def Load(self,fileName,pageNumber,dpiX,dpiY):
fileName
File containing the XML data of the annotations to be loaded. This value must not be null.
pageNumber
1-based page number to load.
dpiX
The horizontal resolution of the image.
dpiY
The vertical resolution of the image.
A new AnnContainer object containing all the objects loaded from fileName.
This method is designed to load annotation files that were saved with LEADTOOLS SDK prior to version 15. These files did not save the resolution of the image and the user has to manually pass these values before loading. Pass the original resolution used when the annotation file was created to dpiX and dpiY.
If fileName contains a container with the same page as pageNumber, then this page will be loaded. If the value of pageNumber is 0, the first page is loaded. Otherwise, this method will return null.
The DeserializeOptions property can contain optional options and events to use during loading of annotations data.
For more information, refer to Annotation Files.
