Overview |
GIF is an image format which is known worldwide and it is used as a second option after JPEG. It offers high portability between OS(Operating Systems) and applications. Each picture can support up to 8 bits per pixel, as a resultant, it enables an image to have a separate palette of up to 256 distinct colours that are taken from the 24-bit RGB colour space. Furthermore, it is commonly used for web graphics, logos with solid colour and also for animated images. These files are saved as ‘animated GIFs' and it displays general animations on websites. Besides this, this format has the capability to blend varied colour backgrounds due to the presence of transparent pixels. It should be noted that pixels should be either fully transparent or opaque so that it doesn’t result in the faded picture. |
Technical description |
GIF is an inadequate format for colour photographs due to palette limitations. It enables an independent palette of up to 256 colors for a solo frame. These files are compressed using a lossless data compression algorithm known as LZW( Lempel-Ziv-Welch) and this algorithm was created by Abraham Lempel, Jacob Ziv and Terry Welch. It removes the unwanted colours that are not in use to compress raster data. The maximum limit which is permitted for colours is 256 and the minimum is 2 (black and white). Apart from this, it has a fixed-length header which gives the version and pixel dimensions are provided by the ‘logical screen' descriptor. |

Overview |
PDF is a format which stores documents that can include text with distinct fonts and images. The text that is present in it is of static or fixed format which is just like an image and it remains exactly the same even if we open this file using other programs, hardware and different operating systems. That is why it is recommended to convert the file into this format before printing or transferring, so, that the arrangement of the lines remains the same. Thereby, the output that is generated is always a printer-ready. These files are editable and can be amended using various editors. Several files can also be merged and compressed online. It does not only support Adobe Acrobat Reader but also other similar programs. These files can be sent, saved and viewed easily using phones, computers or tablets. |

There is a vast horizon of features that are available in PDFs. The content in it can have logical structuring elements, annotations, rich media, digital signatures and 3D computer graphics data (U3D); etc. Although, it is a 7-bit ASCII (American Standard Code for information interchange), yet, it may contain binary content as well. This file starts with a header which indicates how bits are used to encode information, succeeded by the version of the format. Furthermore, it is a subset of COS i.e. Carousel object structure, which expands to eight primary objects named as- Boolean Values (true or false), numbers, strings, names, arrays, dictionaries, streams and the null object. These files can also be password protected for security reasons. |
