Why Do You Need to Use PNG File Format in Your Website Creation?
The advantages of including PNG image format in web designing over various other image formats like GIF and JPEG; the file format works well if you need to make better and wonderful icons that will entice your visitorsThe PNG image format was introduced some time ago; it was put forth in the market in 1995/96 to cover the drawbacks of the popular GIF file type. However, it did not make an impression because the early browsers were unable to support the progressive features of PNG so internet designers and developers were forced to include it in their designs restrictedly. One of the major blocks faced by the format was Microsoft's flagship product, Internet Explorer which was by far the most famous browsers of that period; IE had limited space for PNG support consequently the format could only be made use of to a bare minimum. Then, matters changed when IE7 was brought out; this latest offering from Microsoft has helped in increasing the utility of PNGs. So here is a look at three reasons why PNG is one of the most useful image formats around today:
You can get see through images or a feature called alpha transparency: When you analyze the features of GIF and PNG, it will become apparent that A definitive difference in the two formats is that you can only save a particular color transparently through the use of GIF this simply means that the color can be used whether opaque or transparent with no other color in betweenbut when you use PNG, you get a specific advantage; because the format can be used to produce semi transparency. This feature gives you the ability to save a PNG image with a soft drop shadow and then float it against any background. The Image can also be used as a gradient background or water mark. The file type lets you incorporate the smooth fading of hues from fully opaque to absolutely transparent, exposing the webpage underneath
They look fabulous: Apart from the fact, that you get amazing flexibility wit PNG images; there are numerous other advantages to including this format. For example, if you make use of the JPG Format, you lose a part of the information from the original file whenever you save the file, so in time, you will notice a noticeable downgrade in the appearance of the images. Even if, this concern has been resolved in in the file type and it is possible to store the files without losing any information, GIF only allows for a limited 256 color palette, which makes it quite ineffective if you want to store a picture. However, with PNG, you can get the most desired features of the two file types; you will be provided a complete color display like the one used in JPEG images and it also supports managed color palette a la GIF files. Another advantage is that the storage of the file is without loss so the photograph stays put even if you save the file several times.
PNG is self optimizing: One of the hurdles that web programmers need to handle frequently is the fact that the brightness and the contrast ratio of the screen has to be regulated to see the the display correctly; this happens due to the difference in the Gamma setting used for the different monitors. Gamma is a method that helps to scatter the luminance across the monitor display. However, various operating systems use varying Gamma settings. Hence, an image that is color corrected specifically for Windows may not look right on a Mac. Here again, in this scenario the flexible PNG format can prove useful, in PNG, you can store the pictures with with a Gamma correction feature that is innate so regardless of the operating system; the Gamma settings will be automatically adjusted to show a picture with the amazing brightness and contrast.
