constant Cairo.SURFACE_TYPE_QUARTZ
constant Cairo.SURFACE_TYPE_WIN32
constant Cairo.SURFACE_TYPE_BEOS
constant Cairo.SURFACE_TYPE_DIRECTFB
constant Cairo.SURFACE_TYPE_SVG

Description

The surface type is used to describe the type of a given surface. The surface types are also known as "backends" or "surface backends" within cairo.

For each type of a surface there is a corresponding class that generally will be of the form Cairo.*Surface. Examples are Cairo.ImageSurface and Cairo.PDFSurface.

The surface type can be queried with get_type

The various cairo_surface functions can be used with surfaces of any type, but some backends also provide type-specific functions that must only be called with a surface of the appropriate type.

Description

Cairo.Context is the main object used when drawing with cairo. To draw with cairo, you create a Cairo.Context, set the target surface, and drawing options for the Cairo.Context, create shapes with functions like move_to and line_to, and then draw shapes with stroke or fill.

Cairo.Context's can be pushed to a stack via save. They may then safely be changed, without loosing the current state. Use restore to restore to the saved state.
Method create

void Cairo.Context()->create(object(Cairo.Surface) surface)

Description

Create a Cairo.Context to a Cairo.Surface. See below for a trivial example that draws a triangle to a image surface and saves the result to a png-file with alpha-channel.

Example
// Draw a triangle to a png-file
  Cairo.Surface surface = Cairo.ImageSurface(Cairo.FORMAT_ARGB32, 100, 100);
  Cairo.Context cr = Cairo.Context(surface);
  cr->move_to(0,0);
  cr->line_to(100,100);
  cr->line_to(0,100);
  cr->close_path();
  cr->set_source(0.4, 0.5, 0.6, 1.0);
  cr->fill_preserve();
  cr->set_source(1.0, 1.0, 1.0, 1.0);
  cr->set_line_width(1.0);
  cr->stroke();
  mapping(string:Image.Image) image = surface->get_image();
  Image.Image im = image["image"];
  Image.Image alpha = image["alpha"];
  Stdio.write_file("output.png",
                   Image.PNG.encode(im, ([ "alpha" : alpha ])));
Method move_to

object(Cairo.Context) Cairo.Context()->move_to(int|float x, int|float y)

Description

If the current subpath is not empty, begin a new subpath. After this call the current point will be (x, y).

Parameter x

The X coordinate of the new position

Parameter y

The Y coordinate of the new position
Method rel_move_to

object(Cairo.Context) Cairo.Context()->rel_move_to(int|float x, int|float y)

Description

If the current subpath is not empty, begin a new subpath. After this call the current point will be offset by (x, y).

Parameter x

The X offset

Parameter y

The Y offset
Method arc

object(Cairo.Context) Cairo.Context()->arc(int|float xc, int|float yc, int|float radius, int|float angle1, int|float angle2)

Description

Adds a circular arc of the given radius to the current path. The arc is centered at (xc, yc), begins at angle1 and proceeds in the direction of increasing angles to end at angle2. If angle2 is less than angle1 it will be progressively increased by 2*PI until it is greater than angle1.

If there is a current point, an initial line segment will be added to the path to connect the current point to the beginning of the arc.

Angles are measured in radians. An angle of 0 is in the direction of the positive X axis (in user-space). An angle of PI radians (90 degrees) is in the direction of the positive Y axis (in user-space). Angles increase in the direction from the positive X axis toward the positive Y axis. So with the default transformation matrix, angles increase in a clockwise direction.

(To convert from degrees to radians, use degrees * (Math.pi / 180).)

This function gives the arc in the direction of increasing angles; see arc_negative to get the arc in the direction of decreasing angles.

The arc is circular in user-space. To achieve an elliptical arc, you can scale the current transformation matrix by different amounts in the X and Y directions. For example, to draw an ellipse in the box given by x, y, width, height:

Example
cr = Cairo.Context();
 cr->save();
 cr->translate(x + width / 2.0, y + height / 2.0);
 cr->scale(1.0 / (height / 2.0), 1.0 / (width / 2.0));
 cr->arc(0., 0.0, 1.0, 0.0, 2 * Math.pi);
 cr->restore();
Method arc_negative

object(Cairo.Context) Cairo.Context()->arc_negative(int|float xc, int|float yc, int|float radius, int|float angle1, int|float angle2)

Description

Adds a circular arc of the given radius to the current path. The arc is centered at (xc, yc), begins at angle1 and proceeds in the direction of decreasing angles to end at angle2. If angle2 is greater than angle1 it will be progressively decreased by [2*PI] until it is greater than angle1.

See arc for more details. This function differs only in the direction of the arc between the two angles.
Method rel_line_to

object(Cairo.Context) Cairo.Context()->rel_line_to(int|float dx, int|float dy)

Method line_to

object(Cairo.Context) Cairo.Context()->line_to(int|float x, int|float y)

Method cairo_curve_to

object(Cairo.Context) Cairo.Context()->cairo_curve_to(float x1, float y1, float x2, float y2, float x3, float y3)

Parameter x1

Parameter y1

the Y coordinate of the first control point

Parameter x2

the X coordinate of the second control point

Parameter y2

the Y coordinate of the second control point

Parameter x3

the X coordinate of the end of the curve

Parameter y3

the Y coordinate of the end of the curve

Adds a cubic Bezier spline to the path from the current point to position (x3, y3) in user-space coordinates, using (x1, y1) and (x2, y2) as the control points. After this call the current point will be (x3, y3).
Method cairo_rel_curve_to

object(Cairo.Context) Cairo.Context()->cairo_rel_curve_to(float dx1, float dy1, float dx2, float dy2, float dx3, float dy3)

Method close_path

object(Cairo.Context) Cairo.Context()->close_path()

object(Cairo.Context) Cairo.Context()->set_source(float r, float g, float b)
object(Cairo.Context) Cairo.Context()->set_source(float r, float g, float b, float a)

Method fill_preserve

Method fill

object(Cairo.Context) Cairo.Context()->fill()

Method clip

void Cairo.Context()->clip()

Method clip_preserve

Method reset_clip

object(Cairo.Context) Cairo.Context()->reset_clip()

Method save

object(Cairo.Context) Cairo.Context()->save()

Method restore

void Cairo.Context()->restore()

Note

This function does not return its own object. This is because the state is cleared from the cairo context when restore is called, and nesting of this command makes little sense.
Method translate

object(Cairo.Context) Cairo.Context()->translate(float|int tx, float|int ty)

Method scale

object(Cairo.Context) Cairo.Context()->scale(float|int sx, float|int sy)

Method rotate

object(Cairo.Context) Cairo.Context()->rotate(float|int r)

Method paint

object(Cairo.Context) Cairo.Context()->paint()

Method paint_with_alpha

object(Cairo.Context) Cairo.Context()->paint_with_alpha()

Method new_path

object(Cairo.Context) Cairo.Context()->new_path()

Method rectangle

object(Cairo.Context) Cairo.Context()->rectangle()

Method set_line_width

object(Cairo.Context) Cairo.Context()->set_line_width(float width)

Method stroke

void Cairo.Context()->stroke()

Note

This function does not return its own object. This is because the path is cleared from the cairo context when stroke is called, and nesting of this command makes little sense.
Method copy_path

object(Cairo.Path) Cairo.Context()->copy_path()

Method copy_path_flat

object(Cairo.Path) Cairo.Context()->copy_path_flat()

Method append_path

object(Cairo.Context) Cairo.Context()->append_path(Cairo.Path)

Method transform

object(Cairo.Context) Cairo.Context()->transform(object(Cairo.Matrix) matrix)

Method identity_matrix

object(Cairo.Context) Cairo.Context()->identity_matrix()

Description

Reset the transformation matrix on this context to the identity matrix.
Method select_font_face

object(Cairo.Context) Cairo.Context()->select_font_face(string font_family, int slant, int weight)

Description

Select font.

Selects a family and style of font from a simplified description as a family name, slant and weight. This function is meant to be used only for applications with simple font needs: Cairo doesn't provide for operations such as listing all available fonts on the system, and it is expected that most applications will need to use a more comprehensive font handling and text layout library in addition to cairo.
Method set_font_size

object(Cairo.Context) Cairo.Context()->set_font_size(float|int size)

Description

Sets the current font matrix to a scale by a factor of size, replacing any font matrix previously set with cairo_set_font_size() or cairo_set_font_matrix(). This results in a font size of size user space units. (More precisely, this matrix will result in the font's em-square being a size by size square in user space.)
Method set_font_matrix

object(Cairo.Context) Cairo.Context()->set_font_matrix(Cairo.Matrix)

Method get_font_matrix

object(Cairo.Matrix) Cairo.Context()->get_font_matrix()

Method set_font_options

object(Cairo.Context) Cairo.Context()->set_font_options(object(Cairo.FontOptions) options)

Method get_font_options

object(Cairo.FontOptions) Cairo.Context()->get_font_options()

Method show_text

object(Cairo.Context) Cairo.Context()->show_text(string text)

Description

A drawing operator that generates the shape from a string of UTF-8 characters, rendered according to the current font_face, font_size (font_matrix), and font_options.

This function first computes a set of glyphs for the string of text. The first glyph is placed so that its origin is at the current point. The origin of each subsequent glyph is offset from that of the previous glyph by the advance values of the previous glyph.

After this call the current point is moved to the origin of where the next glyph would be placed in this same progression. That is, the current point will be at the origin of the final glyph offset by its advance values. This allows for easy display of a single logical string with multiple calls to cairo_show_text().

NOTE: The cairo_show_text() function call is part of what the cairo designers call the "toy" text API. It is convenient for short demos and simple programs, but it is not expected to be adequate for the most serious of text-using applications. See cairo_show_glyphs() for the "real" text display API in cairo.
Method set_operator
