Page 361 of 787
Remarks:
The structure TPDFFileSpec contains pointers to the original values of the embedded file. These
values must not be changed or freed in your application.
Return values:
If the function succeeds the return value 1 and the structure TPDFFileSpec is filled with values. If
the function fails the return value is 0.
GetEmbeddedFileCount
Syntax:
SI32 pdfGetEmbeddedFileCount(
const PPDF* IPDF) // Instance pointer
The function returns the number of embedded files available in the PDF file. Note that the number
of embedded files from an external PDF file is available after the PDF file has been imported.
Depending of the used import flags embedded files can be excluded from import. See
SetImportFlags(), or ImportPDFFile() for further information.
GetEmbeddedFileNode
Syntax:
LBOOL pdfGetEmbeddedFileNode(
const IEFN* IEF,
// Pointer of an embedded file node
struct TPDFEmbFileNode* F, // see below
LBOOL Decompress)
// If true, the file will be decompressed
struct TPDFEmbFileNode
{
UI32
StructSize; // Must be set to sizeof(TPDFEmbFileNode).
const char*
Name;
// UTF-8 encoded name. This is usually an ASCII string.
struct TPDFFileSpec EF;
// Embedded file.
IEFN*
NextNode;
// Next node if any.
};
struct TPDFFileSpec
{
char* Buffer;
// Buffer of an embedded file.
UI32 BufSize;
// Buffer size in bytes.
LBOOL Compressed;
// Should be false if Decompress was true.
void* ColItem;
// Pointer to user defined collection item.
char* Name;
// Name of the file specification in the name tree.
LBOOL NameUnicode; // Is Name in Unicode format?
char* FileName;
// File name as 7 bit ASCII string.
LBOOL IsURL;
// If true, FileName contains a URL.
char* UF;
// PDF 1.7. Same as FileName but Unicode is allowed.
LBOOL UFUnicode;
// Is UF in Unicode format?
char* Desc;
// Description.
LBOOL DescUnicode; // Is Desc in Unicode format?
UI32 FileSize;
// Decompressed stream size or zero if not known.
char* MIMEType;
// MIME media type name (RFC 2046).
char* CreateDate;
// Creation date as string.
char* ModDate;
// Modification date as string.
char* CheckSum;
// 16 byte MD5 digest if set.
