Enumeration Type Documentation

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.

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.

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:
