Brief introduction of trimming image size:
Step 1: Open the picture (the size of the picture can only be changed if the picture exists. How to add pictures is just a step. I believe everyone understands)
Step 2: Look at the top of the software, there is a row of icon buttons, just find the "size". If you want to cut the size of the picture, just look for "crop" (you don't have to look elsewhere as before).
Step 3: Click "Size", and then you will see a list, in which you can adjust the width, height and percentage of the picture.
After the adjustment, you can see if it is ok. In fact, as long as you find the "size", you can easily adjust it.
