Type0FontFactory
in package
Factory that builds a complete Type 0 composite font stack from TrueType font data.
Produces the object graph: Type0Font (top-level) /Encoding /Identity-H /ToUnicode -> CMap stream (GID -> Unicode) /DescendantFonts [CIDFontType2] /CIDSystemInfo (Adobe-Identity-0) /FontDescriptor -> FontDescriptor /FontFile2 -> embedded font stream /DW (default width) /W (per-CID widths array) /CIDToGIDMap /Identity

Methods
fromTrueTypeData()
Build the complete Type 0 font stack from parsed TrueType data.
public
static fromTrueTypeData(TrueTypeData $data, array<string|int, int> $usedCodepoints[, bool $vertical = false ]) : PdfStream, 6: array}
The subsetter renumbers kept glyphs into a compact 0..N-1 range, so
the returned unicodeToGidSubset map points at the post-subset
GIDs that callers should emit in content streams. The /W widths and
/ToUnicode CMap are likewise built against post-subset GIDs so the
three views agree.
Parameters
- $data : TrueTypeData
-
Parsed font data
- $usedCodepoints : array<string|int, int>
-
Unicode codepoints used in the document
- $vertical : bool = false
-
Use Identity-V encoding for vertical writing mode
