Derisa s\u00eb fundmi, n\u00ebse kishte nevoj\u00eb p\u00ebr pun\u00eb me fontet TrueType, kishte vet\u00ebm dy opsione: FreeType dhe stb_truetype. E para \u00ebsht\u00eb nj\u00eb mjet shum\u00eb i madh, e dyta mb\u00ebshtet nj\u00eb num\u00ebr mjaft t\u00eb vog\u00ebl funksionesh.<\/p>\n

ttf-parser ndodhet diku n\u00eb mes. Ai mb\u00ebshtet t\u00eb gjitha ato tabela TrueType (formati TrueType p\u00ebrb\u00ebhet nga shum\u00eb tabela t\u00eb ve\u00e7anta binare) q\u00eb mb\u00ebshtet edhe FreeType, por nuk merret me vizatimin e vet\u00eb glif\u00ebve.<\/p>\n

Megjithat\u00eb, ttf-parser p\u00ebrmban shum\u00eb dallime t\u00eb tjera t\u00eb r\u00ebnd\u00ebsishme:<\/p>\n

    \n
  1. ttf-parser \u00ebsht\u00eb shkruar n\u00eb Rust pa p\u00ebrdorimin e unsafe. FreeType dhe stb_truetype jan\u00eb shkruar n\u00eb C.<\/li>\n
  2. ttf-parser \u00ebsht\u00eb realizimi i vet\u00ebm i sigurt (memory-safe). Leximi i memories s\u00eb rast\u00ebsishme nuk \u00ebsht\u00eb i mundur. N\u00eb FreeType vazhdimisht rregullojn\u00eb dob\u00ebsit\u00eb, nd\u00ebrsa stb_truetype n\u00eb parim nuk \u00ebsht\u00eb i destinuar p\u00ebr t\u00eb lexuar fontet e rast\u00ebsishme.<\/li>\n
  3. ttf-parser \u00ebsht\u00eb implementimi i vet\u00ebm thread-safe. T\u00eb gjitha metodat e analiz\u00ebs jan\u00eb konstante. P\u00ebrjashtimi i vet\u00ebm \u00ebsht\u00eb caktimi i koordinatave p\u00ebr fontet variab\u00ebl, por kjo funksionalitet \u00ebsht\u00eb reentrant.

  4. ttf-parser \u00ebsht\u00eb implementimi i vet\u00ebm q\u00eb nuk p\u00ebrdor alokimin n\u00eb «grumbull». Kjo lejon p\u00ebrshpejtimin e analiz\u00ebs dhe parandalon problemet gjat\u00eb OOM.<\/li>\n
  5. Gjithashtu, pothuajse t\u00eb gjitha operacionet aritmetike dhe konvertimet e tipeve numerik\u00eb kontrollohen (inkluzivisht statikisht).<\/li>\n
  6. N\u00eb rastin m\u00eb t\u00eb keq, biblioteka mund t\u00eb hedh\u00eb nj\u00eb p\u00ebrjashtim. N\u00eb k\u00ebt\u00eb rast, n\u00eb API-n\u00eb C p\u00ebrjashtimet do t\u00eb kapen dhe funksioni do t\u00eb kthej\u00eb nj\u00eb gabim, por nuk do t\u00eb bjer\u00eb.<\/li>\n<\/ol>\n

    Dhe pavar\u00ebsisht t\u00eb gjitha garancive t\u00eb siguris\u00eb, ttf-parser gjithashtu \u00ebsht\u00eb realizimi m\u00eb i shpejt\u00eb.
