Dropzone HEIC 图像上传为 JPG 时无法保存
我正在使用 Dropzone 进行图像上传。如果上传 HEIC 图像，我使用 heic2any 使用以下代码转换文件： https://github.com/dropzone/dropzone/issues/1984#issuecomment-886460171。我检查file.type，如果它是image/heic，我就会进行转换。它非常适合我笔记本电脑上的 HEIC 图像，即上传的图像被识别为 HEIC 图像并成功转换和保存。
问题是从 iPhone 上传 HEIC 图像。当收到图像时，它是一个image/jpeg，因此我不使用heic2any 对其进行转换。看来如果上传的 HEIC 图像很小，无需 heic2any 即可成功转换为 JPEG。但是，以 JPG 形式接收的较大 HEIC 图像无法成功保存。如果从笔记本电脑上传较大的 HEIC 图像，它确实可以工作，因为它被识别为 image/heic 并命中 heic2any 代码。
对于如何处理从 iPhone 上传的较大 HEIC 图像有什么建议吗？这些图像以某种方式转换并以 JPEG 形式接收，没有经过 heic2any 但没有保存？
I'm using Dropzone for image uploads. If a HEIC image is uploaded I use heic2any to convert the file using this bit of code: https://github.com/dropzone/dropzone/issues/1984#issuecomment-886460171. I check the file.type and if it is an image/heic I do the conversion. It works great for a HEIC image on my laptop namely the uploaded image is recognized as a HEIC image and is successfully converted and saved.
The issue is uploading a HEIC image from the iPhone. When the image is received, it is a image/jpeg and therefore I don't convert it with heic2any. It seems if the uploaded HEIC image is small, it gets converted to a JPEG successfully without heic2any. However, larger HEIC images that are received as a JPG aren't successfully saved. If the larger HEIC image is uploaded from the laptop it does work since it's recognized as a image/heic and hits the heic2any code.
Any suggestions for how to handle larger HEIC images uploaded from a iPhone that are somehow converted and received as a JPEG having not gone through heic2any but are not saving?
