1. First of all, you need to know how big the one-inch photo and the two-inch photo are. 1 inch = 2.5cm*3.5cm, 2 inches = 3.5cm*5.3cm. Then open it with Photoshop and use the magic wand tool to Cut out the character and use the deformation tool to modify it slightly to make the character look straight.
2. Copy the layer.
3. Then select the crop tool, select the size and resolution in the drop-down options at the top, and set the width to 2.5cm, the height to 3.5cm, and the resolution to 300 in the pop-up dialog box.
p>4. Press the arrow keys to adjust the picture to the appropriate position, click the "Submit current cropping operation" button in the property bar, then create a new layer at the bottom of the character layer, and fill the background color of the character with #52c8e4. In this way, the one-inch photo is ready.
5. Then format the one-inch photo, select Canvas - Canvas Size, set the width to 0.4cm, the height to 0.4cm, check Relative, set the canvas expansion color to white, and then click Edit - Define Pattern defines a picture as a pattern.
6. Then create a new canvas, set the width to 11.6cm, the height to 7.8cm, and the resolution to 300 pixels. Then select Edit - Fill, select pattern, customize pattern, and select the pattern you just saved. Finish.
