<h1>Object Attributes</h1>
Buttons to set various drawing parameters (called <i>attribute buttons</i>),
such as line width or color, are placed on the attribute panel.
Buttons to set global parameters such as the zoom scale or grid mode
are also placed on the attribute panel.
Current settings are displayed in each attribute button.
<p>
Settings in the attribute panel are applied when
<a href="drawing.html">creating new objects</a>.
It is also possible to modify attributes of existing objects
using <a href="editing.html#update">UPDATE</a>
or <a href="editing.html#edit">EDIT</a>.
<p>
The first three buttons do not control object attributes but are placed
here for convenience:

<p>
Normally, only the attribute buttons
which are significant to the selected mode
are placed on the attribute panel.
When it is not possible to display all the attribute buttons
at once, a scrollbar will be added to the attribute panel.
<p>
These settings may be changed by clicking those attribute buttons.
Each mouse button has the following function:
<p>
<dl>
<dt>
<img src="images/blueballdot.png" align=bottom alt="-">
Mouse button 1 (`Menu') </dt>
<dd>
Clicking an attribute button with mouse button 1 will
popup a panel to change setting of the attribute button,
and the user may select a new value by
clicking any button on the panel
(in the case of <i>grid mode</i> or <i>text font</i>, etc.)
or entering a new value from the keyboard
(in the case of <i>zoom scale</i> or <i>line width</i>, etc.)
<dt>
<img src="images/blueballdot.png" align=bottom alt="-">
Mouse button 2 (`Dec/Prev') </dt>
<dd>
If the attribute button contains a numeric value
(<i>zoom scale</i> or <i>line width</i>, for example),
clicking the attribute button with mouse button 2 will
decrease the value.
If the attribute button is of another type
(<i>grid mode</i> or <i>text font</i>, for example),
the selection will be chosen from the previous item in the list.
The list is considered circular.
<dt>
<img src="images/blueballdot.png" align=bottom alt="-">
Mouse button 3 (`Inc/Next') </dt>
<dd>
This mouse button is the reverse of mouse button 2.
If the attribute button contains a numeric value,
clicking the attribute button with mouse button 3 will
increase the value.
If the attribute button is of another type,
the selection will be chosen from the next item in the list.
The list is considered circular.
</dl>
<p>
In <a href="editing.html#update">UPDATE</a> mode,
a small toggle button appears in the upper-right corner of each attribute button.
This controls whether the particular attribute should be applied when using
the UPDATE mode.
Also, an <a href="editing.html#update-control">Update Control Button</a>
will be placed at the left of the attribute panel.
<p>

<p>
<dl>
<dt><img src="images/zoom-button.png" alt="">
<a name="zoom-scale">(ZOOM SCALE)</a>
<img src="images/zoom-panel.png" align=right alt="zoom panel">
<dd>Set the zoom scale of display on the canvas.
The zoom scale may be set in the range of 0.01 to 50.
On many systems, the display on the screen will be almost actual-size
when this is set to 1.
<p>
Clicking this button with mouse button 1 will popup a panel
to enter new value of zoom scale from keyboard.
Clicking this button with mouse button 2 or mouse button 3
will decrease or increase the zoom scale by a factor of 1.5 respectively
if the zoom is > 1, or
by 0.1 if zoom scale is less than 1.0 and 0.01 if the zoom is less than 0.1.
<p>
Zooming of the canvas may also be performed by
specifying the rectangle to be zoomed on the canvas (`area zoom').
To do this, specify the rectangle to be zoomed by
clicking mouse button 1 (`zoom area') while pressing CONTROL key
and specify one corner of the rectangle,
and then clicking mouse button 1 (`final point') again
at the opposite corner of the rectangle.
<p>
If you use a wheel mouse,
then rotating the wheel on the canvas while the
<b>Shift</b> key is pressed
will zoom/unzoom the canvas around the pointer
and rotating the wheel while the
<b>Control</b> key is
pressed will scroll (pan) the canvas up or down.
<p>
It is also possible to set zoom scale to 1
by clicking mouse button 3 (`unzoom') while pressing CONTROL key
on the canvas.
<p>
To force the area-zoom to zoom using integer values check the box
in the zoom popup panel that says <i>Integer zoom</i>.
<p>
To zoom the figure so that it just fills the canvas, press the
<i>Fit to canvas</i> button. <i>Integer zoom</i> is ignored
if the zoom needed to fit the figure on the canvas is less than 1.0.
<p>
See also <a href="panning.html#zooming">Zooming</a>.
<hr>
<p>
<dt><img src="images/depth-button.png" alt="">
<a name="depth">(DEPTH)</a>
<dd>Set the `<i>depth</i>' of objects.
<p>
The <i>Depth</i> is used to decide which object should be hidden
when objects overlap.
The object with larger <i>depth</i> will be hidden by
object with smaller <i>depth</i>.
<i>Depth</i> is an integer value of the range 0 to 999.
<p>
If objects with the same <i>depth</i> overlap,
it is unknown which object will be hidden,
and the display on the screen may be different from a printout or export.
<p>
Normally, all depths are displayed on the canvas, but the user may control
which depths are displayed and editable.
See the <a href="layers.html#depth_panel">Depth Panel</a> section.
<p>
If the depth of a compound object is changed with
<a href="editing.html#update">UPDATE</a>,
the relative depths of the objects contained will be maintained.
For example, consider a compound object containing three objects
at depths 3, 8 and 11 respectively.
If the depth of the compound is changed to 2, then the objects contained
will have depths of 2, 7 and 10 respectively.
<hr>
<p>
<dt><img src="images/grid-button.png" alt="">
<a name="grid-mode">(GRID MODE)</a>
<dd>Set the size of the grid displayed on the canvas.
If this is set to <i>None</i>, no grid will be displayed.
<p>
The size of the grid may be selected
from 1/8inch, 1/4inch, 1/2inch and 1inch
if <a href="miscellaneous.html#units">unit</a> is set to <i>Imperial (inches)</i>,
and from 2mm, 5mm, 10mm and 20mm
if unit is set to <i>Metric</i>.
<p>
This grid will not restrict positioning of objects.
If you want to set a restriction of positioning of objects,
use <a href="#point-position">POINT POSITION</a>.

The user-defined colors may be modified using
RGB (red/green/blue) or HSV (hue/saturation/value) sliders.
It is also possible to enter hexadecimal values
to indicate the intensity of red, green and blue (each value is 00 to FF)
into the fields under <i>Edit Pen</i> and <i>Edit Fill</i>.
<p>
If two or three of the buttons above the red, green and blue sliders are checked
(the figure shows the red and green locked),
those sliders will be `locked' together,
so that moving the <i>Lock</i> slider will move those sliders together.

<h2><a name="font-panel">Font Panel</a></h2>
The Font Panel is used to select the font to draw text,
and it will popup when the
<a href="#text-font">TEXT FONT</a> button is clicked.
Only the font name may be selected here;
the size of the font must be set using <a href="#text-size">TEXT SIZE</a>.
<p>
There are two Font Panels;
one for PostScript fonts and one for LaTeX fonts.
<p>
<blockquote>
<img src="images/text-font-panel.png" alt="[Font Panel - PostScript]">
<p>
<img src="images/text-font-panel-latex.png" alt="[Font Panel - LaTeX]">
</blockquote>
<p>
Clicking a font button
(the labels of the buttons are drawn using the font)
will select that font.
Clicking the <i>Use LaTeX Fonts</i> button will
switch to the panel for LaTeX fonts,
and clicking <i>Use PostScript Fonts</i> button will
switch to the panel for PostScript fonts.
<p>
It is not guaranteed that all fonts in the panel of PostScript fonts
are available on all PostScript printers.
Also, different fonts may be used on the screen.
This is dependent on which fonts the X server has.
But at least
<i>Times-Roman</i>, <i>Times-Italic</i>, <i>Times-Bold</i>, <i>Times-BoldItalic</i>,
<i>Courier</i>, <i>Courier-Oblique</i>, <i>Courier-Bold</i>, <i>Courier-BoldOblique</i>,
<i>Helvetica</i>, <i>Helvetica-Oblique</i>, <i>Helvetica-Bold</i> and <i>Helvetica-BoldOblique</i>
will be available in most environments.
<p>
<img src="images/pict-i18n.png" alt="[I18N]">
In <a href="i18n.html">international-<b>xfig</b></a>,
"<i>Times-Roman</i>" and "<i>Times-Bold</i>" will be replaced with
<blockquote>
<img src="images/font-menu-japanese.png"
alt="Times-Roman + Mincho and Times-Bold + Gothic">
</blockquote>
in the Japanese environment, and
<blockquote>
<img src="images/font-menu-korean.png"
alt="Times-Roman + Mincho and Times-Bold + Gothic">
</blockquote>
in the Korean environment.
It is possible to put Japanese or Korean in text
when these fonts are selected.
