Changing color for transparent is especially useful if the subject needs to be clearly visible in the website background, or when several images need to be layered on top of each other, or when something needs to be removed or hidden in a picture. Making a certain color transparent means that the color will be the same as the background. ImageConverter Plus allows changing any image color for transparent. This can be achieved by regular means or via command-line. Transparency is not so easy to achieve though. If you want to change a certain color for transparent you should note that even one and the same color may contain several color variations, so blue is not necessarily universally blue – it may be lighter or darker in some areas. In case you would like to change color gradations for transparent, choose “tolerance” option. You should also note that not every image format supports transparency, so your choice will be limited to PNG, GIF, TGA, BMP, TIFF, MNG, and PSD images.
