\section{\class{wxImage}}\label{wximage}

This class encapsulates a platform-independent image. An image can be created
from data, or using the constructor taking a wxBitmap object. An image
can be loaded from a file in a variety of formats, and is extensible to new formats
via image format handlers. Functions are available to set and get image bits, so
it can be used for basic image manipulation.

A wxImage cannot (currently) be drawn directly to a \helpref{wxDC}{wxdc}. Instead, 
a platform-specific \helpref{wxBitmap}{wxbitmap} object must be created from it using
the \helpref{ConvertToBitmap}{wximageconverttobitmap} function. This bitmap can then
be drawn in a device context, using \helpref{wxDC::DrawBitmap}{wxdcdrawbitmap}.

One colour value of the image may be used as a mask colour which will lead to the automatic
creation of a \helpref{wxMask}{wxmask} object associated to the bitmap object.

\wxheading{Available image handlers}

The following image handlers are available. {\bf wxBMPHandler} is always
installed by default. To use other image formats, install the appropiate
handler with \helpref{wxImage::AddHandler}{wximageaddhandler} or
\helpref{wxInitAllImageHandlers}{wxinitallimagehandlers}.

\twocolwidtha{5cm}%
\begin{twocollist}
\twocolitem{{\bf \indexit{wxBMPHandler}}}{Only for loading, always installed.}
\twocolitem{{\bf \indexit{wxPNGHandler}}}{For loading and saving.}
\twocolitem{{\bf \indexit{wxJPEGHandler}}}{For loading and saving.}
\twocolitem{{\bf \indexit{wxGIFHandler}}}{Only for loading, due to legal issues.}
\twocolitem{{\bf \indexit{wxPCXHandler}}}{For loading and saving (see below).}
\twocolitem{{\bf \indexit{wxPNMHandler}}}{For loading and saving (see below).}
\twocolitem{{\bf \indexit{wxTIFFHandler}}}{For loading and saving.}
\end{twocollist}

When saving in PCX format, {\bf wxPCXHandler} will count the number of
different colours in the image; if there are 256 or less colours, it will
save as 8 bit, else it will save as 24 bit.

Loading PNMs only works for ASCII or raw RGB images. When saving in
PNM format, {\bf wxPNMHandler} will always save as raw RGB.

\membersection{wxImage::\destruct{wxImage}}

\func{}{\destruct{wxImage}}{\void}

Destructor.

\membersection{wxImage::AddHandler}\label{wximageaddhandler}

\func{static void}{AddHandler}{\param{wxImageHandler*}{ handler}}

Adds a handler to the end of the static list of format handlers.

\docparam{handler}{A new image format handler object. There is usually only one instance
of a given handler class in an application session.}

This function is called by wxWindows on exit.

\membersection{wxImage::ConvertToBitmap}\label{wximageconverttobitmap}

\constfunc{wxBitmap}{ConvertToBitmap}{\void}

Converts the image to a platform-specific bitmap object. 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 colour depth of the current system 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).

\func{wxImage \&}{Rescale}{\param{int}{ width}, \param{int}{ height}}

Changes the size of the image in-place: after a call to this function, the
image will have the given width and height.

Returns the (modified) image itself.

\wxheading{See also}

\helpref{Scale}{wximagescale}

\membersection{wxImage::Rotate}\label{wximagererotate}

\func{wxImage}{Rotate}{\param{double}{ angle}, \param{const wxPoint\& }{rotationCentre},
 \param{bool}{ interpolating = TRUE}, \param{wxPoint*}{ offsetAfterRotation = NULL}}

Rotates the image about the given point, by {\it angle} radians. Passing TRUE
to {\it interpolating} results in better image quality, but is slower.

Returns the rotated image, leaving this image intact.

\membersection{wxImage::Scale}\label{wximagescale}

\constfunc{wxImage}{Scale}{\param{int}{ width}, \param{int}{ height}}

Returns a scaled version of the image. This is also useful for
scaling bitmaps in general as the only other way to scale bitmaps
is to blit a wxMemoryDC into another wxMemoryDC.

It may be mentioned that the GTK port uses this function internally
to scale bitmaps when using mapping mode in wxDC. 

Example:

\begin{verbatim}
    // get the bitmap from somewhere
    wxBitmap bmp = ...;

    // rescale it to have size of 32*32
    if ( bmp.GetWidth() != 32 || bmp.GetHeight() != 32 )
    {
        wxImage image(bmp);
        bmp = image.Scale(32, 32).ConvertToBitmap();

        // another possibility:
        image.Rescale(32, 32);
        bmp = image;
    }

\end{verbatim}

\wxheading{See also}

\helpref{Rescale}{wximagerescale}

\membersection{wxImage::SetData}\label{wximagesetdata}

\func{void}{SetData}{\param{unsigned char*}{data}}

Sets the image data without performing checks. The data given must have
the size (width*height*3) or results will be unexpected. Don't use this
method if you aren't sure you know what you are doing.

\membersection{wxImage::SetMask}\label{wximagesetmask}

\func{void}{SetMask}{\param{bool}{ hasMask = TRUE}}

Specifies whether there is a mask or not. The area of the mask is determined by the current mask colour.

\membersection{wxImage::SetMaskColour}\label{wximagesetmaskcolour}

\func{void}{SetMaskColour}{\param{unsigned char }{red}, \param{unsigned char }{blue}, \param{unsigned char }{green}}

Sets the mask colour for this image (and tells the image to use the mask).

\membersection{wxImage::SetRGB}\label{wximagesetrgb}

\func{void}{SetRGB}{\param{int }{x}, \param{int }{y}, \param{unsigned char }{red}, \param{unsigned char }{blue}, \param{unsigned char }{green}}

Sets the pixel at the given coordinate. This routine performs bounds-checks
for the coordinate so it can be considered a safe way to manipulate the
data, but in some cases this might be too slow so that the data will have to
be set directly. In that case you will have to get access to the image data 
using the \helpref{GetData}{wximagegetdata} method.

\membersection{wxImage::operator $=$}

\func{wxImage\& }{operator $=$}{\param{const wxImage\& }{image}}

Assignment operator. This operator does not copy any data, but instead
passes a pointer to the data in {\it image} and increments a reference
counter. It is a fast operation.

\wxheading{Parameters}

\docparam{image}{Image to assign.}

\wxheading{Return value}

Returns 'this' object.

\membersection{wxImage::operator $==$}

\func{bool}{operator $==$}{\param{const wxImage\& }{image}}

Equality operator. This operator tests whether the internal data pointers are
equal (a fast test).

\wxheading{Parameters}

\docparam{image}{Image to compare with 'this'}

\wxheading{Return value}

Returns TRUE if the images were effectively equal, FALSE otherwise.

\membersection{wxImage::operator $!=$}

\func{bool}{operator $!=$}{\param{const wxImage\& }{image}}

Inequality operator. This operator tests whether the internal data pointers are
unequal (a fast test).

\wxheading{Parameters}

\docparam{image}{Image to compare with 'this'}

\wxheading{Return value}

Returns TRUE if the images were unequal, FALSE otherwise.

\section{\class{wxImageHandler}}\label{wximagehandler}

This is the base class for implementing image file loading/saving, and image creation from data.
It is used within wxImage and is not normally seen by the application.

If you wish to extend the capabilities of wxImage, derive a class from wxImageHandler
and add the handler using \helpref{wxImage::AddHandler}{wximageaddhandler} in your
application initialisation.

\wxheading{Note (Legal Issue)}

This software is based in part on the work of the Independent JPEG Group.

(Applies when wxWindows is linked with JPEG support. wxJPEGHandler uses libjpeg
created by IJG.)
