Question

我正在将gif转换为图像序列，并且可以正常工作，但是我想调整图像的大小然后保存它们，我输入最大宽度和高度，并计算出比例，然后调整图像的大小，但是图像是和以前一样，这是我的代码：

from PIL import Image, GifImagePlugin

imageObject = Image.open("my.gif")

print(imageObject.n_frames, 'frames')
print(imageObject.size)

count = 1
max_wh = 300 #the maximum height and width
width, height = imageObject.size
ratio = min(max_wh/width, max_wh/height)

print(height, width, ratio, int(width*ratio))

for frame in range(0,imageObject.n_frames):
    imageObject.seek(frame)
    imageObject.resize((int(width*ratio), int(height*ratio)), Image.ANTIALIAS)
    imageObject.save(f'a_{count}.png')
    count += 1

来自Pillow documentation：

<块引用>

Image.resize(size, resample=3, box=None, reduction_gap=None)

返回此图像的调整大小副本。

from PIL import Image, GifImagePlugin

imageObject = Image.open("my.gif")

print(imageObject.n_frames, "frames")
print(imageObject.size)

max_wh = 300 # the maximum height and width
width, height = imageObject.size
ratio = min(max_wh/width, max_wh/height)

print(height, width, ratio, int(width*ratio))

for frame in range(0, imageObject.n_frames):
    imageObject.seek(frame)
    # Image.resize() returns a resized copy of the original
    resized = imageObject.resize((int(width*ratio), int(height*ratio)), Image.ANTIALIAS)
    resized.save(f"a_{frame}.png")

为什么无法调整枕头中图像的大小？
