Question 10. What Is Persistence Of Vision?
A phenomenon of the attention.
By this an after image is continued approximately 1/20th of a 2d on the retina.
Human belief of movement is the cease end result of imaginative and prescient persistency.
Visual shape of memory this is referred as Iconic Memory is the purpose of Persistence of Vision.
The endurance of vision has distinct illusions – 1. Phi Phenomenon and a pair of. Beta Movement.
Question eleven. What Is The Reason To Use Mgf File To Convert Imported Images Into Bitmaps?
MGF file format keeps all data about items within the animation.
GIF consists of most effective constant photos, and for this reason it's far much less flexible.
Place all editable documents in a MGF file, earlier than developing GIF documents.

Question 13. What Is The File Structure Of Gif?
GIF report has constant length graphical region.
It carries one or more photographs.
Every photo can be animated by using placing them in animation frames.
Every part of GIF report is a body.
All such frames make the complete graphical location or logical display.
Every file starts with a set period header.
Every logical place consists of an image, the extension block and the trailer that is referred because the remaining byte of the file.
Question 14. What Is The Purpose Of Global Color Table?
Colored table is represented by means of a sequence of bytes that represents Red, Green and Blue coloration triplets.
Global Color Table is used for pix with undeniable text extensions.
Every international color table’s presence is marked via the Global Color Table Flag.
The GCT Flag is ready to one in Logical Screen Descriptor.
The block carries the wide variety of byes same to three x 2 length of worldwide color table + 1
One Global Color Table is present in step with Data Stream.
Question 15. What Is Interlacing?
Displaying of a single body of video into frames.
Each frame is split into alternating strains.
The first body presentations bizarre numbered traces, and the second body presentations even numbered traces.
The decision according to frame is 480 horizontal strains.
The quantity of frames presentations per 2d would be 30.
