8、在工具箱里选择空心矩形工具，在文字周围拖拽出合适的正方形，选择矩形选项工具调整文字的整体位置。

/iknow-pic.cdn.bcebos.com/342ac65c1038534310c7db909d13b07eca808873"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/342ac65c1038534310c7db909d13b07eca808873?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/342ac65c1038534310c7db909d13b07eca808873"/>

10、找到五笔形输入法，在输入框中输入“wxzy”，然后点击注册按钮。

/iknow-pic.cdn.bcebos.com/4e4a20a4462309f75533f1a37c0e0cf3d7cad627"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/4e4a20a4462309f75533f1a37c0e0cf3d7cad627?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/4e4a20a4462309f75533f1a37c0e0cf3d7cad627"/>

11、启动word，在空白文档中，切换到五笔输入法，输入“wxzy”。

/iknow-pic.cdn.bcebos.com/d4628535e5dde71183731e47a9efce1b9c1661d9"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/d4628535e5dde71183731e47a9efce1b9c1661d9?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/d4628535e5dde71183731e47a9efce1b9c1661d9"/>

12、就出现了刚才创作的个性签名，将文字放大进行查看，也可以设置文字的颜色为红色，这样个性化的签名就制作完成了。

/iknow-pic.cdn.bcebos.com/64380cd7912397dd5259c7b55782b2b7d0a2875b"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/64380cd7912397dd5259c7b55782b2b7d0a2875b?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/64380cd7912397dd5259c7b55782b2b7d0a2875b"/>

手写版电子签名制作的方法如下：

工具／原料：戴尔G3、Win10、office365

1、将自己的纸质版手写签名插入到word中。

2、点击图片，点击上方的”格式“再点击”颜色“。

3、在重新着色框中选择”黑白50%“。

4、我们就可以得到一张白底签名了。

5、再点击颜色，找到”设置透明色“按钮。

6、点击签名图片的白色部分后，调整图片的大小与位置使用即可。
