.SH SYNOPSIS
.B idraw
.RI [ options ]
.RI [ file ]
.SH DESCRIPTION
Idraw is a drawing editor that lets you create and edit drawings made
up of graphics like text, lines, splines, rectangles, polygons, and
ellipses.  Drawings are stored in files that can be printed on a
PostScript printer.  You can can open an existing drawing when
starting up idraw by typing a file name on the command line.

Idraw displays a portrait or landscape view of an 8.5 by 11 inch page
in its \fIdrawing area\fP.  In a column along the drawing area's left
side is a set of \fIdrawing tool\fP icons, and above the drawing area
is a set of pull-down menus containing \fIcommands\fP.  A panner in the
lower left corner lets you pan and zoom the the drawing area.  Along
the top is a set of indicators that display editing information.
.SH "DRAWING TOOLS"
You must engage a tool before you can use it.  You engage a tool by
clicking on its icon or by typing the character below and to the right
of its icon.  The icon of the drawing tool that's engaged appears in
inverted colors.  Once engaged, you use the tool by clicking the left
mouse button in the drawing area.

The
.BR Select ,
.BR Move ,
.BR Scale ,
.BR Stretch ,
.BR Rotate ,
and
.B Alter
tools manipulate existing graphics.
.B Magnify 
makes a part of the view expand to fill the entire view.
.BR Text ,
.BR Line ,
.BR Multiline ,
.BR "Open Spline" ,
.BR Ellipse ,
.BR Rectangle ,
.BR Polygon ,
and
.B Closed Spline
create new graphics.  Each tool works as follows:
.TP 15
.B Select
Select a graphic, unselecting all others.  A graphic is selected if
its \fIhandles\fP are visible.  Handles are small inverse-video
squares that either surround the graphic or demarcate its important
points (such as the endpoints of a line). If you hold down the shift
key, \fBSelect\fP \fIextends\fP the selection: it selects the
unselected graphic (or unselects the selected graphic) you clicked on
but does not unselect other selections.  Clicking anywhere other than
on a graphic unselects everything; you may also drag a rubberband
rectangle around a group of graphics to select all of them at once.
.I Shortcut:
the right mouse button invokes
.B Select
while the mouse is in the drawing area.
.TP
.B Move
Move graphics from one spot to another.
.I Shortcut:
the middle mouse button invokes
.B Move
while the mouse is in the drawing area.
.TP
.B Scale
Scale graphics about their centers.
.TP
.B Stretch
Stretch graphics vertically or horizontally while tying down the
opposite edge.
.TP
.B Rotate
Rotate graphics about their centers according to the angle between two
radii: the one defined by the original clicking point and the one
defined by the current dragging point.
.TP
.B Alter
Modify a graphic's structure.  This tool's effect is described below for
each graphic.
.TP
.B Magnify
Magnify a portion of the drawing specified by sweeping out a
rectangular area.  Idraw will magnify the area to occupy the entire
screen, if possible.
.TP
.B Text
Create some text.  Left-click to position the first line of text, and
then type as much text as you want.  You may use emacs-style
keystrokes to edit the text as well as enter it.  You can leave text
editing mode by typing ESC or by simply clicking somewhere else.
The Alter tool lets you edit the text in an existing text graphic.
.TP
.B Line
Create a line.  The shift key constrains the line to lie on either the
vertical or the horizontal axis.
You may left-click with the Alter tool on either endpoint
of a line to move the endpoint to a new location.
.TP
.B "Multiline"
Create a set of connected lines.  The shift key constrains each
segment to lie on either the vertical or the horizontal axis.  Each
left-click starts a new segment (i.e., adds a vertex); each
right-click removes the last vertex added.  The middle button
finalizes the multiline.  The Alter tool lets you move, add, and
remove vertices from an existing multiline.
.TP
.B "Open Spline"
Create an open B-spline.  The shift key constrains each control point
to lie on either the vertical or the horizontal axis with the
preceding point.  Each left-click adds a control point; each
right-click removes the last control point added.  The middle button
finalizes the spline.  The Alter tool lets you move, add, and
remove control points from an existing open spline.
.TP
.B Ellipse
Create an ellipse.  The shift key constrains the ellipse to the shape
of a circle.  The Alter tool does not affect ellipses.
.TP
.B Rectangle
Create a rectangle.  The shift key constrains the rectangle to the
shape of a square.  The Alter tool lets you move the rectangle's
corners independently to form a four-sided polygon.
.TP
.B Polygon
Create a polygon.  The shift key constrains each side to lie on either
the vertical or the horizontal axis.  Each left-click starts a new
segment (i.e., adds a vertex); each right-click removes the last
vertex added.  The middle button finalizes the polygon.  The Alter
tool lets you move, add, and remove vertices from an existing polygon.
.TP
.B "Closed Spline"
Create a closed B-spline.  The shift key constrains each control point
to lie on either the vertical or the horizontal axis with the
preceding point.  Each left-click adds a control point; each
right-click removes the last control point added.  The middle button
finalizes the spline.  The Alter tool lets you move, add, and remove
control points from an existing closed spline.

horizontal or vertical axes.
.TP
.BR "90 Clockwise" ", " "90 CounterCW"
Rotate the selected graphics 90 degrees clockwise or counterclockwise.
.TP
.BR "Precise Move..." ", " "Precise Scale..." ", " "Precise Rotate..."
Move, scale, or rotate graphics by exact amounts that you type in a
dialog box.  You can specify movements in pixels, points, centimeters,
or inches.  Scalings are specified in terms of magnification factors
in the horizontal and vertical dimensions. Rotations are in degrees.
.PP
The
.B Structure
menu contains the following commands to modify the structure of the
drawing, that is, the order in which  graphics are drawn:
.TP 15
.B Group
Nest the selected graphics in a newly created picture.  A picture is
just a graphic that contains other graphics.
.B Group
allows you to build hierarchies of graphics.
.TP
.B Ungroup
Dissolve any selected pictures.
.TP
.B Bring To Front
Bring the selected graphics to the front of the drawing so that they
are drawn on top of (after) other graphics.
.TP
.B Send To Back
Send the selected graphics to the back of the drawing so that they are
drawn behind (before) other graphics.
.PP
The
.B Font
menu contains a set of fonts in which to display text.  When you set
the current font from the menu, you will also set all the selected
graphics' fonts to that font.  A font indicator in the upper right
corner displays the current font.
.PP
The
.B Brush
menu contains a set of brushes with which to draw lines.  When you set
the current brush from the menu, you will also set all the selected
graphics' brushes to that brush.  The nonexistent brush draws
invisible lines and non-outlined graphics.  The arrowhead brushes add
arrowheads to either or both ends of lines, multilines, and open
splines. A brush indicator in the upper left corner displays the
current brush.
.PP
The
.B Pattern
menu contains a set of patterns with which to fill graphics but not
text.  Text always appears solid, but you can use a different color
than black to get a halftoned shade.  When you set the current pattern
from the menu, you will also set all the selected graphics' patterns
to that pattern.  The nonexistent pattern draws unfilled graphics,
while the other patterns draw graphics filled with a bitmap or a
halftoned shade.
.PP
The
.B FgColor
and
.B BgColor
menus contains a set of colors with which to draw graphics and text.
When you set the current foreground or background color from the
FgColor or BgColor menu, you will also set all the selected graphics'
foreground or background colors.  The ``on'' bits in the bitmaps for
dashed lines and fill patterns appear in the foreground color while
the ``off'' bits appear in the background color.  A black and white
printer will print a halftoned shade of gray for any color other than
black or white.  The brush, pattern, and font indicators all reflect
the current colors.
.PP
The
.B Align
menu contains commands to align graphics with other graphics.  The
first graphic selected stays fixed while the other graphics move in
the order they were selected according to the type of alignment
chosen.  The last Align command, \fBAlign to Grid\fB, aligns a key
point on each selected graphic to the nearest point on idraw's grid
(see below).
.PP
The
.B View
menu contains the following commands:
.TP 15
.B New View
Create a duplicate idraw window containing a second view of the
current drawing.  The second view may be panned, zoomed, and edited
independently of the first.  Any number of additional views may be
made in this manner.  Changes made to a drawing through one view
appear synchronously in all other views of the same drawing.  You may
also view another drawing in any idraw window via the Open command.
.TP
.B Close View
Close the current idraw window.  Closing the last idraw window is
equivalent to issuing a Quit command.
.TP
.B Normal Size
Set the magnification to unity so the drawing appears at actual size.
.TP
.B Reduce to Fit
Reduce the magnification until the drawing fits entirely within the
view.
.TP
.B Center Page
Center the view over the center of the 8.5 by 11 inch page.
.TP
.B Orientation
Toggle the drawing's orientation.  If the editor was formerly showing
a portrait view of the drawing, it will now show a landscape view of
the drawing and vice versa.
.TP
.B Grid on/off
Toggle idraw's grid on or off.  When the grid is on, idraw draws a
grid of equally spaced points behind the drawing.
.TP
.B Grid Spacing...
Change the grid spacing by specifying one or two values in the units
desired (pixels, points, centimeters, or inches).  If two values are
given (separated by a space), the first specifies the horizontal
spacing and second the vertical spacing.  One value will specify equal
horizontal and vertical spacing.
.TP
.B Gravity on/off
Toggle gravity on or off.  Gravity constrains tool operation to the
grid, whether or not the grid is visible.
.SH "X DEFAULTS"
You can customize the number of undoable changes and the font, brush,
pattern, or color menus by setting resources in your X defaults
database.  Each string of the form ``idraw.resource:definition'' sets
a resource.  For example, to customize any of the paint menus, set a
resource given by the concatenation of the menu's name and the entry's
number (e.g., ``idraw.pattern8'') for each entry that you want to
override.  All menus use the number 1 for the first entry.

You must set resources only for the entries that you want to override,
not all of them.  If you want to add entries to the menus, simply set
resources for them.  However, don't skip any numbers after the end of
the menu, because the menu will end at the first undefined resource.
To shorten a menu instead of extending it, specify a blank string as
the resource for the entry following the last.
.PP
Idraw understands the following resources:
.TP 15
.B history
Set the maximum number of undoable changes (20 by default).
.TP
.B initialfont
Specify the font that will be active on startup.  Supply a number that
identifies the font by its position in the Font menu starting from 1
for the first entry.
.TP
.BI font i
Define a custom font to use for the \fIi\fPth entry in the Font menu.
Give three strings separated by whitespace.  The first string defines
the font's name, the second string the corresponding print font, and
the third string the print size.  For example, ``idraw.font3:8x13bold
Courier-Bold 13'' defines the third font entry.
.TP
.B initialbrush
Specify the brush that will be active on startup.  Give a number
that identifies the brush by its position in the Brush menu starting
from 1 for the first entry.
.TP
.BI brush i
Define a custom brush to use for the
.IR i th
entry in the Brush menu.  The definition requires two numbers: a
16-bit hexadecimal number to define the brush's line style (each 1 bit
draws a dash and each 0 bit produces a gap), and a decimal integer to
define the brush's width in pixels.  For example, ``idraw.brush2:ffff
1'' defines a single pixel wide solid line. If the definition
specifies only the string ``none'', then it defines the nonexistent
brush.
.TP
.B initialpattern
Specify the pattern that will be active on startup.  Give a number
that identifies the pattern by its position in the Pattern menu
starting from 1 for the first entry.
.TP
.BI pattern i
Define a custom pattern to use for the
.IR i th
entry in the Pattern menu.  You can specify the pattern from a 16x16
bitmap, a 8x8 bitmap, a 4x4 bitmap, a grayscale number, or the string
``none''.  You specify the 16x16 bitmap with sixteen 16-bit
hexadecimal numbers, the 8x8 bitmap with eight 8-bit hexadecimal
numbers, the 4x4 bitmap with a single 16-bit hexadecimal number, and
the grayscale number with a single floating point number.  The
floating point number must contain a period to distinguish itself from
the single hexadecimal number, and it must lie between 0.0 and 1.0,
where 0.0 corresponds to a solid pattern and 1.0 to a clear pattern.
On the printer, the bitmap patterns appear as bitmaps, the grayscale
patterns appear as halftoned shades, and the ``none'' patterns never
obscure any underlying graphics.  For example, ``idraw.pattern8:8421''
defines a diagonally hatched pattern.
.TP
.B initialfgcolor
Specify the foreground color that will be active on startup.
Give a number that identifies the color by its position in the
FgColor menu starting from 1 for the first entry.
.TP
.BI fgcolor i
Define a custom color to use for the
.IR i th
entry in the FgColor menu.  Give a string defining the name of the
color and optionally three decimal numbers between 0 and 65535
following the name to define the red, green, and blue components of
the color's intensity.  The intensities override the name; that is,
idraw will look the name up in a window system database of common
colors only if you omit the intensities.  You can define shades of
gray by using equal proportions of each primary color.  For example,
``idraw.fgcolor8:Indigo 48896 0 65280'' defines a color that is a
mixture of red and blue.
.TP
.B initialbgcolor
Specify the background color that will be active on startup.
Give a number that identifies the color by its position in the
BgColor menu starting from 1 for the first entry.
.TP
.BI bgcolor i
Define a custom color to use for the
.IR i th
entry in the BgColor menu.  The same rules apply to background colors
as to foreground colors.
