Image Exif

实现对JPEG文件在不进行编码下, 保留图片旋转的 EXIF 参数，但会有损 EXIF 的数据字节规范

单独获取指定 EXIF IFD 标签数据

GetDefineTag 方法能获取指定标签的数据; 当不符合指定的标签ID, 会偏移至下一个标签字节位置, 避免解析无关标签数据

图片编码应用

痛点: Go SDK 编码图片, 会丢失图片的EXIF 数据, 会引发图片旋转角度与原图不一致

解决: 获取图片旋转值后, 在对图片编码时, 使用 (imaging)[http://github.com/disintegration/imaging] 的 Rotate 设置图片旋转参数

Info

Inspired by goexif package imaging package

# Packages

Package tiff implements TIFF decoding as defined in TIFF 6.0 specification at http://partners.adobe.com/public/developer/en/tiff/TIFF6.pdf.

# Functions

No description provided by the author
Decode parses EXIF data from r (a TIFF, JPEG, or raw EXIF block) and returns a queryable Exif object.

IsCriticalError, given the error returned by Decode, reports whether the returned *Exif may contain usable information.
IsExifError reports whether the error happened while decoding the EXIF sub-IFD.
IsGPSError reports whether the error happened while decoding the GPS sub-IFD.
IsInteroperabilityError reports whether the error happened while decoding the Interoperability sub-IFD.
IsShortReadTagValueError identifies a ErrShortReadTagValue error.

# Structs

Exif provides access to decoded EXIF metadata fields and values.

# Interfaces

Parser allows the registration of custom parsing and field loading in the Decode function.
Walker is the interface used to traverse all fields of an Exif object.

# Type aliases

No description provided by the author
A TagNotPresentError is returned when the requested field is not present in the EXIF.
