\section{\class{wxMask}}\label{wxmask}

This class encapsulates a monochrome mask bitmap, where the masked area is black and
the unmasked area is white.

\wxheading{Derived from}

\helpref{wxObject}{wxobject}

\wxheading{Include files}

<wx/bitmap.h>

\wxheading{Remarks}

A mask may be associated with a \helpref{wxBitmap}{wxbitmap}. It is used in \helpref{wxDC::Blit}{wxdcblit} when
the source device context is a \helpref{wxMemoryDC}{wxmemorydc} with wxBitmap selected into it that
contains a mask.

\membersection{wxMask::wxMask}\label{wxmaskconstr}

\func{}{wxMask}{\void}

Default constructor.

\func{}{wxMask}{\param{const wxBitmap\& }{bitmap}}

Constructs a mask from a monochrome bitmap.

\pythonnote{This is the default constructor for wxMask in wxPython.}

\func{}{wxMask}{\param{const wxBitmap\& }{bitmap}, \param{const wxColour\& }{colour}}

Constructs a mask from a bitmap and a colour that indicates the background. Not
yet implemented for GTK.

\pythonnote{wxPython has an alternate wxMask constructor matching this
form called \tt{wxMaskColour}.}

\func{}{wxMask}{\param{const wxBitmap\& }{bitmap}, \param{int}{ index}}

Constructs a mask from a bitmap and a palette index that indicates the background. Not
yet implemented for GTK.

\wxheading{Parameters}

\docparam{bitmap}{A valid bitmap.}

\docparam{colour}{A colour specifying the transparency RGB values.}

\docparam{index}{Index into a palette, specifying the transparency colour.}

\membersection{wxMask::\destruct{wxMask}}

\func{}{\destruct{wxMask}}{\void}

Destroys the wxMask object and the underlying bitmap data.

\membersection{wxMask::Create}\label{wxmaskcreate}

\func{bool}{Create}{\param{const wxBitmap\& }{bitmap}}

Constructs a mask from a monochrome bitmap.

\func{bool}{Create}{\param{const wxBitmap\& }{bitmap}, \param{const wxColour\& }{colour}}

Constructs a mask from a bitmap and a colour that indicates the background. Not
yet implemented for GTK.

\func{bool}{Create}{\param{const wxBitmap\& }{bitmap}, \param{int}{ index}}

Constructs a mask from a bitmap and a palette index that indicates the background. Not
yet implemented for GTK.

\wxheading{Parameters}

\docparam{bitmap}{A valid bitmap.}

\docparam{colour}{A colour specifying the transparency RGB values.}

\docparam{index}{Index into a palette, specifying the transparency colour.}
