The latest version of the yExport extension package is 1.5.

Technical Requirements

• Graph visualization library yFiles for Java 2.12 to 2.18 version series.
• Oracle J2SDK 1.6 or higher for software development with yExport.
• Oracle J2RE 1.6 or higher to execute yExport powered programs.
• A browser to view the HTML documentation.

yExport 1.5 - Changes Since 1.4.0.1

Improvements

• Reduced file size of PDF documents created by PDFOutputHandler.
• Upgraded from FreeHEP VectorGraphics 2.1.1 to FreeHEP VectorGraphics 2.4. See the FreeHEP VectorGraphics GitHub page for more information.

Bugfixes

• Fixed rendering hints management of copied Graphics2D instances in the FreeHEP VectorGraphics library code.
• Fixed problems with drawing complex shapes to EMF output in the underlying FreeHEP VectorGraphics library code.
• Fixed font encoding issues for non-unicode fonts like Symbol or Zapf Dingbats in the FreeHEP VectorGraphics library code that resulted in ArrayIndexOutOfBoundsException.

Changes in Technical Requirements

• Building and running yExport based applications now requires at least Java 1.6 (due to upgrading to FreeHEP VectorGraphics 2.4).

Changes in Licensing

• Adopted Apache Software License for the FreeHEP VectorGraphics package. Prior to yExport 1.5, the included FreeHEP VectorGraphics package was licensed under LGPL.

yExport 1.4.0.1 - Changes Since 1.4

Bugfixes

• Fixed Mac OS X JDK 1.7 compatibility issues in the FreeHEP VectorGraphics library code that resulted in NoClassDefFoundError or UnsatisfiedLinkError when exporting PDF documents with embedded raster images.
• Corrected the Size entry in the trailer dictionary of PDF documents in the underlying FreeHEP VectorGraphics library code.

yExport 1.4 - Changes Since 1.3

Improvements

• PDFOutputHandler: Added support for cyclic color gradients of type GradientPaint.
• PDFOutputHandler: Added support for (semi-) transparent color gradients of type GradientPaint.
• OutputHandler: Added factory method createGraphicsContext.

Bugfixes

• Improved embedding fonts into PDF output in the underlying FreeHEP VectorGraphics library code.

yExport 1.3 - Changes Since 1.2

Minor Features Added

• PDFOutputHandler: Added pageOutlinesEnabled property that can be used to turn off automatic bookmark creation for generated pages.
• PDFOutputHandler: Added constant VIEW_FORMAT that may be used to create PDF documents for which the page size is determined by the size of the exported graph's view.

Improvements

• EPSOutputHandler: The page size for the created EPS documents is now determined by the size of the exported graph's view.

Bugfixes

• Fixed JDK 1.7 and OpenJDK 1.6 compatibility issues in the FreeHEP VectorGraphics library code that resulted in java.lang.ExceptionInInitializerError.
• EMFOutputHandler: Fixed aspect ratio in EMF output.

yExport 1.2 - Changes Since 1.1.0.2

Minor Feature Added

• OutputModule: Added support for ignoring selection state when exporting to one of yExport's supported file formats.

Bugfixes

• Fixed clipping to retain correct color/paint and transform properties in PDF output.
• Fixed problems with drawing complex paints to EMF output in the underlying FreeHEP VectorGraphics library code.
• Improved embedding fonts into EPS output in the underlying FreeHEP VectorGraphics library code.

yExport 1.1.0.2 - Changes Since 1.1.0.1

Licensing

yExport license terms have been updated to match the current yFiles for Java graph visualization library license terms.

Bugfixes

• Fixed writing affine transforms in the underlying FreeHEP VectorGraphics library code.

Improvements

• OutputModule: method mainrun has been enhanced to use the original view's background renderer for export if that renderer is of type DefaultBackgroundRenderer.

yExport 1.1.0.1 - Changes Since 1.1

Bugfixes

• Fixed value of Class-Path attribute in META-INF/MANIFEST.MF of yexport.jar.

Improvements

• Improved handling of image data in VisualTransferable's getTransferData method.

yExport 1.1 - Changes Since 1.0

Minor Features Added

• EPSOutputHandler: replaced boolean property fontEmbeddingEnabled with enum property textRenderingPolicy to support regular text, text with embedded fonts, and vectorized text.
• PDFOutputHandler: replaced boolean property fontEmbeddingEnabled with enum property textRenderingPolicy to support regular text, text with embedded fonts, and vectorized text.
• SWFOutputHandler: added getter/setter for SWF version. Currently, SWF file format versions 7 and 8 are supported.
  Note: The main difference between versions 7 and 8 is the security policy applied to embedded links. Version 8 of the SWF file format allows embedded links to either local or external/network resources, but not both.
• SWFOutputHandler: added support for hyperlinks.
  Note: Currently, only local links are supported for SWF version 8 files, i.e. embedded external (or network) links are blocked by Flash player implementations.

Incompatible API Changes

• OutputHandler: removed obsolete constants
  • KEY_TEXT_RENDERING,
  • VALUE_TEXT_RENDER_DEFAULT,
  • VALUE_TEXT_RENDER_DEFAULT,
  • VALUE_TEXT_RENDER_QUALITY, and
  • VALUE_TEXT_RENDER_SPEED
• EPSOutputHandler: replaced boolean property fontEmbeddingEnabled with byte property textRenderingPolicy.
• PDFOutputHandler: replaced boolean property fontEmbeddingEnabled with byte property textRenderingPolicy.
