GIF is not a data compression method. The original version of GIF is known as GIF87a. It is graphical image format that uses variant of LZW to compress the graphical data and allows to send image between different computers.
LED is a type of LCD that actually accompanies the advancement of technology. This replaces the fluorescent tube with backlight technology, which produces a clearer picture than the LCD. LED have wider viewing angle than the LCD.
We need to plot the perimeter points of a circle whose center co-ordinates and radius are given using the Mid-Point Circle Drawing Algorithm. We use the above algorithm to calculate all the perimeter points of the circle in the first octant and then print them along with their mirror points in the other octants.
Flood fill algorithm is also known as a seed fill algorithm. It determines the area which is connected to a given node in a multi-dimensional array. This algorithm works by filling or recolouring a selected area containing different colours at the inside portion and therefore the boundary of the image.
MP4 is a digital multimedia container format Mp3 is an audio coding format Extension used is .mp4 Extension used is .mp3
What is Random-Scan Display ?
In Random-Scan Display electron beam is directed only to the areas of screen where a picture has to be drawn. It is also called vector displays, as it draws picture one line at time.
Raster Scan Displays are most common type of graphics monitor which employs CRT. It is based on television technology. In raster scan system electron beam sweeps across the screen, from top to bottom covering one row at a time.
Boundary Fill Algorithm starts at a pixel inside the polygon to be filled and paints the interior proceeding outwards towards the boundary. This algorithm works only if the color with which the region has to be filled and the color of the boundary of the region are different.
Given a rectangle, your task to fill this rectangle using flood fill algorithm. Examples: Input : rectangle(left = 50, top = 50, right= 100, bottom = 100) flood( x = 55, y = 55, new_color = 12, old_color = 0)
Midpoint ellipse algorithm plots(finds) points of an ellipse on the first quadrant by dividing the quadrant into two regions. Each point(x, y) is then projected into other three quadrants (-x, y), (x, -y), (-x, -y) i.e. it uses 4-way symmetry.
