Member Function Documentation

◆ GetRootElement()

def fsdk.LRContext.GetRootElement ( )

Get the root element of structure tree.

Please ensure current context object has been parsed successfully before calling this function; otherwise, no valid root structure element can be retrieved.

Returns
Root element.

◆ IsEmpty()

def fsdk.LRContext.IsEmpty ( )

Check whether current object is empty or not.

When the current object is empty, that means current object is useless.

Returns
true means current object is empty, while false means not.

◆ StartParse()

def fsdk.LRContext.StartParse (   pause)

Start to parse layout recognition for related PDF page.

It may take a long time to do parsing, so Foxit PDF SDK uses a progressive process to do this. If there is any error occurs in parsing progress, this function will throw exception. Please refer to class fsdk and values starting from fsdk.E_ErrFile .

Parameters
[in]pausePause callback object which decides if the parsing process needs to be paused. This can be null which means not to pause during the parsing process. If this is not null, it should be a valid pause object implemented by user. Default value: null.
Returns
A progressive object. Please check the rate of current progress by function fsdk.Progressive.GetRateOfProgress . If the rate is not 100 yet, call function fsdk.Progressive.Continue to continue the progress until the progress is finished.
