Detailed Description

This class contains rendering configuration values.

A reference to an object of this class replaces what used to be part of the parameter list of various draw()/render() methods. With that old approach, each new rendering configuration option required changes in many signatures and function calls. In addition, the boolean options were not verbose at all.

Objects are meant to be initialized by initializer lists (C++11).

Member Enumeration Documentation

◆ Option

enum OpenOrienteering::RenderConfig::Option

Flags indicating particular rendering configuration options.

Enumerator
Screen	Indicates that the drawing is for the screen. Can turn on optimizations which result in slightly lower display quality (e.g. disable antialiasing for texts) for the benefit of speed.
DisableAntialiasing	Forces disabling of Antialiasing.
ForceMinSize	Forces a minimum size of app. 1 pixel for objects. Makes maps look better at small zoom levels without antialiasing.
HelperSymbols	Activates display of symbols with the "helper symbol" flag.
Highlighted	Makes the color appear highlighted.
RequireSpotColor	Skips colors which do not have a spot color definition.
Tool	The recommended flags for tools.
NoOptions	No option activated.

Member Function Documentation

◆ testFlag()

bool OpenOrienteering::RenderConfig::testFlag ( const Option flag ) const

inline

A convenience method for testing flags in the options value.

Member Data Documentation

◆ bounding_box

QRectF OpenOrienteering::RenderConfig::bounding_box

The bounding box of the area to be drawn.

Given in map coordinates.

◆ map

const Map& OpenOrienteering::RenderConfig::map

The map.

◆ opacity

qreal OpenOrienteering::RenderConfig::opacity

The opacity.

◆ options

Options OpenOrienteering::RenderConfig::options

The rendering options.

◆ scaling

qreal OpenOrienteering::RenderConfig::scaling

The scaling expressed as pixels per mm.

Used to calculate the final object sizes when ForceMinSize is set.
