Types ¶
type ImageAreaScorer ¶
type ImageAreaScorer struct {
// contains filtered or unexported fields
}
ImageAreaScorer uses image area (length*width) as its heuristic. Unfortunately to do that we need to compute CSS which is impossible in Go, so this scorer do nothing. NEED-COMPUTE-CSS.
func NewImageAreaScorer ¶
func NewImageAreaScorer(maxScore, minArea, maxArea int) *ImageAreaScorer
NewImageAreaScorer returns and initiates the ImageAreaScorer.
func (*ImageAreaScorer) GetImageScore ¶
func (s *ImageAreaScorer) GetImageScore(_ *html.Node) int
func (*ImageAreaScorer) GetMaxScore ¶
func (s *ImageAreaScorer) GetMaxScore() int
type ImageDomDistanceScorer ¶
type ImageDomDistanceScorer struct {
// contains filtered or unexported fields
}
ImageDomDistanceScorer uses DOM distance as its heuristic.
func NewImageDomDistanceScorer ¶
func NewImageDomDistanceScorer(maxScore int, firstContent *html.Node) *ImageDomDistanceScorer
NewImageDomDistanceScorer returns and initiates the ImageDomDistanceScorer.
func (*ImageDomDistanceScorer) GetImageScore ¶
func (s *ImageDomDistanceScorer) GetImageScore(node *html.Node) int
func (*ImageDomDistanceScorer) GetMaxScore ¶
func (s *ImageDomDistanceScorer) GetMaxScore() int
type ImageHasFigureScorer ¶
type ImageHasFigureScorer struct {
// contains filtered or unexported fields
}
ImageHasFigureScorer scores based on if the image has a "figure" node as an ancestor.
func NewImageHasFigureScorer ¶
func NewImageHasFigureScorer(maxScore int) *ImageHasFigureScorer
NewImageHasFigureScorer returns and initiates the ImageHasFigureScorer.
func (*ImageHasFigureScorer) GetImageScore ¶
func (s *ImageHasFigureScorer) GetImageScore(node *html.Node) int
func (*ImageHasFigureScorer) GetMaxScore ¶
func (s *ImageHasFigureScorer) GetMaxScore() int
type ImageRatioScorer ¶
type ImageRatioScorer struct {
// contains filtered or unexported fields
}
ImageRatioScorer uses image ratio (length/width) as its heuristic. Unfortunately to do that we need to compute CSS which is impossible in Go, so this scorer do nothing. NEED-COMPUTE-CSS.
func NewImageRatioScorer ¶
func NewImageRatioScorer(maxScore int) *ImageRatioScorer
NewImageRatioScorer returns and initiates the ImageRatioScorer.
func (*ImageRatioScorer) GetImageScore ¶
func (s *ImageRatioScorer) GetImageScore(_ *html.Node) int
func (*ImageRatioScorer) GetMaxScore ¶
func (s *ImageRatioScorer) GetMaxScore() int
type ImageScorer ¶
type ImageScorer interface {
// GetImageScore returns a particular image a score based on the heuristic
// implemented in this ImageScorer and what the max score is set to.
GetImageScore(e *html.Node) int
// GetMaxScore returns the maximum possible score that this ImageScorer can return.
GetMaxScore() int
}
ImageScorer is used to represent a single heuristic used in image extraction. The provided image will be given a score based on the heuristic and a max score.
