Class HelveticaMetrics

  • public final class HelveticaMetrics
extends java.lang.Object
    Character advance widths (per 1000 text-space units, i.e. AFM/PDF glyph metric convention) for the standard 14 font Helvetica, covering ASCII 0x20-0x7E. These are the standard, freely-republished Adobe Core 14 AFM numbers (the same table every PDF library, including PDFBox, ships) -- metric data, not copyrightable expression. Useful whenever code building a COS content stream (an annotation appearance, a signature's visible appearance, ...) needs to word-wrap text without embedding a font program; characters outside this range fall back to the (also standard) 556 average width.
