How To Copy and Re Size An Image In Adobe Acrobat
Step 1. Open your document up.
Step 2. Go to Edit on the menu and click on the "Take A Snapshot" option. (Circled in red)
Step 3. Create a "box" around the "area" that you want to re size-copy by starting in the upper left corner and click and holding down your left mouse button. Release the button once you have dragged your button around the area. It will then turn "blue" and let you know that the area you have dragged around has now been copied to your "clipboard"
Now you can open up any Word processor or other program and "paste" your selection onto the page. It will read your selection as an image and you will be able to "re-size" it.
Hope this helps you rethink how to use those PDF files.
