Raster Coordinate Reference Systems (CRS) Vector Coordinate Reference Systems (CRS) Setting up Python for Spatial on Mac, Windows, and LinuxĢ - Nature of Coordinate Systems in Python Vector graphics are not appropriate for complex images (e.g.PyGIS - Open Source Spatial Programming & Remote Sensing.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.
