\subsection{Supported bitmap file formats}\label{supportedbitmapformats}
The following lists the formats handled on different platforms. Note
that missing or partially-implemented formats can be supplemented
by using \helpref{wxImage}{wximage} to load the data, and then converting
it to wxBitmap form.
that missing or partially-implemented formats are automatically supplemented
by the \helpref{wxImage}{wximage} to load the data, and then converting
it to wxBitmap form. Note that using wxImage is the preferred way to
load images in wxWindows, with the exception of resources (XPM-files or
native Windows resources). Writing an image format handler for wxImage
is also far easier than writing one for wxBitmap, because wxImage has
exactly one format on all platforms wheras wxBitmap can store pixel data
very differently, depending on colour depths and platform.
