Why Do You Need to Use PNG File Format in Your Web Design?
The advantages of using PNG image format in web designing over various other formats ;for instance, GIF and JPEG; the image format works well if you need to make better and efficient web graphics that will entice your visitorsThe PNG image format was introduced a few years back; it was put forth in the market around 95/96 to make up for the shortcomings of the the common GIF file format. However, it did not make an impression because the the browsers of the time could not offer support to the progressive attributes of PNG so internet designers and creators were compelled to include it in their designs sparingly. One of the major hindrances that marred the features of PNG was with Microsoft's Internet Explorer which was by far the most famous browsers of the time; IE had very little space for PNG support consequently the format could only be used in limited capacity. Then, things went through a change when IE7 was brought out; this fresh offering from Microsoft has aided in increasing the popularity of PNGs. So here is a look at three reasons why PNG is by far the most innovative image formats around today:
You can get see through images or a feature called alpha transparency: When you pitch GIF against PNG, will notice that A definitive difference in the two formats is that you can only save a specific color as transparent in GIF which means that you can get the color regardless of it being opaque or transparent with no other color in betweenbut when you use PNG, you get a serious feature over GIF; because the format is capable of producing semi transparent pixels. This feature gives you the ability to save a PNG file with a soft drop shadow and then use it against a background of your choice. The Image can also be used as a gradient background or water mark. The format lets you incorporate the slow fading of colors from entirely opaque to see through, so that you can see the webpage underneath
They look fabulous: Apart from the fact, that you get amazing flexibility wit PNG images; there are several other advantages to using this format. For instance, if you choose a JPG image, you lose some of the data from the initial image every time you save the file, so after a while, you will be able to see a noticeable downgrade in the finesse of the media. Even if, this concern has now been sorted in GIF and you can store the pictures without compromising any information, GIF only allows for a limited 256 color palette, which imparts it quite useless if you have to store a picture. But, when you use PNG, you will get the most desired attributes of the image formats; you get a complete color display like with JPEG format and it also provides managed color palette as seen in GIF files. Also the storage of the image is lossless so the image does not change regardless of how many time you save it.
PNG allows for self optimization: A serious problem that web programmers face very often is the fact that the contrast and the brightness of the monitor has to be changed to see the images correctly; the issue comes into the picture due to the Gamma settings of different monitors. Gamma setting is a method used to scatter the the light across the monitor display. However, diverse operating systems use a variety of Gamma settings. Hence, an image that is color corrected to suit Windows will seem wrong when seen on Mac. Again, in this scenario the versatile PNG picture format comes to the rescue, in PNG, you can save the images with an inherent Gamma correction feature so despite the differences in operating systems; the Gamma settings will be realigned to display an image with the perfect ratios of contrast as well as brightness.
