Fil-11 ta’ Marzu, saret l-ewwel rilaxx maġġuri ta’ 1.0.0 tal-librerija tal-grafika vettorjali XNUMXD PlutoVG, miktuba f'C u mqassma taħt il-liċenzja MIT. Il-librerija m'għandha l-ebda dipendenzi minn partijiet terzi.
Karatteristiċi tal-librerija:
- stili ta' tpinġija ta' linji;
- sfumatura solida, gradjent u minsuġa;
- fonts u test;
- żbir u kompożizzjoni;
- trasformazzjonijiet;
- Stampi.
Il-librerija tintuża fi proġetti oħra tal-awtur: LunaSVG и PlutoSVG.
Bidliet:
- Użu SemVer għan-numerazzjoni tal-verżjoni.
- Miżjuda macros PLUTOVG_EMPTY_POINT u PLUTOVG_EMPTY_RECT.
