The bitmap image file format or bmp file for short, is a raster graphics image file. It uses a dot matrix data structure to represent pixelated points of color and to store digital image information. The format optionally supports compression and has wide cross platform support on all the major computer operating systems. Because bmp files are raster graphics files, image resolution is constrained meaning images in this format will not scale without loss in quality. This is in contrast to vector graphics images that can scale to arbitrary resolutions.
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 BMP to SGI conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload BMP 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.
Because bmp files can be uncompressed, it is capable of supporting larger file sizes and thus higher resolution and higher quality images. This capability makes bmp files inappropriate for digital distribution via webpages or through bandwidth limited networks. Pixels in a bitmap support deferent color depths from 1 bit of either black or white, to grayscale which is 8 bits, to finally 24 bit RGB giving a possible 16777216 possible colors. Color depth can go as high as 32 bits however this is rarely encountered or needed in practice.
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.
Upload your image file in the BMP format from your device, Dropbox, or Google Drive.
Select SGI as the output format and click Convert. Adjust optional settings if needed.
Download the converted image file. Each file stays available for up to 5 downloads.
