使用 Python 从 GIF 中提取关键帧 [英] Extract key frames from GIF using Python
问题描述
我想通过从 GIF 中提取 15 帧(最好应该是不同的)来压缩 GIF 图像.
I want to compress a GIF image by extracting 15 frames from the GIF that preferably should be distinct.
我正在使用 Python 和 Pillow 库,但在 枕头文档.我也没有找到如何从 GIF 中提取特定帧,因为 枕头限制.
I'm using Python and Pillow library and I didn't find any way to get the number of frames a GIF has in the Pillow docs. Neither did I find how to extract a specific frame from a GIF, because Pillow restricts that.
有没有办法提取帧而不用遍历每一帧呢?有没有更高级的用于 GIF 处理的 Python 库?
Is there any way to extract frames without iterating through each frame consequently? Is there a more advanced Python library for GIF processing?
推荐答案
这是@radarhere 答案的扩展,将 .gif 分成 num_key_frames
个不同部分,并将每个部分保存到新图像中.
Here is an extension of @radarhere's answer that divides the .gif into num_key_frames
different parts and saves each part to a new image.
from PIL import Image
num_key_frames = 8
with Image.open('somegif.gif') as im:
for i in range(num_key_frames):
im.seek(im.n_frames // num_key_frames * i)
im.save('{}.png'.format(i))
结果是 somegif.gif
分成 8 部分保存为 0
..7.png
.
The result is somegif.gif
broken into 8 pieces saved as 0
..7.png
.
