Icon sizes: 256x256, 48x48, 32x32, 24x24, 16x16 File formats: ICO, GIF, PNG, BMP Why Should You Use PNG File Format in Your Website Creation?The advantages of incorporating PNG images in web designing over various other file types ;for instance, GIF and JPEG; the file type works well if you need to make better and efficient web graphics that will entice your visitorsThe PNG file format was introduced quite a while back; it was brought out for consumers in 1995/96 to cover the drawbacks of the traditional GIF file type. However, it did not make an impression because the the browsers of the time could not offer support to the state of the art offerings of PNG so website designers and developers were forced to use it sparingly. One of the primary hindrances faced by the format was Microsoft Internet Explorer which was one of the most popular browsers of the time; IE had limited provision for PNG support consequently the format could only be made use of to a bare minimum. But, things went through a change after the availability of IE7; this new product from Microsoft has proved immensely useful in increasing increasing the usability of PNGs. So here is a look at three reasons why PNG is one of the most innovative image formats to be introduced so far: It is possible to create transparent images or a feature called alpha transparency: When you pitch GIF against PNG, you will see that a very distinct advantage with PNG is that you you will be restricted to saving a particular color as transparent in 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 distinct 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. You can also use the image as a watermark or a gradient background. The format lets you incorporate the gradual fading of hues from fully opaque to absolutely transparent, exposing the webpage underneath They look fabulous: It is a well known fact that PNG images give you extreme flexibility also; there are several other advantages to including this format. For instance, if you choose a JPG image, you lose a portion of the details from the original file whenever you save the file, so after a while, you will be able to see a noticeable downgrade in the quality of the media. Even though, this concern has been solved in in the file type and you can save the files without compromising any information, GIF has a limited color palette of 256, which makes it quite useless if you want to store a photograph. On the other hand, with PNG, you will get the perfect features of the image formats; you will be provided a full color display like with JPEG images and it also provides managed color palette like GIF files. Also the storage of the picture is without loss so the image does not change regardless of how many time you save it. PNG allows for self optimization: A major concern that web programmers have to tackle on a daily basis is the issue where the contrast and brightness of the commuter screen has to be regulated to see the images appropriately; this problem occurs due to various Gamma setting used in monitors from different vendors. Gamma setting is a method used to scatter the luminance across the screen. However, various operating systems use varying Gamma settings. So, an image that is color corrected specifically for Windows may appear abnormal in Mac. Once again, in this case the versatile PNG image type can help you out, in PNG, you can save the images with with a Gamma correction feature that is innate so despite the differences in operating systems; the Gamma settings will be automatically adjusted to show a file with the amazing brightness and contrast.
