PDF/UA and accessibility testing

Of the 136 tests described in the Matterhorn Protocol (PDF, 340Kb), 87 may be fully automated with software. Human intervention is only required to assess and correct any errors located by software. 136 - 87 = 49

The 47 checks that may require human judgement boil down to:

Reflowing a flexible PDF file (Standard and Pro)

Let's take a quick look at how flexible a tagged PDF file is.

First, adjust the size of the document window to mimic the smaller screen of a handheld device.

  1. Choose View > Zoom > Actual Size to display the document at 100%.
  2. Resize the Acrobat window to about 50% of the full-screen display.
    • In Windows, click the Maximize/Restore Down button if the window is currently maximized; if the window isn’t maximized, drag a corner of the application window to reduce it. In Mac OS, resize the document pane by dragging a corner. Your goal is to resize the Acrobat window so that the ends of the sentences in the document pane are cut off.
  3. Choose View > Zoom > Reflow.
  4. The content of the document is reflowed to accommodate the smaller document screen, and you can now read an entire line of text without using the horizontal scroll bar.
    • When you reflow text, artifacts such as page numbers and page headers often drop out because they are no longer relevant to the page display. Text is reflowed one page at a time. You cannot save the document in the reflowed state. Now you’ll examine how the display changes when you change the magnification.
  5. Choose 400% from the magnification menu in the Page Controls toolbar.
  6. Scroll down the page to see how the text reflows.
    • Again, because the text is reflowed, you don’t have to use the horizontal scroll bar to move back and forth across the page to read the enlarged text. The text is automatically contained within the document pane.

When you’ve finished viewing the reflowed text, restore the Acrobat document window to its usual size,
