#VECTOR AND RASTER IMAGE HOW TO#

But with vector images, you're saying, 'fill the background with a left-to-right gradient that fades from blue to pink. With raster images, you're basically telling your computer, 'this pixel should be blue, the next one should be purple, the one after that should be pink,' and so on. Vector images are composed of shapes wherein each shape has its own solid color. First, notice that both datasets plot fine individually. Below is an example of what happens if you do not define the plotting extent for a plot overlaying vector and raster data (array). Importance of Using Appropriate Plotting Extents.

If that technical explanation didn't make much sense to you, think of it this way. Map of the cropped NAIP RGB imagery overlayed with the Cold Springs Fire vector layer. Text is one of the most common types of vectors! Photoshop supports creative projects ranging from photo editing and compositing to digital painting, animation, and graphic design. Changing the size of the raster image mostly results in loss of apparent quality. This formulaic approach allows vector images to be scaled to any size without losing their quality. A Raster graphics image is a rectangular grid of pixels, in which each pixel (or point) has an associated color value. Vector images, meanwhile, are composed of lines called 'paths' and points called 'anchors.' They dictate how an image should render based on mathematical theory. With larger raster images solved, we move forward to think about vector images. When to use Vector Graphics: When you are designing something for large scale like banners, signage, vehicle wraps and other large format items. The powerful thing about vector images is that you can resize them from 1 inch by 1 inch to 1 mile by 1 mile without the loss of. In computer graphics and digital photography, a raster graphics represents a two-dimensional picture as a rectangular matrix or grid of square pixels, viewable via a computer display, paper, or other display medium.

In contrast, a vector image is created using lines and curves. Raster images are great for use on the web.

This results in an unattractive, blurred image-at least, in most cases. In doing so, you're asking the image editor to add more pixels where there aren't any more. Usually, raster images can't be scaled any larger than their original width and height.

Each pixel contains data that determines its color, such as its hue, saturation, value, transparency, etc. Every content creator working with visuals will come across vector and raster imagesthe two most common file formats available on the market. Raster images (or bitmaps) are composed of pixels.
