HexaPDF 0.35.0 - Fallback Fonts Published on Sunday, 07 January 2024

This release contains many small features and fixes and breaking changes. So make sure you read the changelog before upgrading!

The most notable additions and changes are:

• The document layout engine gained support for fallback fonts. Just define the fallback fonts using the new configuration option ‘font.fallback’ and you are set.

  

  The fallback font support is also used when generating appearances for AcroForm text fields.

• It is now possible to use the document layout functionality for a single canvas/page via the new HexaPDF::Content::CanvasComposer class, easily instantiated via canvas.composer.

• The style properties ‘align’ and ‘valign’ have been renamed (breaking change) to ‘text_align’ and ‘text_valign’ so that the old names can be used for box placement. With the addition of the style property ‘mask_mode’ one has now even more control over box placement, e.g. overlaying boxes is now possible (see the added example).

• The new ‘psd’ command for hexapdf inspect provides easier to read output for page content streams, e.g. by decoding the text output parts and showing the nesting levels.

As always, have a look at the changelog for an overview of all changes.
