One of them is the feature to give a user, using an ordinary PDF reader, the ability to import their own image into a form. Usually this would be for a character portrait. Here’s how you can add that. You’ll need a PDF editor that lets you create and edit forms.
- Open the PDF in an editor that will let you create PDF forms. I use Adobe Acrobat Pro
- Open Form Editing mode
- Create a form button control where you want the image to appear
- Select the Properties of the button.
- Set the Border Color and Fill Color dropdowns to No Color on the Appearance Tab. This will make the box invisible except for the image.
- Set the Layout dropdown to Icon Only on the Options Tab
- On the Actions tab, Choose Mouse Up on the Select Trigger dropdown box
You can now click OK and save the form. Whenever the form is opened in a form-compatible PDF reader, a user can click on that area, and a dialog will appear to let the user import the image of their choice.
Alternately, you can just download one of the many character sheets I’ve designed and just copy the image box I used. All of them are named Portrait. You can copy and paste it directly onto your PDF form.
