Python Dynamic Images: Create GIFs with Code

To create dynamic images, Python’s PIL (also known as Pillow) library and OpenCV library can be used to manipulate images.

Here is an example code using PIL library to create dynamic images.

from PIL import Image, ImageSequence

# 创建一个新的动态图片
new_image = Image.new("RGBA", (500, 500), (0, 0, 0, 0))

# 打开多个静态图片文件
image_files = ["image1.png", "image2.png", "image3.png"]
frames = []
for file in image_files:
    image = Image.open(file)
    frames.append(image)

# 将多个静态图片依次添加到动态图片中
new_image.save("animated_image.gif", save_all=True, append_images=frames, loop=0, duration=500)

This code segment begins by using the Image.new() function to create a new dynamic image, specifying the dimensions and background color of the image.

Then, multiple static image files are opened using the Image.open() function, creating a collection of image frames called frames.

Finally, calling the new_image.save() function will sequentially add multiple static images to the dynamic image, and save it as a single dynamic image file. The parameters save_all=True indicates saving all frames, append_images=frames means adding all frames to the dynamic image, loop=0 represents looping the playback, and duration=500 indicates each frame will last for 500 milliseconds.

It’s important to note that when saving as a dynamic image format, you can choose the GIF format (with the suffix .gif) or other formats that support dynamic images, such as APNG (with the suffix .png).

Additionally, if you need to perform more complex operations on animated images, you can use the OpenCV library to read, process, and save animated images.
