Sida Ay U Shaqeyso
Qalabkani wuxuu u beddelaa bogagga PDF sawirro gebi ahaanba biraawsarkaaga isagoo isticmaalaya PDF.js (pdfjs-dist) β injineerka sawirka PDF ee open-source ah ee Mozilla β la isku daray Canvas API-ga biraawsarka ee sumaynta sawirka. Faylkaaga waa si gudaha ah loo akhriyaa weligiisna server looma diro.
- 1PDF.js wuxuu falanqeeyaa faylkapdfjs-dist wuxuu si toos ah xasuusta ka akhriyaa qaab-dhismeedka binary-ga PDF-ka β fonts, sawirro vector ah, sawirro geli-geli ah, iyo tilmaamaha muuqaalka bogga β isagoo isticmaalaya renderer laftiisu JavaScript ku qoray. Web Worker gaar ah (oo laga shubay CDN) ayaa maareeya falanqaynta culus dhinaca kale ee thread-ka si boggu ugu sii jawaab-celiyo.
- 2Bog kastaa wuxuu ku sawiraa canvasBog kasta oo la codsaday, PDF.js wuxuu xisaabiyaa viewport oo lagu miisaamay DPI-gaaga la doortay. Booska iskudubaridka PDF ee default ahi waa 72 DPI, sidaa darteed sawir 300 DPI ah wuxuu isticmaalaa faktar miisaan ah 300/72 β 4.17x, wuxuuna soo saaraa canvas cabbir u dhigma. PDF.js wuxuu ku sawiraa nuxurka bogga oo dhan β qoraal, dariiqyo, sawirro β HTMLCanvasElement bannaan-shaashadeed ah isagoo isticmaalaya Canvas API 2D.
- 3Canvas wuxuu ku sumeeyaa qaabka aad dooratayKa dib sawirka, qalabku wuxuu wacaa canvas.toBlob() nooca MIME bartilmaameedka (image/png, image/jpeg, ama image/webp) iyo dejinta tayada. Tani waxay sumaynta u dhiibtaa codec-ka sawirka biraawsarka laftiisa β isla injineerka Chrome, Firefox, ama Safari si dabiici ah u isticmaalaan β waxayna soo saartaa Blob sawir la cadaadiyay oo xasuusta ku jira.
- 4Soo deji gaar ahaan ama ZIP ahaanBog la sawiray kastaa isla markiiba waxaa loo heli karaa sida object URL fiiriye iyo soo-dejin hal-fayl. Haddii aad soo dejiso dhammaan bogagga hal mar, laybreriga jszip ayaa ku ururiya Blobs-ka xasuusta ku jira ZIP archive client-dhinac ah, kadibna wuxuu bilaabaa hal soo dejin β wicitaan server ahi looma baahna marna.
PDF-kaaga waxaa si toos ah looga akhriyaa aaladdaada xasuusta biraawsarka isagoo isticmaalaya File API weligiisna lama soo shubo β sawirid, sumayn, iyo xidhmoyn dhammaantood waxay ka dhacaan gudaha tab-ka biraawsarkaaga.
