- A bitmap is an image whose pixels can display either of two colors or be
- transparent. A bitmap image is defined by four things: a background
- color, a foreground color, and two bitmaps, called the _s_o_u_r_c_e and the
- _m_a_s_k. Each of the bitmaps specifies 0/1 values for a rectangular array
- of pixels, and the two bitmaps must have the same dimensions. For pixels
- where the mask is zero, the image displays nothing, producing a
- transparent effect. For other pixels, the image displays the foreground
- color if the source data is one and the background color if the source
- data is zero.

- Like all images, bitmaps are created using the iiiimmmmaaaaggggeeee ccccrrrreeeeaaaatttteeee command.
- Bitmaps support the following _o_p_t_i_o_n_s:
-
- ----bbbbaaaacccckkkkggggrrrroooouuuunnnndddd _c_o_l_o_r
- Specifies a background color for the image in any of the standard
- ways accepted by Tk. If this option is set to an empty string then
- the background pixels will be transparent. This affect is achieved
- by using the source bitmap as the mask bitmap, ignoring any
- ----mmmmaaaasssskkkkddddaaaattttaaaa or ----mmmmaaaasssskkkkffffiiiilllleeee options.
-
- ----ddddaaaattttaaaa _s_t_r_i_n_g
- Specifies the contents of the source bitmap as a string. The string
- must adhere to X11 bitmap format (e.g., as generated by the bbbbiiiittttmmmmaaaapppp
- program). If both the ----ddddaaaattttaaaa and ----ffffiiiilllleeee options are specified, the
- ----ddddaaaattttaaaa option takes precedence.
-
- ----ffffiiiilllleeee _n_a_m_e
- _n_a_m_e gives the name of a file whose contents define the source
- bitmap. The file must adhere to X11 bitmap format (e.g., as
- generated by the bbbbiiiittttmmmmaaaapppp program).
-
- ----ffffoooorrrreeeeggggrrrroooouuuunnnndddd _c_o_l_o_r
- Specifies a foreground color for the image in any of the standard
- ways accepted by Tk.
-
- ----mmmmaaaasssskkkkddddaaaattttaaaa _s_t_r_i_n_g
- Specifies the contents of the mask as a string. The string must
- adhere to X11 bitmap format (e.g., as generated by the bbbbiiiittttmmmmaaaapppp
- program). If both the ----mmmmaaaasssskkkkddddaaaattttaaaa and ----mmmmaaaasssskkkkffffiiiilllleeee options are
- specified, the ----mmmmaaaasssskkkkddddaaaattttaaaa option takes precedence.

- When a bitmap image is created, Tk also creates a new command whose name
- is the same as the image. This command may be used to invoke various
- operations on the image. It has the following general form:
-
- _i_m_a_g_e_N_a_m_e _o_p_t_i_o_n ?_a_r_g _a_r_g ...?
-
- _O_p_t_i_o_n and the _a_r_gs determine the exact behavior of the command. The
- following commands are possible for bitmap images:
-
- _i_m_a_g_e_N_a_m_e ccccggggeeeetttt _o_p_t_i_o_n
- Returns the current value of the configuration option given by
- _o_p_t_i_o_n. _O_p_t_i_o_n may have any of the values accepted by the iiiimmmmaaaaggggeeee
- ccccrrrreeeeaaaatttteeee bbbbiiiittttmmmmaaaapppp command.
-
- _i_m_a_g_e_N_a_m_e ccccoooonnnnffffiiiigggguuuurrrreeee ?_o_p_t_i_o_n? ?_v_a_l_u_e _o_p_t_i_o_n _v_a_l_u_e ...?
- Query or modify the configuration options for the image. If no
- _o_p_t_i_o_n is specified, returns a list describing all of the available
- options for _i_m_a_g_e_N_a_m_e (see TTTTkkkk____CCCCoooonnnnffffiiiigggguuuurrrreeeeIIIInnnnffffoooo for information on the
- format of this list). If _o_p_t_i_o_n is specified with no _v_a_l_u_e, then
- the command returns a list describing the one named option (this
- list will be identical to the corresponding sublist of the value
- returned if no _o_p_t_i_o_n is specified). If one or more _o_p_t_i_o_n-_v_a_l_u_e
- pairs are specified, then the command modifies the given option(s)
- to have the given value(s); in this case the command returns an
- empty string. _O_p_t_i_o_n may have any of the values accepted by the
- iiiimmmmaaaaggggeeee ccccrrrreeeeaaaatttteeee bbbbiiiittttmmmmaaaapppp command.
