<div class="textblock"><p>This class encapsulates the concept of a platform-dependent bitmap, either monochrome or colour or colour with alpha channel support. </p>
<p>If you need direct access the bitmap data instead going through drawing to it using <a class="el" href="classwx_memory_d_c.html" title="A memory device context provides a means to draw graphics onto a bitmap.">wxMemoryDC</a> you need to use the <a class="el" href="classwx_pixel_data.html" title="A class template with ready to use implementations for getting direct and efficient access to wxBitma...">wxPixelData</a> class (either wxNativePixelData for RGB bitmaps or wxAlphaPixelData for bitmaps with an additionally alpha channel).</p>
<p>Note that many <a class="el" href="classwx_bitmap.html" title="This class encapsulates the concept of a platform-dependent bitmap, either monochrome or colour or co...">wxBitmap</a> functions take a <em>type</em> parameter, which is a value of the <a class="el" href="gdicmn_8h.html#a90a1eb6d85b5044a99b706fd979f27f5" title="Bitmap type flags.">wxBitmapType</a> enumeration. 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:</p>
<ul>
<li>wxMSW supports BMP and ICO files, BMP and ICO resources;</li>
<li>wxGTK supports any file supported by gdk-pixbuf;</li>
<li>wxMac supports PICT resources;</li>
<li>wxX11 supports XPM files, XPM data, XBM data;</li>
</ul>
<p>In addition, <a class="el" href="classwx_bitmap.html" title="This class encapsulates the concept of a platform-dependent bitmap, either monochrome or colour or co...">wxBitmap</a> can load and save all formats that <a class="el" href="classwx_image.html" title="This class encapsulates a platform-independent image.">wxImage</a> can; see <a class="el" href="classwx_image.html" title="This class encapsulates a platform-independent image.">wxImage</a> for more info. Of course, you must have loaded the <a class="el" href="classwx_image.html" title="This class encapsulates a platform-independent image.">wxImage</a> handlers (see <a class="el" href="group__group__funcmacro__appinitterm.html#ga27f6c78d5d13374a28022b7bd44c6823" title="Initializes all available image handlers.">wxInitAllImageHandlers()</a> and <a class="el" href="classwx_image.html#ab39fb3747dfb8c2d444eff9fe41fa205" title="Register an image handler.">wxImage::AddHandler</a>). Note that all available wxBitmapHandlers for a given wxWidgets port are automatically loaded at startup so you won't need to use <a class="el" href="classwx_bitmap.html#a6418825ad15574229188e0c5f97a4f3a" title="Adds a handler to the end of the static list of format handlers.">wxBitmap::AddHandler</a>.</p>
<p>More on the difference between <a class="el" href="classwx_image.html" title="This class encapsulates a platform-independent image.">wxImage</a> and <a class="el" href="classwx_bitmap.html" title="This class encapsulates the concept of a platform-dependent bitmap, either monochrome or colour or co...">wxBitmap</a>: <a class="el" href="classwx_image.html" title="This class encapsulates a platform-independent image.">wxImage</a> is just a buffer of RGB bytes with an optional buffer for the alpha bytes. It is all generic, platform independent and image file format independent code. It includes generic code for scaling, resizing, clipping, and other manipulations of the image data. OTOH, <a class="el" href="classwx_bitmap.html" title="This class encapsulates the concept of a platform-dependent bitmap, either monochrome or colour or co...">wxBitmap</a> is intended to be a wrapper of whatever is the native image format that is quickest/easiest to draw to a DC or to be the target of the drawing operations performed on a <a class="el" href="classwx_memory_d_c.html" title="A memory device context provides a means to draw graphics onto a bitmap.">wxMemoryDC</a>. By splitting the responsibilities between wxImage/wxBitmap like this then it's easier to use generic code shared by all platforms and image types for generic operations and platform specific code where performance or compatibility is needed.</p>
