How to vectorize an image

Vector Image

A vector, on the other hand, is also known as object-oriented graphics. The images are constructed using mathematical formulas describing colors, shapes, and placement. In a bitmap, it is a grid of pixels that form the image, while a vector graphic consists of shapes, curves, lines, and text to make a picture.

A vector graphic contains instructions on where to place the various components. It is even possible to embed a bitmap graphic within a vector graphic. Moreover, it is composed of many lines as compared to bitmap images. It also has a smaller file size and can be made infinitely.


Comparison between a bitmap image and a vector image

Also, a bitmap graphic tends to be much larger than a vector graphic. Bitmap graphics are easily affected by resolution. However, vector graphics are not affected easily, and instead, their shapes are redrawn to compensate for the change in resolution.

It is easy to convert bitmap files to another and also convert vector graphics to a bitmap. However, it is hard to convert a bitmap graphic into a true vector graphic. Vector graphics are also not appropriate for complex images.

Common bitmap formats:

  • JPG – Joint Photographic Experts Group
  • BMP – Bitmap Image File
  • GIF – Graphics Interchange format
  • EXIF – Exchangeable Image File
  • PNG – Portable Network Graphics
  • TIFF – Tag Image File Format

Common vector formats:

  • SVG – Scalable Vector graphics
  • .ai – Adobe Illustrator
  • EPS – Encapsulated PostSCript
  • PDF – Portable Document Format
  • WMF

step4

  • After the process, if you are not satisfied with the selected range, use the pen tool to adjust and add or remove the anchor points. If the anchor points have an inaccurate position, hold down the Ctrl key and use the left mouse button to adjust positions.

step5

  • Then select the tool to create the vector mask of your image. The next step is to export the vector paths by clicking, File > export > paths to illustrator.
