• TRANSPARENCY, Compression , Interlacing, various colors palettes are applied
• No plug-ins or supported software required.
• No web server or server side includes or PERL scripting is needed.
• PROVIDES reusable and repeatable animations.
• No need to download the ANIMATION constantly by MODEM, as the whole animation is loaded only once.
• The size of animated images is COMPACT.

• Image block is the actual image.
• The SIZE of the image can be of any size.
• The palette of the image can be of any size.
• Other information includes:
  
  1. Size of the picture in pixels.
  2. POSITION of the image on Logical Screen
  3. Local palette for the image.
  
  
• The size of the image cannot be MODIFIED.
• Changing the image size CASES data CORRUPTION.

• It is ALWAYS a second BLOCK in GIF file.
• An AREA of pixels usually referred as screen, is defined by LSD.
• GIF file SIZE is defined by this area.
• When the logical screen is larger than the image, some space is displayed AROUND the image.
• As per the size of the images, the logical screen size need to be set based on the width and height of the images.

Logical SCREEN Descriptor has the following information.

• Logical Screen Width: The width of the image that REPRESENTS in PIXELS
• Logical Screen Height: The image height in pixels.
• Packed FIELD: The element of the image for ANIMATION.
• Background Color Index: A value that is pointing to a color in the Global Color Table.
• Pixel Aspect Ratio: The approximate aspect ratio of the pixel in the GIF image

Logical Screen Descriptor has the following information.

• XAML stands for eXtensible APPLICATION Markup Language.
• XAML is known as a declarative markup language.
• XAML simplifies UI creation for .NET Framework applications.
• Has flexibility to CREATE UI elements in XAML and separate the UI definitions from runtime logic.
• Code behind files support separating UI definitions from runtime logic.
• XAML work flow includes separate elements to work on UI design, BUSINESS logic by using different potential tools.
• XAML can be REPRESENTED as text files in as XML files and XML encoding is applied to it by using UTF-8 standard.

PNG and MNG are the alternatives for GIF.

PNG:

• GIF IMAGES are limited to 256 colors.
• PNG format supports palette-based images, Gray Scale images.
• PNG ALSO supports full color NON palette based RGB images.
• PNG format is SUITABLE for transferring images on INTERNET.
• PNG is not for professional-quality print graphics.

MNG:

• MNG is closed to PNG format.
• Better compression standard than GIF
• Integration of PNG and JPEG based images.
• Supports transparent JPEG images.

PNG and MNG are the alternatives for GIF.

PNG:

MNG:

• Displaying of a SINGLE frame of video into two frames.
• Each frame is split into ALTERNATING lines.
• The FIRST frame displays odd numbered lines, and the second frame displays even numbered lines.
• The resolution per frame is 480 horizontal lines.
• The NUMBER of frames displays per second would be 30.

• COLORED table is represented by a sequence of bytes that represents RED, Green and Blue color triplets.
• GLOBAL Color Table is used for images with plain text extensions.
• Every global color table’s presence is marked by the Global Color Table Flag.
• The GCT Flag is set to 1 in Logical Screen Descriptor.
• The BLOCK contains the number of byes equal to 3 x 2 size of global color table + 1
• One Global Color Table is present per DATA Stream.

• GIF file has fixed size GRAPHICAL area.
• It contains one or more images.
• EVERY image can be animated by placing them in animation frames.
• Every PART of GIF file is a frame.
• All such frames make the complete graphical area or logical screen.
• Every file starts with a fixed length header.
• Every logical area consists of an image, the extension block and the TRAILER that is referred as the last byte of the file.

• ANIMATION of text FADE is DONE with fireworks. 
• The changed opacity is from 0% to 100% over a set of frames.
• Later the animation is reversed with another text object with opacity from 100% to 0%

• MGF file format retains all INFORMATION about objects in the animation.
• GIF CONTAINS only fixed IMAGES, and HENCE it is less flexible.
• Place all EDITABLE files in a MGF file, before creating GIF files.

• A phenomenon of the eye.
• By this an after IMAGE is persisted approximately 1/20th of a SECOND on the retina.
• HUMAN perception of motion is the end result of vision persistency.
• Visual form of memory that is referred as Iconic Memory is the cause of PERSISTENCE of Vision.
• The persistence of vision has two distinct illusions – 1. Phi Phenomenon and 2. Beta Movement.

Animation:

• Animation involves drawing of sketches of OBJECTS.
• These objects are placed in various frames, so that it ILLUSTRATES as if the objects are moving.
• Animation is created by drawing series of illustrations in DIFFERENT angles. 
• Animation creation is difficult compared to creating a video.

Videos:

• Videos are made by using video cameras.
• The real MOVEMENTS of objects are CAPTURED by shooting the videos.
• Manual intervention is not necessary to shoot.

Animation:

Videos:

• Using fewer COLORS allows reducing the file size.
• Limiting colors and using similar colors from frame to frame.
• To decrease the file size, one more method is to cut down the pixel dimensions.
• The number of frames should be the EXACT number for the specified animation.
• IDENTIFY the file reduction feature in the software that creates GIF image files.
• IMPLEMENT dithering. Dithering reduces the banding. The image appears smoother by ELIMINATING colors.

• Beneton Movie GIF allows to create GIF images for greeting CARDS.
• BM GIF animation MAKER is FULL FEATURED software that is simple to use and create GIF images.
• Any image file can be taken as an input file and can be converted to 48 animated file formats.
• Among all, GIF format file creation is WELL suited for presentations.

GIF Format:

• LZW compression standards are used in GIF IMAGES.
• Traces the colors of the IMAGE and reduces the size of the file.
• Best suited for simple animated graphics on the web.

PNG Format:

• PNG(Portable Network Graphics) is a graphic file format for lossless compression.
• It is suitable for RASTER images storage.
• Indexed-color, grayscale and TRUE color images are supported in PNG format.
• SUPPORTS cross platform image brightness and color correction.

GIF Format:

PNG Format:

• Ambient OCCLUSION is related to bright the light to shine on specific surfaces.
• AO is based on the environment of the surface.
• The calculation is done by CASTING rays in each and every DIRECTION from the surface.
• The brightness is increased on the surface by focusing the rays from the BACKGROUND.
• Points with little geometry will appear light on the VISIBLE hemisphere.

GIF images use the following compression techniques:

• Lossless Compression: STATISTICAL redundancy is exploited for representing data in more CONCISE manner.
• Real-world data CONSISTS of statistical redundancy.
• Lampel-Ziv Compression: One of the most POPULAR ALGORITHMS. 
• Compression process is slow.
• It implements table-based compression, in which the table entries are substituted to repeat the strings of data. 
• The table is encoded using Huffman encoding.

GIF images use the following compression techniques:

• Animation is REFERRED to rapid display of a set of 2D IMAGES in a SEQUENCE.
• It CREATES an illusion of movement of objects / displays.
• Most common animation method is a MOTION picture.
• Full animation is referred to producing high quality motion pictures.
• Limited animation involves less stylized drawings and methods.

• GIF is a format of bitmap image.
• It SUPPORTS maximum of 8 BPP.
• It allows a single image to be referenced as a palette.
• Each palette has up to 256 colors to choose from.
• The RGB color SPACE is about 24 BITS.
