Overview

Package pdf implements the PDF backend for libcairo rendering.

Libcairo must be compiled with

CAIRO_HAS_PDF_SURFACE

in addition to the requirements of cairo.

Index

• Constants
• func Versions() (versions []version)
• type Surface
  • func New(w io.Writer, width, height float64) (Surface, error)
  • func (s Surface) RestrictTo(v version) error
  • func (s Surface) SetSize(width, height float64) error

Constants

const (
	//Version1_4 is the version 1.4 of the PDF specification.
	Version1_4 version = C.CAIRO_PDF_VERSION_1_4
	//Version1_5 is the version 1.5 of the PDF specification.
	Version1_5 version = C.CAIRO_PDF_VERSION_1_5
)

The version type describes the version number of the PDF specification that a generated PDF file will conform to.

Originally cairo_pdf_version_t.

Functions

func Versions

func Versions() (versions []version)

Versions reports the supported PDF versions.

Originally cairo_pdf_get_versions.

Types

type Surface

type Surface struct {
	cairo.XtensionPagedVectorSurface
}

Surface is a PDF surface.

Surface implements cairo.PagedVectorSurface.

func New

func New(w io.Writer, width, height float64) (Surface, error)

New creates a new PDF of the specified size. W is the Writer the PDF is written to. Width and height are in the unit of a typographical point (1 point = 1/72 inch).

Originally cairo_pdf_surface_create_for_stream.

func (Surface) RestrictTo

func (s Surface) RestrictTo(v version) error

RestrictTo restricts the generated PDF to the specified verison.

This method should only be called before any drawing operations have been performed on this surface.

Originally cairo_pdf_surface_restrict_to_version.

func (Surface) SetSize

func (s Surface) SetSize(width, height float64) error

SetSize changes the size of the PDF surface for the current and subsequent pages.

This method should only be called before any drawing operations have been performed on the current page.

Originally cairo_pdf_surface_set_size.
