The TIFF format was developed by the company Aldus in 1986, which was later acquired by Adobe systems who now own the rights on the format specification. TIFF, which refers to the Tagged Image File Format, is a raster graphics file format popularly used in desktop publishing and print. Its initial development goal was to create an alternative and cross platform format that would replace the numerous proprietary formats used by scanners developed in the 80's. Later revisions, after Adobe took over the development of the format, saw the TIFF format become extensible to adapt with growing and changing needs of the graphics industry. TIFF supports high color depth and is well suited to OCR applications, scanning, image editing and authoring as well as word processing. The format uses the filename extension .tiff for files stored in the format.
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.
FreeFileConvert uses tuned encoding for TIFF to SGI conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload TIFF files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized SGI results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent SGI audio with dependable progress tracking.
The original version of the TIFF format had no support for compression but by the 5th release of the format, LZW compression (a lossless compression algorithm) was supported. However, the format can also be used to store data in a lossless format without compression. This cannot be done though if the TIFF file is acting as an archive for JPEG data which is inherently lossy. TIFF supports monochrome, grayscale, palette color, and full true color.
SGI is a generic raster image file format that stores black and white, gray scale and color images. Images in the SGI format are generic bitmap images that have the capacity to store 8 to 32 bits per pixel. The file size of the images can be compressed with the Run-length encoding (RLE) technique. The .sgi extension files begin with a 512 byte header that is fixed and is followed by the pixel data. There is a scan-line table in case of compressed images with the compressed pixel data following the table. The scan-line offset table indicates the start of every scan line in the data of a compressed image. Lots of bit planes, alpha channel data and / or color maps may be included in the files with .sgi extension. Contrary to the top-down order followed by other formats, the pixel data in .sgi extension file follows the bottom-up order.
