Overview
Parse raw TIFF data.
Requirements
- Go >= 1.17: Earlier versions may work, though testing broke before due to a "undefined: unsafe.Slice" error apparently in the basic flow of "go test".

Types ¶
type TiffMediaContext ¶
type TiffMediaContext struct {
// contains filtered or unexported fields
}
TiffMediaContext encapsulates parsed EXIF data.
func (*TiffMediaContext) Exif ¶
func (tmc *TiffMediaContext) Exif() (rootIfd *exif.Ifd, data []byte, err error)
Exif is an accessor that returns the root IFD.
type TiffMediaParser ¶
type TiffMediaParser struct {
}
TiffMediaParser knows how to parse a TIFF stream.
func NewTiffMediaParser ¶
func NewTiffMediaParser() *TiffMediaParser
NewTiffMediaParser returns a new `TiffMediaParser` struct.
func (*TiffMediaParser) LooksLikeFormat ¶
func (tmp *TiffMediaParser) LooksLikeFormat(data []byte) bool
LooksLikeFormat returns a boolean indicating whether this looks like a TIFF stream.
Example ¶
filepath := getTestExifImageFilepath()
data, err := ioutil.ReadFile(filepath)
log.PanicIf(err)
pmp := NewTiffMediaParser()
isPng := pmp.LooksLikeFormat(data)
fmt.Printf("%v\n", isPng)
Output: true
func (*TiffMediaParser) Parse ¶
func (tmp *TiffMediaParser) Parse(rs io.ReadSeeker, size int) (mc riimage.MediaContext, err error)
Parse parses a TIFF stream given a `io.ReadSeeker`.
func (*TiffMediaParser) ParseBytes ¶
func (tmp *TiffMediaParser) ParseBytes(data []byte) (mc riimage.MediaContext, err error)
ParseBytes parses a TIFF stream given a byte-slice.
func (*TiffMediaParser) ParseFile ¶
func (tmp *TiffMediaParser) ParseFile(filepath string) (mc riimage.MediaContext, err error)
ParseFile parses a TIFF stream given a file-path.
