He aha te JPG?
+
He hōputu whakaahua a JPG (JPEG) e whakamahi ana i te kōpeketanga ngaronga, he mea tino pai mō ngā whakaahua me ngā whakaahua uaua.
He rite tonu te JPG ki te JPEG?
+
Ko te mea kotahi tonu: kotahi paerewa, kotahi te rerenga ira, e rua ngā whakamāoritanga. E tīari ana te whakaroatanga-toru nā te mea e toru anake ngā pūāhua i whakaaetia e ngā ingoa pūranga DOS o mua, ā, ko te kupu-whā te taketake. Ka whakahōu te ingoa o tētahi pūranga mai i tētahi ki tētahi atu, kāore e huri, kāore e whakaiti, ā, ka pānui e ia kamera, ka whakataki, ka tātari. Ko te mea anake e rerekē ana ko te pūmanawa e tika ana ki te whakatau i tētahi pūranga e tana whakaroatanga. Ko JPG te paerewa JPEG mai i te tau kotahi mano e 1992, ā, i muri i ngā tekau tau e toru ko te āhua tonu o te nuinga o ngā kāmera me te nuinga o ngā whatunga e whakamahia ana mō ngā whakaahua.
He mea kino ake te tiaki i tētahi JPG i ia wā?
+
He, ā, ko te mea kotahi e mōhiotia ana mō te āhua. Ka whakarewa anō e ia tiakitanga te whakawaenga ngaro i runga i tētahi whakaahua kua puta mai, kia āhua ai ngā ahanoa - e kitea ana hei ārai i te tuhituhi me ngā arorangi i runga i ngā taitapa mārō i muri i te tokomaha o ngā whakatupuranga. Ka whakakē i tētahi matua kore ngaro, ka whakawātea ki JPG kotahi, i te mutunga, kaua e whakawātea i te whakatupuranga o te whakatupuranga, me te tiaki anō i te pūtahi. He ngaro te JPG: ka hurihia te whakaahua ki tētahi DCT, he nui, he waehere entropi, me te kāwae āhuatanga e whakahaere ana i te nui e whakawāteatia ana.
He aha te take i tuku ai e ia kāmera me te tātari ki a au he JPG?
+
Nā te mea ko te āhua o te mekameka katoa o te whakaahua i whakatū i ngā tekau tau i mua, ā, kāore he mea e tika ana te mōrearea o te pūnaha ki te kaimahi tātari. Ka tuwhera te raraunga pūoko, ā, ka whakawaeheretia i roto i te kāmera anō, i tētahi tautuhinga āhuatanga i whakawāteatia i roto i tētahi rārangi, ā, ko te mea e tū ana i runga i te kāreti he whakaahua kua oti. Ko te take kāore te tahuri tuatahi o tētahi whakaahua i te wātea o te ngaronga e māharahara ana te tangata — kua puta kētia te wātea o te ngaronga, i roto i te kāmera.

I raro i te 75 ka tīmata te whakaaturanga o ngā ahanoa ki te āhua o te kiri, te rangi me ētahi wāhi matatini nui; i runga ake i te 95 ka tere te tupu o te faila i te mea kāore pea e kitea e tētahi te rerekētanga. Kāore te whakaritenga i te āhuatanga o te whakaahua, he whakataunga mō tēnei whakawāteatanga motuhake — nō reira ka kōwhiria mō te wāhi e haere ai te faila, me te pupuri i te taketake mō te wā e whai ake nei e hiahiatia ana e koe tētahi urupare rerekē.
Ka taea e JPG te pupuri i te tae CMYK mō te tātuhi?
+
Ka taea, nā reira ko ngā pūranga mai i ngā rerenga mahi tātuhi i ētahi wā e āhua āhua kē ana i runga i te mātakina: ko ngā tae e tautuhia ana i roto i ngā ōrautanga pepa mō te tātuhi, kaua i te mārama mō te mātakina. Ko te nuinga o ngā āhuahira tīwae ko te RGB anake, nō reira me whakamāoritia tētahi tahuritanga, ā, ko te whakamāoritanga e tata ana ki te - te tino whakangāwaritanga o te cyan me te kararehe. Mō ētahi mea e haere ana ki tētahi tātuhi, ka pupuri i te taketake i te taha o te mea e tahuri ana.
He mea hira rānei he toru tekau tau te JPG?
+
Ko te pakeketanga anake ehara i te raruraru — he maha ngā āhuahira mai i taua wā e pai tonu ana, i te mea kua tekau tau te whakatinana i a rātou. Ko te mea e hiahiatia ana ko te wā: he pūranga iti, he pūkaha iti, kāore he whatunga, me ngā āhuatanga kāore e hiahiatia ana e tētahi. Ki te āhua tonu o ēnei whakaaro, he pai te āhuahira. Ki te kore rātau, ko te take ki te tahuri.
Ka taea e au te whakamahi i te JPG hāngai ki tētahi pouwāhi whatunga?
+
He — ko ia kaitiaki o nāianei e whakawātea ana i te āhua taketake, nō reira kāore e hiahiatia he tārua whakarerekē, ā, kāore he tahuritanga i te wā o te whakaputanga. Ko te pātai e toe ana he taumaha ake i te tautoko: ko te whakaahua ōrite i roto i tētahi āhua tīpae o nāianei he toru o te rahi i te āhuatanga āhua ōrite, e tika ana kia mahi i tētahi mea e puta ana i runga ake i te whiri. E whakawhāiti ana te JPG i ngā whakaahua māori, ā, ka taea te whakamātau i ia pūrere, te kaiwhaiwāhi me te tātari i te tīariari.
Ka taea e au te whakahōu te whakaroa i te wāhi i te whakarerekētanga o JPG?

Ka whakaputaina e te whakahōutanga he faila ko te ingoa e whakapuakina ana he mea kāore i te tuku i ōna ihirangi, ā, ko te mea e whakatuwheratia ai, ka whakakāhore rānei i te faila, ka pāpāho rānei. Ko te whakawāteatanga whāiti kotahi ko ngā hanga e rua e tino ōrite ana i raro i ngā ingoa rerekē — ā, ahakoa he haumaru ake te whakaroanga tika i te whakahōutanga.
Ka taea e au te mahi i tētahi JPG nui ake me te kore e whakawātea?

He pai te rua mō tētahi hipanga ki runga o te toru, ā, kāore e huri i tētahi tātuhi ki tētahi tātuhi. Ka tīmata mai i te tārua nui rawa o koe, ā, ka whakarerekē i te rahi ki raro i te wāhi e tīari ana te kōwhiringa.
