Raster Design Based on Adobe Photoshop at IIT

What is Raster Design?

Create lines and polylines from raster images, and convert raster files into vector drawings. Image transformation functionality. Show and analyze geo images in Civil 3D civil engineering software and the AutoCAD Map 3D toolset.

Overview

The Raster Design palette provides comprehensive image data including image properties, image colors, and image file location. Specialized tools that give the same results as basic AutoCAD with quicker, more efficient workflows.

Frequently Asked Questions

Is raster design included in Civil 3D?

Since Raster Design integrates completely with Civil 3D, when converting from a scanned map, you can generate contour lines as polylines with true elevations. Figure 10: Use Raster Design to convert scanned topography into polylines with elevation.

What is raster design used for?

Create lines and polylines from raster images, and convert raster files into vector drawings. Show and analyze geo images in Civil 3D civil engineering software and the AutoCAD Map 3D toolset.

What is raster in graphic design?

Raster images are made of pixels, or tiny dots that use color and tone to produce the image. Pixels appear like little squares on graph paper when the image is zoomed in or enlarged. These images are created by digital cameras, by scanning images into a computer or with raster-based software.

What is raster file?

A raster image file is a rectangular array of regularly sampled values, known as pixels. Each pixel (picture element) has one or more numbers associated with it, specifying a color which the pixel should be displayed in.

What is raster vs vector?

Digital graphic files will generally fall into one of two categories—vector or raster. Vector graphics, such as logo files, use intricate paths made up of points and lines to create an image. Raster graphics, such as digital photographs, are created using a grid of tiny pixels.

What are the advantages of raster graphics?

Some advantages of raster graphics include the following: they are easy to use; they provide subtle gradations of color; and they are simple to edit using common programs like Photoshop and Microsoft Paint.

What are the characteristics of raster images?

These are the types of images that are produced when scanning or photographing an object. Raster images are compiled using pixels, or tiny dots, containing unique color and tonal information that come together to create the image. Since raster images are pixel based, they are resolution dependent.

What is the meaning of raster image?

Raster graphics, also called bitmap graphics, a type of digital image that uses tiny rectangular pixels, or picture elements, arranged in a grid formation to represent an image.

How are raster images stored?

There are three methods to store image and raster data: as files in a file system, within a geodatabase, or managed from within the geodatabase but stored in a file system. This decision also involves determining whether to store all the data in a single dataset or in a catalog of potentially many datasets.

How are pictures created in raster scan system?

In raster scan system electron beam sweeps across the screen, from top to bottom covering one row at a time. A pattern of illuminated pattern of spots is created by turning beam intensity on and off as it moves across each row. A memory area called refresh buffer or frame buffer stores picture definition.

What is raster printing?

When printing in rasterized mode, all the graphics in the design are converted into raster by the MicroStation display system before being sent to the printer driver. The final plot file (or data spooled through Windows) consists of only non-overlapping raster tiles.

What is raster data in GIS?

Rasters are digital aerial photographs, imagery from satellites, digital pictures, or even scanned maps. Data stored in a raster format represents real-world phenomena: Thematic data (also known as discrete) represents features such as land-use or soils data.

What is the resolution of raster image?

The spatial resolution of a raster refers to the size of the cells in a raster dataset and the ratio of screen pixels to image pixels at the current map scale. For example, one screen pixel can be the result of nine image pixels resampled into one—a raster resolution of 1:9.

What is the best raster to vector conversion software?

CSoft provides two choices for raster editing and raster to vector conversion. One of them – WiseImage for Windows and another one is the WiseImage for AutoCAD( an application running inside AutoCAD) The best raster editing software.

What are the advantages of raster and vector data?

Data can be represented at its original resolution and form without generalization. Graphic output is usually more aesthetically pleasing (traditional cartographic representation); Since most data, e.g. hard copy maps, is in vector form no data conversion is required.

Why raster are effective in creating logo in graphics design?

Very Precise Editing – With raster logos, you can modify the color information on each of the individual pixels, one by one. If such precision is what you are looking for, then you should go with raster images for your logo design. Adobe Photoshop can also be used to create vector files.
