What Is Markup?

To let Redax know that you want to redact a specific piece of information, such as an image or a segment of text, you mark it by putting a Redax box around it. A Redax box is one type of Redax markup. Redax markup is different from Acrobat markup, which can be a Highlight, Underline, Cross Out (Strikethrough) or Acrobat Redaction.

types of markup

Redax provides many methods for marking up documents. In the following sections, you will learn two of these methods, one for marking up images and the other for marking up text.

Marking Up Images

To mark an image for redaction, you must manually draw a Redax box around it with the Draw Box tool. In the following exercises, you will mark up two images in sample_base.pdf:

The only bitmap image in the document, is on page 3.

bitmap image. One of two major graphic types, also called a raster image. (The other type is a vector graphic). Bitmap graphics are made up of individual pixels or dots, each of which is assigned a color. Digital photographs and scanned pages are examples of bitmap graphics.

The vector image is on page 18, which you printed when you evaluated sample_base.pdf.

Note: When you evaluated sample_base.pdf, a Redax box was drawn around the graphic on page 3, which might lead you to believe it is a vector image. However, only the border is in vector format. The graphic itself is a bitmap image.

To mark the bitmap image on page 3

  1. Open sample_base.pdf and go to page 3.

  2. Examine the image to plan your markup. For this exercise, you will draw a Redax box around the center of the image, just to cover the burglar. When you redact the document, only the burglar will be removed from the image.

  3. Select Redax > Draw Box to check the Draw Box tool. The pointer changes to a crosshair.

    Note: If the pointer doesn’t change to a crosshair, repeat this step. The Draw Box tool is like a toggle switch. It is either on or off. If it was on to begin with, selecting Redax > Draw Box would have turned it off.

  4. Position the pointer where you want to begin drawing, press the left mouse button, and drag to draw your box.

    Release the mouse button when you are satisfied.

    The box changes to the color you specified in the Redax Menu > Redax Preferences > Redax Box Preferences > Box Color.

  5. Select Redax > Show/Hide and then check the US FOIA box. Repeat to display the US Privacy palette. If US FOIA and US Privacy do not appear under the Show/Hide submenu, click on Display All Palettes and both palette windows will display.

    (In the sample screen below, the Redax box is red; yours may be a different color).

    exemption code palette. A set of available exemption codes. Two exemption code palettes are supplied with Redax, one for FOIA (Freedom of Information Act) exemption codes and the other for Privacy Act exemption codes. The supplied palettes can be modified and new palettes can be created.

  6. In the US Privacy palette, click exemption code (b).

    The code appears in the top-left corner of the Redax box. Note that it is the same color as the Redax box.

  7. Select File > Save to save your markup.

  8. Double-click the Redax box to view its properties.

    Observe that the default Author, Note, and Box Color you defined in your Redax Box preferences are displayed.

  9. When you are finished, click OK to close the Redax Box Properties dialog box.

To mark the vector image on page 18

  1. Open sample_base.pdf and go to page 18.

  2. Look at the paths on the printout you made of the image on page 18. The following figure shows those paths.

    Vector images are marked up

  3. Figure out where you need to draw a Redax box to mark the pie chart for redaction, but none of the text surrounding it.

    Tip! It’s impossible to draw a Redax box around the whole pie chart without touching any text. But you don’t have to, because this is a vector image. Remember that marking an entire path—from start to finish—only requires that you include part of the path in your Redax box. So, you just have to draw the box so that it touches all three paths in the pie chart.

    Redact entire image by adding a box

  4. To draw the Redax box, perform steps 3–9 in the previous exercise, to mark the bitmap image.

    Note: The process of drawing a Redax box is the same for bitmap and vector images. The only difference is in where you draw the box. For bitmap images, the box must cover the area you want to redact. For vector images, it only has to touch each path you want to include in the redacted area, however, you should try to make the Redax box large enough to contain the exemption code(s).

Marking Up Text Using a Redaction List File

The quickest way to mark up text is to use a redaction list file. Use the Find Using List editor to create a list of words and phrases to be redacted, along with any exemption codes to replace the redacted text. When a redaction list file is applied to a document, all of the matching words and phrases in the document are marked with Redax boxes.

A sample redaction list created in the Find Using List editor dialog is shown below. Exemption codes are in the left column and words or phrases to be redacted appear in the right column.

Find Using List

In the following exercises, you will use sample_find_list.txt to mark up text in sample_base.pdf

To mark up text using the sample redaction list file

  1. In Acrobat, open sample_base.pdf.

    Part of page 1 from sample.pdf which contains text

  2. Select Redax > Find Using List.

  3. Click on the Import File button.

  4. In the dialog box that opens, browse to the location where the sample files reside and select sample_find_list.txt, and then click OK. The default location is C:\Appligent\Redax\Samples.

    The sample list file is loaded into the Find Using List editor dialog.

  5. Click the Find button.

    Redax searches through sample_base.pdf and adds Redax boxes to all of the areas that match the words and phrases in the list file. When it’s finished, it displays a dialog box with the number of new annotations.

  6. Click Done to close the dialog box.

The following figure shows some of the Redax boxes on the first page of sample_base.pdf:

Congratulations! You are finished marking up sample_base.pdf.

What You Learned: A Summary

In this section, you learned what Redax markup is and how it is different from Acrobat markup. You also tried two Redax markup methods on the sample file. With the first method, you marked up a bitmap image and a vector image using the Draw Box tool. With the second method, you marked up text using a redaction list file.

What Else You Need to Know

There are many ways to mark up a document for redaction, and you can use whatever combination of methods suits your needs. The Draw Box tool, which you used to mark up images in this tutorial, can also be used to mark up text. In addition, you can:

  • Use Acrobat highlighting tools (Highlight, Underline, Cross Out/Strikethrough) or Acrobat Redaction to mark up text
  • Mark an entire page or range of pages
  • Mark text that matches pre-defined patterns such as Social Security numbers, dates, email addresses and more
  • Mark text that matches regular expressions
  • Create a template and apply it to documents to mark up information that’s in the same location as it is in the template

These markup methods are described in detail in Marking Up Your Redax Document in the Redax User Guide.

When you are finished marking up a document, you should review it thoroughly to make sure the markup is correct. Redax supplies a number of tools to help you. For example, you can scroll among the pages that contain Redax boxes, skipping those that don’t. You can also create a Redax report, which catalogs every Redax box in the document. If you find a Redax box that isn’t right, you can modify it or delete it. The different ways to review and adjust your markup are covered in Reviewing Redax Markup in the Redax User Guide.
