public void saveLayer(OutputStream stream, AnnLayer layer, AnnFormat format, int savePageNumber)
def SaveLayer(self,stream,layer,format,savePageNumber):
stream
Stream containing the XML data of the annotations to be loaded. This value must not be null.
layer
The AnnLayer to be saved. This value must not be null.
format
Must be AnnFormat.Annotations.
savePageNumber
Page number to put inside the data.
This method works the same and produces the same annotation file format as AnnCodecs.Save(Stream stream, AnnContainer container, AnnFormat format, int pageSaveNumber) does, except it saves only the objects inside the individual layer specified instead of all the objects in the container.
Note that "load layer" functionality is not required by AnnCodecs. An AnnLayer cannot exist by itself without an annotation container, hence any of the load functions that accept a container parameter can be used to load the file saved by this function.
If stream is not an empty stream, then it must contain valid LEADTOOLS Annotations data previously saved. This method inserts or replaces the page specified in savePageNumber.
If stream is a new stream, then this method creates new LEADTOOLS Annotations data and saves it.
If the value of savePageNumber is 0, the default value of 1 is used. Otherwise, the page number used when saving is savePageNumber.
LEADTOOLS supports saving multiple containers in the same file, each having a unique page number. Use Load with a page number to load the desired page.
The SerializeOptions property can contain optional options and events that can be used when saving annotation data.
For more information, refer to Annotation Files.
