J'ai mis exactement les mêmes réglages de vectorisation d'un fichier identique dans la version 2025 et 2024 d'IIlustrator. Il y a deux différences dans le moteur de vectorisation entre les versions 2024 et 2025, "Simplifier" en version 2024 et "formes" en 2025. La différence majeure est dans le nombre de points d'ancrage, de 10210 en version 2024 à 2531 en version 2025.
>> Donc la version 2025 simplifie automatiquement sans que je puisse le gérer, en je ne retrouve pas la qualité que j'avais en version 2024.
Si quelqu'un a une idée par rapport à cela, ou une alternative encore sur la méthode de vectorisation?
Thank you @Abhishek Rao - with @Monika Gause we find out the reason was the dimension in pixels of the original file. In Illustrator 2025, 30000px height gives a awful result (see screen capture).
If you reduce the dimension, it works very well in Illustrator 2025, with 6000*24000 px

I assume that for now your only option is to keep the old version.

Thank you Monika. So we must assume Illustrator 2025 is less precise in this process. What a loss.

Bonjour, j'ai exactement le même probleme. Une énorme perte de qualité sur de la vectorisation très simple en noir et blanc.

Thanks for sharing your experience. It's definitely frustrating when an update impacts precision in vectorization! To better understand the difference, could you confirm the exact version of Illustrator 2025 being used in this comparison? Also, please confirm the details of the operating system.
Additionally, if possible, please share a sample file where you're seeing this discrepancy. It would help us test and analyze the behavior further. A screen recording demonstrating your workflow would also be valuable in pinpointing where the issue arises.
Looking forward to your update so we can investigate this together.
Abhishek

As you can see in the screenshot, I have almost 4 times as many anchor points in 2024 on the same file with the same settings.
