这个错误通常会出现在尝试以模式 "F" 保存 PNG 图像时。模式 "F" 表示浮点数像素,但 PNG 格式不支持浮点数像素。因此,你需要将图像转换为支持的模式(例如 "RGB" 或 "RGBA")才能将其保存为 PNG。以下是一个示例代码片段,可以将图像转换为 "RGB" 模式并保存为 PNG:
```
from PIL import Image
import os
import numpy as np
input_folder = 'D://with ground truth/train/disp' # 输入文件夹路径
output_folder = 'D://with ground truth/train/disp2' # 输出文件夹路径
if not os.path.exists(output_folder):
os.makedirs(output_folder)
for filename in os.listdir(input_folder):
if filename.endswith('.tif') or filename.endswith('.tiff'): # 仅对tif或tiff格式的文件进行转换
with Image.open(os.path.join(input_folder, filename)) as im:
# 将图像转换为 "RGB" 模式
im = im.convert("RGB")
# 保存为 PNG
im.save(os.path.join(output_folder, os.path.splitext(filename)[0] + '.png'))
```
