Types ¶
type Document ¶
type Document struct {
// A list of `Page` objects.
Pages []Page
// A `DocumentMetadata` object.
// Contains information that does not belong to a specific page
// but to the whole document.
Metadata utils.DocumentMetadata
// contains filtered or unexported fields
}
Document is a rendered document ready to be painted on a drawing target.
It is obtained by calling the `Render()` function.
func Render ¶
func Render(html *tree.HTML, stylesheets []tree.CSS, presentationalHints bool, fontConfig *text.FontConfiguration) Document
Render performs the layout of the whole document and returns a document ready to be painted.
fontConfig is mandatory presentationalHints should default to `false`
func (*Document) Write ¶
Write paints the pages in the given `target`, with meta-data.
The zoom factor is in PDF units per CSS units, and should default to 1. Warning : all CSS units are affected, including physical units like `cm` and named sizes like `A4`. For values other than 1, the physical CSS units will thus be "wrong".
`attachments` is an optional list of additional file attachments for the generated PDF document, added to those collected from the metadata.
type Link ¶
type Link struct {
// Type is one of three strings :
// - "external": `target` is an absolute URL
// - "internal": `target` is an anchor name
// The anchor might be defined in another page,
// in multiple pages (in which case the first occurence is used),
// or not at all.
// - "attachment": `target` is an absolute URL and points
// to a resource to attach to the document.
Type string
Target string
// [x_min, y_min, x_max, y_max] in CSS
// pixels from the top-left of the page.
Rectangle [4]fl
}
Link is a positionned link in a page.
type Page ¶
type Page struct {
// The page bleed widths with values in CSS pixels.
Bleed Bleed
// The page width, including margins, in CSS pixels.

// contains filtered or unexported fields
}
Page represents a single rendered page.

If false, content can overflow. (leftX=0, topY=0, scale=1, clip=false)
