EnumDocumentFonts

Fonts

Description

Enumerates every /Font dictionary in the loaded document and fills one TPDFlibDocumentFont record per font with its /BaseFont name, type, encoding and embedding status, so a font inventory no longer needs repeated SelectFont calls with scalar getters

The function runs FindFonts first (idempotent, a second call only adds previously unseen dictionaries), then walks every discovered font, including fonts whose program is not embedded

Syntax

Delphi

Function TPDFlib.EnumDocumentFonts(Var Fonts: Array Of TPDFlibDocumentFont): Integer;

Parameters

Fonts	Caller-allocated array of `TPDFlibDocumentFont` records; only as many entries as the array holds are written

Return values

>= 0	The total font count of the document; when the caller's array holds fewer elements only the first `Length(Fonts)` entries are written and the return value may exceed the number of written entries, matching `EnumAttachments`
0	No document is loaded or the document contains no fonts

Remarks

Each record's FontID is the 1-based handle accepted by SelectFont, and the caller's currently selected font is preserved across the call

Encoding carries the textual /Encoding name such as WinAnsiEncoding or Identity-H; FontFileBytes is the encoded length of the embedded font program (/FontFile, /FontFile2 or /FontFile3) and is zero when the font is not embedded
