Air 11 Màrt, chaidh a’ chiad fhoillseachadh mòr de 1.0.0 den leabharlann grafaigean vector XNUMXD a chumail PlutoVG, sgrìobhte ann an C agus air a chuairteachadh fo chead MIT. Chan eil eisimeileachd treas-phàrtaidh aig an leabharlann.
Feartan leabharlainn:
- stoidhlichean tarraing loidhne;
- sgàileadh cruaidh, caisead agus inneach;
- clòidean agus teacsa;
- gearradh agus sgrìobhadh;
- cruth-atharraichean;
- Dealbhan.
Tha an leabharlann air a chleachdadh ann am pròiseactan eile leis an ùghdar: LunaSVG и PlutoSVG.
Atharraichean:
- Cleachd SemVer airson àireamhachadh dreach.
- Macros air a chur ris PLUTOVG_EMPTY_POINT agus PLUTOVG_EMPTY_RECT.
