XfaBStrHelpersAvailable - TPdf

Component: TPdf · Unit: PDFium

Read-only flag — True when XFA BSTR helper exports are present in the loaded PDFium DLL

Syntax

function XfaBStrHelpersAvailable: Boolean;

Description

Returns True when XFA BSTR helper exports are present in the loaded PDFium DLL

XFA support requires a special PDFium build with FPDFXFA_* exports; without it, XFA documents render as the static fallback only

Class function; checks the DLL for the symbols at runtime

Remarks

Treat the value as immutable for the lifetime of the open document — reopening the file or changing pages may yield a different result
Surface this value in your UI to drive feature toggles (for example, disable accessibility export when IsTagged is False).
All scalar boolean / type properties on TPdf are inexpensive O(1) reads

Example

if Pdf1.Active and Pdf1.XfaBStrHelpersAvailable then
Memo1.Lines.Add('XfaBStrHelpersAvailable = True')
else
Memo1.Lines.Add('XfaBStrHelpersAvailable = False');
