Need of Vector Images in Digital World


Image or photograph is integral part of any digital platform like website, social campaign, and community or business institution. Sometimes, we use image entity to represent entire institution or deliver some facts. Logo is best example which is used for different purpose like press release, online store, business paper and digital marketing.

When we circulate a logo at vast level then we should ensure that image shouldn’t fade their look & feel at user’s end. But, it can’t possible by raster image.

Why Raster Image is not perfect for web?

Raster images are producing through the process of scanning source artwork or “painting” with a photo editing editor. Some popular editors are Corel Photo Paint and Adobe Photoshop.

Raster image is made of series of dots, which is known as pixels. Each pixel of raster photo is a tiny colored square. At initial stage, when we are scanning an image then photo is converted into raster image.

We can identify scanned graphic image with following formats:

  1. CPT (Corel PhotoPAINT)
  2. BMP (Windows Bitmap)
  3. PCX (Paintbrush)
  4. TIFF (Tag Interleave Format)
  5. PSD (Adobe PhotoShop)
  6. PNG (Portable Network Graphic)
  7. JPEG
  8. IMG
  9. JPG

Above image format are delivering low quality of resolution on web. Along with degraded picture quality, you can’t increase size of image due to reason of distortion.

Process to Build Vector Image:

Vector Image is based on mathematical equation as well as geometry objects like line, curve and polygon etc. Finally, we can say that it is a connected path of lines and curves. By using the mathematical description, we can generate vector objects like node position, location of node, length of line and curve. Vector image is an object oriented that’s why it can be used without hampering picture quality. In a vector object, colors are mapping on the top of a skeleton. For creation of Vector graphics, top most editors are CorelDraw and Adobe Illustrator. These editors have potential to manipulate raster images into higher quality of raster image.

Vector file formats are available with following extensions:

  1. EPS (Encapsulated PostScript)
  2. WMF (Windows Metafile)
  3. AI (Adobe Illustrator)
  4. PLT (Hewlett Packard Graphics Language Plot File)
  5. SVG (Scalable Vector Graphics)
  6. CDR (CorelDraw)
  7. DXF (AutoCAD)

Presence of Vector Photographs:

Vector image is enabled with line objects so we can increase such kind of image at any level. It allows the designers to reuse existing image with different size. It also boosts the image resolution of scanned image with higher level of user engagement.

Due to high quality, digital world is accepting vector image for increasing visitors. Apart from corporate world, high quality of vector images are demanding by mid level agencies/professional like wild life expert, weeding photographers, online advertiser, tour operator, cloth designer, retailers and fashion advisors.

Graphic experts are also recommended to use vector logo. This approach encourages the marketer to use logo on different locations with distinct size.

Overall! We can say vector format is helpful for managing digital world with meaningful picture quality.
