Character string containing the name of the file to load. |
phObject |
Address of the variable to be updated with the handle to the outermost (root) container object from the file. |
pLoadOptions |
Pointer to optional extended load options. Pass NULL to use the default load options. |
Returns
SUCCESS |
The function was successful. |

Comments
Before calling this function, you must declare a variable of data type HANNOBJECT. Then, pass the address of the variable in the phObject parameter. This function will update the variable with the handle of the outermost (root) object from the file (typically a container object). When this variable is no longer needed, you must free the allocated memory by calling L_AnnDestroy for this variable.
L_AnnLoad will load annotations stored in LEAD files. It will also look for annotations stored as a Wang compatible TIFF tag in TIF files, and load those annotations.
The page number used when loading annotations is obtained from the LOADFILEOPTION structure.
For more information about loading and pasting automated annotations, refer to Loading and Pasting Automated Annotations.

Example
For complete sample code, refer to the ANNOTATE example. This example loads annotations from a file and redraws the image to display the loaded annotations.
