Relationship between raster graphics and vector

What is the difference between vector and raster graphics?

Feb 13, We've answered that question below and given you a brief explanation on the main difference between raster graphics and vector graphics. Jul 18, There are two types of digital graphics files – vector and raster. Vector images are made of hundreds of thousands of tiny lines and curves (or. Raster, or bitmap, images are made of pixels; little tiny squares of color or shades of black. Vector images are mathematical calculations from one point to.

Vector images are scalable, so one version of a design will always work for every iteration of a project. Vector files are also smaller.

However, vector images cannot display photographs in a natural looking way, and vector formats are not as well supported online as are raster formats. When should I choose raster or vector graphics? For photos you need raster images and Adobe Photoshop; for letterhead, text, logos, and other simple graphic elements, you need vector images and Adobe Illustrator.

You can also create a project that uses both photos and logos, or both kinds of graphics. Finally, remember that you can always turn a vector graphic into a raster file with ease. A raster file cannot typically be made into a vector file. Even if your file extension suggests that the piece is a vector graphic, it may not be; it could have been a raster graphic that was opened in Illustrator and saved, for example.

The only way to know for sure is to open the file and get a close up look at part of the design. Conclusion For clear images like photos that convey subtle gradations of color, shade, and light, raster images are perfect despite their loss of quality at larger scales and occasionally unwieldy file sizes.

For scalable designs with fewer colors, vector graphics are ideal, despite their inability to render totally smooth color transitions. To cover all of your bases, have your design in both formats, or in vector form to be converted later. On the contrary, you need a particular size of a raster format to achieve a certain quality.

File size Vector images are quite lighter than their raster peers because their dimensions are defined by mathematical calculations and not by millions of pixels.

The high efficiency of their file sizes makes them much more convenient to transfer them from one device to another.

On the other hand, raster file sizes are defined by their DPI or PPI, fixed widths and heights, which makes them much heavier while containing less information. Also, most digital images on the web are actually bitmaps even if they were vectors once.

For their printed version, though, you have two options. The higher the dpi, the better the resolution. Thus, high resolution images should only be used if your equipment has the capability to display them at high resolution. Better resolution, however, comes at a price. Just as raster files are significantly larger than comparable vector files, high resolution raster files are significantly larger than low resolution raster files.

Overall, as compared to vector graphics, raster graphics are less economical, slower to display and print, less versatile and more unwieldy to work with. Remember though that some images, like photographs, are still best displayed in raster format.

Despite its shortcomings, raster format is still the Web standard — within a few years, however, vector graphics will likely surpass raster graphics in both prevalence and popularity. Unlike pixel-based raster images, vector graphics are based on mathematical formulas that define geometric primitives such as polygons, lines, curves, circles and rectangles.

Because vector graphics are composed of true geometric primitives, they are best used to represent more structured images, like line art graphics with flat, uniform colors. Most created images as opposed to natural images meet these specifications, including logos, letterhead, and fonts.

Inherently, vector-based graphics are more malleable than raster images — thus, they are much more versatile, flexible and easy to use.
