DESCRIPTION

The bitmap program is a rudimentary tool for creating or editing rect-

angular 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.

CCOOMMMMAANNDD LLIINNEE OOPPTTIIOONNSS Bitmap supports the standard X Toolkit command line arguments (see X(1)). The following additional arguments are supported as well.

-ssiizzee WIDTHxHEIGHT

Specifies size of the grid in squares.

-ssww dimension

Specifies the width of squares in pixels.

-sshh dimension

Specifies the height of squares in pixels.

-ggtt dimension

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

-ggrriidd,, ++ggrriidd

Turns on or off the grid lines.

-aaxxeess,, ++aaxxeess

Turns on or off the major axes.

-ddaasshheedd,, ++ddaasshheedd

Turns on or off dashing for the frame and grid lines.

-ssttiipppplleedd,, ++ssttiipppplleedd

Turns on or off stippling of highlighted squares.

-pprrooppoorrttiioonnaall,, ++pprrooppoorrttiioonnaall

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.

-ddaasshheess filename

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

-ssttiippppllee filename

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

-hhll color

Specifies the color used for highlighting.

-ffrr color

Specifies the color used for the frame and grid lines. ffiilleennaammee

Specifies the bitmap to be initially loaded into the program. If

the file does not exist, bitmap will assume it is a new file.

bbaasseennaammee 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:

-cchhaarrss 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:

-cchhaarrss 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.

-nnaammee 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.

-xxhhoott number

This option specifies the X coordinate of the hotspot. Only posi-

tive values are allowed. By default, no hotspot information is included.

-yyhhoott number

This option specifies the Y coordinate of the hotspot. Only posi-

tive values are allowed. By default, no hotspot information is included. UUSSAAGGEE 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 normaly and inverted, can be obtained by pressing MMeettaa-II 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 MMeettaa-II

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. EEDDIITTIINNGG

To edit a bitmap image simply click on one of the buttons with drawing

commands (PPooiinntt,, CCuurrvvee,, LLiinnee,, RReeccttaannggllee,, 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. DDRRAAWWIINNGG CCOOMMMMAANNDDSS 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. CClleeaarr

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.

SSeett 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. IInnvveerrtt

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. MMaarrkk 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 UUpp,, DDoowwnn,, LLeefftt,, RRiigghhtt,, RRoottaattee,, FFlliipp,, CCuutt,, 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 SShhiifftt-MMoouusseeBBuuttttoonn11 and dragging out a rectangle in the

grid window. Pressing SShhiifftt-MMoouusseeBBuuttttoonn22 will mark the entire grid

area. UUnnmmaarrkk This command will cause the marked area to vanish. The same effect

can be achieved by pressing SShhiifftt-MMoouusseeBBuuttttoonn33.

CCooppyy This command is used to copy an area of the grid from one location to another. If there is no marked grid area displayed, CCooppyy behaves just like MMaarrkk 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, CCooppyy will assume that you wish to mark a different

region of the bitmap image, thus it will behave like MMaarrkk again.

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

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.

UUpp 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. FFlliipp VVeerrttiiccaallllyy

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. LLeefftt

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. FFoolldd

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. RRiigghhtt

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. RRoottaattee LLeefftt

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.

DDoowwnn

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. RRoottaattee RRiigghhtt

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. PPooiinntt 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. CCuurrvvee 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. LLiinnee 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. RReeccttaannggllee 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. FFiilllleedd RReeccttaannggllee

This command is identical to RReeccttaannggllee, except at the end the rec-

tangle will be filled rather than outlined. CCiirrccllee 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. FFiilllleedd CCiirrccllee This command is identical to CCiirrccllee, except at the end the circle will be filled rather than outlined. FFlloooodd FFiillll 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. SSeett HHoott SSppoott 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. CClleeaarr HHoott SSppoott

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

UUnnddoo This command will undo the last executed command. It has depth one, that is, pressing UUnnddoo after UUnnddoo will undo itself. FFIILLEE MMEENNUU 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. NNeeww 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. LLooaadd

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. IInnsseerrtt

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. SSaavvee

This command will save the bitmap image. It will not prompt for

the filename unless it is said to be . If you leave the

filename undesignated or -, the output will be piped to stdout.

SSaavvee AAss

This command will save the bitmap image after prompting for a new

filename. It should be used if you want to change the filename. RReessiizzee 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. RReessccaallee 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. FFiilleennaammee 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. BBaasseennaammee This command is used to change the basename, if a different one from the specified filename is desired. QQuuiitt

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. EEDDIITT MMEENNUU 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. IImmaaggee 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. GGrriidd 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. DDaasshheedd 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. AAxxeess 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. SSttiipppplleedd 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. PPrrooppoorrttiioonnaall 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.

ZZoooomm 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. CCuutt This commands cuts the contents of the highlighted image area into the internal cut and paste buffer. CCooppyy This command copies the contents of the highlighted image area into the internal cut and paste buffer. PPaassttee

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. CCUUTT AANNDD PPAASSTTEE 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. WWIIDDGGEETTSS

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:

BBIITTMMAAPP WWIIDDGGEETT

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
