svg SVG or Scalable Vector Graphic File is a graphical format for images which are bi-dimensional and XML-based providing support to animations and various interactive elements. The SVG file format was developed with the open standards created in 1999 by the W3C (Worldwide Web Consortium). Adobe Corporation held the significant role towards the development of this file format, and it is considered to be the industry standard for viewing vector graphics on web networks. SVG images can be created, edited, and recreated in any of the text editing tools and drawing or illustration software. Additionally, SVG can be compressed, searched, scripted, and indexed.
sgi A .sgi extension file saves images in the original Silicon Graphics Image format. These files are originated from the library of SGI images that were there on every Silicon Graphics machine. SGI files are also referred to as RGB, IRIS or Irix RGB., .sgi image files can be saved in 8-bit color, 16-bit or 32-bit color. GIMP has the compatibility to read and write .sgi extension files and also has a dialog box that pops up to help select the compression type. The preferred compression is RLE and while it reduces the file size, it is advisable to check once it is done to ensure that the file size is indeed reduced as sometimes the size is more than the actual file size.
