用烘焙数据解析PNG图像

Question

I know there is an image package that exist in Golang that implements encode and decode functionality, but how can I get other data from an image?. For example I am trying to get iTXt chunks from PNG images, is there any way I can do this?

@Khalil,

Looks like Go's PNG reader does not support ancillary chunks. Check internals of https://golang.org/src/image/png/reader.go for line 87 and compare with https://www.w3.org/TR/PNG/#5ChunkOrdering.
