Editing
When the "Edit" button is clicked in the Viewer window the Edit window is launched.
There are three tabs available in Edit mode - Thumbnails, Mark-Ups and Bookmarks. Each tab shows a different view and allows different edit operations to be performed. Either the toolbar or the menu items File, Pages, Bookmarks, Rotate and Tools can be used to perform edit operations.
When you have finished editing the document you must save the document. When you close the Edit window the modified document will be displayed in the Viewer window.
In Edit mode there are a number of different operations that can be performed:
Thumbnail View
The left hand side contains thumbnail images of every page in the document. The right hand side shows the current page.
Add/Remove/Rearrange Pages
You can rearrange the order of pages by selecting thumbnails and dragging them into the correct
position. You can delete pages by selecting a thumbnail and pressing the delete key. You can insert or append pages using the pages menu. You can split a PDF into multiple PDFs.
Bookmark View
You can move bookmarks around by the "drag and drop" method. If you right click on a bookmark, you will see a menu of options for adding, deleting and changing bookmarks.
By default, the bookmark is placed at the top left of the chosen page. You can use the Select Bookmark Destination menu item to select a point on the PDF other than the top left of the page.
Mark-up View : Drawing Tools
Typewriter Text, Text Box, Oval Text, Arrow, Line shapes can be draw on the PDF. To so so, click on the desired tool in the Drawing tools panel then left click on the page view and drag the object to the desired shape by holding the left mouse button down.
The attributes of the object can then be adjusted by clicking on the remaining controls in the Drawing Tools panel.
Mark-up View : Sticky Notes / Comments
Sticky notes are little windows on the PDF page that contain text. The windows can collapse or appear by double clicking on the icon. A variety of icons are supported.
Mark-up View : Custom Stamps
These are text boxes that can be placed on top of the PDF content. They can be resized and rotated. You can add your own strings by typing in the 'stamp text' field. Gradient style fills are supported. Click here to watch a video tutorial.
| Stamp Text | This is the text that appears as the watermark. There are 14 standard text strings,
however you can add your own, just by typing in this combo box. Your customized strings will be remembered at the
start of the list.
Sophisticated tags and control characters to include things as timestamps, auto incrementing numbers, document name and environment variables can be inserted. |
| - | This button will remove the current selection in Stamp Text from the list of available
stamps. Only stamps that were not provided by default with pdfMachine can be deleted.
|
| Insert | When clicked the text in 'stamp text' will appear in a new stamp in the middle of the
current page.
|
| Insert on all pages | If clicked then the stamps will appear on every page of the document.

attributes.

Mark-up View : Insert Media / Attach Files
This view allows insertion of sounds, images or files for embedding within the PDF.
| Insert Image | When clicked, a file selection dialog appears. When a bitmap file is selected it is
automatically placed into the centre of the current page where it can be resized and moved.
|
| Record / Insert Sound | When clicked, the following dialog appears:
If a microphone is present then recording begins when "start recording" is clicked. Alternatively, a previously recorded file can be selected with the "browse" button. Most WAV files are supported. When "insert into PDF" is clicked, the dialog is closed and a sound icon is inserted into the middle of the current page. When the sound icon is double clicked, the sound is played. 
|
| Attach Files | When clicked, displays a dialog for attaching and removing embedded files within the current
PDF.

Mark-up View : Redaction
Redaction allows you to permanently remove text and images from the PDF, replacing them with colored blocks. The information is removed, not just hidden. Redaction provides a means to protect sensitive or confidential information.
Once "start redact" is clicked, redact mode is entered. You can then "draw" redact rectangles on the document. Once "apply redactions" is hit (or the document is saved) the redact rectangles are "burnt in" to the document, removing all content behind them. Each page that contains a redaction is converted to an image to ensure 100% redaction. You can use the color selection tool to change the color of the redact blocks. Click here for a video tutorial.

| Set Crypto Password | This is a pdfMachine ultimate feature, optionally used for signing PDFs where a password
is required to access the private key. If set, pdfMachine will remember this password and use it when required, so
you dont have to enter it each time.
This is particularly useful when doing a batch job consisting of a lot of signed PDFs. e.g. pdfMachine word merge that produces 1000 signed PDFs. If you change the password outside of pdfMachine, you will have to redo it here. If you set the password to a blank string, it will clear the remembered password and you will have to enter it each time you sign a PDF. For details on digital signatures click here. |
