Overview ¶
Transform a "before layout" box tree into an "after layout" tree, by breaking boxes across lines and pages; and determining the position and dimension of each box fragment.
Boxes in the new tree have `used values` in their PositionX, PositionY, Width and Height attributes, amongst others. (see https://www.w3.org/TR/CSS21/cascade.html#used-value)
The laid out pages are ready to be printed or display on screen, which is done by the higher level `document` package.

Functions ¶
func DefaultImageSizing ¶ added in v0.0.10
func DefaultImageSizing(intrinsicWidth, intrinsicHeight, intrinsicRatio, specifiedWidth, specifiedHeight pr.MaybeFloat, defaultWidth, defaultHeight pr.Float, ) (concreteWidth, concreteHeight pr.Float)
Default sizing algorithm for the concrete object size. https://drafts.csswg.org/csswg/css-images-3/#default-sizing
func Layout ¶
func Layout(html *tree.HTML, stylesheets []tree.CSS, presentationalHints bool, fontConfig text.FontConfiguration) []*bo.PageBox
Layout lay out the whole document, returning one box per pages.
This includes line breaks, page breaks, absolute size and position for all boxes.
func LayoutReplacedBox ¶
func LayoutReplacedBox(box_ bo.ReplacedBoxITF) (drawWidth, drawHeight, positionX, positionY pr.Float)
LayoutReplacedBox computes the dimension of the content of a replaced box.
Types ¶
type AbsolutePlaceholder ¶
type AbsolutePlaceholder struct {
AliasBox
// contains filtered or unexported fields
}
AbsolutePlaceholder is left where an absolutely-positioned box was taken out of the flow.
