37This class encapsulates a platform-independent image. An image can be created
38from data, or using <code>wxBitmap.ConvertToImage</code>. An image can be loaded from
39a file in a variety of formats, and is extensible to new formats via image
40format handlers. Functions are available to set and get image bits, so it can
41be used for basic image manipulation.
42
43<p>The following image handlers are available. wxBMPHandler is always installed
44by default. To use other image formats, install the appropriate handler or use
45<code>wx.InitAllImageHandlers()</code>.

50<tr><td>wxPNGHandler</td> <td>For loading and saving.</td> </tr>
51<tr><td>wxJPEGHandler</td> <td>For loading and saving.</td> </tr>
52<tr><td>wxGIFHandler</td> <td>Only for loading, due to legal issues.</td> </tr>

63<p>When saving in PCX format, wxPCXHandler will count the number of different
64colours in the image; if there are 256 or less colours, it will save as 8 bit,
65else it will save as 24 bit.
66
67<p>Loading PNMs only works for ASCII or raw RGB images. When saving in PNM format,
68wxPNMHandler will always save as raw RGB.
