`pdfEnumDocFonts`

Enumerate every registered font entry via a callback,

Category	Font enumeration
Note	coarse `TFontType` classification (see Remarks)

Purpose — Enumerate every registered font entry via a callback, receiving a PFNT handle usable with pdfReplaceFont/Ex.

Description — For each entry, calls EnumProc(Data, PDFFont, FontType, BaseFont, FontName, Embedded, IsFormFont, Flags). Passing EnumProc=NULL short-circuits to just returning the count (same value as pdfGetFontCount).

Declarations

int32_t __stdcall pdfEnumDocFonts(PPDF IPDF, void* Data, TEnumFontProc2 EnumProc);

Delphi

function pdfEnumDocFonts(const IPDF: PPDF; const Data: Pointer; EnumProc: TEnumFontProc2): Integer; stdcall; external 'LumasPdf.dll';

TEnumFontProc2:

Delphi

TEnumFontProc2 = function(const Data, PDFFont: Pointer; FontType: TFontType;
  const BaseFont, FontName: PAnsiChar; Embedded, IsFormFont: LongBool;
  Flags: Cardinal): Integer; stdcall;

Parameters

Parameter	Type	Description
`IPDF`	`PPDF`	Instance handle.
`Data`	`Pointer`	Opaque context passed through to each callback invocation.
`EnumProc`	`TEnumFontProc2`	Callback; `NULL` just returns the count without enumerating.

Return value — Total font entry count.

Remarks — coarse type classification. Every TrueType entry (whether a simple embedded face or a CID/Type0 setup) is reported as ftType0 with Embedded=TRUE; every other entry (standard-14, Type 1, CID-predefined) is reported as ftType1 with Embedded=FALSE. This is accurate for the common cases but does not distinguish, e.g., a simple embedded TrueType font from a genuinely CID-keyed Type0 font — both surface identically through this enumeration. IsFormFont is always FALSE and Flags always 0 in this build.
