<h1>4 General Concepts</h1>
<p>
After you start up Ipe, you will see a window with a large gray area
containing a light yellow rectangle. This area, the <em>canvas</em>, is
the drawing area where you will create your figures. The light yellow
rectangle is your "sheet of paper", the first page of your document.
(While Ipe doesn't stop you from drawing outside the paper, such
documents generally do not print very well.)
<p>At the top of the window, above the canvas, you find the following toolbars:
<ul><li>File tools (new document, load, save, as well as cut and
paste),
<li>Resolution tools (screen resolution selection),
<li>Page tools (page and view number),
<li>Color tools (stroke and fill color),
<li>Line tools (line width, dash style, arrow shape and size),
<li>Mark and text size settings,
<li>Snap tools (snapping modes, grid size and angular resolution),
<li>Mode tools (mode selection).
</ul>
<a name="id1">
On</A> the left hand side of the canvas you find a list of the
<em>layers</em> of the current page.
<p>All user interface elements have tool tips--if you move the mouse
over them and wait a few seconds, a short explanation will appear.
For a longer explanation, use the <em>"What's This?"</em> button on
the file tools toolbar (it looks like a cursor pointer with a question
mark). Press the button, then click with the mouse on any part of the
user interface for a short explanation.
<p>The mode toolbar allows you to set the current <em>Ipe mode</em>.
Roughly speaking, the mode determines what the left mouse button will
do when you click it in the figure. The leftmost five buttons select
modes for selecting and transforming objects, the remaining buttons
select modes for creating new objects.
<p>Holding the Control key and pressing the right mouse button, by the
way, pops up the object attribute menu in any mode.
<p>In this chapter we will discuss the general concepts of Ipe.
Understanding these properly will be essential if you want to get the
most out of Ipe.
