Why Do You Need to Use PNG Images in Your Web Design?
The pros of incorporating PNG image format in website designing over other image formats such as GIF and JPEG; the file format can be used to make good and wonderful icons that will prove alluring to your consumersThe PNG file type was introduced some time ago; it was put forth in the market in 1995/96 to make up for the shortcomings of the popular GIF image format. However, it did not make an impression because the early browsers could not offer support to the advanced attributes of PNG so internet designers and makers had to incorporate it restrictedly. One of the main hurdles that marred the features of PNG was with Microsoft Internet Explorer which was one of the most popular browsers of that period; IE had little or no provision for PNG support which meant that the format could only be made use of in the most restricted way. Then, things metamorphosed with the introduction of IE7; this new offering from Microsoft has proved immensely useful in increasing increasing the usability of PNGs. So lets take a look at three reasons why PNG is one of the best image formats around today:
You can get transparent images or a property known as alpha transparency: When you pitch GIF against PNG, it will become apparent that A definitive difference in the two formats is that you can only save any odd color transparently through the use of GIF this equates to the fact that the color can be transformed whether opaque or transparent with just transparency in between; however, with PNG, you get a serious benefit; because the format supports semi transparent pixels. This simply means that you can save a PNG image with a soft drop shadow and then use it against a background of your choice. The Image can also be used as a background with gradient or a water mark. The format gives you the option to use the smooth fading of shades from entirely opaque to see through, so that you can see the webpage below
They look fantastic: It is a well known fact that PNG images give you extreme flexibility also; there are numerous other benefits to incorporating this format. For example, if you make use of the JPG Format, you lose a portion of the information from the original file each time you save the file, so in time, you will be able to view a conspicuous downgrade in the appearance of the pictures. Even though, this concern has now been sorted in in the file type and you can store the images without compromising any details, GIF has a highly restrictive 256 color palette, which renders it quite ineffective if you have to store a photograph. On the other hand, when you use PNG, you will get the perfect attributes of both these formats; you will be provided a complete color display like with JPEG file type and it also offers managed color palette a la GIF files. Also the compression of the file is lossless so the picture stays put even if you save the file several times.
PNG allows for self optimization: A major concern that web designers face frequently is the anomaly due to which the contrast and the brightness of the monitor has to be changed to see the images properly; this problem occurs due to various Gamma setting used in monitors from different vendors. Gamma setting is a method incorporated to scatter the brightness across the display surface. However, diverse operating systems use varying Gamma settings. Therefore, an image that is color corrected for Windows may not look right on a Mac. Here again, in this case the versatile PNG image type can prove useful, in PNG, you can store the files with a built in Gamma correction so regardless of the operating system; the Gamma settings will be automatically adjusted to show a picture with the impressive ratios of contrast as well as brightness.
