WelcometoGIFAnimator
Welcome to Ulead GIF Animator, the industry standard for GIF animation. From its drag-and-
drop simplicity to its numerous customization options, GIF Animator takes all the hard work
out of building web-animations while giving you room to flex your creative muscles. Its built-
in, top-notch optimization engine makes your animation compact and web-ready in seconds
while retaining its overall quality. And, when you’re ready to embed them in your web pages,
GIF Animator generates all the necessary HTML code for you.
The Animation Wizard walks you through the creative process in three quick and easy steps. When you’re
finished, run the Optimization Wizard to make your animation as compact as possible for faster download
times on the Internet.
GIF Animator’s intuitive layout makes working with
animations a snap. The Layer pane lists each image
layer in the animation, either as thumbnails or as a
list, and the Workspace allows you to adjust and
position image layers. You can also work with multiple
image layers simultaneously. Its mode structure allows
you to switch between composition, editing, optimiza-
tion and preview tasks quickly and easily.

5
GIF Animator, while primarily a post-production tool, does give you the capability to work on
image layers directly within the program. You can perform minor touch-ups and edits right on
an image layer, rather than having to open it in an outside image editor.
Edit mode lets you add, remove and adjust the pixels in each image layer. It can help you clean up the
residue from bad scans, or adjust the color and lines that you want to emphasize on an object. The Edit
toolbar also contains tools for manipulating your image layers. The Crop tool pares away excess portions
of an image and the Resample tool resizes your animation, just to name a couple.
Additionally, GIF Animator supports APS 32-bit plug-ins: any plug-in that you can use in PhotoImpact,
Photoshop and Paint Shop Pro can now be used directly within GIF Animator for enhancing image layers.
GIF Animator comes with more than 30 custom video filters and effects, borrowed from Ulead’s award-
winning MediaStudio Pro, and is also capable of both importing and exporting video files.

What’s new in this version*
This version of GIF Animator contains some significant improvements and additions to the last
version, including:
New work modes – An improved user
interface lets you do your layout, edits and
touch-ups all directly within the main pro-
gram window. The work modes are: Com-
pose, Edit, Optimize, and Preview. Intuitively
placed tabs let you switch modes instantly
while you create your animations.
Improved optimization – A new algorithm
makes your animated GIF files even smaller
than before, and easy-to-access optimization
presets in Optimize mode make optimizing
your files a snap. Once you create and save a
preset, you no longer have to concern
yourself will all the different optimization
options. Simply click the Optimize button and
GIF Animator does the rest.
Batch Process your web site – If you have
an entire web site of animated GIF files that
you want to optimize, then GIF Animator is
the solution for you. With Batch Process, you
can run every animated GIF file through the
GIF Animator optimization engine and see the
results in seconds. Smaller files mean faster
loading web sites.
More Special F/X – Added special effects
expand your creative potential while design-
ing animations. The new effects include
Neon, Gradient, and Marquee banner text,
among others.

Customizing how you work
With the Preferences dialog box, GIF Animator lets you customize how you work. For
example, you can define how images are converted from high color formats down to the basic
GIF color palette of 256 colors, append a personalized comment to each animation, and set up
the number of undo levels available while working. The Preferences dialog box can be opened
by clicking the File: Preferences menu command.
Important Preferences options:
•On the General tab, create a custom color
index for the Global Palette - you can build
this palette based on the first imported
image, or use a pre-defined palette of
‘browser-safe’ colors. You can also use a
previously saved color palette file. Gener-
ally speaking, the first option (Use the
palette of the first layer image) offers
the most flexibility.
•Because all palettes, including the Global
Palette and all Local Palettes, can only
contain a maximum of 256 colors, you
should select the Automatically expand
Global Palette option on the General tab
in order to fill the Global Palette with as
many colors as possible from imported
images. This frees up space in each of the
Local Palettes for storing colors specific to
image layers, making the GIF smaller.
• On the Image Layer tab, select the Show
Preview Image dialog box option to
manually build the color palette of each
image layer as it’s imported. If you want
GIF Animator to do this automatically,
deselect this option and then set the default
Palette conversion options for each
imported image layer.

10
Creating a new animation
Getting started with GIF Animator is a snap. All animations consist of a series of ‘stacked’
images, with each image being a single ‘frame’ in the animation. You can build frames (called
layers in GIF Animator) by inserting individual images manually or by inserting portions of
digitized videos. You can also insert the contents of an entire folder or a range of selected files.
To create a new animation:
1 Click the Layer: Add Images menu
command or the Add Images button on
the Standard toolbar. The Add Images
dialog box opens.
2 Browse for the images you want to add
and select them.
3 Click OK. The images are added in
alphanumerical order to the Layer pane.
Tip:Youcan also add imagestoGIF Animator
bydragging them from the Windows Explorer
anddroppingthemdirectly into the program.
To import video frames:
1 Click the Layer: Add Video menu
command or the Add Video button on the
Standard toolbar. The Add Video dialog
box opens.
2 Browse for the video file from which you
want to extract a sequence.
3 In the Add Video Dialog box, click the
Duration button and then use the Mark-
in and Mark-out buttons to select the
sequence. Click OK when you’re done to
close the dialog box.
4 Click OK to insert the sequence.

11
Working with the Layer pane
Understanding how to work with image layers (also called frames or cels) in the Layer pane, is
the key to understanding how animations are built in GIF Animator. Once you comprehend the
basics of image layers, everything else is easy.
Image Layer Modes:
You can set the Layer Mode through the
View: Layer Pane - Mode submenu.
•List - Displays image layers as a list in the
Layer pane. Each image layer’s default
name is based on its original file name (if it
was inserted via the Clipboard, then it is
assigned a default name).
•Thumbnail - Displays each image layer as
a thumbnail image. All thumbnails are the
same size (sizes can be selected from the
View: Thumbnail Size- Size submenu).
•Filmstrip - Displays the layers as thumb-
nail images, each one sized in relation to
the others in the animation to show how
they correspond with one another.
To move image layers in the Layer pane:
•Select the layer you want to move and then
click either the Move up or Move down
buttons on the Standard toolbar.
Tip: Selectmultiplelayers using either theCtrlor
Shiftkeys while clicking the mouse button.
To use the context menu:
•Right-click over any layer in the Layer
pane to get the pop-up context menu of
common layer-editing commands.

12
Editing image layers
When building animations, you’ll often find that the work you did in your image editor to
prepare the images was not quite right - perhaps the colors didn’t quite convert from high
color to 256-color as well as you had hoped and visual residue was introduced into the layers,
or maybe the frames are too large. Whatever the reason, GIF Animator provides you with
simple tools for performing basic edits directly to your image layers within the program rather
than having to open them in an outside image editor.
Duplicating image layers
A useful tool for creating moving sprites from a single, still image is Duplicate. This allows
you to import a small, sprite-like image and place it over a larger background image. Using the
Duplicate command is one method of taking a single image and moving it across a larger
background. You can also using the Layer: Moving Sprite menu command to achieve similar
results with an animation rather than a single image
To duplicate image layers:
1 Select the sprite.
2 Click the Edit: Duplicate menu com-
mand. The Duplicate dialog box opens.
3 Enter the number of Copies you want to
make of the sprite.
4 Enter the number of pixels that each
subsequent copied sprite should be moved
from the preceding one in the Horizontal
and Vertical shifting boxes.
For example, if you enter -10 in each, the
first sprite is duplicated and then posi-
tioned -10 pixels in both directions away
from the original. The second sprite is
positioned -10 pixels in both directions
away from the first copy, and so on.
5 Click OK to close the dialog box.
Tip: If the sprite is not duplicated exactly as
youhadintended,simplyhit the Undo button
andtryitagain.Experiment a little.

13
Retouching image layers
GIF Animator comes with a small, built-in image editor that you can use while in Edit mode.
While not a full-fledged image editor, it does let you make minor corrections and adjustments
to your image layers. This is especially handy for cleaning up resampled layers and scanned
images that may have residue.
To work in Edit mode:
1 Select the layer you want to edit in the
Layer pane.
2 Click the Edit tab to switch modes.
3 Select a tool from the Edit toolbar on the
right hand side of the Workspace and
begin editing.
4 When you’re finished editing, click the
Compose tab or select another layer from
the Layer pane and continue editing.
The Tools:
•Pencil - Draws lines using the Foreground (left-click) or Background (right-click) colors.
•Selection Tools - The 3 selection tools let you make any-shape selections on an image
layer. Filters are applied across all image layers in the region delineated.
•Fill Tool – Fills an area of similarly colored pixels with either the Foreground or Back-
ground colors.
•Eraser Tool – Erases pixels and replaces them with either the Foreground or Background
colors.
•View tools - Lets you zoom-in on and zoom-out of the image, or return it to its normal
view.
•Crop - Opens the Crop dialog box, letting you pare away excess portions of the image.
•Resample - Opens the Resample dialog box, letting you resize the image.
•Flip tools - Let you re-orient the image either horizontally, vertically, left or right.
•Color boxes - Set the Foreground and Background colors respectively. Click to select a
color from either the Workspace or the Palette toolbar.

14
Cropping and resampling images
Another common situation when building GIF animations is to discover, after working on
your image layers in an outside editor, that they are too large to display properly on a web
page. One way to remedy this is to pare away the excess space around the core animation
using the Crop tool. Another solution is to resize the entire animation (or just portions of it)
with the Resample tool. Both tools can be found on the Edit toolbar in Edit mode.
To crop image layers:
1 Click the Crop button on the Edit toolbar
while in Edit mode. The Crop dialog box
opens.
2 Select the image that you want to crop
from the Select source image menu. The
crop settings you apply here can be applied
to all image layers or just to selected
layers.
3 Use the Crop Box in the preview window
to establish which portions of the image
you want to retain (everything inside the
box). You can drag the blue handles to
resize the box and drag the center of it to
position it.
4 Click OK. The crop settings are applied.
To resample image layers:
1 Select the layers you want to resample.
2 Click the Resample button on the Edit
toolbar in Edit mode. The Resample dialog
box opens.
3 Enter the new Width and Height. If you
want the resampled image layers to retain
their relative dimensions, select the Keep
aspect ratio option.
4 Click OK. The image layers are resampled.

15
Merging image layers
There are two ways to merge images in GIF Animator. Simple cross-layer merging allows you
to combine one image layer with another, creating a new image layer that is a hybrid of the
two. Background merging allows you to select multiple layers and then merge each one with a
common background layer.
To merge images:
1 Click the Layer: Merge Images menu
command. The Merge Images dialog box
opens.
2 Select the images you want to merge
together. Images are merged so that the
higher-numbered layers apear in front of
(on top of) the lower numbered layers.
3 Select the Replace original layers option
to remove the selected layers and replace
them with the new merged layer.
4 Click OK to apply the merge settings.
To merge image layers to a background:
1 Click the Layer: Background Merge
menu command. The Background Merge
dialog box opens.
2 Select the background to which you want
to merge the other image layers from the
Background menu.
3 Select the layers to be individually merged
with the chosen background layer.
4 Click OK to apply the merge settings.

16
Other editing tools
GIF Animator comes with other tools to help you edit image layers, offering you a complete
and convenient toolkit to use for your projects.
Aligning images:
To change an image’s physical alignment,
you can use GIF Animator’s built-in trans-
form tools.
1 Select the image layer(s) you want to re-
align.
2 In the Edit mode, click one of the Flip
buttons on the Edit toolbar.
3 The effect is applied to the selected image
layer(s).
Rebuilding ‘broken’ image layers:
Sometimes, after optimizing and then saving
an image, you’ll want to return and edit it
again - but once it’s been optimized, the
frames are ‘broken’. The solution to this is
the Frame Regeneration function.
1 Select the image layer(s) you want to
regenerate.
2 Click the Edit: Regenenerate Frames
menu command. The frames are auto-
matically rebuilt and can be edited.
Note: Insome cases, selectedframes may not
regenerateproperly due tomassive disparity
betweenthem and theirpreceding frames.

17
Working with layer attributes
Each image layer has its own set of ‘controls’ that dictate how that image layer is displayed;
you can decide whether or not it has a Local Palette, define its general position, and select
which color is the transparent color. All the attributes assigned to an image layer, however,
work in conjunction with the other layers, and together they create the properties of the
animation as a whole. Image layers can be selected in the Layer pane, located to the left of the
Workspace.
Global information layer
In addition to the image layers that constitute the animation, there is one layer that contains the
universal properties of the animation as a whole, the Global information layer. Here you can
work with the Global Palette (the color palette from which all image layers can draw color
information), define whether the animation is played non-stop or a set number of times, and
set the dimensions of the Logical Screen. The Logical Screen contains the dimensions of the
entire animation as a whole. It is usually determined automatically by GIF Animator as layers
are inserted and moved around.
To manually adjust the Logical Screen:
1 Select the Global information layer in the
Layer pane. The Attribute toolbar
changes to display the layer’s properties.
2 Deselect the Automatic option under
Logical Screen on the Attribute toolbar.
3 Enter in a new Width and Height. The
Logical Screen (in the Workspace)
changes accordingly.
Note: TheLogicalScreen cannot be smaller than
thelargestimagelayerintheanimation.
To have the animation play endlessly:
1 Select the Global information layer in the
Layer Pane.
2 On the Attribute toolbar, under Looping,
select the Infinite option.

18
Positioning images in the Workspace
Each image layer contains its own set of attributes that pertain only to that layer, even though
the attributes may be the same for every layer. One of the more important attributes is the
ability to position image layers anywhere within the Logical Screen.
To position image layers:
1 Select the layer you want to position from
the Layer pane list.
2 On the Attribute toolbar, enter in the X-
and Y- coordinates for the image (the
coordinate position 0,0 is the top left
corner of the Logical screen).
OR
In the Workspace, click the layer and
drag it to its new position. If you drag it
outside the boundaries of the Logical
Screen, the Logical Screen’s dimensions
are updated accordingly.
Note: Because the coordinates for the Logical
Screen always originate at 0,0 you cannot
enternegative values for an image layer’s
position.
To view other layers as you work:
•In the Layer pane, check the layers that
you want to be visible while you work. By
default, when you’re dragging an image
layer around inside the Workspace, you
can’t see the layers that are under it. By
checking them, you make them visible.

19
To set an image layer’s transparency:
1 Select the layer to which you want to
apply transparency.
2 On the Attribute toolbar, select the Trans-
parent index option.
3 If you know the indexed color value for
the color in the image you want to make
transparent, enter it in the Transparent
index box.
Otherwise, click the Edit tab to switch to
that mode.
4 On the Attribute toolbar, click the Color
box under the Transparent index setting.
Your mouse cursor becomes a color
picker.
5 Select the color you want to make trans-
parent from either the image layer itself
(this only works in Edit mode), or from
the Palette toolbar.
Note:Youcan make multiple layers transparent
simultaneouslybyselectingthemall and then
clickingtheTransparent index option. Selecting a
different color for each one, however, must still
bedonemanually.
Setting an image layer’ s transparency
One of the special features about the GIF file format is the transparency attribute, which
allows you to select a specific color and then make it effectively invisible to all dedicated GIF
viewing software, including web browsers. This lets you create custom shapes that don’t
conflict with the content of your web pages. For example, if you have an image of a basketball
on a black background, and you want your web page to show through the background, you
would make the black color transparent.

20
Removing image layers
In the course of the animation, each image layer must be ‘removed’ from the screen once it
has been displayed. The removal method affects the overall appearance of the animation -
some web browsers, however, don’t support all the removal methods available. You can set an
image layer’s removal method on the Attribute toolbar in the How to remove option. The four
removal methods are described below:
•Web Browser Decides - The image layer
is removed using the browser’s default
method. This method is not recommended
because you will probably get different
effects with different browsers.
•Do Not Remove - The image layer is not
cleared from the screen and all subsequent
image layers are stacked on top of it.
•To Background Color - The image is
removed and replaced with the back-
ground color. This can cause flashing if
used improperly.
•To Previous State - The image layer
disappears in the same manner it ap-
peared. This is generally the best removal
method, but unfortunately, only Microsoft
Internet Explorer supports this at this
time.
Note: InordertomakeGIFAnimationsthatare
