-
- <P>Etchelon TRACER provides a useful tool for Quicktime development
- for animated movies. It uses VITMA (Vector graphics, Image Tracing
- Morphing Animation) to develop animated movies quickly for multimedia
- applications. Morphing, special effects and animation can also be
- applied to existing Quicktime movies.</P>
-
- <P>Speed of development is TRACER's main benefit.</P>
-
- <P>Clean line drawings can be traced from a PICT image to allow rapid
- development of high quality vector graphics. 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>

-
- <P>Etchelon TRACER is full featured shareware and is not
- save-disabled.</P>
-
- <P>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>TRACER has 35 frames (key frames). Each frame are made up of
- points drawn together to form "contours". Contours 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>
-
- <P>A contour is a vector graphic containing 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" - the image is only used for
- tracing.</P>

-
- <P> </P>
-
- <P>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, I or palette controls
-
- <LI><B>Edit mode</B> - cursor is a cross, allows contour resizing,
- repositioning, colour change, shape fill, cut and paste. Enter by
- selecting a contour point. Exit by selecting blank space.
-
- <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 contour selected mode by clicking a
- point. Exit by clicking blank space.
- </UL>
-
- <P>Information messages and the different cursor will guide you
- through the Drawing Modes.</P>
-
- <H3><CENTER>Creating Contours</CENTER></H3>
-
- <P>Selecting the pen command from either the menu, I or by clicking
- the pen icon on the palette, starts Pen Mode and allows contour line
- drawing. The palette will change to show the pen X, Y position on
- screen and also allows changing the colour and pen thickness.</P>
-
- <P>Mouse clicks provide break points on the contour. The Arc (R)
- command bends the current contour line. DELETE removes the last line.
- The SPACE bar or a double-click ends a contour (pen up) and the next
- mouse click is pen down and so on, until the pen mode is cancelled
- (by I or clicking on the palette).</P>
-
- <P>Contours 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, contours can be selected, moved, rotated
- or re-sized. Selected contours can also be cut, copied or moved
- within the frame structure (i.e. moved to back or front).</P>
-
- <P>To select a contour, either:</P>
-
- <UL>
- <LI>click on a contour point, or
-
- <LI>encompass an area containing a contour by click and drag.
- </UL>
-
- <P>If you encompass all contours in the frame, this causes all
- contours to be selected (Same as A) and allows all contours 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 contour point. When a contour is selected contour points are
- highlighted and a boundary box around the contour is displayed. The
- contour 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 contour to be re-sized.
- Holding down the mouse key when the cursor is on the boundary box
- edges allows the contour 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 contour to
- be rotated - again the cursor will change, this time to a rotate
- symbol.</P>
-
- <P>While the contour is selected its colour can be changed (U) or it
- can be switched to a filled shape (Y) or back to an outline shape.
- </P>
-
- <P> </P>
-
- <H3><CENTER>Zoom</CENTER></H3>
-
- <P>Zoom can be selected from the palette or menu - further zoom is
- possible, or return back to standard size. Click on the palette
- direction icon will move 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>Contour Changes</CENTER></H3>
-
- <P>Having selected a contour, clicking on a contour point allows
- editing of the point positions. The cursor will change to reflect
- Edit mode. The contour can be modified at that point. Edit mode will
- continue if points (on any contour) 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 contour's colour can
- be changed (U) or the contour can be changed to/from a filled
- polygon (Y).</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 contour.</P>
-
- <P> </P>
-
- <H3><CENTER>Other Controls</CENTER></H3>
-
- <P>Other controls on the palette can change the frame to the next
- frame or previous frame or Morph forward. The Robot icon starts an
- animation sequence. (Sequencing is described below).</P>
-
- <P>Hold the SHIFT key down, and further options are available:</P>
-
- <UL>
- <LI>Display Circle/Polygon Drawing Tools (as per menu option).
- Described further below.
-
- <LI>Go to first frame.
-

-
- <H2><CENTER>Sequencing</CENTER></H2>
-
- <P>Sequencing is performed 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 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>@m01/05</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>@<letter><parameter>{/<parameter}</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>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 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.</P>

- <H3><CENTER>Backgrounder</CENTER></H3>
-
- <P>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
- 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 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>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. It requires at
- least 1.5Mb of RAM. 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. It 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>
