Graphic file formats are uniform means of organizing and storing digital images. Graphic files are composed of either pixel or vector data when displayed in a vector graphic display. The pixel that constitute an image are representing as magnitudes of brightness and color. Image file size in Graphic file formats expressed as the number of bytes. When the color depth of image increases the pixel of an image also increases. There are normally two types of file compression such as: Lossless and Lossy compression. Lossless file compression decrease file size without losing image quality. These types of image file compression are required when image quality is valued above file size. In the other hand lossy compression is allow for variable quality compressions as the file size is reduced. Well, there are hundreds of graphics file formats available but the PNG, JPEG and GIF formats are often used to display the images on the internet.
The image compression makes use of the algorithms to decrease size of the file. The high resolution of cameras make large image files, and ranging at hundreds of kilobytes and megabytes, per camera’s resolution as well as image storage format ability. The high resolution cameras record twelve megapixel (1MP=1,000,000 pixels/1 million) images, and more, in the true color. For instance, the image recorded by the 12MP camera; as every pixel makes use of three bytes to record the true color, uncompressed image will occupy 36,000,000bytes of the memory?great amount of the digital storage for an image, given cameras should record as well as store a lot of images to be very practical. If faced with the large file sizes, both in camera and storage disc, the image file formats were been developed to store large images.
