Classes
class	wxGraphicsPath
	A wxGraphicsPath is a native representation of a geometric path. More...

class	wxGraphicsObject
	This class is the superclass of native graphics objects like pens etc. More...

class	wxGraphicsBitmap
	Represents a bitmap. More...

class	wxGraphicsContext
	A wxGraphicsContext instance is the object that is drawn upon. More...

class	wxGraphicsGradientStop
	Represents a single gradient stop in a collection of gradient stops as represented by wxGraphicsGradientStops. More...

class	wxGraphicsGradientStops
	Represents a collection of wxGraphicGradientStop values for use with CreateLinearGradientBrush and CreateRadialGradientBrush. More...

class	wxGraphicsPenInfo
	This class is a helper used for wxGraphicsPen creation using named parameter idiom: it allows specifying various wxGraphicsPen attributes using the chained calls to its clearly named methods instead of passing them in the fixed order to wxGraphicsPen constructors. More...

Enumeration Type Documentation

◆ wxAntialiasMode

enum wxAntialiasMode

Anti-aliasing modes used by wxGraphicsContext::SetAntialiasMode().

Enumerator
wxANTIALIAS_NONE	No anti-aliasing.
wxANTIALIAS_DEFAULT	The default anti-aliasing.

◆ wxCompositionMode

enum wxCompositionMode

Compositing is done using Porter-Duff compositions (see http://keithp.com/~keithp/porterduff/p253-porter.pdf) with wxGraphicsContext::SetCompositionMode().

The description give a short equation on how the values of a resulting pixel are calculated. R = Result, S = Source, D = Destination, colors premultiplied with alpha Ra, Sa, Da their alpha components

Enumerator
wxCOMPOSITION_INVALID	Indicates invalid or unsupported composition mode. This value can't be passed to wxGraphicsContext::SetCompositionMode(). Since 2.9.2
wxCOMPOSITION_CLEAR	R = 0
wxCOMPOSITION_SOURCE	R = S
wxCOMPOSITION_OVER	R = S + D*(1 - Sa)
wxCOMPOSITION_IN	R = SDa*
wxCOMPOSITION_OUT	R = S*(1 - Da)
wxCOMPOSITION_ATOP	R = SDa +* D*(1 - Sa)
wxCOMPOSITION_DEST	R = D, essentially a noop
wxCOMPOSITION_DEST_OVER	R = S*(1 - Da) + D
wxCOMPOSITION_DEST_IN	R = DSa*
wxCOMPOSITION_DEST_OUT	R = D*(1 - Sa)
wxCOMPOSITION_DEST_ATOP	R = S(1 - Da) + DSa
wxCOMPOSITION_XOR	R = S(1 - Da) + D(1 - Sa)
wxCOMPOSITION_ADD	R = S + D
wxCOMPOSITION_DIFF	Result is the absolute value of the difference between the source and the destination. This composition mode is only supported by Cairo and CoreGraphics-based implementations, i.e. in wxGTK and wxOSX only (unless Cairo-based renderer is explicitly under the other platforms). When the source colour is white, this mode can be used to emulate wxINVERT logical function of wxDC, i.e. drawing using this mode twice restores the original contents. Since 3.2.0

◆ wxGradientType

enum wxGradientType

Used to indicate what kind of gradient is set in a wxGraphicsPenInfo object.

Since: 3.1.3

Enumerator
wxGRADIENT_NONE
wxGRADIENT_LINEAR
wxGRADIENT_RADIAL

◆ wxInterpolationQuality

enum wxInterpolationQuality

Interpolation quality used by wxGraphicsContext::SetInterpolationQuality().

Enumerator
wxINTERPOLATION_DEFAULT	default interpolation, based on type of context, in general medium quality
wxINTERPOLATION_NONE	no interpolation
wxINTERPOLATION_FAST	fast interpolation, suited for interactivity
wxINTERPOLATION_GOOD	better quality
wxINTERPOLATION_BEST	best quality, not suited for interactivity
