exiflign

This package exposes an interface for "normalizing" JPEG images that have their orientation EXIF encoded. This library was designed for working with images uploaded from phone cameras that usually have their orientation tagged, which results in rotated/mirrored images when using the Go image/jpeg library. Supports little-endian and big-endian EXIF encodings, as well as all possible tag transformations.

Example

This package is very easy to use, but exposes lower-level functions for more control. A very basic use example:

fIn, err := os.Open("./input.jpg")
if err != nil { return err }
defer fIn.Close()

fOut, err := os.Create("./output.jpg")
if err != nil { return err }
defer fOut.Close()

err = exiflign.Normalize(fIn, fOut)
if err != nil { return err }

More control, as well as in-memory transformations, can also be performed.
