![]() The same is not true for raster images, since the color information of these images is stretched when scaled. That means images don't lose quality when they're scaled up or down, since the color polygons in a vector image will always maintain their shape. The geometry which comprises vector images is formulaic, making them resolution-independent. Since vector images use dynamic color sections instead of static squares, they provide perfect lines and crisp colors. Vector graphics convey color using scalable color polygons. Raster images use square pixels (bits of color) to convey an image. Most images found online are raster images. What Is a Vector Image?Ī vector image is a scalable image made up of values rather than pixels. Here's how to convert an image to a vector using Adobe Illustrator. Bit map or Raster images are common images created with pixel-based programs or captured with a camera or scanner. It's a quick and simple process and produces excellent results. When you've got a raster graphic that's too small for your needs, the solution is to convert the image to a vector, and you can do this in Adobe Illustrator. They're usually less detailed, but you can make them as big as you like without losing anything. There are numerous other vector formats: CDR is the CorelDRAW native format and XAR is the Xara Xtreme native format, to name a couple.A vector image is made from lines and shapes. Line+spline as well as line only output modes. Some programs have difficulty reading DXF files with splines (curves), so the Desktop Edition supports The AI format is fairly widely supported, but is less ubiquitous than the EPS format, and most programs that read AI can also read EPS.Ī CAD format from Autodesk, used by CAD tools from many different vendors. The native format of Adobe Illustrator is the AI format (Adobe Illustrator Artwork), a modified version of the older EPS format. Support for reading and editing PDF files is much more limited. Those tools work with any program that is able to print. (third party tools that perform the same task are also for sale). Further information on the SVG format may be found on the official SVG website.Īdobe's PDF format (Portable Document Format) is very widely used as a general purpose platform-independent document format.Īnd while it is not exclusively used as such, it is also a very good vector image format.Īdobe gives away the Acrobat PDF reader, but sells the tools required to create PDF files Inkscape and recent versions of Adobe IllustratorĪnd CorelDRAW have good support for reading and writing SVG. ![]() The W3C standard vector image format is called SVG (Scalable Vector Graphics). Ghostview can read it very well but does not have any editing capabilities. It is widely supported as an export format, but due to the complexity of the full format specification, not all programs that claim to support EPS are able to import all variants of it.Īdobe Illustrator and recent versions of CorelDRAW have very good support for reading and writing EPS. It is the standard interchange format in the print industry. In any case, all of the variants of BMP should be avoided when possible, as they use little to noĬompression and consequently have unnecessarily large file sizes.Īdobe's EPS format (Encapsulated PostScript) is perhaps the most common vector image format. Most modern image editing tools are able to read both. Own formats, both of which are called BMP. There are actually several BMP formats (BitMaP). Vector Magic recommends using the PNG format when storing logos as bitmaps. ![]() This format is widely supported by web browsers and image viewers/editors. The best of the lossless image formats is called PNG (Portable Network Graphics). They are more suitable for things like logos. These store an exact pixel-by-pixel representation of the image, but require more space. We do not recommend using JPEG files for rasterized vector art, as the compression artifacts substantially degrade the quality of the image near edges. It has excellent compression characteristics and has the nice feature that the user may specify what level of compression they desire, trading off fidelity for file size. One of the most widely-used image formats. They are also commonly used on the web to save bandwidth. They are best suited to photographs and other images where perfect accuracy is not important. ![]() These have smaller file sizes but do not store a perfect copy of the image. Some of the most common are: JPEG, PNG, GIF, BMP, and TIFF.īroadly speaking, they fall into two categories: Lossy formats This tool converts a shapefile to a raster and applies the values in a specified. The process of raster to vector conversion service involves tracing the pixels of the original image to create a vector file that can be scaled to any size. There is a large number of different bitmap formats. To convert a vector to a raster format, QGIS provides the Rasterize tool. ![]()
