When I click on the image>property>details of a PNG image in Windows many fields are missing compared to a JPEG file. Are these fields supported in PNG? If so, how would they be added in a PNG file programmatically?

推荐答案

PNG没有EXIF块.因此，如果您将JPEG转换为PNG，则EXIF元数据将会丢失.

PNG has no EXIF chunk. Thus EXIF metadata will get lost if you convert from JPEG into PNG.

但是，Adobe已经制作了 XMP 用于存储各种元数据.这样，您就可以在保留元数据的同时在JPEG和PNG之间进行转换.

However Adobe has made XMP for storing all kinds of metadata. So that you can convert between JPEG and PNG while preserving metadata.
