Function Reference
Page 517 of 766
LoadFDFData
Syntax:
LBOOL pdfLoadFDFData(
const PPDF* IPDF,
// Instance pointer
const char* FileName, // File path of the FDF file
const char* Password, // Defined for future use, should be NULL
UI32 Flags)
// Defined for future use, should be 0
The function loads form data from a FDF file (Forms Data Format). The corresponding form must be
imported before the function can be used. See ImportPDFFile() for further information.
Return values:
If the function succeeds the return value is 1. If the function fails the return value is 0.
LoadFDFDataEx
Syntax:
LBOOL pdfLoadFDFDataEx(
const PPDF* IPDF,
// Instance pointer
const void* Buffer,
// FDF file buffer
UI32 BufSize,
// Buffer size if bytes
const char* Password, // Defined for future use, should be NULL
UI32 Flags)
// Defined for future use, should be 0
The function loads form data from a FDF file (Forms Data Format) like LoadFDFData but it accepts a
file buffer instead. The corresponding form must be imported before the function can be used. See
ImportPDFFile() for further information.
Return values:
If the function succeeds the return value is 1. If the function fails the return value is 0.
LoadLayerConfig
Syntax:
LBOOL pdfLoadLayerConfig(
const PPDF* IPDF, // Instance pointer
SI32 Index)
// See description
The function loads the specified layer configuration. A PDF file that contains layers (Optional
Content Groups in PDF syntax) contains usually at least a default configuration dictionary. This
configuration is loaded by default when the visibility state of a layer or optional content group must
be determined, e.g. when rendering a page.
Use this function to load another configuration if available. To determine the number of available
configurations call GetLayerConfigCount().
