Yiziphi izindlela izithombe ezizokhishwa ngazo?

Izithombe zikhishwa ngendlela zazo yemvelo — ngokuvamile i-JPEG yezithombe, i-PNG yemifanekiso ene-transparency ne-TIFF yeziscanini zezikhala eziphezulu. Ungakhetha futhi ukuguqula konke ku-JPG noma ku-PNG.

Izithombe ezikhiwe ziyaphulukana nekhwalithi uma ziqhathaniswa nezangempela?

Cha. I-dokk.ai ifunda idatha yezithombe ngokungama emfuleni okuqukethwe we-PDF ngaphandle kokuklanya kabusha noma ukubuye kukode. Uma ugcina indlela yemvelo, ifayela elikhiwe liyafana iphikiseli nge-iphikiseli nalokho umbhali we-PDF akufakile.

Ngingakhipha izithombe ku-PDF ehlolwe?

Amafayela e-PDF ahlolwe afaka ukuscanwa kwakhasi lonke njengezithombe ezilodwa. Ukukhipha izithombe ku-PDF ehlolwe kukupha izithombe zescanini zamakhasi aphelele — enye ngekhasi. Uma i-PDF iqukethe izithombe eziningi ngekhasi (njenge-PDF enemakhasi amaningi ane-scans ngabanye), ngasinye sikhishwa ngakomba.

Kungani ngingakwazi nje ukukopisha nokuxhoma izithombe ku-PDF?

Ukukopisha nokuxhoma kusuka kumafundi e-PDF kubamba isithombe esinikwe yisikrini ngokunyundelwa kwesikrini (ngokuvamile i-72–96 DPI), hhayi isithombe sangempela esifakwe ngaphakathi. Lokhu kunikeza imiphumela engaziwa, enokunyundelwa okuphansi engafanele ukuprinta, izethulo noma ukusetshenziswa okunokusebenza.

Ziqanjwa kanjani izithombe ezikhiwe?

Izithombe ziqanjwa ngohlelo lwe-page-XX-image-YYY.ext — njengesibonelo page-03-image-002.jpg yesithombe sesibili ekhasini 3. Le ndlela yokuqamba ikuvumela ukubheka emuva isithombe ngasinye kuya ekhasini laso lesource.

Kwenzekani uma i-PDF iqukethe amakhulu ezithombe?

Zonke izithombe ezikhiwe zigxunyekwe ku-ZIP archive yokulayisha. Awukho umkhawulo wokusebenza wenombolo yezithombe ezikhiwe ngefayela. Isikhathi sokucubungula sikhula ngevolumo yedatha yezithombe isijobelele, hhayi inombolo yezithombe.

Ngingakhipha izithombe ezithile kuphela, hhayi zonke?

Yebo. Ngemuva kokulayisha, i-dokk.ai ikhombisa izifinyezo zazo zonke izithombe ezifakwe ngaphakathi. Ungakhetha izithombe ngasinye noma usebenzise izihlungi (ngokwekhasi, usayizi, indlela) ukuze ukhethe ingxenyana yokukhupha.

Onke amafayela e-PDF ane-izithombe ezifakwe ngaphakathi ezikhiphekayo?

Amafayela e-PDF angaba nezithombe ngezindlela ezimbili: njenge-objects yezithombe ezifakwe ngaphakathi (ezikhiphekayo ngokunyundelwa okugcwele) noma njengezikeyi zokunikeza ikhasi kusuka kwimifanekiso ye-vector (ezingakhipheki njengamaphikiseli). Uma i-PDF yenziwa kusuka kwimifanekiso ye-vector (njengomagrafu we-Excel noma izindwangu ze-Illustrator), lezizinto azikwazi ukukhishwa njengezithombe.

Yini usayizi omkhulu wefayela elingalayishwa?

Ama-akhawunti amahhala asekelwa amafayela e-PDF aze ku-50 MB. Ama-akhawunti e-Premium asekelwa aze ku-500 MB. Kwizinhlanganisela zedokhumenti ezikhulu ezine-izithombe eziningi zezikhala eziphezulu ezifakwe ngaphakathi, sebenzisa i-akhawunti ye-Premium noma isici sokuPhelisa ngamabala.

Ngingabuye ngihlele izithombe ezikhiwe ku-PDF entsha?

Yebo. Ngemuva kokukhipha nokuhlelwa noma ukukhethwa kwezithombe ofuna zona, sebenzisa ithuluzi le-dokk.ai Isithombe ku-PDF noma Iscanini ku-PDF ukuze uzihlanganyele edokumentini entsha. Lokhu kulungele ukwenza izinguqulo ze-PDF ezine-izithombe kuphela.

Izimo zokusetshenziswa

Ukukhipha izithombe zemikhiqizo kumakhalogi e-PDF abandisi
Ukubuyisela izithombe zangempela kusuka kumafayela e-PDF okulethwa kwezomthengi
Ukukhipha izindwangu kusuka ku-PDF yemibhalo yobuchwepheshe
Ukukhipha amagrafu kumbiko wonyaka wezethulo
Ukuqoqa izithombe zangempela ze-PDF ukuze zibuye zisetshenziselwe

Indlela yokusetshenziswa

1Layisha i-PDF yakho. I-dokk.ai ihlaziya isakhiwo somstifiketo futhi ibalule zonke izinsiza zezithombe ezifakwe ku-amakhasi onke.
2Buyekeza i-inventory yezithombe — inani, izindlela namasimu aqagulwe. Khetha zonke izithombe noma ezithile ukuze zikhishwe.
3Khetha indlela yokukhipha: gcina izindlela zemvelo noma uguqule konke ku-JPG (ngesetting yekhwalithi) noma ku-PNG. Ngezithombe zekhwalithi yokuprinta, sebenzisa i-PNG noma ugcine indlela yemvelo.
4Chofoza Khipha Izithombe. I-dokk.ai ikhipha isithombe ngasinye kusuka emfuleni okuqukethwe we-PDF ngochungechunge lwangempela.
5Layisha i-ZIP archive equkethe zonke izithombe ezikhiwe, ezinikwe igama ngokwekhasi nangokulandelana ukuze zitholakale kalula.

Uthole i-PDF equkethe izithombe zemikhiqizo, amagrafu, izindwangu noma izithombe ezihlolwe — manje udinga amafayela ezithombe akhona ngempela. Ukuvula i-PDF kumbheki bese uthatha izithombe zesikrini kulahleka ukunyundelwa futhi kunikeza amafayela angaziwa, angenamathelisi. Ukukopisha nokuxhoma kusuka kumfundi we-PDF kubamba isithombe esinikwe yisikrini ngokunyundelwa kwesikrini — cishe i-72–96 DPI, kude nokwangempela kwe-300 DPI. Ithuluzi lokukhipha izithombe le-dokk.ai likhipha isithombe ngasinye esifakwe ngaphakathi kusuka ku-PDF ngokuqondile kusuka esakhiweni sedatha sangaphakathi, ngaphandle kokunikeza ikhasi. Lokhu kusho ukuthi izithombe zikhishwa ngokunyundelwa nangendlela efanele lapho zafakwa ngayo ekuqaleni — ngaphandle kokukhipha umfuphi nokubuye kufakwe, ngaphandle kwezimpawu zokuklanya. Izindlela zokufaka ezisekelwe zihlanganisa i-JPEG, JPEG 2000, TIFF, PNG kanye nezithombe zemvelo. Isithombe ngasinye sikhishwa sibe nesakhiwo sayo sobala sokuqala. Ungakhetha ukugcina izindlela zemvelo noma ukuguqula konke ku-JPG noma ku-PNG ngesetting yekhwalithi enokuguqulwa. Isithombe ngasinye esikhiwe sanikwa igama ngenombolo yekhasi nangokulandelana — njengesibonelo page-03-image-002.jpg — okunikeza ukukwazi ukubheka emuva isithombe ngasinye kuya ekhasini laso lesource. Ithuluzi likhombisa inani, izindlela namasimu aqagulwe wazo zonke izithombe ezifakwe ngaphambi kokukhipha. Ungakhetha zonke noma izithombe ezithile kuludwe. Amafayela e-PDF amakhulu ane-amakhulu ezithombe ezifakwe ngaphakathi aphathwa ngokufanayo namancanyana — izinto zezithombe zifundwa ngokuqondile kusuka esakhiweni se-PDF ngaphandle kokunikeza amakhasi. Zonke izithombe ezikhiwe zigxunyekwe ku-ZIP archive yokulayisha. Amafayela e-PDF angempela alayishiwe nezithombe ezikhiwe ziyasuswa ngokuzenzakalela ngemva nehora elilodwa. Akukho okuqukethwe okugciniwe noma okusetshenziswa ngaziphi izinhloso ngaphandle kokukhipha okunceliwe.

Imibuzo ebuzwa njalo

Ukuphepha nobumfihlo

Amafayela e-PDF adluliselwa nge-TLS futhi aphathwa kumaserver acekelwe. Wonke amafayela — i-PDF yokufaka nezithombe ezikhiwe — iyasuswa ngokuzenzakalela ngemva nehora elilodwa. Akukho okuqukethwe okugciniwe noma okusetshenziswa ngaziphi izinhloso ngaphandle kokukhipha okunceliwe.
