Changes for version 3.023 - 2021-07-15

  • lib/PDF/Builder.pm, INFO/DEPRECATED FUTURE: Builder.pm's "default()" method may need to be renamed. Some time after Perl 5.26, Perl::Critic started flagging "default" as a reserved keyword. This needs to be further investigated.
  • .github/workflows/test.yml Update PATH for new ImageMagick level.
  • lib/PDF/Builder/Resource/XObject/Image/TIFF_GT.pm, t/tiff.t Fix for ticket #154 by @carygravel, and add a test for bilevel+alpha where rows are not filling out a full array of bytes.
  • version (for distribution build), README.md, lib/PDF/Builder.pm, t/00-all-usable.t, .gitignore Modified to prereq Perl 5.22 instead of 5.20 (is 6 years old now). Also Graphics::TIFF minimum upped to 16 and Image::PNG::Libpng to 0.57 due to changes. Keep files up to date on GitHub so can successfully run without full build. Put "version" in GitHub as it's now fairly involved and I don't want to accidentally lose it!
  • Makefile.PL, MANIFEST, META.json (add), META.yml (add), .perl-version (deleted), optional_update.pl (add), README.md Modify build process to have optional prereqs properly installed. Also ensure that mandatory and optional prereqs are consistently updated and handled. Since the vast majority of users will use the default of installing all optional prereqs, the selection process has been moved from Makefile.PL to optional_update.pl (for those manually running Makefile.PL). optional_update.pl updates Makefile.PL, META.json, and META.yml upon selection of which (if any) optional prerequisites are to be installed on a manual run of Makefile.PL. I don't want to risk getting META.json and META.yml (needed for properly installing the "recommends" optionals) out of sync by failing to update them at install from Makefile.PL, so all are now shipped with all optionals selected.
  • .gitattributes, .github/workflows/test.yml Added .gitattributes to stop certain line-end changes that were causing CI tests to fail, add Windows tests to CI. From @carygravel.
  • lib/PDF/Builder/Content.pm Problem with use of "pi" constant caused a warning on compile in one CPAN smoke test (Perl 5.20 for one tester). Changed "-pi" in one expression to "-1*pi" and hopefully that will silence the messages.
  • lib/PDF/Builder.pm, lib/PDF/Builder/Page.pm, INFO/DEPRECATED, t/annotate-deprecations.t Per PDF::API2, simplify Builder's ' fixed' to ' opened'. Rename 'openpage()' to 'open_page()' and deprecate old name.
  • INFO/Changes-ver_2, t/pdf.t Per changes in PDF::API2, sync up with 2.040 release. There are still a small number of changes not implemented (yet) in PDF::Builder, which either appear to be unnecessary, or the underlying code has changed too much to cleanly port the changes without a massive rewrite.
  • t/deprecations.t Update for new PDF::API2 t-tests and a number of other deprecated items. Test both deprecated interfaces and their replacements.
  • lib/PDF/Builder/Content/Text.pm, examples/BarCode-Boxes-Content- ContentText-Rotated.pl, examples/021_synfonts-022_truefonts- 022_truefonts_diacrits_utf8-023_cjkfonts-024_bdffonts-040_annotation Per 3.022 change of lead() to leading(), update examples to use leading() instead of lead().
  • In releases 3.020 through 3.022, INFO/DEPRECATED erroneously listed PDFStr() and PDFUtf() as being scheduled for removal after October 2022. These two routines ARE deprecated (use PDFString() instead), but there are currently no plans to REMOVE them.
  • .gitignore, lib/PDF/Builder.pm, lib/PDF/Builder/Basic/PDF/File.pm, t/tiff.t Some minor cleanup, fix TIFF tests because grouped skips don't seem to work properly on Strawberry Perl, initialize $xmin in File.pm to prevent error message.
  • lib/PDF/Builder/Basic/PDF/Filter/LZWDecode.pm, lib/PDF/Builder.pm, lib/PDF/Builder/Resource/XObject/Image/TIFF-TIFF_GT.pm, lib/PDF/Builder/Resource/XObject/Image/TIFF/File-File_GT.pm, t/filter-lzwdecode.t, t/tiff.t, t/00-all-usable.t, Makefile.PL Further improvements to TIFF LZW file handling [ref GH 151 and PR 156] for single and multi-strip, and horizontal predictor. Continuation of work to stop converting LZW-compressed TIFF to Flate. Code by @carygravel. Increase required Graphics::TIFF version to 10 due to fix in GT.
  • examples/README, examples/examples.output Discuss the issue of close, heavy lines in the example bar codes appearing to merge or "blot" together. This is at least partially a consequence of lower resolution display screens (rounding errors), and although the bars separate when printed, I'm still concerned that they will not be reliably scannable.
  • All files (.pm and .pl) containing $LAST_UPDATE can now access this string from outside the file, in the same manner as $VERSION. The variable declarator has been changed from 'my' to 'our' during package build.
  • INFO/Changes-ver_2, /lib/PDF/Builder/Basic/PDF/String.pm, t/string.t Per PDF::API2 changes related to [RT 134957], change some regex flags to fix encoding of \n in a PDF string.
  • t/tiff.t add version check (not just if installed) for ImageMagick and Ghostscript. Some smoke tests apparently blew up for using too low level versions. If too low version, or any problems determining the version, tiff.t fails gracefully by skipping those tests. From @carygravel.
  • t/tiff.t use a temporary directory for various test files, enabling use from a Read-Only directory and/or running tests in parallel (from @ppisar, #153).
