Stamp tool

Use the Stamp tool to add "rubber stamp" comments on drawings. Use the text stamp to indicate that a generated PDF is "DRAFT," "FOR REVIEW," and so on. Stamps are placed on a PDF as a markup and, as such, have editable appearance properties and show up on the Markups list.

Revu also includes a batch stamp tool for applying a stamp to multiple PDFs or pages.

  1. Go to Tools > Stamp and select the desired stamp.
  2. Click the PDF to place the stamp.

Stamps are removed like any other markup.

To remove markups from your PDF, do one of the following:

  • Select the markup on the PDF or from the Markups list.
  • Press Delete on your keyboard, or right-click and select Delete.

Locking a stamp protects it from accidental editing.

  1. Right-click the desired stamp and select Properties.

  2. In the General section of the Properties panel, enable Lock.

The topmost stamp in the Stamp menu is the default stamp and is usually the most recently used stamp.

To place the default stamp, follow these steps:

  1. Go to Tools>  Stamp and select the stamp from the top of the menu.
  2. Click within the PDF.

To make an different stamp the default, follow these steps:

  1. Place the desired stamp on a PDF (create a blank one for this purpose if necessary).
  2. Right-click the stamp and select Set as Default.
    Alternatively, select any the stamp that has been placed on a PDF, then go to the Properties panel, select the desired stamp from the Stamp Selection list and select Set as Default.

This stamp will be the default until you use another stamp.

See Editing Stamps for more information.

Stamps are saved to local or network drives as individual files, which allows you to organize large collections of stamps and make it easier to find a needed stamp.

Revu lists the stamps found in a selected folder. To change the current folder, go to Tools> Stamp > Change Stamp Folder and select the desired folder. The stamps found in the newly select folder are automatically listed in the Stamp menu.

You can also change the Stamp folder from the Properties panel (see Appearance Properties below).

Since stamps tend to be uniform across an organization, you may want to store them in a centrally located network folder (or even a set of folders). When doing this, give all users at your work location access to the network folder(s) and have them set their Stamp folders accordingly. As new stamps are added, they'll become available on all users' computers.

Attach a note to nearly any markup that does not have a text box of its own by double-clicking the markup to open the Note pop-up window. Notes attached to markups are functionally similar to the Note Tool.

You can add an action to almost any markup. Right-click the markup and select Edit Action.

Select a markup to reveal its control handles. Each handle controls a different aspect of size and orientation.

Rotate the markup: Drag the orange handle outside the markup (default: 15° increments; hold Shift for 1° increments)

The rotation can also be entered in the Rotation field found in the Layout section of the Properties panel.

To resize the markup, drag the appropriate yellow handle.

See Editing Markups for more information.

You can change the appearance of a Stamp markup, including its border and fill color, opacity, line width and style, and its blend mode.

To change the appearance of a Stamp markup, select the markup and select the Properties panel. Go to Window > Panels > Properties to show the Properties panel if it is hidden. Several properties will also be available on the Properties toolbar when the markup is selected.

Color: Sets the border color of the stamp.

Fill Color: Sets the background color of the stamp.

Change Color: Launches the Color Processing dialog to change the stamp colors.

Opacity: Sets the opacity of the stamp as a percent, where 100% is completely opaque and 0% is completely transparent.

Blend Mode: Defines the method by which the color in the stamp blends with the underlying PDF content.

Revu supports the standard PDF blend modes. Each is described below, as per the "PDF Blend Modes: Addendum" to the PDF Reference, fifth edition, version 1.6.

Normal: Selects the source color, ignoring the backdrop.

Multiply: Multiplies the backdrop and source color values. The result color is always at least as dark as either of the two constituent colors.

Screen: Multiplies the complements of the backdrop and the source color values, then complements the result. The result color is always at least as light as either of the two constituent colors.

Overlay: Multiplies or screens the colors, depending on the backdrop color. The colors overlay the backdrop while preserving its highlights and shadows. The backdrop color is not replaced but is mixed with the source color to reflect the lightness or darkness of the backdrop.

Darken (default): Selects the darker of the backdrop and source colors. The backdrop is replaced with the source where the source is darker; otherwise, it is left unchanged.

Lighten: Selects the lighter of the backdrop and source colors. The backdrop is replaced with the source where the source is lighter; otherwise, it is left unchanged.

Color Dodge: Brightens the backdrop color to reflect the source color. Painting with black produces no changes.

Color Burn: Darkens the backdrop color to reflect the source color. Painting with white produces no change.

Hard Light: Multiplies or screens the colors, depending on the source color. The effect is similar to shining a harsh spotlight on the backdrop.

Soft Light: Darkens or lightens the colors, depending on the source color value. The effect is similar to shining a diffused spotlight on the backdrop.

Difference: Subtracts the darker of the two constituent color. Painting with white inverts the backdrop color; painting with black produces no change.

Exclusion: Produces an effect similar to that of the Difference mode but lower in contrast. Painting with white inverts the backdrop color; painting with black produces no change.

Luminosity: Creates a color with the luminosity of the source color and the hue and saturation of the backdrop color. This produces an inverse effect to that of the Color mode.

Hue: Creates a color with the hue of the source color and the saturation and luminosity of the backdrop color.

Saturation: Creates a color with the saturation of the source color and the hue and luminosity of the backdrop color. Painting with this mode in an area of the backdrop that is a pure gray (no saturation) produces no change.

Color: Creates a color with the hue and saturation of the source color and the luminosity of the backdrop color. This preserves the gray levels of the backdrop and is useful for coloring monochrome images or tinting color images.

Line Width: Sets the stamp border thickness (in points).

Style: Determines the stamp border pattern.

Stamp Selection: Shows the path to the current Stamps folder in the first field followed by a list of the stamps found within it in the list box below. To change to a different folder, select  to the right of the current folder path and set the new folder.

Add: Opens the Create Stamp dialog to start the stamp creation process. See Creating a New PDF Stamp for more information about creating PDF stamps.

Modify: Opens the stamp so you can edit it.

Delete: Permanently deletes the stamp from the Stamps folder.
