func Asset(name string) ([]byte, error)
Asset loads and returns the asset for the given name. It returns an error if the asset could not be found or could not be loaded.
func AssetDir(name string) ([]string, error)
AssetDir returns the file names below a certain directory embedded in the file by go-bindata. For example if you run go-bindata on data/... and data contains the following hierarchy:
data/
foo.txt
img/
a.png
b.png
then AssetDir("data") would return []string{"foo.txt", "img"} AssetDir("data/img") would return []string{"a.png", "b.png"} AssetDir("foo.txt") and AssetDir("notexist") would return an error AssetDir("") will return []string{"data"}.
func AssetInfo(name string) (os.FileInfo, error)
AssetInfo loads and returns the asset info for the given name. It returns an error if the asset could not be found or could not be loaded.
func AssetNames() []string
AssetNames returns the names of the assets.
func MustAsset(name string) []byte
MustAsset is like Asset but panics when Asset would return an error. It simplifies safe initialization of global variables.
func NewCmykIsoCoatedV2OutputIntent(subtype model.PdfOutputIntentType) (*model.PdfOutputIntent, error)
NewCmykIsoCoatedV2OutputIntent creates a new standard OutputIntent for the 4 component CMYK color spaces based on the ISO Coated v2 300 bas ICC profile.
func NewISOCoatedV2Gray1CBasOutputIntent(subtype model.PdfOutputIntentType) (*model.PdfOutputIntent, error)
NewISOCoatedV2Gray1CBasOutputIntent creates a new OutputIntent that contains ISO Coated Grey v2 FOGRA 39L
func NewSRGBv2OutputIntent(subtype model.PdfOutputIntentType) (*model.PdfOutputIntent, error)
NewSRGBv2OutputIntent creates a new OutputIntent that contains standard ICC sRGB v2 profile.
func NewSRGBv4OutputIntent(subtype model.PdfOutputIntentType) (*model.PdfOutputIntent, error)
NewSRGBv4OutputIntent creates a new OutputIntent that contains standard ICC sRGB v4 profile.
func RestoreAsset(dir, name string) error
RestoreAsset restores an asset under the given directory
func RestoreAssets(dir, name string) error
RestoreAssets restores an asset under the given directory recursively
