Example 2 with PDAnnotationPolyline

use of org.apache.pdfbox.pdmodel.interactive.annotation.PDAnnotationPolyline in project pdfbox by apache.

the class PDPolylineAppearanceHandler method getLineWidth.

// TODO DRY, this code is from polygonAppearanceHandler so it's double
/**
 * Get the line with of the border.
 *
 * Get the width of the line used to draw a border around the annotation.
 * This may either be specified by the annotation dictionaries Border
 * setting or by the W entry in the BS border style dictionary. If both are
 * missing the default width is 1.
 *
 * @return the line width
 */
// TODO: according to the PDF spec the use of the BS entry is annotation
// specific
// so we will leave that to be implemented by individual handlers.
// If at the end all annotations support the BS entry this can be handled
// here and removed from the individual handlers.
float getLineWidth() {
    PDAnnotationPolyline annotation = (PDAnnotationPolyline) getAnnotation();
    PDBorderStyleDictionary bs = annotation.getBorderStyle();
    if (bs != null) {
