PDF kuya PNG Imibuzo Evame Ukubuzwa Yokuguqulwa

Yini i-DPI i PNG 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 PNG amafayela. I-PNG isebenzisa ukucindezelwa kwe-DEFLATE phezu kwemigqa yokuskena ehlolwe, ngakho wonke ama-pixel ahlala ngokugcwele, kanye ne-8-bit alfa channel ephelele.

Ingabe i-PNG 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 PNG ngemuva ngaphandle kokushintsha ifomethi futhi. I-PNG iyisinqumo esifanele sezithombe-skrini, amalogo, umdwebi we-line kanye nanoma yini eneziphetho eziqinile noma ezicacile — akukho ukusakaza, akukho umbala obandayo.

Ingabe amafayela PNG azokhula kangako?

Okuningi kunalokho okubonayo, ngoba PNG 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.

Ingabe ngithola isithombe esisodwa ngamakhasi?

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

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

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-PNG izogcina u-PDF ukusesha okusembhalweni?

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

Yini ubukhulu behele lwekhasi elijwayelekile PNG?

Ikhasi le-150-DPI PNG 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.

PNG

Amafayela e-PNG asekela ukucaca futhi asebenzisa ukucindezela okungenakulahlekelwa, okwenza afaneleke kakhulu kuma-graphics, ama-logo, kanye nezithombe-skrini.
