Class PDFShapeCmd

  • public class PDFShapeCmd
extends PDFCmd
    Encapsulates a path. Also contains extra fields and logic to check for consecutive abutting anti-aliased regions. We stroke the shared line between these regions again with a 1-pixel wide line so that the background doesn't show through between them.

      • execute

        public java.awt.geom.Rectangle2D execute​(PDFRenderer state)
        perform the stroke and record the dirty region
        Specified by:
        execute in class PDFCmd
        Parameters:
        state - the current graphics state; may be modified during execution.
        Returns:
        the region of the page made dirty by executing this command or null if no region was touched. Note this value should be in the coordinates of the image touched, not the page.
