<H2><CENTER>What is Etchelon TRACER?</CENTER></H2>
<P>Etchelon TRACER provides a useful tool for Quicktime development
for animated movies. It uses vector graphic morphing to develop
animated movies quickly for multimedia applications. Special effects
and animation can also be applied to existing Quicktime movies.</P>
<P>Speed of development is Etchelon TRACER's main benefit.</P>
<P>Clean line drawings can be traced from an existing PICT image to
allow rapid development of high quality vector graphics. Etchelon
TRACER will morph from any TRACER-frame-of-vector-graphics (hereafter
known as a "frame") to any other to provide animation, morphing or
special effects.</P>
<H3><CENTER>Features</CENTER></H3>
<UL>
<LI>Animation in-fill between key frames.
<LI>Morph animation from a frame to any other frame
<LI>Rapid development of vector graphics from bit mapped images.
<LI>Ability to experiment with outline animations.
<LI>Build up layers of animation to develop sophisticated
multi-object movies.
<LI>Easy-to-use drag-and-drop frame-copying and animation
sequencing.
<LI>Morphing Text.
<LI>Anti-aliased reduced sized output.
<LI>"Morph to any frame" using the frame navigator (side bar)
</UL>
<P>Etchelon TRACER is fully functional shareware and while not
save-disabled has some output restrictions until registered.</P>
<P>Etchelon TRACER outputs multiple files in PICT format. Separate
programs (see below) allow the development of Quicktime Animations
and overlays onto existing Quicktime movies.</P>
<H3><CENTER>Terminology</CENTER></H3>
<P>Etchelon TRACER has 35 frames (key frames). Between each frame
TRACER can in-between 999 frames of animation. Each frame are made up
of points drawn together to form "vectors". A vector graphic can
contain straight lines or curves of a single colour. There is a limit
of 600 points in a frame. Each frame can have a separate "Trace
image". Vectors can be colour-filled to form a "filled shape". All
frames use the same main window. The main window title gives the
frame number.</P>

<H2><CENTER>Drawing</CENTER></H2>
<H3><CENTER>Modes</CENTER></H3>
<P> </P>
<P>Etchelon TRACER works in several Drawing Modes</P>
<UL>
<LI>Selection mode - cursor is the usual arrow.
<LI><B>Pen Mode </B>- cursor is a pen - click to put pen down or
form a point, double click (or SPACE) for pen up. Enter and exit
by Menu/Draw/Pen, I, Command Palette icon or ESC key.
<LI><B>Edit mode</B> - cursor is a cross, allows vector resizing,
repositioning, colour change, shape fill, cut and paste. Enter by
selecting a vector point. Exit by selecting blank space or ESC
key.
<LI><B>Point Edit Mode</B> - cursor is diagonal cross, allow point
position changes, line-to-arc changes, colour changes and shape
fill. Enter Edit mode from vector selected mode by clicking a
point. Exit by clicking blank space or ESC key
</UL>
<P>Information messages and the different cursor types will guide you
through the Drawing Modes.</P>
<H3><CENTER>Creating Vectors</CENTER></H3>
<P>Selecting the pen command from either the menu, I or by clicking
the pen icon on the Command Palette, starts Pen Mode and allows
vector line drawing. The Command Palette will change to allow
changing the colour and pen thickness.</P>
<P>Mouse clicks provide break points on the vector. The Arc (R)
command bends the current vector line. DELETE removes the last line.
The SPACE bar or a double-click ends a vector (pen up) and the next
mouse click is pen down and so on, until the pen mode is cancelled
(by I, clicking on the Command Palette or ESC).</P>
<P>Vectors can be "traced" over a base image - in fact, this feature
will save a great deal of time and aid in producing good quality art
work.</P>
<P> </P>
<H3><CENTER>Resizing, Repositioning and Rotation</CENTER></H3>
<P>With the pointer cursor, vectors can be selected, moved, rotated
or re-sized. Selected vectors can also be cut, copied or moved within
the frame structure (i.e. moved to back or front).</P>
<P>To select a vector, either:</P>
<UL>
<LI>click on a vector point, or
<LI>encompass an area containing a vector by click and drag.
</UL>
<P>If you encompass all vectors in the frame, this causes all vectors
to be selected (Same as A) and allows all vectors to be resized,
repositioned and rotated.</P>
<P>The cursor will change when it positioned over any control point.
The cursor will change to a diagonal cross when it is positioned over
a vector point. When a vector is selected vector points are
highlighted and a boundary box around the vector is displayed. The
vector can be cut, copied, moved to back or front. Holding down the
mouse key when the cursor is on any corner of the boundary box (the
cursor will be a bold cross) allows the vector to be re-sized.
Holding down the mouse key when the cursor is on the boundary box
edges allows the vector to be repositioned - the cursor will be a
hand. Holding down the mouse key when the cursor is on the
highlighted bottom circle on the boundary edge allows the vector to
be rotated - again the cursor will change, this time to a rotate
symbol.</P>
<P>While the vector is selected its colour can be changed or it can
be switched to a filled shape or back to an outline shape (U) - also
avaiable from the Command Palette.</P>
<P> </P>
<H3><CENTER>Zoom</CENTER></H3>
<P>Zoom can be selected from the Command Palette or menu (further
zoom is possible from the Command Palette), or return back to
standard size. The Command Palette Direction icon moves the frame in
the selected direction. (Filled Shape Display is automatically
disabled during zoom moves but it can be re-enable once you have
scrolled to the area of interest).</P>
<P><CENTER> </CENTER></P>
<H3><CENTER>Vector Amendment</CENTER></H3>
<P>Having selected a vector, clicking on a vector point allows
editing of the point positions. The cursor will change to reflect
Edit mode. The vector can be modified at that point. Edit mode will
continue if points (on any vector) are selected (and changed). Also
while in this mode, the line<B> </B>drawn <B>before</B> the selected
point can be changed to an arc (R) or the whole vector's colour can
be changed or the vector can be changed to/from a filled polygon (U)
.</P>
<P>Edit mode is entered after resizing, repositioning or rotation, to
perform another resizing, repositioning or rotation action, click on
empty space and re-select the vector.</P>
<P> </P>
<H3><CENTER>The Command Palette</CENTER></H3>
<P>The Command Palette provides additional drawing tools:</P>
<UL>
<LI>Text Shapes
<LI>Outline/Filled Squares
<LI>Outline/Filled Circles
<LI>Outline/Filled Regular polygons
<LI>Outline/Filled Regular Star Shapes
<LI>The ability to change the number of points within a polygon or
star up to 20 sided Polygons or 20 pointed stars.
</UL>
<P> </P>
<H2><CENTER>Sequencing</CENTER></H2>
<P>Sequencing is performed by dragging and dropping frames within the
Morph Sequence Control window (Morph/Sequence Menu Option (E). To
start a sequence of morphs from say, frame 1 to frame 5 to frame 2,
hold the mouse down over frame 1, drag it to frame 5 and release.
Pick up frame 2 and drag it to frame 2. Control language statements
will appear in the text field on the right hand side of the window.
The sequence is played by the Morph/Run Sequence menu option (G) or
Robot icon on the Command Palette.</P>
<P>The number of transitions per morph is set by the scroll bar on
the right. Adjust the scroll bar before performing the drag and drop
otherwise, edit the YYY figure in the @tNN/YYY command.</P>
<P>For most circumstances this is all you'll need. For those who need
more precise control, there is a simple set of control instructions.
A sequence control instruction statement looks like this:</P>
<P><B>@m01/05</B></P>
<P>which means morph from frame 1 to frame 5.</P>
<P>The sequence instructions exist in blocks of 255 characters and
have the same general format:</P>
<P><B>@<letter><parameter>{/<parameter}</B></P>
<P>and are separated by a colon ":" or end of block. The @ character
is required before all commands. If no @ is found the rest of the
line in the block is ignored.</P>
<P>The list of commands are as follows:</P>

</OL>
<H3> </H3>
<H2><CENTER>Other Programs</CENTER></H2>
<H3><CENTER>Movie to PICT</CENTER></H3>
<P>To work upon existing Quicktime Movies, use Movie-to-PICT to
generate the Quicktime Movie as a series of PICT files. Use selected
images as "key frames" within Etchelon TRACER and build up animation
and morph sequeunces with the number of transition steps to match the
numbered files generated by Movie-to-PICT. Backgrounder and
PICTs-to-Movie will rebuild the quicktime movie with your animation
superimposed. Note that any sound track is lost and would have to be
re-dubbed by another software utility. (WARNING: This program is
incompatible with MacLinkPlus and Mac Easy Open extensions, they need
to be disabled while this program is required)</P>
<P> </P>
<H3><CENTER>Backgrounder</CENTER></H3>
<P>Etchelon TRACER produces Line drawings and simple filled-shape
animation. To provide more sophisticated animations, you can use
"Backgrounder" which adds a Background picture. Instructions are
provided in the program. The background does not have to be static, a
moving background can also be added (for example, the files created
by Movie to PICT). Indeed the output of backgrounder can be later
used as its own input to allow multiple layers of animation.</P>
<P>Backgrounder relies upon sequence numbers for both moving
background images and foreground images. The sequence numbers do not
have to be aligned or even the same quantity. Experiment and see.

<P>PICTs to Movie is a Freeware package to convert the output of
Etchelon TRACER to a Quicktime movie. It is available as a separate
product from the Info-Mac Archives and thanks go to David Rees to
allow it to be distributed with Etchelon TRACER. Comments about this
program should be addressed to him. Despite what it says in the
program itself, a more up-to-date address for David Rees is:
"drees@altorsys.com".</P>

<H2><CENTER>System Requirements</CENTER></H2>
<P> </P>
<P>Etchelon TRACER will run on both 68nnn and PowerPC systems. It has
been tested on MacOS 7.5.5, System 8.0 and System 8.1 although it
should also run on earlier versions of System 7. It requires at least
1.5Mb of RAM. Etchelon TRACER requires a colour Macintosh (probably
with a 13 inch monitor screen). TRACER produces lots of output files,
it is recommended to ruthlessly delete these output files once you
have finalised your Quicktime movie. If limitations within the
software are stopping you, let me know and I'll see what I can do!
</P>
<P>Bug reports are welcome. Please send them to etchelon@kagi.com.
</P>
<P>Other programs you will need are: Apple's SimpleTEXT to view
output from TRACER. To view and edit Quicktime Movies, you will
require Apple Quicktime Movie Player. A paint program such as that
provided by Apple-Works is also useful.</P>
<P>TRACER's PICT output can also be used build up animated GIFs for
web page development using Freeware tools such as GIFBuilder.</P>
