The term “transparency” may be applied onto various topics: politics, finances, water, ice, air, etc. The term carries some positive impact and desire to improve the subject under discussion. Making things transparent we make them more open, more accessible and easier to understand. When we apply transparency on digital images, this may be useful when the background color is not known, or for the website design. It generally improves the impression of the image. An image with a transparent background might be placed against a website background. This gives a web designer flexibility in placing the image on the page, and it can help make the file size smaller versus creating a large background file with the image included. Not all image file formats support transparency, so the two file types to use are GIF or PNG. GIF is most widely used, though the drawback of this format is that it reduces the number of colors to no more than 256, so high quality photographs will not be appropriate for this format and may look distorted. GIF does not support partial transparency – you can make the whole image transparent, which will prevent you from reflecting shadows and color gradations. PNG was developed to replace GIF. It supports partial transparency by means of alpha channel. The only problem one may come across is the fact that older browsers may fail to support this format. Replacement of color for transparent can be performed via “replace color” operation of ImageConverter Plus. Besides, you can convert images saved in different formats to GIF and PNG.
