- The wxBitmap class encapsulates the concept of a platform-dependent bitmap,
- either monochrome or colour. Platform-specific methods for creating a
- wxBitmap object from an existing file are catered for, and
- this is an occasion where conditional compilation will sometimes be
- required.

- A bitmap created dynamically or loaded from a file can be selected
- into a memory device context (instance of #wxMemoryDC). This

- using wxDC::Blit, or to be used as a drawing surface.

- There is also a corresponding #wxBITMAP macro which allows
- to create the bitmaps in much the same way as #wxICON creates
- icons. It assumes that bitmaps live in resources under Windows or OS2 and XPM
- files under all other platforms (for XPMs, the corresponding file must be
- included before this macro is used, of course, and the name of the bitmap
- should be the same as the resource name under Windows with @c _xpm
- suffix). For example:

- wxBitmap bmp(wxBITMAP(bmpname));
+@code
+// an easy and portable way to create a bitmap
+wxBitmap bmp(wxBITMAP(bmpname));
- // which is roughly equivalent to the following

- #else // Unix
- wxBitmap bmp(bmpname_xpm, wxBITMAP_TYPE_XPM);

+ wxBitmap bmp("bmpname", wxBITMAP_TYPE_BMP_RESOURCE);

- You should always use wxICON and wxBITMAP macros because they work for any
- platform (unlike the code above which doesn't deal with wxMac, wxX11, ...) and
- are more short and clear than versions with @c #ifdefs. Even better,
- use the same XPMs on all platforms.

- The following lists the formats handled on different platforms. Note
- that missing or partially-implemented formats are automatically supplemented
- by the #wxImage to load the data, and then converting
- it to wxBitmap form. Note that using wxImage is the preferred way to
- load images in wxWidgets, with the exception of resources (XPM-files or
- native Windows resources).

- Writing an image format handler for wxImage is also far easier than writing
- one for wxBitmap, because wxImage has exactly one format on all platforms
- whereas wxBitmap can store pixel data very differently, depending on colour
- depths and platform.
