Gradient Fill Tool

Whereas solid fills use a single color, all gradient fills in PhotoPlus utilize at least

two "key" colors, with a spread of hues in between each key color, creating a

"spectrum" effect. You can fine-tune the actual spread of color between pairs of

key colors. Likewise, a gradient fill in PhotoPlus can have either solid

transparency—one level of opacity, like 50% or 100%, across its entire range—

or variable transparency, with at least two "key" opacity levels and a spread of

values in between. (Remember that opacity is simply an inverse way of

expressing transparency.)

The

Gradient Fill Tool lets you apply variable color and/or transparency

fills directly to a layer. Five types of fill (Solid, Linear, Radial, Conical, and

Square) are available. Technically, a Solid fill is different (it uses just one color)

but in practice you can also achieve a unicolor effect using a gradient fill.

Solid Linear Radial Conical Square

Applying a gradient fill on any kind of layer entails selecting one of the fill types,

editing the fill colors and/or transparency in a Gradient dialog, then applying the

fill. However, gradient fills behave differently depending on the kind of layer

you're working on.

On standard and Background layers, the tool creates a

"spectrum" effect, filling the active layer or selection

with colors spreading between the key colors in the

selected gradient fill. The fill is applied rather like a coat

of spray paint over existing pixels on the layer; color

and transparency properties in the fill gradient interact

with the existing pixels to produce new values. In other

words, once you've applied the fill, you can't go back

and edit it (except by undoing it and trying again).
