Why do some images blur when resized? Why can other images be scaled to any size without loss of quality?
Generally speaking, there are two types of computer graphics - Raster and
Vector graphics. If you use graphics often, understanding these two formats and
how they are created is essential.
To put in a nutshell, Raster images get blurred when they are resized and
Vector images can be scaled to any size without loss of quality.
Raster image vs. Vector image
(a) Raster image - also referred to as "bitmap", "digital" or "paint" graphic. Digital cameras and scanners produce JPG images, as are most of the graphics you see on the Internet. JPG format images allow
whole images to be rotated, edited, cropped, filtered and scaled using photo editors such as Adobe Photoshop. However sophisticated graphic skills are required.
When inserting raster images into your presentation slides, slides risk quality loss and blurring once resized. Since you have limited chances to change images, it is difficult to keep consistency and quality throughout the slide show.
(b) Vector image - also referred to as "draw" graphic. Vector images are created using geometric objects - lines, ovals, rectangles, and curves. Vector
images can be rotated, edited and ungrouped so that
any component shapes can be edited, deleted, or re-colored using virtually any vector
graphic editors such as Microsoft Office PowerPoint or Adobe Illustrator.
When using vector images in the presentation, the display quality of slides never changes regardless of resizing. As a result, consistency and quality throughout the slide show can be guaranteed.
All of images we develop are vector images. With our images, you are in full control of your
slide presentations.
