33 \membersection{wxBitmap::wxBitmap}\label{wxbitmapconstr}
34
35 \func{}{wxBitmap}{\void}
36
37 Default constructor.
38
39 \func{}{wxBitmap}{\param{const wxBitmap\& }{bitmap}}
40
41 Copy constructor.
42
43 \func{}{wxBitmap}{\param{void*}{ data}, \param{int}{ type}, \param{int}{ width}, \param{int}{ height}, \param{int}{ depth = -1}}
44
45 Creates a bitmap from the given data which is interpreted in platform-dependent
46 manner.
47
48 \func{}{wxBitmap}{\param{const char}{ bits[]}, \param{int}{ width}, \param{int}{ height}\\
49 \param{int}{ depth = 1}}
50
51 Creates a bitmap from an array of bits.
52
53 You should only use this function for monochrome bitmaps ({\it depth} 1) in
54 portable programs: in this case the {\it bits} parameter should contain an XBM
55 image.
56
57 For other bit depths, the behaviour is platform dependent: under Windows, the
58 data is passed without any changes to the underlying {\tt CreateBitmap()} API.
59 Under other platforms, only monochrome bitmaps may be created using this
60 constructor and \helpref{wxImage}{wximage} should be used for creating colour
61 bitmaps from static data.
62
63 \func{}{wxBitmap}{\param{int}{ width}, \param{int}{ height}, \param{int}{ depth = -1}}
64
65 Creates a new bitmap. A depth of -1 indicates the depth of the current screen
66 or visual. Some platforms only support 1 for monochrome and -1 for the current
67 colour setting.
68
69 \func{}{wxBitmap}{\param{const char**}{ bits}}
70
71 Creates a bitmap from XPM data.
72
73 \func{}{wxBitmap}{\param{const wxString\& }{name}, \param{long}{ type}}
74
75 Loads a bitmap from a file or resource.
76
77 \wxheading{Parameters}
78
79 \docparam{bits}{Specifies an array of pixel values.}
80
81 \docparam{width}{Specifies the width of the bitmap.}
82
83 \docparam{height}{Specifies the height of the bitmap.}
84
85 \docparam{depth}{Specifies the depth of the bitmap. If this is omitted, the display depth of the
86 screen is used.}
87
88 \docparam{name}{This can refer to a resource name under MS Windows, or a filename under MS Windows and X.
89 Its meaning is determined by the {\it type} parameter.}
90
91 \docparam{type}{May be one of the following:
92
93 \twocolwidtha{5cm}
94 \begin{twocollist}
95 \twocolitem{\indexit{wxBITMAP\_TYPE\_BMP}}{Load a Windows bitmap file.}
96 \twocolitem{\indexit{wxBITMAP\_TYPE\_BMP\_RESOURCE}}{Load a Windows bitmap from the resource database.}
97 \twocolitem{\indexit{wxBITMAP\_TYPE\_GIF}}{Load a GIF bitmap file.}
98 \twocolitem{\indexit{wxBITMAP\_TYPE\_XBM}}{Load an X bitmap file.}
99 \twocolitem{\indexit{wxBITMAP\_TYPE\_XPM}}{Load an XPM bitmap file.}
100 \twocolitem{\indexit{wxBITMAP\_TYPE\_RESOURCE}}{Load a Windows resource name.}
101 \end{twocollist}
102
103 The validity of these flags depends on the platform and wxWindows configuration.
104 If all possible wxWindows settings are used, the Windows platform supports BMP file, BMP resource,
105 XPM data, and XPM. Under wxGTK, the available formats are BMP file, XPM data, XPM file, and PNG file.
106 Under wxMotif, the available formats are XBM data, XBM file, XPM data, XPM file.
107
108 In addition, wxBitmap can read all formats that \helpref{wxImage}{wximage} can, which currently include
109 wxBITMAP\_TYPE\_JPEG, wxBITMAP\_TYPE\_TIF, wxBITMAP\_TYPE\_PNG, wxBITMAP\_TYPE\_GIF, wxBITMAP\_TYPE\_PCX,
110 and wxBITMAP\_TYPE\_PNM. Of course, you must have wxImage handlers loaded. }
111
112 \wxheading{Remarks}
113
114 The first form constructs a bitmap object with no data; an assignment or another member function such as Create
115 or LoadFile must be called subsequently.
116
117 The second and third forms provide copy constructors. Note that these do not copy the
118 bitmap data, but instead a pointer to the data, keeping a reference count. They are therefore
119 very efficient operations.
120
121 The fourth form constructs a bitmap from data whose type and value depends on
122 the value of the {\it type} argument.
123
124 The fifth form constructs a (usually monochrome) bitmap from an array of pixel values, under both
125 X and Windows.
126
127 The sixth form constructs a new bitmap.
128
129 The seventh form constructs a bitmap from pixmap (XPM) data, if wxWindows has been configured
130 to incorporate this feature.
131
132 To use this constructor, you must first include an XPM file. For
133 example, assuming that the file {\tt mybitmap.xpm} contains an XPM array
134 of character pointers called mybitmap:
135
136 \begin{verbatim}
137 #include "mybitmap.xpm"
138
139 ...
140
141 wxBitmap *bitmap = new wxBitmap(mybitmap);
142 \end{verbatim}
143
144 The eighth form constructs a bitmap from a file or resource. {\it name} can refer
145 to a resource name under MS Windows, or a filename under MS Windows and X.
146
147 Under Windows, {\it type} defaults to wxBITMAP\_TYPE\_BMP\_RESOURCE.
148 Under X, {\it type} defaults to wxBITMAP\_TYPE\_XPM.

176
177 \func{}{\destruct{wxBitmap}}{\void}
178
179 Destroys the wxBitmap object and possibly the underlying bitmap data.
180 Because reference counting is used, the bitmap may not actually be
181 destroyed at this point - only when the reference count is zero will the
182 data be deleted.
183
184 If the application omits to delete the bitmap explicitly, the bitmap will be
185 destroyed automatically by wxWindows when the application exits.
186
187 Do not delete a bitmap that is selected into a memory device context.

214 Creates a fresh bitmap. If the final argument is omitted, the display depth of
215 the screen is used.
216
217 \func{virtual bool}{Create}{\param{void*}{ data}, \param{int}{ type}, \param{int}{ width}, \param{int}{ height}, \param{int}{ depth = -1}}

588 This is the base class for implementing bitmap file loading/saving, and bitmap creation from data.
589 It is used within wxBitmap and is not normally seen by the application.
590
591 If you wish to extend the capabilities of wxBitmap, derive a class from wxBitmapHandler
592 and add the handler using \helpref{wxBitmap::AddHandler}{wxbitmapaddhandler} in your
593 application initialisation.
