NAME<\/a> Cairo \u2212 Perl interface to the cairo 2d vector graphics library<\/p>\n use Cairo; Cairo provides Perl bindings for the vector graphics library cairo. It supports multiple output targets, including PNG, PDF<\/small> and SVG.<\/small> Cairo produces identical output on all those targets.<\/p>\n This is a listing of the API<\/small> Cairo provides. For more verbose information, refer to the cairo manual at Drawing<\/b> Cairo::Context<\/i> is the main object used when drawing with Cairo. To draw with Cairo, you create a Cairo::Context<\/i>, set the target surface, and drawing options for the Cairo::Context<\/i>, create shapes with methods like “$cr\u2212>move_to” and “$cr\u2212>line_to”, and then draw shapes with “$cr\u2212>stroke” or “$cr\u2212>fill”.<\/p>\n Cairo::Context<\/i>\u2019s can be pushed to a stack via “$cr\u2212>save”. They may then safely be changed, without loosing the current state. Use “$cr\u2212>restore” to restore to the saved state. $surface: Cairo::Surface<\/i><\/p>\n $cr\u2212>save $content: Cairo::Content<\/i><\/p>\n $pattern = $cr\u2212>pop_group [1.2] $red: double $cr\u2212>set_source_rgba ($red, $green, $blue, $alpha)<\/p>\n $red: double $cr\u2212>set_source ($source)<\/p>\n $source: Cairo::Pattern<\/i><\/p>\n $cr\u2212>set_source_surface ($surface, $x, $y)<\/p>\n $surface: Cairo::Surface<\/i> $source = $cr\u2212>get_source $antialias: Cairo::Antialias<\/i><\/p>\n $antialias = $cr\u2212>get_antialias $offset: double $cr\u2212>set_fill_rule ($fill_rule)<\/p>\n $fill_rule: Cairo::FillRule<\/i><\/p>\n $fill_rule = $cr\u2212>get_fill_rule $line_cap: Cairo::LineCap<\/i><\/p>\n $line_cap = $cr\u2212>get_line_cap $line_join: Cairo::LineJoin<\/i><\/p>\n $line_join = $cr\u2212>get_line_join $width: double<\/p>\n $width = $cr\u2212>get_line_width $limit: double<\/p>\n ($offset, @dashes) = $cr\u2212>get_dash [1.4] $op: Cairo::Operator<\/i><\/p>\n $op = $cr\u2212>get_operator $tolerance: double<\/p>\n $tolerance = $cr\u2212>get_tolerance $x: double @rectangles = $cr\u2212>copy_clip_rectangle_list [1.4] $x: double $cr\u2212>mask ($pattern)<\/p>\n $pattern: Cairo::Pattern<\/i><\/p>\n $cr\u2212>mask_surface ($surface, $surface_x, $surface_y)<\/p>\n $surface: Cairo::Surface<\/i> $cr\u2212>paint $alpha: double<\/p>\n $cr\u2212>stroke $x: double $cr\u2212>tag_begin($name, $atts) [1.16]<\/p>\n $name: string $cr\u2212>tag_end($name) [1.16]<\/p>\n $name: string<\/p>\n Predefined names:<\/p>\n Cairo::TAG_DEST [1.16] $cr\u2212>copy_page Paths — Creating paths and manipulating path data<\/i><\/p>\n $path = [ Cairo::Path<\/i> is a data structure for holding a path. This data structure serves as the return value for “$cr\u2212>copy_path” and “$cr\u2212>copy_path_flat” as well the input value for “$cr\u2212>append_path”.<\/p>\n Cairo::Path<\/i> is represented as an array reference that contains path elements, represented by hash references with two keys: type<\/i> and points<\/i>. The value for type<\/i> can be either of the following: The value for points<\/i> is an array reference which contains zero or more points. Points are represented as array references that contain two doubles: x<\/i> and y<\/i>. The necessary number of points depends on the type<\/i> of the path element: The semantics and ordering of the coordinate values are consistent with “$cr\u2212>move_to”, “$cr\u2212>line_to”, “$cr\u2212>curve_to”, and “$cr\u2212>close_path”.<\/p>\n Note that the paths returned by Cairo are implemented as tied array references which do not<\/b> support adding, removing or shuffling of path segments.
