Digital file formats

In case of the functioning of digital cameras, it is immensely significant to remember that unlike the analog cameras, they are not provided with films for storage of pictures and in digital cameras the memory cards act as the storage device. Once the images have been captured the pictures need to be transferred to the computer via the USB port supplied with the camera. The digital camera supports certain image file formats and the computers too support certain specific image file formats and these formatting are very significant in case of further image editing and processing with the use of graphics and other software applications as well. Therefore it can be concluded without a trace of doubt that the image file formats are absolutely essential for arranging and storage of image files. These image files are comprised of various pixels which may be organized in the form of a rectangular grid or even as geometrical figures and the sizes of these files are represented in the form of bytes. The image resolution is also greatly dependent on the pixels and there are various methods like image editing, compression and processing which make use of these file formats.

There are various kind of image file formats and can be broadly divided into the vector and the raster formats. Vector file formats make use of geometrical structures like polygons and curves and they comprise of 3D image files which allow texture mapping of pixel data. There is also the SVG or Scalable Vector Graphics is a vector file formatting designed specifically for the web. The raster graphic file formats store images in the form of bitmaps and includes JPEG or Joint Photographic Experts Group, the RAW which refers to raw image formats, PNG or Portable Network Graphics, TIFF or Tagged Image File Formats, BMP files or bitmap image formats and GIF or Graphic Interchange Formats.
