BITMAP(1)							     BITMAP(1)

NAME
       bitmap,	bmtoa, atobm - bitmap editor and converter utilities for the X
       Window System

SYNOPSIS
       bitmap [ -options ... ] [ filename ] [ basename ]

       bmtoa [ -chars ... ] [ filename ]

       atobm [ -chars cc ] [ -name variable ] [ -xhot number ] [ -yhot	number
       ] [ filename ]

DESCRIPTION
       The  bitmap  program is a rudimentary tool for creating or editing rec‐
       tangular 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.

       The bmtoa and atobm filters convert bitmap 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.

COMMAND LINE OPTIONS
       Bitmap supports the standard X  Toolkit	command	 line  arguments  (see
       X(1)).  The following additional arguments are supported as well.

       -size WIDTHxHEIGHT
	   Specifies size of the grid in squares.

       -sw dimension
	   Specifies the width of squares in pixels.

       -sh dimension
	   Specifies the height of squares in pixels.

       -gt dimension
	   Grid	 tolerance.  If the square dimensions fall below the specified
	   value, grid will be automatically turned off.

       -grid, +grid
	   Turns on or off the grid lines.

       -axes, +axes
	   Turns on or off the major axes.

       -dashed, +dashed
	   Turns on or off dashing for the frame and grid lines.

       -stippled, +stippled
	   Turns on or off stippling of highlighted squares.

       -proportional, +proportional
	   Turns proportional mode on or off.  If  proportional	 mode  is  on,
	   square  width  is  equal to square height.  If proportional mode is
	   off, bitmap will use the smaller square  dimension,	if  they  were
	   initially different.

       -dashes filename
	   Specifies the bitmap to be used as a stipple for dashing.

       -stipple filename
	   Specifies the bitmap to be used as a stipple for highlighting.

       -hl color
	   Specifies the color used for highlighting.

       -fr color
	   Specifies the color used for the frame and grid lines.

       filename
	   Specifies  the  bitmap to be initially loaded into the program.  If
	   the file does not exist, bitmap will assume it is a new file.

       basename
	   Specifies the basename to be used in the C code output file.	 If it
	   is  different  than	the  basename in the working file, bitmap will
	   change it when saving the file.

       Bmtoa accepts the following option:

       -chars cc
	   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.

       Atobm accepts the following options:

       -chars cc
	   This option specifies the pair of characters to use when converting
	   string bitmaps into arrays of numbers.  The first character	repre‐
	   sents  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.

       -name variable
	   This option specifies the variable name to be used when writing out
	   the	bitmap	file.  The default is to use the basename of the file‐
	   name command line argument or leave it blank if the standard	 input
	   is read.

       -xhot number
	   This	 option specifies the X coordinate of the hotspot.  Only posi‐
	   tive values are allowed.  By default,  no  hotspot  information  is
	   included.

       -yhot number
	   This	 option specifies the Y coordinate of the hotspot.  Only posi‐
	   tive values are allowed.  By default,  no  hotspot  information  is
	   included.

USAGE
       Bitmap  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  normally	 and inverted, can be obtained by pressing Meta-I key.
       You are free to move the image popup out of the way to  continue	 edit‐
       ing.   Pressing	the  left  mouse  button in the popup window or Meta-I
       again will remove the real size bitmap image.

       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 symmet‐
       ric cursors (such as crosses or bullseyes), this is usually at the cen‐
       ter.

       Bitmaps	are stored as small C code fragments suitable for including in
       applications.  They provide an array of bits as well as	symbolic  con‐
       stants  giving  the width, height, and hot spot (if specified) that may
       be used in creating cursors, icons, and tiles.

EDITING
       To edit a bitmap image simply click on one of the buttons with  drawing
       commands	 (Point,  Curve,  Line,	 Rectangle, 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  set‐
       ting  a	bit  in	 the bitmap image to 1.	 Clearing a grid square corre‐
       sponds 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.

		 MouseButton1	     Set
		 MouseButton2	     Invert
		 MouseButton3	     Clear
		 MouseButton4	     Clear
		 MouseButton5	     Clear

       This  default  behavior	can  be changed by setting the button function
       resources.  An example is provided below.

		 bitmap*button1Function: Set
		 bitmap*button2Function: Clear
		 bitmap*button3Function: Invert
		 etc.

       The button function applies to all drawing commands, including copying,
       moving and pasting, flood filling and setting the hot spot.

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.

       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.

       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.

       Invert
	   This command inverts all  bits  in  the  bitmap  image.   The  grid
	   squares will be inverted appropriately.  Pressing I inside the bit‐
	   map window has the same effect.

       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  Up,
	   Down,  Left,	 Right, Rotate, Flip, Cut, 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 Shift-MouseButton1 and dragging out	 a  rectangle  in  the
	   grid window.	 Pressing Shift-MouseButton2 will mark the entire grid
	   area.

       Unmark
	   This command will cause the marked area to vanish.  The same effect
	   can be achieved by pressing Shift-MouseButton3.

       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,  Copy
	   behaves  just  like	Mark  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,  Copy	will  assume that you wish to mark a different
	   region of the bitmap image, thus it will behave like Mark again.

       Move
	   This command is used to move an area of the grid from one  location
	   to  another.	  Its behavior resembles the behavior of Copy command,
	   except that the marked area will be moved instead of copied.

       Flip Horizontally
	   This command will flip the bitmap image with respect to  the	 hori‐
	   zontal  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.

       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.

       Flip Vertically
	   This command will flip the bitmap image with respect to the	verti‐
	   cal	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.

       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.

       Fold
	   This command will fold the bitmap image so that the	opposite  cor‐
	   ners	 become	 adjacent.  This is useful when creating bitmap images
	   for tiling.	Pressing F inside  the	bitmap	window	has  the  same
	   effect.

       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.

       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.

       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.

       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.

       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, depend‐
	   ing on the speed of your  system  and  frequency  of	 mouse	motion
	   events.

       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 con‐
	   tinuous.  If your system is slow or bitmap receives very few	 mouse
	   motion events, it might behave quite strangely.

       Line
	   This	 command  will	change	the gird squares in a line between two
	   squares.  Once you press a mouse button in the grid window,	bitmap
	   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.

       Rectangle
	   This command will change the gird squares in	 a  rectangle  between
	   two	squares.   Once	 you  press a mouse button in the grid window,
	   bitmap 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 disap‐
	   pear.

       Filled Rectangle
	   This command is identical to Rectangle, except at the end the  rec‐
	   tangle will be filled rather than outlined.

       Circle
	   This	 command  will change the gird squares in a circle between two
	   squares.  Once you press a mouse button in the grid window,	bitmap
	   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.

       Filled Circle
	   This command is identical to Circle, except at the end  the	circle
	   will be filled rather than outlined.

       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.

       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.

       Clear Hot Spot
	   This command removes any designated hot spot from the bitmap image.

       Undo
	   This command will undo the last executed  command.	It  has	 depth
	   one, that is, pressing Undo after Undo will undo itself.

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 parame‐
       ters, such as size, basename, filename etc.

       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.

       Load
	   This command is used to load a new bitmap file into the bitmap edi‐
	   tor.	 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.

       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 loca‐
	   tion where you want to insert the new file.

       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.

       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.

       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.

       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.

       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.

       Basename
	   This	 command  is  used  to change the basename, if a different one
	   from the specified filename is desired.

       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.

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.

       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.

       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.

       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.

       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.

       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.

       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.

       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.

       Cut This commands cuts the contents of the highlighted image area  into
	   the internal cut and paste buffer.

       Copy
	   This command copies the contents of the highlighted image area into
	   the internal cut and paste buffer.

       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.

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.

WIDGETS
       Below is the widget structure of the bitmap  application.   Indentation
       indicates  hierarchical	structure.   The  widget  class	 name is given
       first, followed by the widget instance name.  All  widgets  except  the

COLORS
       If you would like bitmap to be viewable in color, include the following
       in the #ifdef COLOR section of the file you read with xrdb:

       *customization:		       -color

       This will cause bitmap to pick up the colors in the app-defaults	 color
       customization file:

	   /usr/X11R6/share/X11/app-defaults/Bitmap-color

BITMAP WIDGET
       Bitmap widget is a stand-alone widget for editing raster images.	 It is
       not designed to edit large images, although it may be used in that pur‐
       pose  as	 well.	 It can be freely incorporated with other applications
       and used as a standard editing tool.  The following are	the  resources
       provided by the bitmap widget.
