new expressions. You can type stuff here, and <span 
class="phvr7t-x-x-80">nip2 </span>will
make a new row for each item you enter. Try typing <span 
class="phvr7t-x-x-80">2 +</span>
<span 
class="phvr7t-x-x-80">2 </span>and pressing Return. The syntax is (almost, with a
few small differences) the same as the C programming
language. See <span 
class="cmsy-10">ยง</span><a 
href="nipguidese27.html#x38-630006.6">6.6<!--tex4ht:ref: sec:operators --></a> for a list of the differences. Try
multiplying the joined images by a small amount (eg. type
something like <span 
class="phvr7t-x-x-80">A9 * 1.2 </span>and press Return). Normally <span 
class="phvr7t-x-x-80">nip2 </span>will
pick names for new objects for you (like <span 
class="phvr7t-x-x-80">A1</span>), but you
can set a name yourself if you like. Try entering <span 
class="phvr7t-x-x-80">fred =</span>
<span 
class="phvr7t-x-x-80">12</span>.
<!--l. 172--><p class="indent" >  Click the down button once on your brightened image
and left-click on the area just below the thumbnail. You
should see the stuff you typed to make that row. You
can edit it to be anything else, press Return and <span 
class="phvr7t-x-x-80">nip2</span>
will recalculate. Try going back to your original image
(the one you loaded from a file), open an image view
window, and try dragging one of the regions. You can
change any of the sliders in the rotate or the join rows as
well.
<!--l. 179--><p class="indent" >  Right-click on a thumbnail for a useful menu. Use <span 
class="phvr7t-x-x-80">Save</span>
<span 
class="phvr7t-x-x-80">As </span>to save an image to a file. Use <span 
class="phvr7t-x-x-80">Replace From File </span>to change
the image in a row (and recalculate the rest of your
workspace, very handy). Use <span 
class="phvr7t-x-x-80">Header </span>to view an image&#8217;s
metadata.
<!--l. 184--><p class="indent" >  You can also edit the insides of objects. Click the down
button next to one of your regions until the <span 
class="phvr7t-x-x-80">width </span>and
<span 
class="phvr7t-x-x-80">height </span>rows appear, click on <span 
class="phvr7t-x-x-80">width </span>and type <span 
class="phvr7t-x-x-80">height * 2</span>.
Now open the image window the region is defined on
and try to resize it: you&#8217;ll find that the width of the
region is fixed, but that if you change the height, the
width changes with it. This is a very general property of
classes in <span 
class="phvr7t-x-x-80">nip2</span>: you can use it to join objects together in
complex ways, and to modify the behaviour of interactive
objects.
<!--l. 192--><p class="indent" >  Right click on a column title bar to get a useful menu.
Click on <span 
class="phvr7t-x-x-80">File </span>/ <span 
class="phvr7t-x-x-80">New </span>/ <span 
class="phvr7t-x-x-80">Column </span>make another column (handy for
organising a workspace). If you drag from an image
thumbnail on to the workspace background, <span 
class="phvr7t-x-x-80">nip2 </span>will make a
new column for you. You can drop thumbnails on to other
thumbnails to make links.
<!--l. 198--><p class="indent" >  There&#8217;s a useful right-click menu on the tab name.
Duplicating tabs is a very easy way to try something out:
make a copy of your tab, try changing something, if it
doesn&#8217;t work out, just delete your new tab and go back to
where you were. You can drag tabs between workspaces,
and you can drag a tab to the desktop to make a new
workspace. You can make references between tabs with thetab name and a dot, for example <span 
class="phvr7t-x-x-80">tab1.A1</span>. You can save
 columns, tabs or workspaces to workspace files, then merge
 them back into a colum, as part of a tab, or as a new
 tab.
 <!--l. 207--><p class="indent" >    If <span 
class="phvr7t-x-x-80">nip2 </span>falls over (I do hope it doesn&#8217;t), you can usually
 get your work back by restarting <span 
class="phvr7t-x-x-80">nip2 </span>and clicking on <span 
class="phvr7t-x-x-80">File </span>/
 <span 
class="phvr7t-x-x-80">Search for Workspace Backups</span>. There are a lot of preferences
 (perhaps too many), see Appendix&#x00A0;<a 
href="nipguideap1.html#x48-89000A">A<!--tex4ht:ref: sec:config --></a>.
 <!--l. 212--><p class="indent" >    There is a lot of stuff in the <span 
class="phvr7t-x-x-80">Toolkits </span>menus, but they do
 almost all have tooltips. If you let your mouse hover over a
 menu item for a moment you should get some helpful text.
 The toolkit menu is organised by object type. If you want to
 do something to a matrix, look in the <span 
class="phvr7t-x-x-80">Toolkits </span>/ <span 
class="phvr7t-x-x-80">Matrix </span>menu.
 The exception is <span 
class="phvr7t-x-x-80">Toolkits </span>/ <span 
class="phvr7t-x-x-80">Tasks </span>which repeats many of the
 regular toolkit items, but groups them by typical tasks
 instead.
 <!--l. 220--><p class="indent" >    Operations can work on groups as well as on single
 images, so you can batch things up. If you save a group of
 images, <span 
class="phvr7t-x-x-80">nip2 </span>will number each image sequentially for you.
 You can use <span 
class="phvr7t-x-x-80">Edit </span>/ <span 
class="phvr7t-x-x-80">Duplicate </span>to make copies of objects. If you
 select lots of objects and duplicate them, <span 
class="phvr7t-x-x-80">nip2 </span>will (fairly
 intelligently) rename everything for you so it all still
 works.
