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. If that technical explanation didn't make much sense to you, think of it this way. Text is one of the most common types of vectors! This formulaic approach allows vector images to be scaled to any size without losing their quality. Vector images, meanwhile, are composed of lines called "paths" and points called "anchors." They dictate how an image should render based on mathematical theory.

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. Vector graphics are not appropriate for complex images (e.g.Raster images (or bitmaps) are composed of pixels.It is even difficult toĬonvert one kind of vector graphic into another (e.g., PICT to WMF). However, it is very difficult to convert aīitmap graphic into a true vector graphic. You can also convert a vector graphic into a bitmap. You can easily convert one kind of bitmap file into another.Most paintĪpplications, however, are capable of opening many different kinds of While many Mac OS drawing programs easily display and edit PICTįiles, few are able to do anything at all with WMF files. Programs that understand their rendering languages. However, vector graphicsĪre difficult to modify or even display when they are not opened in Altering vector graphics is easy because the shapes within themĬan be ungrouped and edited individually.Their shapes are redrawn to compensate for changes in resolution. This does not happen with vector graphics as If you enlarge aīitmap graphic, it will look jagged. Bitmap graphics are affected by resolution.In general, a bitmap graphic is much larger than a similar vector.For more information about SVG, see:Īs described below, bitmap and vector graphics both have their SVG, or Scalable Vector Graphics, is a language for describing vector These are created with GISĪnd CAD applications as well as drawing programs like FreeHand. Is not possible, however, to embed vector information within a bitmap.Įxamples of vector graphic formats are PICT, EPS, and WMF as well as Vector graphic, which is how vector-bitmap hybrid graphics work. It is even possible to embed a bitmap graphic within a Graphic contains instructions about where to place each of theĬomponents. Image contains information about the color of each pixel, a vector Rather than a grid of pixels, a vector graphic consists of shapes,Ĭurves, lines, and text which together make a picture. Using mathematical formulas describing shapes, colors, and placement. Vector (also known as "object-oriented") graphics are constructed On a computer monitor is also a bitmap, as are the outputs of Examples of bitmap graphic formats include GIF,Īnd PCX as well as bitmap (i.e., screen) fonts. Include more colors photograph-quality images may have Simplest form, bitmaps have only two colors, with each pixel beingĮither black or white. Information here may no longer be accurate, and links may no longer be available or reliable.Ī bitmap (also called "raster") graphic is created from rows ofĭifferent colored pixels that together form an image.
