New features (version 1.11)
===========================
This demo contains significant new features and is also StrongArm
compatible. The new features are documented here very briefly.
• PCA (Plug-in Compliant Application) compatible
• Save sprite in any number of colours
• Save canvas as GIF file including transparency option
• On canvas interactive rotation
• On canvas interactive scaling
• Auto masking of Draw and ArtWorks files
• Load, Render and manipulate TopModel files
• Crop canvas to window
• New Print option
• Improved redraw routines
• All vector format data now retained and any transformations are done
using the vectors to provide much better quality
• DPI - changes to the page units and the way this interacts with the
physical size of the canvas.
• Default Preferences option
• New Hot keys
• Loading of progressive JPEGs
PCA Compliant
=============
PCA is a protocol that enables applications to share data such that editing
is immediately reflected in all linked applications. For example Composition
can be used to edit a graphic frame in Ovation Pro without having to copy
the data.
This demo is PCA compliant. PCA tools will appear in the Select > Utils menu
if the tools have been loaded prior to opening the menu. Compatible tools
include !SPaint and !Processor. Ovation Pro version 2.36 onwards is also PCA
aware.
More information on PCA can be obtained from our web site in the Support
section at
http://www.stcoll.ac.uk/clares/
New Save options (Disabled)
===========================
Sprite save in various colour depths
GIF saving
ROTATION
========
On canvas rotation is now provided. The blue arrow in the toolbar can be
clicked on to change it to a Rotate arrow. In this mode selected objects can
be rotated by dragging them with Adjust. Rotation applies to all object types.
SCALING
=======
On canvas scaling is now provided. If the blue arrow icon in the Toolbar has
a large arrow together with a small one it is in Scale mode. Dragging on a
selected object with Adjust re-scales the object and re-draws the image to
the new scale.
Holding down Shift causes the image to retain its aspect ratio.
AUTO MASKING
============
When loading vector files (Draw, ArtWorks and TopModel) you can toggle the
icon between vector (Draw icon) and bit image (Sprite icon) objects. When
loading as bit image (we call it Vector-in-Sprite or V-i-S) you can also
choose to apply an auto mask which attempts to create a mask from the
background. With ArtWorks objects this can look a little odd due to the anti
aliasing.
Note: Due to the fact that you cannot save with this demo version the mask
will be lost when you rotate.
TopModel files
==============
Compo will now load and manipulate TopModel files as long as a copy of the
Gemini rendering engine has been seen. A copy of this is supplied on the
StrongArm sample CD. Just opening the Commercial.Sincronia directory is
sufficient. You can then load the files in the 3DScenes directory.
INFORMATION
===========
This is the demonstration version of Composition,
the bitmap image composition package from Clares Micro Supplies.
This Demo version of Compo may not be totally up to date with the full
release version but it is sufficient to whet your appetite for the full
version. Features missing from the demo are -
* All methods of saving your work have been removed.
* The OLE feature has been disabled
* Printing has been disabled
* The word 'DEMONSTRATION' is printed over your work and
cannot be removed. THIS ALSO SLOWS DOWN THE REDRAW SPEED OF THE SCREEN.
Hardware requirements
=====================
Compo requires an Acorn RiscPC with AT LEAST 8Mbytes of main memory. 2Mbytes
or more of VRAM is recommended. For serious use in creating A4 images, a
minimum of 16Mbytes of main memory is required and more is almost always
better! Clares can provide additional memory if required. Phone or visit our
web site for current prices.
http://www.stcoll.ac.uk/clares/
If you have a small machine, i.e 16Mb DRAM or less, you may find !Virtualis
from Clares useful. !Virtualis is a virtual memory manager for the Risc Pc
and works with most applications which use dynamic areas. See below for
details of using Compo with Virtualise.
Details on Virtualise can also be found on our web site.
Okay, last bit of advertising. If you are not using StrongArm you will
benefit from our SPEED! application. This speeds up your desktop and
applications by up to 600% and costs just £10. A demo can be downloaded from
our web site.
YOU ARE ADVISED TO COPY THIS DEMO ON TO YOUR HARD DRIVE.
About Composition
=================
Compo is an image composition program for the Acorn RiscPC range of
computers. With Compo, you combine bitmaps, Draw files, ArtWorks files,
TopModel files etc together on a canvas to make a composition. Draw files
and Artworks files can be loaded either as vectors, or converted into
bitmaps. Each bitmap remains completely independent from the rest. Links to
art packages (such as ProArtisan24 from Clares) allow you to edit any of the
images making up your composition and to see the results of your changes in
the composition immediately. In addition, the program allows a number of
effects such as colour correction, shadows, opacity, and tinting to be
applied independently to each image. Using these effects the images are
rendered to the canvas on the fly so the effects do not modify (and
therefore damage) the original image data.
Compo is useful not only to the graphics professional. It also allows those
users with less artistic ability to produce complex graphical effects such
as true shadows and photo montages at the click of a button. Because the
images themselves are not modified you can quickly change the effect
settings until the desired result is achieved.
If !Virtualis is present, the demo can use virtual memory. To switch it on,
go to the preferences window (accessed from the icon bar) and look at the
top option in the window. If this is ticked, virtual memory will be used if
the picture size exceeds the size of available RAM. You will need as much
hard disc space as the picture occupies.
Obviously, Compo contains far more features than can be described in this
file. If you have any questions about the program's capabilities, please
contact us and we will try to provide answers.
Example files
=============
Some completed JPEG files are included which illustrate the possibilities
available. Because of the size of Composition files, none are included with
this demo. The JPEG files may be viewed in Composition or ChangeFSI.

Tutorial (Adapted from the manual)
==================================
This section begins with a tutorial which then carries on into a series of
worked examples of some of the program's features. The example files used
are on the disc and should be copied to a 'Tutorials' directory on the hard
disc for fast access.
The basics
==========
1) Load Compo in the usual way, by double clicking on the program icon.
If possible, select a desktop of 800 x 600 x 16 million colours or 1024 x
768 x 32 thousand. Both of these desktops are useful. The latter gives you
considerably more room to manoeuvre, at the expense of some detail in the
colour graduations. We do not recommend using the program with the desktop
in fewer than 32 thousand colours. At a pinch, 256 greys is usually better
than 256 colours.
NOTE: Compo runs slightly faster with the desktop at 16 million colours as
it stores everything to this colour depth internally.
2) Select the the Compo icon bar icon to open a canvas of the default size
and colour.
NOTE: Clickin
