A PdfSurface provides a way to render PDF documents from cairo.
This surface is not rendered to the screen but instead renders the drawing to a PDF file on disk.
Cairo::PdfSurface::PdfSurface | ( | cairo_surface_t * | cobject, |
bool | has_reference = false |
||
) | [explicit] |
Create a C++ wrapper for the C instance.
This C++ instance should then be given to a RefPtr.
cobject | The C instance. |
has_reference | whether we already have a reference. Otherwise, the constructor will take an extra reference. |
virtual Cairo::PdfSurface::~PdfSurface | ( | ) | [virtual] |
static RefPtr<PdfSurface> Cairo::PdfSurface::create | ( | std::string | filename, |
double | width_in_points, | ||
double | height_in_points | ||
) | [static] |
Creates a PdfSurface with a specified dimensions that will be saved as the given filename.
filename | The name of the PDF file to save the surface to |
width_in_points | The width of the PDF document in points |
height_in_points | The height of the PDF document in points |
static RefPtr<PdfSurface> Cairo::PdfSurface::create | ( | cairo_write_func_t | write_func, |

static RefPtr<PdfSurface> Cairo::PdfSurface::create_for_stream | ( | const SlotWriteFunc & | write_func, |
double | width_in_points, | ||
double | height_in_points | ||
) | [static] |
Creates a PdfSurface with a specified dimensions that will be written to the given write function instead of saved directly to disk.
write_func | The function to be called when the backend needs to write data to an output stream |
width_in_points | The width of the PDF document in points |
height_in_points | The height of the PDF document in points |
static const std::vector<PdfVersion> Cairo::PdfSurface::get_versions | ( | ) | [static] |
void Cairo::PdfSurface::restrict_to_version | ( | PdfVersion | version | ) |
Restricts the generated PDF file to version.
See get_versions() for a list of available version values that can be used here.
This function should only be called before any drawing operations have been performed on the given surface. The simplest way to do this is to call this function immediately after creating the surface.
void Cairo::PdfSurface::set_size | ( | double | width_in_points, |
double | height_in_points | ||
) |
Changes the size of a PDF surface for the current (and subsequent) pages.
This function should only be called before any drawing operations have been performed on the current page. The simplest way to do this is to call this function immediately after creating the surface or immediately after completing a page with either Context::show_page() or Context::copy_page().
width_in_points | new surface width, in points (1 point == 1/72.0 inch) |
height_in_points | new surface height, in points (1 point == 1/72.0 inch) |
static std::string Cairo::PdfSurface::version_to_string | ( | PdfVersion | version | ) | [static] |
Get the string representation of the given version id.
This function will return an empty string if version isn't valid. See get_versions() for a way to get the list of valid version ids.
