This is the base class for implementing bitmap file loading/saving, and

|
|
|
bitmap creation from data.

2008-03-08 13:52:38 +00:00

It is used within wxBitmap and is not normally seen by the application.

If you wish to extend the capabilities of wxBitmap, derive a class from
|
2008-03-25 22:06:48 +00:00
|
|
|
wxBitmapHandler and add the handler using wxBitmap::AddHandler() in your

This class encapsulates the concept of a platform-dependent bitmap,
|
|
|
|
either monochrome or colour or colour with alpha channel support.
|
2008-09-21 20:03:14 +00:00
|
|
|
|
2008-04-10 13:21:20 +00:00
|
|
|
If you need direct access the bitmap data instead going through
|
|
|
|
drawing to it using wxMemoryDC you need to use the wxPixelData
|
|
|
|
class (either wxNativePixelData for RGB bitmaps or wxAlphaPixelData
|
|
|
|
for bitmaps with an additionaly alpha channel).
|

|
|
|
@note
|
2008-03-17 00:47:38 +00:00
|
|
|
Many wxBitmap functions take a @e type parameter, which is a value of the
|
|
|
|
::wxBitmapType enumeration.
|
2008-03-15 18:15:46 +00:00
|
|
|
The validity of those values depends however on the platform where your program
|
|
|
|
is running and from the wxWidgets configuration.
|
|
|
|
If all possible wxWidgets settings are used, the Windows platform supports BMP file,
|
|
|
|
BMP resource, XPM data, and XPM.
|
|
|
|
Under wxGTK, the available formats are BMP file, XPM data, XPM file, and PNG file.
|
|
|
|
Under wxMotif, the available formats are XBM data, XBM file, XPM data, XPM file.
|
|
|
|
In addition, wxBitmap can load and save all formats that wxImage; see wxImage for
|
|
|
|
more info. Of course, you must have wxImage handlers loaded.

created on program start-up to look up colors. This ensures a very fast conversion,

more sophisticated dithering algorithms).

On Windows, if there is a palette present (set with SetPalette), it will be

used when creating the wxBitmap (most useful in 8-bit display mode).

On other platforms, the palette is currently ignored.
