Tag information |
- class ExifKey
Bases:
KeyConcrete keys for Exif metadata and access to Exif tag reference data.
- clone()
Return an auto-pointer to a copy of itself (deep copy). The caller owns this copy and the auto-pointer ensures that it will be deleted.
- defaultTypeId()
Return the default type id for this tag.
- familyName()
Return an identifier for the type of metadata (the first part of the key)
- groupName()
Return the name of the group (the second part of the key)
- idx()
Return the index (unique id of this key within the original Exif data, 0 if not set)
- key()
Return the key of the metadatum as a string. The key is of the form ‘familyName.groupName.tagName’. Note however that the key is not necessarily unique, e.g., an ExifData may contain multiple metadata with the same key.
- setIdx()
Set the index.
- tag()
Return the tag number
- tagDesc()
Return a description for the tag
- tagLabel()
Return a label for the tag
- tagName()
Return the name of the tag (which is also the third part of the key)
- class ExifTags
Bases:
SwigPyObjectAccess to Exif group and tag lists and misc. tag reference methods, implemented as a static class.
- static defaultCount()
Return the default number of components (not bytes!) key has. (0=any, -1=count not known)
- static groupList()
Return read-only list of built-in groups
- static ifdName()
Return the name of the IFD for the group.
- static isExifGroup()
Return true if groupName is a TIFF or Exif IFD, else false. This is used to differentiate between standard Exif IFDs and IFDs associated with the makernote.
- static isMakerGroup()
Return true if groupName is a makernote group.
- static sectionName()
Return the name of the section for an Exif key.
- static tagList()
Return read-only list of built-in groupName tags.
- class GroupInfo
Bases:
SwigPyObjectThe details of an Exif group. Groups include IFDs and binary arrays.
- groupName_
Group name, unique for each group.
- ifdId_
IFD id
- ifdName_
IFD name
- items()
Get structure members.
- keys()
Get structure member names.
- tagList_
Tag list
- class IfdId
Bases:
IntEnumType to specify the IFD to which a metadata belongs.
Maker note IFDs have been omitted from this enum.
