Types ¶
type Meta ¶
type Meta struct {
// contains filtered or unexported fields
}
Meta is a single key/value metadata field from a RAW file. Keys follow XMP namespace conventions (tiff:Make, exif:ISOSpeedRatings, etc.).
func (*Meta) MarshalJSON ¶
type RAW ¶
type RAW struct {
// contains filtered or unexported fields
}
RAW wraps a libraw data handle for decoding RAW image files.
func (*RAW) FocalLength ¶
FocalLength returns the focal length in mm.
func (*RAW) Image ¶
Image demosaics and returns the full-resolution image. This is a slow operation; use Thumbnail for quick previews.
func (*RAW) Metadata ¶
Metadata returns key/value pairs for camera info and shooting parameters. Keys follow XMP namespace conventions (tiff:Make, exif:ISOSpeedRatings, etc.) and implement the media.Metadata interface.
func (*RAW) Thumbnail ¶
Thumbnail extracts and decodes the embedded preview image. This is fast since the thumbnail is pre-rendered inside the RAW file.
func (*RAW) ThumbnailBytes ¶
ThumbnailBytes returns the raw thumbnail bytes without decoding. For JPEG thumbnails (the common case) this can be passed directly to exif.Parse to extract embedded EXIF metadata.
