Their use is limited, however, and they are most suitable for typography, line art, and illustrations. Because mathematics can be easily scaled, this type can be enlarged but still have smooth edges. A vector image defines points and the paths that connect them to form a digital representation of the image. What is a vector image?Ī vector image uses a mathematical formula to draw a picture. Depending on resolution, some images can be enlarged to very large sizes, while others quickly become difficult to see. While this effect is sometimes a deliberate choice on the part of an artist, it is usually not desired. When blown up, however, the individual dots of color become apparent. When the image is viewed, the pixels usually smooth out visually for the user, who sees a photograph or drawing. In photographs with subtle shading, this can be extremely valuable. An RGB value of 0,0,0 would be black, and the values go all the way through to 256 for each color, allowing the expression of a wide range of values. This format uses the red, green, blue (RGB) color system. Each pixel is assigned a specific value that determines its color. When a raster image is created, the image on the screen is converted into pixels. These pixels form points of color that create an overall finished image.

The image is represented in a series of bits of information that translate into pixels on the screen. It can be created in a wide variety of formats, including the familiar.

What is a raster image?Ī raster image, also called a bitmap, is a way to represent digital images. Most of the images are set at a web resolution of 72dpi, which isn’t high enough for print and the images may appear blurry or pixelated when printed. It is not advisable to ‘lift’ images from websites. If you are scanning the images yourself from photographs, set the resolution to at least 300dpi (dots per inch). What types of images will reproduce well for print?Īll images used in a project should be high-resolution raster or vector files.
