type Common 

type Common struct {
	Incr identity.Incrementer

}

type IntegrityClient 

type IntegrityClient struct{}

func (*IntegrityClient) Fingerprint 

func (c *IntegrityClient) Fingerprint(res resources.Resource, algo string) (resources.Resource, error)

Fingerprint applies fingerprinting of the given resource and hash algorithm. It defaults to sha256 if none given, and the options are md5, sha256 or sha512. The same algo is used for both the fingerprinting part (aka cache busting) and the base64-encoded Subresource Integrity hash, so you will have to stay away from md5 if you plan to use both. See https://developer.mozilla.org/en-US/docs/Web/Security/Subresource_Integrity

type MinifierClient

}

func (*ResourceImage) Colors 

func (i *ResourceImage) Colors() ([]string, error)

Colors returns a slice of the most dominant colors in an images using a simple histogram method.

func (*ResourceImage) Crop 

func (i *ResourceImage) Crop(spec string) (resources.ImageResource, error)

Crop the images to the specified dimensions without resizing using the given anchor point. Space delimited config, e.g. `200x300 TopLeft`.

func (*ResourceImage) DecodeImage 

func (i *ResourceImage) DecodeImage() (image.Image, error)

DecodeImage decodes the images source into an Image. This for internal use only.

func (*ResourceImage) Exif 

func (i *ResourceImage) Exif() *exif.ExifInfo

func (*ResourceImage) Fill 

func (i *ResourceImage) Fill(spec string) (resources.ImageResource, error)

Fill scales the images to the smallest possible size that will cover the specified dimensions, crops the resized images to the specified dimensions using the given anchor point. Space delimited config, e.g. `200x300 TopLeft`.

func (*ResourceImage) Filter 

func (i *ResourceImage) Filter(filters ...any) (resources.ImageResource, error)

func (*ResourceImage) Fit 

func (i *ResourceImage) Fit(spec string) (resources.ImageResource, error)
