Vector Graphics: Its use and drawbacks
Is it possible for an image to keep its quality when resized to bigger shape? Yes, it can be done. If you still have doubts, use vector graphics to experience this.
Vector images consist of lines and curves. This is a different type of file format from bitmap or raster files that use pixels or dots to form image. The image quality does not drop due to scaling.
Benefits:
1) As vector images are highly scalable, they can be used for making logos. Operations like rotation, skewing, resizing are also possible keeping the image quality intact. Those graphics where quality will remain intact due to scaling, should use vector graphics format.
2) Vector graphics are especially useful for line art or drawing outlined pictures.
3) Vector graphics are very useful for printing purpose. From a print out of A4 size to a print of Billboard size, vectors graphics can give you same quality in both the cases.
4) In 3D modeling and designing, vector graphics are used to represent geometric details.
Problems:
Vector graphics can’t be applied in all the design process. They come with the following limitations:
1) Graphics of format can be opened in the particular software where they were designed. To open a specific vector file particular software will be used. AI files can be open in Adobe Illustrator, CDR files can be open in Corel Draw, FH files can be opened in Freehand, FLA and SWF files can be opened in Macromedia Flash. Encapsulated Postscript (EPS), Scalable Vector Graphics (SVG), 3DS (for 3Ds Max), DWG, Drawing Exchange Format (for AutoCAD) are also opened with specific vector file supporting software.
2) No vector graphics can be displayed in browsers or on internet unless they are converted to standard image viewing formats like .JPEG, .BMP, .PNG and .GIF.
3) Special graphical effects can be applied less in case of vector graphics. Photo editing software is used separately for that.
Vector graphics are widely used where image quality and outline is the main concern. Software like Corel Draw, Adobe Photoshop, Autocad, 3Ds Max have gained popularity in printing, logo and graphics design and 3D modeling because of vector graphics drawing facility.
Despite popularity of raster graphics, vector graphics are largely in use. And their usage will be more with advancement of web technology, gaming and animation.
