The digital signature of FineReaderPDF 15 software can also identify some pictures, and its function is somewhat similar to a quick screenshot. When our computer doesn't download the screenshot tool, we can use it to take screenshots directly on the software.

Click the digital signature icon, or use the mouse to select the location where we want to take a screenshot, drag the mouse and click Copy Image. After waiting for a period of time, the pictures in the pdf document will be copied. We can directly press ctrl and V to paste the picture anywhere we want.
