Shift and Align PDF Page Content with AutoPageX™
In this tutorial, we look at how to carry out a “Shift and Align Page Content” procedure with the AutoPageX™ plug-in. Using this feature, page content such as text, images, graphics, forms and annotations can be shifted from their original position and moved to a different location. This tool provides various alignment options such as: center of the page, or one of the four page corners/edges. To demonstrate, we will use a single-page PDF file containing page content in only one specific area of the page. We will realign this content to the center of the page, and shift it upwards:
You need a copy of Adobe® Acrobat® along with the AutoPageX™ plug-in installed on your computer in order to use this tutorial. Both are available as trial versions.
Step 1 - Open the Tool
With the PDF containing the content that you want to align/shift open in Acrobat, select "Plug-Ins > AutoPagex Plug-in > Shift and Align Page Content...".
Step 2 - Select How To Align Content
Choose an option using the "Align page content:" drop-down menu. In this example, content will be aligned with the "Center of the page" - but you can pick from various anchor points.
The software identifies the page content, computes the 'extents' (outmost edges) of it, and automatically shifts its location according to the selected alignment position. Using the center of the page means that the center-point of the content’s extents is moved to the center of the page. Using either page corner option means that this ‘corner’ of the page content is aligned with the corresponding corner of the page (i.e.: the bottom left corner of the content is aligned with the bottom left corner of the page; the bottom right corner of page content is aligned to the bottom right corner of the page, and so on.)
Step 3 - Optional: Shift Page Content
After performing an alignment operation, page content can also be shifted. Check the "Shift page content" option to enter page shift parameters. Four different measurement units can be used to specify horizontal and vertical offsets: millimeters, centimeters, inches and points (1/72 inch).
Select an option from the "Units:" drop-down list, and enter values to shift page content by in the horizontal/vertical offset entry boxes. In this example, after aligning content with the centre of the page, it will be shifted 4 inches upwards "vertically".
Step 4 - Select Pages for Processing
Use the lower section to configure a processing page range. In this example, we will process "All pages of the document", but it's also possible to process only the currently open page or a specific range of pages. Optionally use the "Subset" drop-down menu to process only odd or even pages of the document. By default, "All Pages" will be processed.
Press "OK" to continue using the current settings.
Step 5 - Inspect the Results
Check that page content has been correctly aligned and shifted. In this example, the page content has been made central, then raised up higher:
Use negative values with the "Shift page content" feature (step 3) to move content down/left. For example, the sample below shows page content moved vertically upwards by 6 inches, then moved to the right (2 inches) and left (-2 inches).
