+.SH DESCRIPTION
+The \fIbitmap\fP program is a rudimentary tool for creating or editing
+rectangular images made up of 1's and 0's. Bitmaps are used in X for
+defining clipping regions, cursor shapes, icon shapes, and tile and
+stipple patterns.
+.PP
+The \fIbmtoa\fP and \fIatobm\fP filters convert \fIbitmap\fP files (FILE
+FORMAT) to and from ASCII strings. They are most commonly used to
+quickly print out bitmaps and to generate versions for including in text.
+.SH COMMAND LINE OPTIONS
+\fIBitmap\fP supports the standard X Toolkit command line arguments
+(see \fIX\fP(1)). The following additional arguments are supported as well.
+.TP 4
+.B \-size\fI WIDTHxHEIGHT\fP
+Specifies size of the grid in squares.
+.TP 4
+.B \-sw\fI dimension\fP
+Specifies the width of squares in pixels.
+.TP 4
+.B \-sh\fI dimension\fP
+Specifies the height of squares in pixels.
+.TP 4
+.B \-gt\fI dimension\fP
+Grid tolerance. If the square dimensions fall below the specified
+value, grid will be automatically turned off.
+.TP 4
+.B \-grid, +grid
+./&.B \-grid\fI on/off\fP
+Turns on or off the grid lines.
+.TP 4
+.B \-axes, +axes
+./&./&.B \-axes\fI on/off\fP
+Turns on or off the major axes.
+.TP 4
+.B \-dashed, +dashed
+./&.B \-dashed\fI on/off\fP
+Turns on or off dashing for the frame and grid lines.
+.TP 4
+.B \-stippled, +stippled
+./&.B \-stippled\fI on/off\fP
+Turns on or off stippling of highlighted squares.
+.TP 4
+.B \-proportional, +proportional\fI
+./&.B \-proportional\fI on/off\fP
+Turns proportional mode on or off. If proportional mode is on,
+square width is equal to square height. If proportional mode is
+off,\fI bitmap\fP will use the smaller square dimension, if they
+were initially different.
+.TP 4
+.B \-dashes\fI filename\fP
+Specifies the bitmap to be used as a stipple for dashing.
+.TP 4
+.B \-stipple\fI filename\fP
+Specifies the bitmap to be used as a stipple for highlighting.
+.TP 4
+.B \-hl\fI color\fP
+Specifies the color used for highlighting.
+.TP 4
+.B \-fr\fI color\fP
+Specifies the color used for the frame and grid lines.
+.TP 4
+.B filename
+Specifies the bitmap to be initially loaded into the program.
+If the file does not exist,\fI bitmap\fP will assume it is a new file.
+.TP 4
+.B basename
+Specifies the basename to be used in the C code output file.
+If it is different than the basename in the working file,\fI bitmap\fP
+will change it when saving the file.
+.PP
+\fIBmtoa\fP accepts the following option:
+.TP 4
+.B \-chars \fIcc\fP
+This option specifies the pair of characters to use in the string version
+of the bitmap. The first character is used for 0 bits and the second character
+is used for 1 bits. The default is to use dashes (\-) for 0's and sharp signs
+(#) for 1's.
+.PP
+\fIAtobm\fP accepts the following options:
+.TP 4
+.B \-chars \fIcc\fP
+This option specifies the pair of characters to use when converting string
+bitmaps into arrays of numbers. The first character represents a 0 bit and
+the second character represents a 1 bit. The default is to use dashes (\-)
+for 0's and sharp signs (#) for 1's.
+.TP 4
+.B \-name \fIvariable\fP
+This option specifies the variable name to be used when writing out the
+bitmap file. The default is to use the basename of the \fIfilename\fP command
+line argument or leave it blank if the standard input is read.
+.TP 4
+.B \-xhot \fInumber\fP
+This option specifies the X coordinate of the hotspot. Only positive values
+are allowed. By default, no hotspot information is included.
+.TP 4
+.B \-yhot \fInumber\fP
+This option specifies the Y coordinate of the hotspot. Only positive values
+are allowed. By default, no hotspot information is included.
+.SH USAGE
+\fIBitmap\fP displays grid in which each square represents a single
+bit in the picture being edited. Actual size of the bitmap image, as
+it would appear normaly and inverted, can be obtained by pressing\fB
+Meta-I\fP key. You are free to move the image popup out of the way to
+continue editing. Pressing the left mouse button in the popup window
+or\fB Meta-I\fP again will remove the real size bitmap image.
+.PP
+If the bitmap is to be used for defining a cursor, one of the squares
+in the images may be designated as the hot spot. This determines
+where the cursor is actually pointing. For cursors with sharp tips
+(such as arrows or fingers), this is usually at the end of the tip;
+for symmetric cursors (such as crosses or bullseyes), this is usually
+at the center.
+.PP
+Bitmaps are stored as small C code fragments suitable for including in
+applications. They provide an array of bits as well as symbolic
+constants giving the width, height, and hot spot (if specified) that
+may be used in creating cursors, icons, and tiles.
+.SH EDITING
+To edit a bitmap image simply click on one of the buttons with drawing
+commands (\fBPoint, Curve, Line, Rectangle,\fP etc.) and move the
+pointer into the bitmap grid window. Press one of the buttons on your
+mouse and the appropriate action will take place. You can either set,
+clear or invert the gird squares. Setting a grid square corresponds
+to setting a bit in the bitmap image to 1. Clearing a grid square
+corresponds to setting a bit in the bitmap image to 0. Inverting a
+grid square corresponds to changing a bit in the bitmap image from 0 to
+1 or 1 to 0, depending what its previous state was. The
+default behavior of mouse buttons is as specified below.
+.sp
+.nf
+ MouseButton1 Set
+ MouseButton2 Invert
+ MouseButton3 Clear
+ MouseButton4 Clear
+ MouseButton5 Clear
+.fi
+.sp
+This default behavior can be changed by setting the button function
+resources. An example is provided below.
+.sp
+.nf
+ bitmap*button1Function: Set
+ bitmap*button2Function: Clear
+ bitmap*button3Function: Invert
+ etc.
+.fi
+.sp
+The button function applies to all drawing commands, including copying,
+moving and pasting, flood filling and setting the hot spot.
+.SH DRAWING COMMANDS
+Here is the list of drawing commands accessible through the
+buttons at the left side of the application's window. Some commands
+can be aborted by pressing A inside the bitmap window, allowing the
+user to select different guiding points where applicable.
+.TP 4
+.B Clear
+This command clears all bits in the bitmap image. The grid squares
+will be set to the background color. Pressing C inside the bitmap
+window has the same effect.
+.TP 4
+.B Set
+This command sets all bits in the bitmap image. The grid squares
+will be set to the foreground color. Pressing S inside the bitmap
+window has the same effect.
+.TP 4
+.B Invert
+This command inverts all bits in the bitmap image. The grid squares
+will be inverted appropriately. Pressing I inside the bitmap window
+has the same effect.
+.TP 4
+.B Mark
+This command is used to mark an area of the grid by dragging out a
+rectangular shape in the highlighting color. Once the area is marked,
+it can be operated on by a number of commands (see \fBUp, Down, Left,
+Right, Rotate, Flip, Cut,\fP etc.) Only one marked area can be present
+at any time. If you attempt to mark another area, the old mark will
+vanish. The same effect can be achieved by pressing\fB
+Shift-MouseButton1\fP and dragging out a rectangle in the grid window.
+Pressing\fB Shift-MouseButton2\fP will mark the entire grid area.
+.TP 4
+.B Unmark
+This command will cause the marked area to vanish. The same effect can
+be achieved by pressing\fB Shift-MouseButton3\fP.
+.TP 4
+.B Copy
+This command is used to copy an area of the grid from one location to
+another. If there is no marked grid area displayed,\fB Copy\fP
+behaves just like\fB Mark\fP described above. Once there is a marked
+grid area displayed in the highlighting color, this command has two
+alternative behaviors. If you click a mouse button inside the marked
+area, you will be able to drag the rectangle that represents the
+marked area to the desired location. After you release the mouse
+button, the area will be copied. If you click outside the marked
+area,\fB Copy\fP will assume that you wish to mark a different region of
+the bitmap image, thus it will behave like\fB Mark\fP again.
+.TP 4
+.B Move
+This command is used to move an area of the grid from one location to
+another. Its behavior resembles the behavior of\fB Copy\fP command,
+except that the marked area will be moved instead of copied.
+.TP 4
+.B Flip Horizontally
+This command will flip the bitmap image with respect to the horizontal axes.
+If a marked area of the grid is highlighted, it will operate only
+inside the marked area. Pressing H inside the bitmap window has the
+same effect.
+.TP 4
+.B Up
+This command moves the bitmap image one pixel up.
+If a marked area of the grid is highlighted, it will operate only
+inside the marked area. Pressing UpArrow inside the bitmap window has the
+same effect.
+.TP 4
+.B Flip Vertically
+This command will flip the bitmap image with respect to the vertical axes.
+If a marked area of the grid is highlighted, it will operate only
+inside the marked area. Pressing V inside the bitmap window has the
+same effect.
+.TP 4
+.B Left
+This command moves the bitmap image one pixel to the left.
+If a marked area of the grid is highlighted, it will operate only
+inside the marked area. Pressing LeftArrow inside the bitmap window has
+the same effect.
+.TP 4
+.B Fold
+This command will fold the bitmap image so that the opposite corners
+become adjacent. This is useful when creating bitmap images for
+tiling. Pressing F inside the bitmap window has the same effect.
+.TP 4
+.B Right
+This command moves the bitmap image one pixel to the right.
+If a marked area of the grid is highlighted, it will operate only
+inside the marked area. Pressing RightArrow inside the bitmap window
+has the same effect.
+.TP 4
+.B Rotate Left
+This command rotates the bitmap image 90 degrees to the left (counter
+clockwise.)
+If a marked area of the grid is highlighted, it will operate only
+inside the marked area. Pressing L inside the bitmap window has the
+same effect.
+.TP 4
+.B Down
+This command moves the bitmap image one pixel down.
+If a marked area of the grid is highlighted, it will operate only
+inside the marked area. Pressing DownArrow inside the bitmap window
+has the same effect.
+.TP 4
+.B Rotate Right
+This command rotates the bitmap image 90 degrees to the right (clockwise.)
+If a marked area of the grid is highlighted, it will operate only
+inside the marked area. Pressing R inside the bitmap window has the
+same effect.
+.TP 4
+.B Point
+This command will change the grid squares underneath the mouse pointer if
+a mouse button is being pressed down. If you drag the mouse button
+continuously, the line may not be continuous, depending on the speed of your
+system and frequency of mouse motion events.
+.TP 4
+.B Curve
+This command will change the grid squares underneath the mouse pointer if
+a mouse button is being pressed down. If you drag the mouse button
+continuously, it will make sure that the line is continuous. If your system
+is slow or\fI bitmap\fP receives very few mouse motion events, it might
+behave quite strangely.
+.TP 4
+.B Line
+This command will change the gird squares in a line between two squares.
+Once you press a mouse button in the grid window,\fI bitmap\fP will
+highlight the line from the square where the mouse button was initially
+pressed to the square where the mouse pointer is located. By releasing the
+mouse button you will cause the change to take effect, and the highlighted
+line will disappear.
+.TP 4
+.B Rectangle
+This command will change the gird squares in a rectangle between two squares.
+Once you press a mouse button in the grid window,\fI bitmap\fP will
+highlight the rectangle from the square where the mouse button was initially
+pressed to the square where the mouse pointer is located. By releasing the
+mouse button you will cause the change to take effect, and the highlighted
+rectangle will disappear.
+.TP 4
+.B Filled Rectangle
+This command is identical to\fB Rectangle\fP, except at the end the
+rectangle will be filled rather than outlined.
+.TP 4
+.B Circle
+This command will change the gird squares in a circle between two squares.
+Once you press a mouse button in the grid window,\fI bitmap\fP will
+highlight the circle from the square where the mouse button was initially
+pressed to the square where the mouse pointer is located. By releasing the
+mouse button you will cause the change to take effect, and the highlighted
+circle will disappear.
+.TP 4
+.B Filled Circle
+This command is identical to\fB Circle\fP, except at the end the
+circle will be filled rather than outlined.
+.TP 4
+.B Flood Fill
+This command will flood fill the connected area underneath the mouse
+pointer when you click on the desired square. Diagonally adjacent
+squares are not considered to be connected.
+.TP 4
+.B Set Hot Spot
+This command designates one square in the grid as the hot spot if this
+bitmap image is to be used for defining a cursor. Pressing a mouse button
+in the desired square will cause a diamond shape to be displayed.
+.TP 4
+.B Clear Hot Spot
+This command removes any designated hot spot from the bitmap image.
+.TP 4
+.B Undo
+This command will undo the last executed command. It has depth one,
+that is, pressing\fB Undo\fP after\fB Undo\fP will undo itself.
+.SH FILE MENU
+The File menu commands can be accessed by pressing the File button and
+selecting the appropriate menu entry, or by pressing Ctrl key with
+another key. These commands deal with files and global bitmap
+parameters, such as size, basename, filename etc.
+.TP 4
+.B New
+This command will clear the editing area and prompt for the name of
+the new file to be edited. It will not load in the new file.
+.TP 4
+.B Load
+This command is used to load a new bitmap file into the bitmap editor.
+If the current image has not been saved, user will be asked whether to
+save or ignore the changes. The editor can edit only one file at a
+time. If you need interactive editing, run a number of editors and
+use cut and paste mechanism as described below.
+.TP 4
+.B Insert
+This command is used to insert a bitmap file into the image
+being currently edited. After being prompted for the filename,
+click inside the grid window and drag the outlined rectangle to the
+location where you want to insert the new file.
+.TP 4
+.B Save
+This command will save the bitmap image. It will not prompt for the
+filename unless it is said to be <none>. If you leave the filename
+undesignated or \-, the output will be piped to stdout.
+.TP 4
+.B Save As
+This command will save the bitmap image after prompting for a new
+filename. It should be used if you want to change the filename.
+.TP 4
+.B Resize
+This command is used to resize the editing area to the new number of
+pixels. The size should be entered in the WIDTHxHEIGHT format. The
+information in the image being edited will not be lost unless the new
+size is smaller that the current image size. The editor was not
+designed to edit huge files.
+.TP 4
+.B Rescale
+This command is used to rescale the editing area to the new width and
+height. The size should be entered in the WIDTHxHEIGHT format. It will
+not do antialiasing and information will be lost if you rescale to the
+smaller sizes. Feel free to add you own algorithms for better rescaling.
+.TP 4
+.B Filename
+This command is used to change the filename without changing the basename
+nor saving the file. If you specify \- for a filename, the output will
+be piped to stdout.
+.TP 4
+.B Basename
+This command is used to change the basename, if a different one from
+the specified filename is desired.
+.TP 4
+.B Quit
+\This command will terminate the bitmap application. If the file was
+not saved, user will be prompted and asked whether to save the image
+or not. This command is preferred over killing the process.
+.SH EDIT MENU
+The Edit menu commands can be accessed by pressing the Edit button and
+selecting the appropriate menu entry, or by pressing Meta key with
+another key. These commands deal with editing facilities such as
+grid, axes, zooming, cut and paste, etc.
+.TP 4
+.B Image
+This command will display the image being edited and its inverse in its
+actual size in a separate window. The window can be moved away to continue
+with editing. Pressing the left mouse button in the image window will
+cause it to disappear from the screen.
+.TP 4
+.B Grid
+This command controls the grid in the editing area. If the grid spacing
+is below the value specified by gridTolerance resource (8 by default),
+the grid will be automatically turned off. It can be enforced by explicitly
+activating this command.
+.TP 4
+.B Dashed
+This command controls the stipple for drawing the grid lines. The stipple
+specified by dashes resource can be turned on or off by activating this
+command.
+.TP 4
+.B Axes
+This command controls the highlighting of the main axes of the image
+being edited. The actual lines are not part of the image. They are
+provided to aid user when constructing symmetrical images, or whenever
+having the main axes highlighted helps your editing.
+.TP 4
+.B Stippled
+This command controls the stippling of the highlighted areas of the
+bitmap image. The stipple specified by stipple resource can be turned on
+or off by activating this command.
+.TP 4
+.B Proportional
+This command controls the proportional mode. If the proportional mode
+is on, width and height of all image squares are forced to be equal,
+regardless of the proportions of the bitmap window.
+.TP 4
+.B Zoom
+This command controls the zoom mode. If there is a marked area of the
+image already displayed, bitmap will automatically zoom into it. Otherwise,
+user will have to highlight an area to be edited in the zoom mode and
+bitmap will automatically switch into it. One can use all the editing
+commands and other utilities in the zoom mode. When you zoom out, undo
+command will undo the whole zoom session.
+.TP 4
+.B Cut
+This commands cuts the contents of the highlighted image area into the
+internal cut and paste buffer.
+.TP 4
+.B Copy
+This command copies the contents of the highlighted image area into the
+internal cut and paste buffer.
+.TP 4
+.B Paste
+This command will check if there are any other bitmap applications with
+a highlighted image area, or if there is something in the internal cut
+and paste buffer and copy it to the image. To place the copied image,
+click in the editing window and drag the outlined image to the position
+where you want to place i, and then release the button.
+.SH CUT AND PASTE
+Bitmap supports two cut and paste mechanisms; the internal cut and
+paste and the global X selection cut and paste. The internal cut and
+paste is used when executing copy and move drawing commands and also
+cut and copy commands from the edit menu. The global X selection cut
+and paste is used whenever there is a highlighted area of a bitmap
+image displayed anywhere on the screen. To copy a part of image from
+another bitmap editor simply highlight the desired area by using the
+Mark command or pressing the shift key and dragging the area with the
+left mouse button. When the selected area becomes highlighted, any
+other applications (such as xterm, etc.) that use primary selection
+will discard their selection values and unhighlight the appropriate
+information. Now, use the Paste command for the Edit menu or control
+mouse button to copy the selected part of image into another (or the
+same) bitmap application. If you attempt to do this without a visible
+highlighted image area, the bitmap will fall back to the internal cut
+and paste buffer and paste whatever was there stored at the moment.
+.SH WIDGETS
+Below is the widget structure of the \fIbitmap\fP
+application. Indentation indicates hierarchical structure. The
+widget class name is given first, followed by the widget instance
+name. All widgets except the bitmap widget are from the standard
+Athena widget set.
