}The CairoContext classEinführungContext is the main object used when drawing with cairo. To draw with cairo, you create a CairoContext, set the target CairoSurface, and drawing options for the CairoContext, create shapes with functions . like CairoContext::moveTo and CairoContext::lineTo, and then draw shapes with CairoContext::stroke or CairoContext::fill. Contexts can be pushed to a stack via CairoContext::save. They may then safely be changed, without loosing the current state. Use CairoContext::restore to restore to the saved state.

}The CairoStatus classEinführungCairoStatus is used to indicate errors that can occur when using Cairo. In some cases it is returned directly by functions. but when using CairoContext, the last error, if any, is stored in the object and can be retrieved with CairoContext::status or cairo_status. New entries may be added in future versions. Use Cairo::statusToString or cairo_status_to_string to get a human-readable representation of an error message. KlassenbeschreibungCairoStatus

}The CairoFontOptions classEinführungAn opaque structure holding all options that are used when rendering fonts.

New features may be added to CairoFontOptions in the future. For this reason CairoFontOptions::copy, CairoFontOptions::equal, CairoFontOptions::merge, CairoFontOptions::hash (cairo_font_options_copy(), cairo_font_options_equal(), cairo_font_options_merge(), and cairo_font_options_hash() in procedural way) should be used to copy, check for equality, merge, or compute a hash value of CairoFontOptions objects.

The CairoFontType classEinführungCairoFontType class is an abstract final class that contains constants used to describe the type of a given CairoFontFace or CairoScaledFont. The font types are also known as "font backends" within cairo. The type of a CairoFontFace is determined by the how it is created, an example would be the CairoToyFontFace::__construct. The CairoFontFace type can be queried with CairoFontFace::getType or cairo_font_face_get_type The various CairoFontFace functions can be used with a font face of any type. The type of a CairoScaledFont is determined by the type of the CairoFontFace passed to CairoScaledFont::__construct or cairo_scaled_font_create. The scaled font type can be queried with CairoScaledFont::getType or cairo_scaled_font_get_type. KlassenbeschreibungCairoFontType

The CairoContent classEinführungCairoContent is used to describe the content that a surface will contain, whether color information, alpha information (translucence vs. opacity), or both.

The CairoFillRule classEinführungA CairoFillRule is used to select how paths are filled. For both fill rules, whether or not a point is included in the fill is determined by taking a ray from that point to infinity and looking at intersections with the path. The ray can be in any direction, as long as it doesn't pass through the end point of a segment or have a tricky intersection such as intersecting tangent to the path. (Note that filling is not actually implemented in this way. This is just a description of the rule that is applied.)

The CairoHintMetrics classEinführungSpecifies whether to hint font metrics; hinting font metrics means quantizing them so that they are integer values in device space.

The CairoHintStyle classEinführungSpecifies the type of hinting to do on font outlines. Hinting is the process of fitting outlines to the pixel grid in order to improve the appearance of the result.

)The CairoOperator classEinführungThis is used to set the compositing operator for all cairo drawing operations.
The default operator is The operators marked as unbounded modify their destination even outside of the mask layer (that is, their effect is not bound by the mask layer). However, their effect can still be limited by way of clipping. To keep things simple, the operator descriptions here document the behavior for when both source and destination are either fully transparent or fully opaque. The actual implementation works for translucent layers too. For a more detailed explanation of the effects of each operator, including the mathematical definitions, see http://cairographics.org/operators/. KlassenbeschreibungCairoOperator
