\subsubsection
{
Images
}
Bitmap/Pixelmap images can be created through the subclasses of
\class
{
Tkinter.Image
}
:
\begin{itemize}
\item
\class
{
BitmapImage
}
can be used for X11 bitmap data.
\item
\class
{
PhotoImage
}
can be used for GIF and PPM/PGM color bitmaps.
\end{itemize}
Either type of image is created through either the
\code
{
file
}
or the
\code
{
data
}
option (other options are available as well).
The image object can then be used whereever an
\code
{
image
}
option is
supported by some widget (e.g. labels, buttons, menus). In these
cases, Tk will not keep a reference to the image. When the last Python
reference to the image object is deleted, the image data is deleted as
well, and Tk will display an empty box wheerever the image was used.
