Functions ¶

func CleanStr ¶

func CleanStr(s string) string

func ExifCp ¶

func ExifCp(toolPath string, src, dst string) (string, error)

ExifCp copies exif data from src image to dst image. It excludes Orientation tag because the orientation has been normalized in the processed images.

func ExifTags ¶

func ExifTags() map[string]string

YYYY:MM:DD HH:MM:SS

func ExiftoolPath ¶

func ExiftoolPath(toolPath string) (myPath string, err error)

func ExiftoolPathFind ¶

func ExiftoolPathFind() (myPath string, err error)

ExiftoolPathFind searches PATH for exiftool and returns the absolute path to it if found.

func ExiftoolPathValidate ¶

func ExiftoolPathValidate(toolPath string) (myPath string, err error)

ExiftoolPathValidate validates the provided path to exiftool exists, and if so, returns the absolute path to it.

func FillAspect ¶

func FillAspect(img *image.Image, aspect *model.Aspect) *image.Image

func FixOrientation ¶

func FixOrientation(img *image.Image, orientation int) error

FixOrientation modifies image in-place to match exif orientation data http://sylvana.net/jpegcrop/exif_orientation.html

func GetAspectLab ¶

func GetAspectLab(i model.Image, aspect *model.Aspect) ([]*model.Lab, error)

func GetImageCoverPartial ¶

func GetImageCoverPartial(i model.Image, coverPartial *model.CoverPartial) (*image.Image, error)

func GetImgAspectLab ¶

func GetImgCoverPartial ¶

func GetImgCoverPartial(img *image.Image, coverPartial *model.CoverPartial) *image.Image

func GetImgPartialLab ¶

func GetImgPartialLab(img *image.Image, coverPartial *model.CoverPartial) []*model.Lab

func GetOrientation ¶

func GetOrientation(path string) (int, error)

func GetPartialLab ¶

func OpenImage ¶

func OpenImage(path string) (*image.Image, error)

func OpenImg ¶

func OpenImg(i model.Image) (*image.Image, error)

func Round ¶

func Round(f float64) int

func SliceContainsInt64 ¶
