Shift PDF Pages Node

Note: This node works with PDF files (version 1.3 or later).

The Shift PDF Pages Node is a process node that can be used to shift the content of pages in a PDF document. Use the node’s setting window to specify which pages are shifted and by how much they should be moved.

Using the Shift PDF Pages Node

Add the Shift PDF Pages Node to the workflow by dragging the node’s icon onto the Workflow Builder canvas, and then double-clicking on the icon to open the Shift PDF Pages Node’s window:

  • Select the Enabled checkbox so that the process will run. When unchecked, this process is ignored. Documents pass through as if the node were not present (i.e., continue along the default or positive path). Note that a disabled node will not check for logic or error conditions.
  • In the Node Name field, enter a meaningful name for the Shift PDF Pages Node.
  • In the Description field, enter a description for the Shift PDF Pages. This is not required, but can be helpful with multiple collection points. If the description is long, hover the mouse over the field to read its entire contents.
  • Select the Save button to apply the settings. Select the Cancel button to exit the window without saving any changes.
  • Select the Help button to access online help.

Page Filter

In this panel, specify the pages to be shifted, based on ordinance, ranges or per-document metadata properties.

  • Page Filter: Choose one of the pre-defined page filters from the drop-down menu. The supported options are: All, First, Last, Odd, Even, and Custom.

    If Custom is chosen, the Page Range input field appears. Use the field to enter a custom range of page numbers. Both comma-separated values and ranges (e.g., 3-5 instead of 3,4,5) are accepted. A maximum of 100 characters may be entered in the field.

    Note: The page number must not be greater than 2147483647.

  • Page Filter from Metadata: Use this option to select pages to process based on document-level metadata. Click on the Metadata Button (see below) to open the metadata browser.

    Note: The result of the entered metadata expression must be a Custom Page Filter (see above), i.e. a string containing one or more comma-separated, single page numbers (e.g. 2) or page ranges (e.g. 3-5).

  • Metadata Button: Click to open a Metadata browser window. Either a metadata key or a custom string value may be entered. To select a metadata key, double-click on it, and then click on the Select button to apply the metadata key.

    All Metadata syntax specified in the Help topic Metadata Reference Information may be used. For example, if there are multiple document-level values containing page numbers for the metadata key {data:page}, use {data:page[]|,} as the page filter from metadata to concatenate them with commas in order to generate a valid page filter. For a single value, use {data:page[]}.

Position Values

In this panel, the new page position may be entered using fixed values or by using metadata.

  • Measurement in: Use the drop-down to choose one of the three measurement units: PDF units, inches, or mm.

  • Fixed Values: The target values for the new position can be directly input into the following fields. The offset values may be positive or negative. There are no upper or lower limits.

    • Shift Right: Enter the number of measurement units the page contents are shifted right. To shift left, use negative numbers.

    • Shift Up: Enter the number of measurement units the page contents are shifted up. To shift down, use negative numbers.

    Note: Shifting the page contents too far can lead to empty pages in the output document since the Shift PDF Pages Node does not alter the current Page Height or Page Width.

  • Values from Metadata: The Shift Right and Shift Up parameters may also be derived from page-level metadata. To support this option, there are two metadata buttons in the Position Values panel:

    • Right Value from Metadata button: Click on this button to open a Metadata browser window. Select either a metadata key by double-clicking on it, or type in a custom string. The metadata information is then used for the new Right value.

    • Up Value from Metadata button: Click on this button to open a Metadata browser window. Select either a metadata key by double-clicking on it, or type in a custom string. The metadata information is then used for the new Up value.

    If incorrect metadata is selected or entered manually, the workflow will still run, but the pages will not be shifted. In such cases, a warning/error message is added to the Dispatcher Phoenix’s error log.
