Enumeration Type Documentation

enum wxFloodFillStyle

Flood styles used by wxDC::FloodFill.

Enumerator:

wxFLOOD_SURFACE	The flooding occurs until a colour other than the given colour is encountered.
wxFLOOD_BORDER	The area to be flooded is bounded by the given colour.

enum wxMappingMode

The mapping used to transform logical units to device units.

See wxDC::SetMapMode.

Enumerator:

wxMM_TEXT	Each logical unit is 1 device pixel. This is the default mapping mode for all wxDC-derived classes.
wxMM_METRIC	Each logical unit is 1 millimeter.
wxMM_LOMETRIC	Each logical unit is 1/10 of a millimeter.
wxMM_TWIPS	Each logical unit is 1/20 of a "printer point", or 1/1440 of an inch (also known as "twip"). Equivalent to about 17.64 micrometers.
wxMM_POINTS	Each logical unit is a "printer point" i.e. 1/72 of an inch. Equivalent to about 353 micrometers.

enum wxRasterOperationMode

Logical raster operations which can be used with wxDC::SetLogicalFunction and some other wxDC functions (e.g.

wxDC::Blit and wxDC::StretchBlit).

The description of the values below refer to how a generic src source pixel and the corresponding dst destination pixel gets combined together to produce the final pixel. E.g. wxCLEAR and wxSET completely ignore the source and the destination pixel and always put zeroes or ones in the final surface.

Enumerator:

wxCLEAR	0
wxXOR	src XOR dst
wxINVERT	NOT dst.
wxOR_REVERSE	src OR (NOT dst)
wxAND_REVERSE	src AND (NOT dst)
wxCOPY	src
wxAND	src AND dst
wxAND_INVERT	(NOT src) AND dst
wxNO_OP	dst
wxNOR	(NOT src) AND (NOT dst)
wxEQUIV	(NOT src) XOR dst
wxSRC_INVERT	(NOT src)
wxOR_INVERT	(NOT src) OR dst
wxNAND	(NOT src) OR (NOT dst)
wxOR	src OR dst
wxSET	1
