[PDFBOX-4545] PdfRenderer fails to render subsetted font

• Type: Bug
• Status: Open
• Priority: Minor
• Resolution: Unresolved
• Affects Version/s: 2.0.15
• Component/s: PDModel, Rendering
• Flags: Patch
• Assignee: Unassigned

Description

In 2.0.3, TrueTypeEmbedder initializes FONT_FILE2 with the full font (1) and then writes the subset later on save (2) (3).

In 2.0.15 TrueTypeEmbedder now only initializes FONT_FILE2 if !embeddedSubset (4).

This results in PDFRenderer failing to find and use the intended font when using a PDDocument that has never been saved.

Attached patch restores the original behavior to work around the issue.
