PDF kuya TIFF Imibuzo Evame Ukubuzwa Yokuguqulwa

Yini i-DPI i TIFF ibonisa ngayo?

Imenyu yesinqumo kwikhasi lokushintsha linikeza i-72 DPI yokusetshenziswa kwesikrini, i-150 DPI, eyisi default, ne-300 DPI yoshicilelo. Ukucaciswa okuphezulu kunikeza okucacile kodwa okukhulu TIFF amafayela. I-TIFF iyindawo yokuqoqa engaphezu kwe-codec: ingagcina idatha engacindezelwanga, i-LZW, i-ZIP noma i-JPEG, kuze kube yi-32 bits ngasinye, ngekhasi eliningi kwifayela elilodwa.

Ingabe i-TIFF ixhasa ukubukhali?

Ifomethi ikhona, kodwa umsuka awuna-alpha ukuwunika - amafreyimu wevidiyo namakhasi ashicilelwe agcwele ukucasuka, ngakho wonke ama-pixel afika aqinile. Isixhumanisi se-alpha sisebenza ngemuva: kusho ukuthi ungasakaza isiqephu se TIFF ngemuva ngaphandle kokushintsha ifomethi futhi. I-TIFF iphatha i-CMYK, 16-bit ububanzi, i-ICC efakwe ngaphakathi namaprofayili namadokhumende amakhasi amaningi, okuwukuthi okuthile okudingayo ukuphrinta nokugcinwa kwemisebenzi.

Ingabe amafayela TIFF azokhula kangako?

Okuningi kunalokho okubonayo, ngoba TIFF igcina wonke ama-pixel ngokugcwele kungafani nokulinganisela. I-1080p ihlala ifinyelela ku-2-5 MB futhi i-4K ihlala ifinyelela ku-6-15 MB, ngakho-ke ukukhishwa okude kusebenza ngokushesha. Lokhu kuyibhizinisi elilungile uma izithombe zidla ukukhiqizwa okuqhubekayo, futhi okubi uma zihamba ngqo kwikhasi le-web.

Ingabe ngingenza isiqephu kuphela se-PDF endaweni yazo zonke?

Kuyo kuphela ikhasi lokuqala. Imenyu yamakhasi inikeza Zonke ikhasi noma ikhasi lokuqala kuphela, okunembile ngesihloko noma ngethumbnail. Kunoma iyiphi ikhasi elisha, hlukanisa i PDF kuqala nge /pdf-split/ futhi uguqule kuphela amakhasi ofuna.

Ingabe i-PDF yengxenye yokuguqulwa ingase ihlolwe?

Kuxhomekeka ngokuphelele ukuthi umbhalo ongokoqobo ukhona noma cha. I-PDF eyenziwe kusuka kudokhumende ifaka umbhalo ongokoqobo futhi itholakale; i-PDF eyenziwe kusuka ku-scans noma izithombe yisithombe sombhalo futhi ayinjalo, kuze kube i-OCR ifaka umbhalo. /pdf-ocr/ yenza lokho, futhi kufanelekile ukuqhuba ngaphambi kokuguqulwa okulindeleke ukufundwa kwegama.

Ingabe ngithola isithombe esisodwa ngamakhasi?

Yebo. Ikhasi ngalinye libonisa njengehele leTIFF, elilinganiselwe ngohlelo lwekhasi, ngakho ikhasi elilodwa ledokhumende linikeza i-TIFF eyodwa kanti elinobude linikeza isithombe esisodwa ngakhasi.

Ingabe ngiguqula kuphela ezinye izixhumanisi ze-PDF zibe yi-TIFF?

Imenyu yamakhasi inezinto ezimbili ezikhethwayo: wonke amakhasi, okuyiphutha, noma ikhasi lokuqala kuphela. Akukho indlela yokuchwetheza kuluhlu lwekhasi. Ezinye amakhasi, hlukanisa i PDF kumakhasi ahlukile nge /pdf-split/ futhi uguqule amakhasi ofuna.

Ingabe i-TIFF izogcina u-PDF ukusesha okusembhalweni?

Akukho — u-PDF ku-TIFF uguqula umbhalo ube yi-pixels. Uma ufuna ukuphuma okudinga ukuphenywa, gcina umsuka njenge-PDF bese usebenzisa ithuluzi lokukhishwa kombhalo. Ukuphuma kwesithombe (TIFF) kukhombisa okubonakalayo, OCR ukungenisa, noma ukuqhubekekisa sithombe.

Yini ubukhulu behele lwekhasi elijwayelekile TIFF?

Ikhasi le-150-DPI TIFF lekhasi le-A4 lingu-200-800 KB (PNG) noma 50-150 KB (JPG quality 85). Ukuphindaphinda ngekhasi lokubala ubukhulu be-bundle — ikhasi le-100 PDF le-PNG bundle livame ukuba ngu-30-80 MB.

PDF

Amafayela e-PDF agcina ukufometha kuwo wonke amadivayisi nezinhlelo zokusebenza, okwenza kube kuhle ukwabelana ngamadokhumenti okudingeka abukeke afana yonke indawo.

TIFF

Amafayela e-TIFF asekela ukujula kwe-bit ephezulu kanye nokucindezelwa okungenakulahlekelwa, okulungele ukuthwebula izithombe zobungcweti kanye nokuphrinta.
