Release Notes

zendframework/zend-barcode

v2.8.0

Compare Source

Added

• #​48 adds the methods setProvidedChecksum(bool $value) (and the option providedChecksum) and getProvidedChecksum(). These allow indicating that the barcode text includes a checksum value for purposes of validation.

Changed

• Nothing.

Deprecated

• #​49 deprecates Zend\Barcode\Renderer\Pdf. The renderer uses the now-abandoned zendframework/zendpdf package, and, as such, is deprecated as well, and scheduled for removal with version 3.0.0. We will release a separate PDF renderer package at a later date that consumes a 3rd party PDF library.

Removed

• Nothing.

Fixed

• Nothing.

• #​45 fixes
  rotation calculations.

• #​46 fixes
  generating checksum for EAN5 and Identcode/Leitcode. These barcodes

Compare Source

Added

• Nothing.

Changed

• Nothing.

Deprecated

• Nothing.

Removed

Fixed

• #​24 updates the SVG
  renderer to remove extraneous whitespace in rgb() declarations, as the
  specification dis-allows whitespace, and many PDF readers/manipulators will
  not correctly consume SVG definitions that include them.

• #​36 provides several
  minor changes to namespace imports for the Zend\Barcode\Object namespace to
  ensure the package works on PHP 7.2.
