Yintoni i-DPI? Ithetha ntoni iPPI? Yintoni isisombululo?

C

Ngokuhamba kwexesha, ubuninzi abantu (ngokubanzi abantu abancinci) abachitha ixesha phambi kwekhompyuter bukhula, nto leyo ibangela iimpendulo ezininzi, kuba siyakwazi ukubona abantu banokuba ziingcali zekhompyuter ngenxa yenani elikhulu leyure abahamba ngokwenza nawuphi na umsebenzi kuyo.

Ngalo lonke eli xesha, kunokwenzeka ukubonisa indlela abantu abalufumana ngayo ulwazi olufanelekileyo malunga iinkalo ezininzi zolwazi ngaphakathi kwesayensi yekhompyuter kunye noyilo, Ukuzivumela ukuba bajongane neengxaki kunye neemfuno ezivela kwindawo yabo enxulumene nale mimandla.

Yintoni i-DPI kunye ne-PPI?

Ngale ndlela, eli nqaku liza kubonelela ngolwazi kwezinye amagama abhaliweyo (DPI, PPI), kunye nokusonjululwa kwekota, Izinto ezibalulekileyo ukuzazi kwihlabathi loyilo lwegraphic, ngendlela enokuthi umfundi athathele ingqalelo intsingiselo yala magama nokubaluleka kokwazi umahluko phakathi kwamagama ezinto DPI kunye nePPI, ezinokudideka rhoqo.

Ngale ngqiqo, siqhubeka nokunikezela ngokuqwalaselwe apha.

DPI

Xa senza ushicilelo, umfanekiso wethu unokufumaneka kwi izigqibo ezininzi Kwaye njengoko sisazi kakuhle, isisombululo sichaphazela kakhulu umgangatho wemveliso yethu yemizobo. Ngale ndlela, i-DPI iyahambelana namanqanaba okusombulula ukuba abashicileli bangabonisa ngexesha lokushicilela.

Ngale ndlela, sinokuqikelela ukuba ngenxa yezoqoqosho, ziya kubakho Iindidi phakathi kwamanqanaba eDPI eprinta nganye. Nangona kunjalo, kubonakala ngathi kukho amanqanaba abamele i-IPR kwaye kubonakala ngathi 300 DPI banokwanela ukuvelisa umfanekiso osemgangathweni.

Nangona kunjalo, kukho abashicileli banamhlanje abanokuba namanqanaba e-DPI ukuya kuthi ga kwi-3000.

Ngaphandle kwamanqanaba aphezulu e-DPI ingaqinisekisa imifanekiso esemgangathweniKuyimfuneko ukuba ubuqili kunye nokuthobela amanqanaba ezinokuthi ziveliswe zizixhobo ngokwesiqhelo, ngale ndlela, oko kuthetha ukuba abasebenzisi kufuneka balumke ngazo zonke iinguqulelo abazenzayo kwi-DPI yabashicileli babo xa bekukhangelo imifanekiso esemgangathweni ophezulu.

La manyathelo ayasebenza nakwisikena, ngenxa yesi sizathu, kucetyiswa ukuba xa kusenziwa imisebenzi yokuskena, basebenze nabo Amanqanaba e-DPI engekho ngaphantsi kwama-300, ngendlela yokuba imifanekiso ibonise amanqanaba asemgangathweni afanelekileyo.

I-PPI / PPP

Njengokuba kukho izigqibo zemifanekiso yokuprinta kunye nokuskena, kukho izigqibo malunga nokubek'esweni.

Ukuba sibhekisa kwisisombululo somhloli wethu, kufuneka kuthathelwe ingqalelo ukuba, Ababeki esweni baya kuzisa ezabo izigqibo kwaye ngale ndlela, Ii-IPRs kufuneka zilungiselelwe i-PPI / PPP Kwaye la magama okuchonga iya kuba ngalawo manqanaba okusombulula esiya kuwafumana ekubekweni esweni kwethu, apho imifanekiso (nokuba yeyiphi na i-DPI) iya kulungiswa ngexesha lokuboniswa kumfanekiso wokubeka esweni.

Kukho amathandabuzo malunga Umahluko phakathi kwePPI kunye nePPP kwaye, umahluko kuphela phakathi kwala magama mabini awunantsingiselo, kuba eyokuqala sisishunqulelo esiNgesini kunye nesesibini, isifinyezo kwisiSpanish.

Isigqibo

Le yokugqibela ayinanto ingaphantsi okanye iphantsi kune Inani lee-pixels ze-mega ezinomfanekiso. Ngale ndlela, umfanekiso onesisombululo se-1024 × 768 pixels mega, kuya kubakho ukubala inani elithile leepekseli kumfanekiso ngamnye.

Ngokubanzi, inani eliboniswe ngentla lelona liqhelekileyo kwimifanekiso emininzi eboniswa kumaqonga ahlukeneyo.

Ngale ndlela, sinokuyazi loo nto la magama mathathu abhekisa kwizinto ezahlukeneyo. Inokuba luncedo kakhulu ukuphatha olu lwazi xa ukuyila imalunga, kananjalo nokushicilela nokuskena okuchaphazelekayo, ukuze sazi ukuba umgangatho weeprojekthi ezimelweyo zingangumgangatho ophakamileyo.
