Compositing template. Allows specifying a compositing template located in a catalog other than the main catalog.
template must be an image catalog entry with the template body contained in catalog::Modifier.
When template= is present, the object specified in the request path will not be applied as the source for layer 0, but can be referenced as a src= or mask= anywhere in the template by using the predefined path variable $object$ as a src= value. catalog::Modifier of the object specified in the request path is only applied in connection with the substitution of $object$ within the template, while catalog::PostModifier is always applied.
Layer 0 is defined in the template body and may be an image, solid color, text, or nested or embedded request layer.
catalog:PostModifier of object is ignored when object is used with template=.
Request attribute. Applies regardless of the current layer setting.
See the examples in Templates.
