• func DetectImage(data []byte) string
• func DetectImageStream(fp io.ReadSeeker) (string, error)

Functions ¶

func DetectImage ¶

func DetectImage(data []byte) string

DetectImage detects the image type of the data.

It's a copy of http.DetectContentType with some unnecessary parts removed, making it about 10 times faster.

It returns an empty string if the image type can't be determined.

func DetectImageStream ¶

func DetectImageStream(fp io.ReadSeeker) (string, error)

DetectImageStream works like DetectImage, but operates on a file stream.

It reads the minimal amount of data needed and Seek() back to where the offset was.
