4
5This is the base class for implementing bitmap file loading/saving, and bitmap creation from data.
6It is used within wxBitmap and is not normally seen by the application.
7
8If you wish to extend the capabilities of wxBitmap, derive a class from wxBitmapHandler
9and add the handler using \helpref{wxBitmap::AddHandler}{wxbitmapaddhandler} in your
10application initialisation.

32\func{}{wxBitmapHandler}{\void}
33
34Default constructor. In your own default constructor, initialise the members
35m\_name, m\_extension and m\_type.

37\membersection{wxBitmapHandler::\destruct{wxBitmapHandler}}\label{wxbitmaphandlerdtor}
38
39\func{}{\destruct{wxBitmapHandler}}{\void}
40
41Destroys the wxBitmapHandler object.

44
45\func{virtual bool}{Create}{\param{wxBitmap* }{bitmap}, \param{const void*}{ data}, \param{int}{ type}, \param{int}{ width}, \param{int}{ height}, \param{int}{ depth = -1}}
46
47Creates a bitmap from the given data, which can be of arbitrary type. The wxBitmap object {\it bitmap} is
48manipulated by this function.
49
50\wxheading{Parameters}
51
52\docparam{bitmap}{The wxBitmap object.}
53
54\docparam{width}{The width of the bitmap in pixels.}
55
56\docparam{height}{The height of the bitmap in pixels.}
57
58\docparam{depth}{The depth of the bitmap in pixels. If this is -1, the screen depth is used.}
59
60\docparam{data}{Data whose type depends on the value of {\it type}.}
61
62\docparam{type}{A bitmap type identifier - see \helpref{wxBitmapHandler::wxBitmapHandler}{wxbitmapctor} for a list
63of possible values.}
64
65\wxheading{Return value}
66
67true if the call succeeded, false otherwise (the default).
