Problem Corrections:

  • Corrects an issue in which embedding fonts could drop character glyphs from text.
  • Corrects an issue with subsetting previously embedded CIDType2 fonts, in which the CIDToGIDMap entry, when present in the font, was not used in setting the glyphs to be used in the subset.
  • Corrects an issue where font merging was prematurely ended if many similar subset names were found.
  • Corrects an issue in which fonts could be embedded with a substitute font when a font reference is not found as a system resource.  Also corrected an issue in which re-embedding fonts could lead to fonts that were no longer working. Improved logic to abandon font subsetting when the result would end up with a font that has no glyphs.

Version 1.3.1 (July 13, 2018)

Enhancements:

  • Adds new option to down-convert images from 16 bits per component (bpc) to 8 bpc.

Version 1.1 (March 22, 2018)

Enhancements:

  • PDF Optimizer Includes latest version of the PDF Checker tool.
  • For Windows, the PDF Optimizer installer includes an option to subsequently run the PDF Checker installer.
  • For Linux, the distribution includes a PDF Checker self extracting installation file, which prompts the user to accept a license agreement. Then, the process allows for the installation of PDF Checker in a default directory under the current or designated directory.
  • Adds support of a new JSON Color Conversion category. User may select a color profile to apply, define a conversion intent, and replace existing calibrated profiles in the PDF document with a different profile.
  • Adds support of a new JSON category to allow a user to save a PDF export file so that it is compliant with the PDF/A-1b (PDF Archive) format.
  • The transparency quality settings have been adjusted to more appropriate values for high, medium, and low-quality output.
  • Improves merging of font subsets when the PDSaveOptimizeFonts flag is used.
  • PDF Optimizer now by default first looks for the profile in the installation directory. If the product cannot find that profile file there, it looks at the command line statement, and treats the profile included there as the path to the profile file.
  • Application and installer are now signed with the certificate from Datalogics.
  • Adds specific error for when the user is unable to save output results to the output file specified.
  • Changes default installation directory to “Program Files/Datalogics/ PDFOptimizer.”
  • Adds a new process that looks for situations that would require incremental saves for an export PDF document, such as a signed PDF document or a need to include usage rights. The process ends with an error message, rather than continuing to process the optimization.
  • Adds optimization for 16-bit per channel (bpc) J2K images (a compression format for JPEG image files) and applies subsampling to JPEG compression.
  • Adds new option “write-output-even-if-increase-in-size” that can be used to decide whether to keep outputs when they cannot be reduced in size.
  • Renames the option “optimize-only-if-reduction-in-size” to “optimize-images-only-if-reduction-in-size” for clarity.

  • Removes a potential problem starting up the program on certain Windows machines in which “api-ms-win-core-libraryloader-l1-1-1.dll” is reported as missing.
  • Corrects a problem with optimization in which text could become damaged when subsetting Type1 fonts with a custom encoding.
