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 \func{}{wxBitmap}{\param{const wxImage\&}{ img}, \param{int}{ depth = -1}}
78
79 Creates bitmap object from the image. This has to be done
80 to actually display an image as you cannot draw an image directly on a window.
81 The resulting bitmap will use the provided colour depth (or that of the
82 current system if depth is -1) which entails that a colour reduction has
83 to take place.
84
85 When in 8-bit mode (PseudoColour mode), the GTK port will use a color cube created
86 on program start-up to look up colors. This ensures a very fast conversion, but
87 the image quality won't be perfect (and could be better for photo images using more
88 sophisticated dithering algorithms).
89
90 On Windows, if there is a palette present (set with SetPalette), it will be used when
91 creating the wxBitmap (most useful in 8-bit display mode). On other platforms,
92 the palette is currently ignored.
93
94 \wxheading{Parameters}
95
96 \docparam{bits}{Specifies an array of pixel values.}
97
98 \docparam{width}{Specifies the width of the bitmap.}
99
100 \docparam{height}{Specifies the height of the bitmap.}
101
102 \docparam{depth}{Specifies the depth of the bitmap. If this is omitted, the display depth of the
103 screen is used.}
104
105 \docparam{name}{This can refer to a resource name under MS Windows, or a filename under MS Windows and X.
106 Its meaning is determined by the {\it type} parameter.}
107
108 \docparam{type}{May be one of the following:
109
110 \twocolwidtha{5cm}
111 \begin{twocollist}
112 \twocolitem{\indexit{wxBITMAP\_TYPE\_BMP}}{Load a Windows bitmap file.}
113 \twocolitem{\indexit{wxBITMAP\_TYPE\_BMP\_RESOURCE}}{Load a Windows bitmap from the resource database.}
114 \twocolitem{\indexit{wxBITMAP\_TYPE\_GIF}}{Load a GIF bitmap file.}
115 \twocolitem{\indexit{wxBITMAP\_TYPE\_XBM}}{Load an X bitmap file.}
116 \twocolitem{\indexit{wxBITMAP\_TYPE\_XPM}}{Load an XPM bitmap file.}
117 \twocolitem{\indexit{wxBITMAP\_TYPE\_RESOURCE}}{Load a Windows resource name.}
118 \end{twocollist}
119
120 The validity of these flags depends on the platform and wxWindows configuration.
121 If all possible wxWindows settings are used, the Windows platform supports BMP file, BMP resource,
122 XPM data, and XPM. Under wxGTK, the available formats are BMP file, XPM data, XPM file, and PNG file.
123 Under wxMotif, the available formats are XBM data, XBM file, XPM data, XPM file.
124
125 In addition, wxBitmap can read all formats that \helpref{wxImage}{wximage} can, which currently include
126 wxBITMAP\_TYPE\_JPEG, wxBITMAP\_TYPE\_TIF, wxBITMAP\_TYPE\_PNG, wxBITMAP\_TYPE\_GIF, wxBITMAP\_TYPE\_PCX,
127 and wxBITMAP\_TYPE\_PNM. Of course, you must have wxImage handlers loaded. }
128
129 \docparam{img}{Platform-independent wxImage object.}
130
131 \wxheading{Remarks}
132
133 The first form constructs a bitmap object with no data; an assignment or another member function such as Create
134 or LoadFile must be called subsequently.
135
136 The second and third forms provide copy constructors. Note that these do not copy the
137 bitmap data, but instead a pointer to the data, keeping a reference count. They are therefore
138 very efficient operations.
139
140 The fourth form constructs a bitmap from data whose type and value depends on
141 the value of the {\it type} argument.
142
143 The fifth form constructs a (usually monochrome) bitmap from an array of pixel values, under both
144 X and Windows.
145
146 The sixth form constructs a new bitmap.
147
148 The seventh form constructs a bitmap from pixmap (XPM) data, if wxWindows has been configured
149 to incorporate this feature.
150
151 To use this constructor, you must first include an XPM file. For
152 example, assuming that the file {\tt mybitmap.xpm} contains an XPM array
153 of character pointers called mybitmap:
154
155 \begin{verbatim}
156 #include "mybitmap.xpm"
157
158 ...
159
160 wxBitmap *bitmap = new wxBitmap(mybitmap);
161 \end{verbatim}
162
163 The eighth form constructs a bitmap from a file or resource. {\it name} can refer
164 to a resource name under MS Windows, or a filename under MS Windows and X.
165
166 Under Windows, {\it type} defaults to wxBITMAP\_TYPE\_BMP\_RESOURCE.
167 Under X, {\it type} defaults to wxBITMAP\_TYPE\_XPM.

194 \membersection{wxBitmap::\destruct{wxBitmap}}
195
196 \func{}{\destruct{wxBitmap}}{\void}
197
198 Destroys the wxBitmap object and possibly the underlying bitmap data.
199 Because reference counting is used, the bitmap may not actually be
200 destroyed at this point - only when the reference count is zero will the
201 data be deleted.
202
203 If the application omits to delete the bitmap explicitly, the bitmap will be
204 destroyed automatically by wxWindows when the application exits.
205
206 Do not delete a bitmap that is selected into a memory device context.

230
231 \func{wxImage}{ConvertToImage}{\void}
232
233 Creates an image from a platform-dependent bitmap. This preserves
234 mask information so that bitmaps and images can be converted back
235 and forth without loss in that respect.
236
237 \membersection{wxBitmap::Create}\label{wxbitmapcreate}
238
239 \func{virtual bool}{Create}{\param{int}{ width}, \param{int}{ height}, \param{int}{ depth = -1}}
240
241 Creates a fresh bitmap. If the final argument is omitted, the display depth of
242 the screen is used.
243
244 \func{virtual bool}{Create}{\param{void*}{ data}, \param{int}{ type}, \param{int}{ width}, \param{int}{ height}, \param{int}{ depth = -1}}
245

260
261 \wxheading{Return value}
262
263 TRUE if the call succeeded, FALSE otherwise.
264
265 \wxheading{Remarks}
266
267 The first form works on all platforms. The portability of the second form depends on the

616 This is the base class for implementing bitmap file loading/saving, and bitmap creation from data.
617 It is used within wxBitmap and is not normally seen by the application.
618
619 If you wish to extend the capabilities of wxBitmap, derive a class from wxBitmapHandler
620 and add the handler using \helpref{wxBitmap::AddHandler}{wxbitmapaddhandler} in your
621 application initialisation.
