Transparencies
March 30, 2000
Get some interesting effects with transparency. You'll have to be
precise here or you'll get some really odd effects... interesting
perhaps, but not what you wanted or expected. The most common
mistake when making an image that will have a transparent
background is to make it on the wrong color background.
For best results, match the background color of your web page as
closely as possible. This is especially important if you plan
to add a drop shadow to any part of your image.
Compare the two banner below.
The bottom banner is an example of what happens when you
save a banner with one transparent color and later try to display
it on a webpage with a different background color.
Use transparency to make your text appear to drop off of the
edge of the banner. This is a pretty cool effect, and easy to
do.
Start with a "banner sized" canvas, say 400 x 60 pixels. With
the Selection tool draw out an area smaller than your canvas and
fill it with the color, texture, photo of your choice. Add your
text as a selection, positioning it partly on and partly off of
your previously selected/filled area. The secret is in making
your background color transparent. For best results, don't use
the background color elsewhere in the banner or you'll find that
area becomes transparent as well.
On the other hand, you may want other areas of your image to
be transparent... the text, for example.
This banner adds a twist:
the text is done with a cutout while the shaped background
has a drop shadow. Is the text sitting on the shape or is it
cut out of it?
No one can tell you exactly how to create an award winning
banner, there's a lot of trial and error involved. Hopefully
the examples and tips in this article will give you a good starting
point.
