However, the major downside to raster images is that the more the images are manipulated after creation, the more the quality declines. The advantage of raster graphics is that at high resolutions (lots of pixels in a small area) you can have very fine control over color and shape raster images can contain millions of colors and look very realistic. They are made up of pixels, which is to say a grid of colored rectangular dots. Raster images are the default output of everything from digital cameras to most graphics editing software like Paint or Paintbrush. Common examples are JPG, PNG, GIF, TIFF or BMP. Raster or bitmap images are a majority of the digital images you generally encounter. However, there are two main types of images: There are numerous other vector formats: CDR is the CorelDRAW native format and XAR is the Xara Xtreme native format, to name a couple.There are many image creation and manipulation software programs. 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 There is a large number of different bitmap formats.
