An essential technique you need to know about when you work with digital images is the use of transparency. Transparency allows you to cut out certain parts of an image to let what is underneath show through. In this video, author Richard Harrington explains what transparency is, how it is saved in a digital image, and how it can be used.
- You just saw an example of transparency in a graphic…and this is a very common technique that's essential.…Now there are some rudimentary tools inside of Power Point…and Microsoft Word to add transparency data,…but they're not as good as files that come with it built in.…Transparency is going to allow you to store different…types of pixels within the image.…The transparency can be stored within the file formats.…Now, something that is transparent is completely invisible.…
Usually only part of a graphic…is going to be fully transparent.…For example, maybe the area around a logo.…Partial transparency can also be used to create…a translucent effect and you can do this within Office…documents as well by adjusting the transparency settings.…Not all applications will recognize or handle transparency…data correctly however.…This generally works by either having a specific color…that's set to transparent or by using an…embedded alpha channel.…
In this case, I've taken a graphic that has partial…transparency and you see as I animate that around the slide…
