Problem Description
When using PIL to read an image and then resize it, a PIL version problem occurs. AttributeError: module 'PIL.Image' has no attribute 'ANTIALIAS'
The specific code is as follows
image = image.resize((scaled_width, scaled_height), Image.ANTIALIAS)
Cause Analysis
In the new version of pillow (after 10.0.0) Image.ANTIALIASit has been removed and replaced by Image.LANCZOSor Image.Resampling.LANCZOS. The relevant description can be found in the release notes of pillow .
More ways to be removed are as follows
| Removed | Use instead |
|---|---|
| Image.LINEAR | Image.BILINEAR or Image.Resampling.BILINEAR |
| Image.CUBIC | Image.BICUBIC or Image.Resampling.BICUBIC |
| Image.ANTIALIAS | Image.LANCZOS or Image.Resampling.LANCZOS |

Back to the question just now
solution
The solution to the problem just now is to Image.ANTIALIASreplace with Image.LANCZOSor Image.Resampling.LANCZOS
the modified code is as follows:
image = image.resize((scaled_width, scaled_height), Image.LANCZOS)
The above only records the following problems I encountered during the debugging process to facilitate subsequent modification of similar programs.
