|
|
either monochrome or colour or colour with alpha channel support.

\membersection{wxBitmap::wxBitmap}\label{wxbitmapctor}
|
|
|
|
\func{}{wxBitmap}{\void}
|
|
|
|
Default constructor.
|
|
|
|
\func{}{wxBitmap}{\param{const wxBitmap\& }{bitmap}}
|
|
|
|
Copy constructor. Note that this does not take a fresh copy of the data,
|
|
but instead makes the internal data point to {\it bitmap}'s data. So
|
|
changing one bitmap will change the other. To make a real copy, you can
|
|
use:
|
|
|
|
\begin{verbatim}
|
|
wxBitmap newBitmap = oldBitmap.GetSubBitmap(
|
|
wxRect(0, 0, oldBitmap.GetWidth(), oldBitmap.GetHeight()));
|
|
\end{verbatim}
|
|
|
|
\func{}{wxBitmap}{\param{void*}{ data}, \param{int}{ type}, \param{int}{ width}, \param{int}{ height}, \param{int}{ depth = -1}}
|
|
|
|
Creates a bitmap from the given data which is interpreted in platform-dependent
|
|
manner.
|
|
|
|
\func{}{wxBitmap}{\param{const char}{ bits[]}, \param{int}{ width}, \param{int}{ height}\\
|
|
\param{int}{ depth = 1}}
|
|
|
|
Creates a bitmap from an array of bits.
|
|
|
|
You should only use this function for monochrome bitmaps ({\it depth} 1) in
|
|
portable programs: in this case the {\it bits} parameter should contain an XBM
|
|
image.
|
|
|
|
For other bit depths, the behaviour is platform dependent: under Windows, the
|
|
data is passed without any changes to the underlying {\tt CreateBitmap()} API.
|
|
Under other platforms, only monochrome bitmaps may be created using this
|
|
constructor and \helpref{wxImage}{wximage} should be used for creating colour
|
|
bitmaps from static data.
|
|
|
|
\func{}{wxBitmap}{\param{int}{ width}, \param{int}{ height}, \param{int}{ depth = -1}}
|
|
|
|
Creates a new bitmap. A depth of -1 indicates the depth of the current screen
|
|
or visual. Some platforms only support 1 for monochrome and -1 for the current
|
|
colour setting. Beginning with version 2.5.4 of wxWidgets a depth of 32 including
|
|
an alpha channel is supported under MSW, Mac and GTK+.
|
|
|
|
\func{}{wxBitmap}{\param{const char**}{ bits}}
|
|
|
|
Creates a bitmap from XPM data.
|
|
|
|
\func{}{wxBitmap}{\param{const wxString\& }{name}, \param{long}{ type}}
|
|
|
|
Loads a bitmap from a file or resource.
|
|
|
|
\func{}{wxBitmap}{\param{const wxImage\&}{ img}, \param{int}{ depth = -1}}
|
|
|
|
Creates bitmap object from the image. This has to be done
|
|
to actually display an image as you cannot draw an image directly on a window.
|
|
The resulting bitmap will use the provided colour depth (or that of the
|
|
current system if depth is -1) which entails that a colour reduction has
|
|
to take place.
|
|
|
|
When in 8-bit mode (PseudoColour mode), the GTK port will use a color cube created
|
|
on program start-up to look up colors. This ensures a very fast conversion, but
|
|
the image quality won't be perfect (and could be better for photo images using 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.
|
|
|
|
\wxheading{Parameters}
|
|
|
|
\docparam{bits}{Specifies an array of pixel values.}
|
|
|
|
\docparam{width}{Specifies the width of the bitmap.}
|
|
|
|
\docparam{height}{Specifies the height of the bitmap.}
|
|
|
|
\docparam{depth}{Specifies the depth of the bitmap. If this is omitted, the display depth of the
|
|
screen is used.}
|
|
|
|
\docparam{name}{This can refer to a resource name under MS Windows, or a filename under MS Windows and X.
|
|
Its meaning is determined by the {\it type} parameter.}
|
|
|
|
\docparam{type}{May be one of the following:
|
|
|
|
\twocolwidtha{5cm}
|
|
\begin{twocollist}
|
|
\twocolitem{\indexit{wxBITMAP\_TYPE\_BMP}}{Load a Windows bitmap file.}
|
|
\twocolitem{\indexit{wxBITMAP\_TYPE\_BMP\_RESOURCE}}{Load a Windows bitmap resource from the executable. Windows only.}
|
|
\twocolitem{\indexit{wxBITMAP\_TYPE\_PICT\_RESOURCE}}{Load a PICT image resource from the executable. Mac OS only.}
|
|
\twocolitem{\indexit{wxBITMAP\_TYPE\_GIF}}{Load a GIF bitmap file.}
|
|
\twocolitem{\indexit{wxBITMAP\_TYPE\_XBM}}{Load an X bitmap file.}
|
|
\twocolitem{\indexit{wxBITMAP\_TYPE\_XPM}}{Load an XPM bitmap file.}
|
|
\end{twocollist}
|
|
|
|
The validity of these flags depends on the platform and 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 read all formats that \helpref{wxImage}{wximage} can, which currently include
|
|
wxBITMAP\_TYPE\_JPEG, wxBITMAP\_TYPE\_TIF, wxBITMAP\_TYPE\_PNG, wxBITMAP\_TYPE\_GIF, wxBITMAP\_TYPE\_PCX,
|
|
and wxBITMAP\_TYPE\_PNM. Of course, you must have wxImage handlers loaded. }
|
|
|
|
\docparam{img}{Platform-independent wxImage object.}
|
|
|
|
\wxheading{Remarks}
|
|
|
|
The first form constructs a bitmap object with no data; an assignment or another member function such as Create
|
|
or LoadFile must be called subsequently.
|
|
|
|
The second and third forms provide copy constructors. Note that these do not copy the
|
|
bitmap data, but instead a pointer to the data, keeping a reference count. They are therefore
|
|
very efficient operations.
|
|
|
|
The fourth form constructs a bitmap from data whose type and value depends on
|
|
the value of the {\it type} argument.
|
|
|
|
The fifth form constructs a (usually monochrome) bitmap from an array of pixel values, under both
|
|
X and Windows.
|
|
|
|
The sixth form constructs a new bitmap.
|
|
|
|
The seventh form constructs a bitmap from pixmap (XPM) data, if wxWidgets has been configured
|
|
to incorporate this feature.
|
|
|
|
To use this constructor, you must first include an XPM file. For
|
|
example, assuming that the file {\tt mybitmap.xpm} contains an XPM array
|
|
of character pointers called mybitmap:
|
|
|
|
\begin{verbatim}
|
|
#include "mybitmap.xpm"
|
|
|
|
...
|
|
|
|
wxBitmap *bitmap = new wxBitmap(mybitmap);
|
|
\end{verbatim}
|
|
|
|
The eighth form constructs a bitmap from a file or resource. {\it name} can refer
|
|
to a resource name under MS Windows, or a filename under MS Windows and X.
|
|
|
|
Under Windows, {\it type} defaults to wxBITMAP\_TYPE\_BMP\_RESOURCE.
|
|
Under X, {\it type} defaults to wxBITMAP\_TYPE\_XPM.

\membersection{wxBitmap::\destruct{wxBitmap}}\label{wxbitmapdtor}
|
|
|
|
\func{}{\destruct{wxBitmap}}{\void}
|
|
|
|
Destroys the wxBitmap object and possibly the underlying bitmap data.
|
|
Because reference counting is used, the bitmap may not actually be
|
|
destroyed at this point - only when the reference count is zero will the
|
|
data be deleted.
|
|
|
|
If the application omits to delete the bitmap explicitly, the bitmap will be
|
|
destroyed automatically by wxWidgets when the application exits.
|
|
|
|
Do not delete a bitmap that is selected into a memory device context.
|
|
|
|
\membersection{wxBitmap::AddHandler}\label{wxbitmapaddhandler}

|
|
|
|
\func{wxImage}{ConvertToImage}{\void}
|
|
|
|

|
|
|
|
\func{wxBitmap\& }{operator $=$}{\param{const wxBitmap\& }{bitmap}}
|
|
|
|
Assignment operator. This operator does not copy any data, but instead
|
|
passes a pointer to the data in {\it bitmap} and increments a reference
|
|
counter. It is a fast operation.
|
|
|
|
\wxheading{Parameters}
|
|
|
|
\docparam{bitmap}{Bitmap to assign.}

|
|
Equality operator. This operator tests whether the internal data pointers are
|
|
equal (a fast test).
|
|
|
|
\wxheading{Parameters}
|
|
|
|
\docparam{bitmap}{Bitmap to compare with 'this'}
|
|
|
|
\wxheading{Return value}
