In graphics color information is saved in three channels: red, green, and blue. There is one more channel that is invisible – called the “alpha channel”. Alpha channel in graphics is a channel, or a mask – it specifies how the colors should be merged to achieve transparency. Transparency can be of different levels – a certain part of each pixel’s information is reserved for transparency. One can apply different alpha channels to the same image isolating different portions making each image look slightly different. Transparent images are useful when you are not sure of the page background color on which your image will be displayed, or you intend to display your image in front of a complex background rather than a single background color. By adding the alpha channel to an image you control the transparency of the red, green and blue channels. Different parts of an image can have different levels of transparency depending on how much you want the background to show through. A few of the standard image formats (TIFF and PNG, for example) provide support for an embedded alpha channel which represents up to 256 levels of transparency. Images with an embedded alpha channel can be used on other applications while retaining transparency as long as the other application also supports alpha channels. But if that other application cannot accept all the image format specifications there comes a problem working with the alpha channel. ImageConverter Plus can allow viewing images with alpha channel and keeping it when converting images or ignoring it when necessary. Among other image formats supporting transparency are BMP, DDS, DICOM, EXR, PSP, PSD, JNG, TGA, etc. The main advantage of ImageConverter Plus is to support transparency according to each format’s unique specifications.
