Raster Image Processing is performed by which electronic component in the electrographic printer?
Formatter
What is raster printing?
Raster printing refers to the method of printing which uses the raster image processor. The raster printing usually produces a raster image called a bitmap.
How does a digital printer work?
Digital printing begins with creation of the document file ‰ÛÒ the words and images that will print on the page. Regardless of what program is used to create the file or any of its components, the file is converted into a raster graphics image. A raster is a grid of x and y coordinates on a display space; a raster image file identifies which of those coordinates to illuminate. A raster image file is sometimes referred to as a bit map because it contains information that is directly mapped to the display grid. BMP, TIFF, GIF and JPEG are all examples of raster image file types. The action of converting a file to a raster image file is known as raster image processing or RIPping.
Difference between Digital image processing and computer graphics?
There is always a confusion among the newbies about the difference between Image Processing and Computer Graphics. Unless specifically mentioned , Computer Graphics is all about Synthesizing a new image from Geometry , Lighting parameters , Materials and Textures . The Emphasis is on Digital Image Synthesis. Image Processing is the process of manipulating an image acquired through some device . The image too often will be acquired from photographs,scanners , medical equipments. The emphasis is on Analysis and Enhancement of the image. Computer Vision is an area where Image Analysis is used a lot. Raster Operations dominate in the case of image processing. In the case of Computer Graphics , you will mix vector and raster operations to generate the final image.
What produces a raster image and what produces a vector image?
raster image = monitor, laser printer or ink-jet printer vector image = graphics plotter

What is another term for Raster Graphics?

Is Adobe Photo shop a raster or bitmap editor?
Photoshop is a raster image editor. Raster and Bitmap are two words for the same thing, so Photoshop is raster or Bitmap image editor, somewhere you will see raster, somewhere bitmap as explanation but it is basically same thing. Photoshop is primarily designed to work with bitmap images which are raster images in other words.
What happens when a raster graphics is resized?
raster graphics cannot be resized without losing image quality
What is digital image processing?
Image processing is the method of processing data in the form of an image. Image processing is not just the processing of image but also the processing of any data as an image. It provides security.
What is a raster device?
Common examples of raster devices are computer monitors (e.g. cathode ray tube, LCD). The term "raster device" means a device that is composed of discrete image samples or pixels.
What is the difference between a raster and image data?
Raster IS a type of image data another type is VECTOR.Raster deals with picture elements (pixels) these are discrete bits of the picture , small dots or swuares that together make up the entire image).Vectors deal with mathematical expressions for lines and areas. You can zoom in invinitely into a vector image and neve get blocks or jaggged edges which appear in raster images.
