                       java.lang.String targetMimetype,

Description copied from interface: TransformServiceRegistry

Returns the maximun size (in bytes) of the source content that can be transformed.

Parameters:

sourceMimetype - the mimetype of the source content

targetMimetype - the mimetype of the target

options - the actual name value pairs available that could be passed to the Transform Service.

renditionName - (optional) name for the set of options and target mimetype. If supplied is used to cache results to avoid having to work out if a given transformation is supported a second time. The sourceMimetype and sourceSizeInBytes may still change. In the case of ACS this is the rendition name.

Returns:

the maximum size (in bytes) of the source content that can be transformed. If -1 there is no limit, but if 0 the transform is not supported.
