A Roundup of Vector Conversion

As a part of Photo editing and retouching, raster to vector image conversion is a sophisticated and value driven work. Being a challenging, tiptop, and technical job, vector converting is a tricky and costlier than any other image processing. Vector artists must have a perfect combination of skills, techniques, and firm patience to get professional vector graphics from raster images.

Though the primary purpose of vector arts is to achieve stunning print images, now-a-days, vector images are being utilized for advertisement and marketing of various business sectors. The use of vector images is increasing gradually in the digital fields and as a result, the demand of image to vectorization services is also getting skyscraper.

However, what we are talking about so far! Do you want to get the concept of vector conversion vivid? Just dive into the roundup of an image to vector converting.

What is Vector graphics or vector conversion?

Vector conversion is a part of photo editing and retouching. It is a process of transforming raster images into vector formats. No camera can produce vector artwork. So, vector graphics are created using photo compositing software. Raster images go through some processes to vector physical images like printing, signage, engraving, ambushing, glass etching, and many more.

Vector graphics are defined as points on a Cartesian plane. These points are connected by some lines and curves. They form shapes like circles, triangle, polygons, etc. Due to having the points, lines, and curves, vector graphics can be scaled up at any range without losing image quality related to stroke color, curve, shape, fill color, and thickness.

Raster Image Vs. Vector Graphics

If you examine raster and vector images keeping side by side, you will have a lot of specific differences. Both the images have some advantages and disadvantages in terms of their uses. Let’s have a look on the basic dissimilarities between the two image formats-

Raster graphics are formed of numerous tiny dots or squares called pixels. They are arranged in a grid and make visible as a photograph. Each pixel can contain different color or light. The amount of pixels determines the resolution of an image. The more pixels an image has, the more detail and clear the image is and its resolution will be higher. The resolution is measured by the pixel dimension that determines the raster image size. Raster images are also called bitmap images.

What are raster graphics?

Raster graphics are made up of numerous of tiny squares called pixels. Each square represents a different color or lightness. These pixels are arranged in a grid. When zoomed out, this tightly woven grid creates a photograph or image. You may also hear them referred to as a "bitmap".

The amount of pixels in an image determines its resolution. The more pixels an image contains, the more detail that is captured—and the higher its resolution; likewise, fewer pixels capture less detail and result in lower-resolution images. Resolution is measured by pixel dimension—the number of pixels that make up the width and height of an image. A 480 x 270 pixel graphic is lower resolution than a 1920 x 1080 pixel graphic. If you’re not sure of your file’s pixel dimension, look at the file size, measured in kilobytes (KB) or megabytes (MB). Generally speaking, if a file is measured in KB, it’s low-res; if it’s 5 MB or more, it’s high-res.

If you find an image on an internet image search, it is likely a low-resolution raster file.

Technically Speaking:

DPI and PPI are two terms that are used to reference raster graphic resolution. They are confusing because they have been used interchangeably, but they are not the same.

DPI – Dots Per Inch. DPI is used in the printing process, and it describes the number of dots a printed document has per inch. In a printed image the more dots, the higher quality the printed piece is.

PPI – Pixels Per Inch. PPI is used digitally, and means the number of pixels your digital image has per inch on your screen.

Where are Raster Graphics Used?

Photographs and scanned images are the most common examples of raster graphics. Raster graphics often show more subtle changes in color, tone, and value than vector graphics are able to achieve. Unlike a vector graphic, it is impossible to take a small raster graphic and scale it up without losing image quality.
Raster graphics or images are captured by a digital camera or scanned into the computer and edited by programs such as Adobe Photoshop. Typical file formats include .jpg, .psd, .png, .tiff, .bmp, and .gif. However, both raster and vector graphics can be saved as .eps and .pdf.
So, how can you tell if an .eps or .pdf is really a vector graphic? If you don’t have Illustrator or Photoshop, you can zoom in on a file and check to see if the graphic retains a clean edge (vector) or becomes jagged (raster).

What are vector graphics?

Vector graphics are created from mathematical paths, curves, and points. This produces a sharp, clear edge. Vector graphics are able to scale up or down infinitely without losing quality, so they retain the same crispness when printed on something as small as a business card or as large as a billboard. But, unlike raster graphics, vector graphics usually cannot achieve photo realism.
Fonts are the most commonly used vector graphics, and they demonstrate how well a vector graphics scale. Look at the different sized letterforms below to see how the clean edge holds up at all sizes.

Where are vector graphics used?

Outside of screenprinting, Vector graphics are used in text, logos, illustrations, symbols, infographics, charts, and graphs. They are created and edited in computer programs such as Adobe Illustrator and, Corel Draw. Typical formats for a vector file are .ai (Adobe Illustrator file), .cdr (Corel Draw file) .eps or .pdf. However, not all .eps or .pdf files are automatically vector-based. To understand why we need to explore raster graphics.
