextpdf.kernel.pdf.PdfArray dashArray)
            

Setter for the dash array. See getDashArray()

Parameters:

dashArray - New dash array.

getDashPhase

             public float getDashPhase()
            

Getter for the dash phase.

The dash phase shall specify the distance into the dash pattern at which to start the dash. The elements are expressed in user space units.

Returns:

The dash phase.

setDashPhase

             public void setDashPhase
             (float dashPhase)
            

Setter for the dash phase. See getDashArray()

Parameters:

dashPhase - New dash phase.

isSolid

             public boolean isSolid()
            

Checks whether the dashed pattern is solid or not. It's solid when the size of a dash array is even and sum of all the units off in the array is 0. For example: [3 0 4 0 5 0 6 0] (sum is 0), [3 0 4 0 5 1] (sum is 1).

Returns:

is the dashed pattern solid or not

applyDashPattern

             public static com.itextpdf.kernel.geom.Path applyDashPattern
             (com.itextpdf.kernel.geom.Path path, LineDashPattern lineDashPattern)
            

Apply a LineDashPattern along a Path

Parameters:

path - input path

lineDashPattern - input LineDashPattern

Returns:

a dashed Path
