From 4165cd23ba06a370c46c8f2d58b6a8672516a758 Mon Sep 17 00:00:00 2001 From: Michael R Sweet Date: Thu, 6 Mar 2025 16:04:00 -0500 Subject: [PATCH] Fix some issues discovered by some PDF checking tools: - Extremely small floating point numbers would be written with exponential notation my the pdfioContent functions. They are now written with up to 6 decimal places of precision with excess trailing 0's removed. - 8-bit (simple) TrueType fonts were embedded without a Widths array, which made Acrobat Reader sad but nobody else... - Switched to using the WinANSI base encoding, which is CP1252. --- CHANGES.md | 3 + pdfio-content.c | 368 ++++++++++-------------------------------------- 2 files changed, 74 insertions(+), 297 deletions(-) diff --git a/CHANGES.md b/CHANGES.md index ed25d1a..ff7750d 100644 --- a/CHANGES.md +++ b/CHANGES.md @@ -15,6 +15,9 @@ v1.5.0 - 2025-03-06 - Updated documentation (Issue #95) - Updated the pdf2txt example to support font encodings. - Fixed potential heap/integer overflow issues in the TrueType cmap code. +- Fixed an output issue for extremely small `double` values with the + `pdfioContent` APIs. +- Fixed a missing Widths array issue for embedded TrueType fonts. v1.4.1 - 2025-01-24 diff --git a/pdfio-content.c b/pdfio-content.c index 5557a51..b22f319 100644 --- a/pdfio-content.c +++ b/pdfio-content.c @@ -355,7 +355,7 @@ pdfioArrayCreateColorFromPrimaries( double matrix[3][3];
