This release is the first one to drop PDFWriterTesting from the archived package. This reduces the download size from around ~100mb to 3mb, which is not bad for a day of work.
Thanks for a very good proposal @darcy-shen :).

v4.6

In this release:

• XMake support. The project now includes the required lua file to make it an official xmake package. Thanks @darcy-shen for his contribution.
• Bundled Tiff library upgrade. Bundled tiff lib is upgraded to 4.6 (matching hummus version is unintentional haha). This might break your code if you have been using the bundled tiff code directly, which good chances you didn't and so nothing to worry about. I hope the upgrade process is not going to be too difficult. In the project it was just a matter of few type updates. The upgrade happened as part of the discussion in #226 to avoid a future deprecation of the basic types used in libtiff. Hope its not gonna inconvenience you.

What's Changed

• Add xmake build definition and enable ci by @darcy-shen in #228
• feat: upgrade bundled libtiff to 4.6 by @galkahana in #227

v4.5.12

Emoji's support

What's Changed

• feat: implementation of Colrv1 fonts by @galkahana in #225

Full Changelog: v4.5.11...v4.5.12

v4.5.11

What's Changed

• Color emoji support for true type COLR version 0. that is, the simpler implementation by @galkahana in #224

WriteText method has now a limited but not inexistent ability to handle true type color emojis via support of COLR table version 0. This is the simple version supporting solid colors, but not gradients. I'll probably need to add COLR table version 1 and maybe even support SVG fonts for a full support. TBD on when/if that's gonna happen.

As a side effect I added support for setting opacity in either of the following manners:

• as a parameter to WriteText method inOptions parameter (inOptions.opacity).
• as a parameter to Draw* methods inOptions paraemter (inOptions.opacity)
• directly set via SetOpacity method

Value should be double 0..1 with 0 being completely transparent, and 1 is fully opaque. a special value of 255.0 means not-set on options structures.

The implementation follows @chunyenHuang work in hummusRecipe, creating an ExternalGState object for every opacity value provided, and reusing them when given the same value, as well as setting the opacity for both fill and stroke drawing at the same time, for the sake of convenience.
