Secondly, I uploaded my signature picture to the local computer. The uploaded signature effect display is still in picture format.
3. Next, click to select a picture, and then click "Format"-"Color" in the toolbar. In the color drop-down menu, we can recolor the picture to make the signature lines clearer and fuller.
4. Then, after coloring, click "Set Transparent Color" in the dialog box. At this time, the mouse pointer will change to a pen shape, click on the signature picture, and the background will be removed.
5. The last step is to drag the signature to the appropriate position and size, and double-click the blank area of the table, so that the signature will be added to the table.
