#CONVERT IMAGE FORMAT WITH PYTHON CODE#
Import Path from pathlib : from pathlib import Path. Python code to convert images from one format to another like png->jpg. The ‘nimg’ variable stores the conversion of the image in a numpy array. Create a convert.py file within the webp folder. The error is caused by the inconsistency between PNG and JPG image modes. import cv2 import numpy as np from PIL import Image pim Image.open ('testimg.png') nimg np.array (pim) ocvim cv2.cvtColor (nimg, cv2.COLORRGB2BGR) fnam 'opencv image.png' cv2.imwrite (fnam, ocvim) Here ‘pim’ variable stores the image.Raise OSError(f"cannot write mode as JPEG") from e The above exception was the direct cause of the following exception:įile "D:\Work\-example-code\PythonExampleProject\com\dev2qa\example\code_learner_dot_com_example\pillow_example.py", line 94, in įile "D:\Work\-example-code\PythonExampleProject\com\dev2qa\example\code_learner_dot_com_example\pillow_example.py", line 88, in pillow_save_method_exampleįile "C:\Users\Jerry\anaconda3\Lib\site-packages\PIL\Image.py", line 2151, in saveįile "C:\Users\Jerry\anaconda3\Lib\site-packages\PIL\JpegImagePlugin.py", line 613, in _save Traceback (most recent call last):įile "C:\Users\Jerry\anaconda3\Lib\site-packages\PIL\JpegImagePlugin.py", line 611, in _save
The following errors will occur when you use the save() method directly.The image data (as per the camera doc) is 12 bit, little-Endian order with a Bayer pattern. Processing these type of data is new to me and I don't quite understand the logic yet. For example, if you save a PNG format image to a JPG format file like the below source code. I am struggling with processing a raw image with Python to convert it to png format.
