New Features in Version 4.0.x

  • MiniGUI also provides new APIs to lay out, shape, and render glyphs from complex and mixed scripts, such as Arabic, Thai, and Indic.

  • We tuned and optimized MiniGUI's logical and device font interfaces to support the new features above.

  • We introduced a Slice Memory Allocator for fast concurrent memory chunk allocation.

  • Cleanup and tune code for GCC 7.3.
