// Package webp implements a decoder for WEBP images.
|
||
|
|
//
|
||
|
|
// WEBP is defined at:
|
||
|
|
// https://developers.google.com/speed/webp/docs/riff_container
|
||
|
|
//
|
||
|
|
// It requires Go 1.6 or later.

// This blank Go file, other than the package clause, exists so that this
|
||
|
|
// package can be built for Go 1.5 and earlier. (The other files in this
|
||
|
|
// package are all marked "+build go1.6" for the NYCbCrA types introduced in Go
|
||
|
|
// 1.6). There is no functionality in a blank package, but some image
|
||
|
|
// manipulation programs might still underscore import this package for the
|
||
|
|
// side effect of registering the WEBP format with the standard library's
|
||
|
|
// image.RegisterFormat and image.Decode functions. For example, that program
|
||
|
|
// might contain:
|
||
|
|
//
|
||
|
|
// // Underscore imports to register some formats for image.Decode.
|
||
|
|
// import _ "image/gif"
|
||
|
|
// import _ "image/jpeg"
|
||
|
|
// import _ "image/png"
|
||
|
|
// import _ "golang.org/x/image/webp"
|
||
|
|
//
|
||
|
|
// Such a program will still compile for Go 1.5 (due to this placeholder Go
|
||
|
|
// file). It will simply not be able to recognize and decode WEBP (but still
|
||
|
|
// handle GIF, JPEG and PNG).
