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 | wxGraphicsRenderer |
| A wxGraphicsRenderer is the instance corresponding to the rendering engine used. More... | |
| class | wxGraphicsBrush |
| A wxGraphicsBrush is a native representation of a brush. More... | |
| class | wxGraphicsFont |
| A wxGraphicsFont is a native representation of a font. 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... | |
| class | wxGraphicsPen |
| A wxGraphicsPen is a native representation of a pen. More... | |
| class | wxGraphicsMatrix |
| A wxGraphicsMatrix is a native representation of an affine matrix. More... | |
Variables | |
| const wxGraphicsPen | wxNullGraphicsPen |
| const wxGraphicsBrush | wxNullGraphicsBrush |
| const wxGraphicsFont | wxNullGraphicsFont |
| const wxGraphicsBitmap | wxNullGraphicsBitmap |
| const wxGraphicsMatrix | wxNullGraphicsMatrix |
| const wxGraphicsPath | wxNullGraphicsPath |
| enum wxAntialiasMode |
Anti-aliasing modes used by wxGraphicsContext::SetAntialiasMode().
| Enumerator | |
|---|---|
| wxANTIALIAS_NONE | No anti-aliasing. |
| wxANTIALIAS_DEFAULT | The default anti-aliasing. |
| 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().
|
| wxCOMPOSITION_CLEAR | R = 0 |
| wxCOMPOSITION_SOURCE | R = S |
| wxCOMPOSITION_OVER | R = S + D*(1 - Sa) |
| wxCOMPOSITION_IN | R = S*Da |
| wxCOMPOSITION_OUT | R = S*(1 - Da) |
| wxCOMPOSITION_ATOP | R = S*Da + D*(1 - Sa) |
| wxCOMPOSITION_DEST | R = D, essentially a noop |
| wxCOMPOSITION_DEST_OVER | R = S*(1 - Da) + D |
| wxCOMPOSITION_DEST_IN | R = D*Sa |
| wxCOMPOSITION_DEST_OUT | R = D*(1 - Sa) |
| wxCOMPOSITION_DEST_ATOP | R = S*(1 - Da) + D*Sa |
| wxCOMPOSITION_XOR | R = S*(1 - Da) + D*(1 - Sa) |
| wxCOMPOSITION_ADD | R = S + D |
| enum wxGradientType |
Used to indicate what kind of gradient is set in a wxGraphicsPenInfo object.
| Enumerator | |
|---|---|
| wxGRADIENT_NONE | |
| wxGRADIENT_LINEAR | |
| wxGRADIENT_RADIAL | |
Interpolation quality used by wxGraphicsContext::SetInterpolationQuality().
