如何使用静止图像制作GIF动画

Animated GIFs can be created in Photoshop by stringing together still images. This process consists of layering each frame from the bottom up and then sequencing the layers using Photoshop’s animation/timeline tool.

Step 1 — Create each layer individually in Photoshop. Run Photoshop and

• create a new image by clicking File > New and then selecting “OK.” Then
• unlock the background layer by double-clicking the lock icon,
• create a new layer by opening Layer > New… > Layer and design each frame accordingly.
• layering your animation from the bottom up.
• you may resize the newly created layers accordingly using Photoshop’s transform tool (Edit > Free transform or Ctrl + T, then drag the corners to resize the object).

Step 2 — After arranged your layers accordingly, you can began sequencing your layers. 

• access the animation window by opening Window > Timeline in Photoshop CS6  to access the Timeline window.

• Once you’ve opened Photoshop’s sequencing tool, click on small arrow in the upper-right hand corner, and then select Make Frames From Layers.

You can also click on the small arrow to create a new frame manually (or you can simply use the hot-key command Ctrl>Shift>Alt>F). From there, use the eye icon next to each layer to hide the layers you don’t want to appear in the frame you’ve created.

From here, use the menu underneath each frame to toggle its duration. The menu in the bottom left-hand corner dictates how many times your GIF will replay — set it to Forever if you want it to loop endlessly.

Step 3 — Export it out of Photoshop:

• Head for File > Save for Web. Remember to keep your GIF no larger than 1MB. If necessary, tweak the color, dither, loss, and size settings until your GIF has been resized accordingly. Then, save your newly minted GIF.
