Method Detail

copy

public DeferredIconImpl<T> copy()

Description copied from interface: CopyableIcon

Returns a copy of this icon.

The copy should be a new instance, it should preserve the original size and should paint equal to the original bitmap. The subtype of the new icon is up to an implementor. It may or may not be equal the original subtype.

Specified by:

copy in interface CopyableIcon

Specified by:

copy in class JBCachingScalableIcon<DeferredIconImpl<T>>

scale

public DeferredIconImpl<T> scale(float scale)

Description copied from interface: ScalableIcon

Creates and returns a scaled instance of the icon. The icon is scaled relative to its origin, that is scale(1f) will return the icon in its original scale. To scale this instance by n times: scale(n * getScale()). Note that the methods Icon.getIconWidth() and Icon.getIconHeight() should return the scaled size of the icon.

Specified by:

Overrides:

scale in class JBCachingScalableIcon<DeferredIconImpl<T>>

Parameters:

scale - scale

Returns:

a new scaled copy of this icon, or the cached instance of the provided scale
