.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.

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 (\-)
|

|
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.

.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 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:
|
|
.sp 1
|
|
*customization: \-color
|
|
.sp 1
|
|
.br
|
|
This will cause bitmap to pick up the colors in the app-defaults color
|
|
customization file:

.SH 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
|
|
purpose 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.
