Delete PDF Pages

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

The Delete PDF Pages Node is a process node that can be used to delete specific pages from a PDF document. Use the node’s setting window to specify either a fixed range of or specific pages that should be deleted.

Using the Delete PDF Pages Node

Add the Delete 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 Delete 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 Delete PDF Pages Node.
• In the Description field, enter a description for the Delete 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 deleted, 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[]}.

Use this panel to specify per-page metadata features of the pages to be deleted. Each document page matching these features is deleted.

• Checkbox: To use this page, select the checkbox.

• Add new filter: Click this button to add a new per-page metadata filter. Edit this new filter by clicking on its fields.

  • Select Metadata: Click to open a Metadata browser window, in which 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.
