Description

This interface is implemented by elements that are able to do XMP serialization. Examples for such elements are jifmux and qtmux.

Applications can use this interface to configure which XMP schemas should be used when serializing tags into XMP. Schemas are represented by their names, a full list of the supported schemas can be obtained from tagXmpListSchemas. By default, all schemas are used.

Methods

Overloaded methods

addAllSchemas

tagXmpWriterAddAllSchemas Source #

Arguments

:: (HasCallStack, MonadIO m, IsTagXmpWriter a)
=> a	`config`: a `TagXmpWriter`
-> m ()

Adds all available XMP schemas to the configuration. Meaning that all will be used.

addSchema

tagXmpWriterAddSchema Source #

Arguments

:: (HasCallStack, MonadIO m, IsTagXmpWriter a)
=> a	`config`: a `TagXmpWriter`
-> Text	`schema`: the schema to be added
-> m ()

Adds schema to the list schemas

hasSchema

tagXmpWriterHasSchema Source #

Arguments

:: (HasCallStack, MonadIO m, IsTagXmpWriter a)
=> a	`config`: a `TagXmpWriter`
-> Text	`schema`: the schema to test
-> m Bool	Returns: `True` if it is going to be used

Checks if schema is going to be used

removeAllSchemas

tagXmpWriterRemoveAllSchemas Source #

Arguments

:: (HasCallStack, MonadIO m, IsTagXmpWriter a)
=> a	`config`: a `TagXmpWriter`
-> m ()

Removes all schemas from the list of schemas to use. Meaning that no XMP will be generated.

removeSchema

tagXmpWriterRemoveSchema Source #

Arguments

:: (HasCallStack, MonadIO m, IsTagXmpWriter a)
=> a	`config`: a `TagXmpWriter`
-> Text	`schema`: the schema to remove
-> m ()

Removes a schema from the list of schemas to use. Nothing is done if the schema wasn't in the list
