S E C T I O N H .3                                            Implementation Notes



8.4.5, “Annotation Types” (Polygon and Polyline Annotations)
  91. The PDF Reference fifth edition (PDF 1.6) erroneously omitted the IT en-
      try from the additional entries specific to a polygon or polyline annota-
      tion. This entry specifies the intent of the annotation. (see Table 8.29).


8.4.5, “Annotation Types” (Text Markup Annotations)
  92. In Acrobat 4.0 and later versions, the text is oriented with respect to the
      vertex with the smallest y value (or the leftmost of those, if there are two
      such vertices) and the next vertex in a counterclockwise direction, regard-
      less of whether these are the first two points in the QuadPoints array.


8.4.5, “Annotation Types” (Ink Annotations)
  93. Acrobat viewers always use straight lines to connect the points along each
      path.


8.4.5, “Annotation Types” (File Attachment Annotations)
  94. Acrobat 7.0 and earlier viewers only support file attachment annotations
      whose referenced file is embedded in the PDF document.
  95. Acrobat 7.0 does not include a Desc entry in file specifications for file at-
      tachment annotations and ignores them if they are present.
  96. PDF 1.7 added the ability to apply markup annotations to 3D views. Al-
      though Acrobat 7.0 officially supports PDF 1.6, Acrobat 7.0.7 also sup-
      ports this feature.


8.4.5, “Annotation Types” (Watermark Annotations)
  97. Watermark annotations are handled correctly only when Acrobat n-up
      printing is selected. Selecting n-up from within the printer driver does not
      produce correct results.


8.5.2, “Trigger Events”
  98. In PDF 1.2, the additional-actions dictionary could contain entries named
      NP (next page), PP (previous page), FP (first page), and LP (last page). The
      actions associated with these entries were never implemented; beginning
      with PDF 1.3, these entries are obsolete and should be ignored.
