After the first part of “Explaining The Difference Between Raster and Vector Images” article.
A raster image is made up of thousands of little dots or pixels, photo editors like- Adobe Photoshop are raster based and are great for rendering rich, full color images like photographs. Raster based programs do have some drawbacks though.
Photographs are not vector image or vector graphics. Only Illustration that can made to look like photographs can be created in a vector workplace.
So far we’ve looked at bitmaps and vector graphics individually. Now let’s summarize a bit and repeat this information as we balance some points about these graphic form.
There are two types of digital graphics files – Vector and Raster. Vector images are made of hundreds of thousands of little lines and curves (called clipping path) to create an image. Raster images are composed of pixels.
Many of poor quality scans were created on expensive large format scanners whose product literature glows with the promise of quick and easy high quality scans. Though as the scans we receive show, there is no assurance of useful results when the scanner is used inappropriately for the drawing in hand.
This article sets out simple steps for ensuring high quality scans. It is intended most specifically at users wanting to scan drawings for raster to vector conversion but once you have mastered this relatively simple process that largely a matter of learning to read your drawings and to use your scanner correctly that you will also be able to apply the improvements in image quality to the archiving of important drawings in order to give them and posterity the quality they deserve.
Raster to Vector is a separate program that converts scanned drawings, maps and raster images into accurate vector files (like-DXF, HPGL, WMF, EMF etc) for editing in any image.
A raster to vector converter converts a raster image to a vector image. it basically Convert Bitmap Images To Clean Vector Art. repeatedly convert bitmap images like JPEG, GIF and PNG to the crisp, clean, scalable vector art of EPS, SVG, and PDF with the world’s best auto-tracing software.
Generally, main different is input and out file. Normally, input raster image formats are BMP, JPG, TIF, GIF, PNG, PCX, TGA, RLE, JPE, J2K, JAS, JBG, MNG and more. And output vector formats are DXF, HPGL, EMF, WMF and others.
Final Product What You’ll Be Creating
In this tutorial we will use the 3D capabilities of Photoshop CS5 Extended to create a chocolate volcano and text effect. Let’s get started!
