This post covers applying “funky effects” to whole Arabic words – extending the work noted in my previous posts. It was was quite tricky to join a sequence of letters to form whole Arabic words as a single outline path,…
Over the last few evenings I’ve been exploring Bézier curves and effects that can be achieved through “flattening” glyph paths. I found a great C++ library called Clipper which lets you perform a number of interesting operations on polygons. After…
Just a short post to share an example of producing clock faces with Arabic numbers using LuaTeX’s nodes and glue. No drawing packages were used, all done with pdf_literal nodes and some basic trigonometry to calculate positions of the numbers,…
Just a short post to share another example from my on-going work on HarfBuzz A rather pointless example – without using any code to correctly place mark glyphs (e.g., vowels) – showing randomly coloured Arabic glyphs. Thanks to the power…
Building on the work of porting LuaTeX to build on Windows I decided to explore adding HarfBuzz to provide Arabic shaping. The excellent HarfBuzz API lends itself to some interesting solutions so here’s a quick post to show some early…
Follow-up example to the previous post A slightly more intricate example, this time showing the “before and after” effect of vowel adjustments. Again, this was achieved with a HarfBuzz-based pre-processor. TeX file generated using HarfBuzz Again, TeX code shown on…
