An extension that allows LV2 plugins to request a resize of an output +port.

+ +

Any host which supports this extension must pass an LV2_Feature to the +plugin's instantiate method with URI http://lv2plug.in/ns/ext/resize-port and a +pointer to a LV2_Resize_Port_Feature structure. This structure provides a +resize_port function which plugins may use to resize output port buffers as +necessary.

+ +

This extension also defines several predicates useful for describing the +amount of space required for a particular port buffer.

This may be used for +any ports, but is generally most useful to indicate an output port must +be at least as large as some input port (because it will copy from it). +If a port is asLargeAs several ports, it is asLargeAs the largest such port +(not the sum of those ports' sizes). + +The host guarantees that whenever an ObjectPort's run method is called, +any output O that is obj:asLargeAs an input I is connected to a buffer large +enough to copy I, or NULL if the port is lv2:connectionOptional. +""" . + +rsz:minimumSize a rdf:Property ; + rdfs:domain lv2:Port ; + rdfs:range lv2:Symbol ; + rdfs:label "minimum size" ; + rdfs:comment """ +Indicates that a port requires a buffer at least this large, in bytes. +Any host that supports the resize-port feature MUST connect any port with a +minimumSize specified to a buffer at least as large as the value given for +this property.
