INTRODUCTION• WHAT ARE RASTER IMAGES?Images Generated on Raster Scan Display
Devices.These Images are formed by illumination of
spots called as PIXELS.Each pixel contain information about each
Colour ,Position and its brightness
INTRODUCTIONThus, Raster Images are collection of a large
number of pixels.These Pixels are stored in BIT MAP of the
image in the System Memory which is then viewed by the video controller.
The Figure shows the Scenerio:
INTRODUCTION
RASTER ANIMATION• WHAT IS RASTER ANIMATION?When these such Raster Images when Played
in a Particular Sequence it is called as Raster Animation Sequence.
Each Raster Image is called as Raster Frame.Raster animation forms the more Realistic
Raltime Images.
RASTER ANIMATIONLet us take The Raster scan Display Generating
Raster Scan Image:
RASTER ANIMATIONFor Sequence of such Raster Images The Frame
Buffer in System Memory that Store the Bit Map is refreshed with a new bit map of new image that is to be displayed or Sequenced:
The Figure Shows The scenerio:
T1 s T2 s T2 s
RASTER ANIMATIONThe Following Figure shows 4 Raster images
where the Bitmaps are Loded one by one within the time t1,t2,t3.t4 microseconds
The time when the new Bit map Is decide by the user to Create the Animation.
TYPES RASTER ANIMATIONThere are broadly 2 Types Of Raster Animations:
RASTER ANIMATION
TRADITIONAL MODERN
TYPES OF RASTER ANIMATION
TRADITIONAL RASTER ANIMATION:Used low Detailed Animation using Sprite
SheetsSprite Sheets allowed the Removal of any object
that was not needed, but Disturbed the Animation Sequence.
TYPES RASTER ANIMATIONSPRITE SHEET:
TYPES OF RASTER ANIMATION
MODERN RASTER ANIMATION:Each animation frame is either scanned into a computer.Programming languages such as Flash, HTML and Java is
Used.Generate 2-D animations based on user input events,
such as mouse clicks or keystrokes.Scaled to fit any window with predefined Resolution.

VECTOR VS RASTER ANIMATIONVector animation store image information as a
sequence of points whereas raster animation stores information in form of PIXELS.
Vector Animations does not provide much clarity of image than the Raster Animation generates Real-time Images
Raster Animations are rendered at High Resolutions whereas Vector Animations at Low Resolution.
VECTOR VS RASTER ANIMATIONThe Figure Shows The Difference:
APPLICATIONS3D and 2D Animation RenderingMesh FilteringReal Time Game Designing and GraphicsCartoon Animation to Make ReailisticAnimation Movies
ADVANTAGESGives the animator control over appearance of an
imageRaster Animation Uses less MemoryFlexible and can Remove Selective Objects in
Animation Sequence.Supports 3D object Animation.
DISADVANTAGESRaster files are much LargerBiggest Problem is of Scaling leads to
Multiplication of Each pixel which generates a Blocky pixelated image.
Costly Hardware Devices are Required to Render.
