Detailed Description

Interface class for graphics context objects, used internally by the Graphics class.

Users are not supposed to create instances of this class directly - do your drawing via the Graphics object instead.

It's a base class for different types of graphics context, that may perform software-based or OS-accelerated rendering.

E.g. the LowLevelGraphicsSoftwareRenderer renders onto an image in memory, but other subclasses could render directly to a windows HDC, a Quartz context, or an OpenGL context.

◆ isVectorDevice()

virtual bool juce::LowLevelGraphicsContext::isVectorDevice ( ) const

◆ setOrigin()

virtual void juce::LowLevelGraphicsContext::setOrigin ( Point< int )
pure virtual

Moves the origin to a new position.

The coordinates are relative to the current origin, and indicate the new position of (0, 0).

Implemented in juce::RenderingHelpers::StackBasedLowLevelGraphicsContext< SavedStateType >, juce::RenderingHelpers::StackBasedLowLevelGraphicsContext< RenderingHelpers::SoftwareRendererSavedState >, and juce::LowLevelGraphicsPostScriptRenderer.
