type LeadImageFinder ¶

type LeadImageFinder struct {
	// contains filtered or unexported fields
}

LeadImageFinder is used to identify a lead image for an article (sometimes known as a mast). Each candidate image is scored based on several heuristics including: - If an ancestor node of the image is the "figure" tag. - If the image is close with content.

In original dom-distiller they have two more heuristics which cannot be implemented here because it would require us to compute the stylesheet (NEED-COMPUTE-CSS): - The ratio of width/height. - The area of the image (width * height) relative to its container.
