JPG Ngā Pātai Auau mō te Tahuritanga
He aha te pūranga JPG?
+
Ko JPG he momo whakaahua raster e ngaro ana. Ka whakakore te kaituhi i ngā mōhiohio ā-whakaahua e iti ake ana te āhua o te tangata ki te whakawhiti i ngā rahi pūranga iti iho i ngā āhua ā-whakaahua ōrite. Ka whakawātea te whakawhāititanga o JPG i te ngaronga o te āhuatanga, nō reira ka whakakētia i ngā wā katoa mai i tētahi mātauranga kore ngaro i reira ka taea.
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 e whakaputa tonu ana ngā kāmera me ngā kāri whakataki i te JPG?
+
Nā te mea he ngāwari rawa te āhua o te tuhituhi i te wā tūturu i runga i ngā pūrere māmā, ā, nā te mea i hangaia tētahi whakatupuranga o ngā pūrere whakataki i runga i a ia, ā, kāore anō kia whakahōutia. Kāore te pūrere e whakamātau i tētahi whakataunga āhua, e tuhi ana i te mea e mōhiotia ana e tōna pūmanawa. Ko te take hoki he nui ēnei pūranga mō te mea e pupuri ana rātau, ā, ko te take o te tahuritanga o rātou ko te mea tuatahi e mahi ai tētahi tangata. 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.
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 tiakina te raraunga pūwhitiwhiti me te tauwāhi i te wā e tahuri ana au i tētahi JPG?
+
Ka mau i runga i te wāhi e tautoko ana te āhuahira ūnga i a ia — te tauira kāmera, te whakaata, te wā whakataki, me ngā taururuku GPS mēnā i whakatakitia e te pūrere. Ko te mea whakamutunga e hiahiatia ana kia whakaarotia i mua i te whakaputanga: ka taea e tētahi whakaahua i te wātea o te pūrongo te mau i te tauwāhi tika i tangohia ai. Ka whakawātea te metadata i te wā o te tahuritanga ina haere te whakaahua ki tētahi wāhi tūmatanui.
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 pēhea te tahuri i a au i te JPG ki tētahi atu hanga?
+
Ka tahuri te JPG ki PNG, WebP, TIFF rānei ina hiahiatia e koe tētahi whakaahua me te kore e ngaro atu te whakawhāiti - mō te pūranga, mō te whakarārangi, ina hiahiatia rānei e te mea tohu (whakaahua, whakatūnga tohu, whakaahua hua) te tino pono. Kāore he mārama a JPG, ka whakapeka anō i ia wā ka tiakina, ā, ka whakaputaina i te ātetetanga mārama i runga i te tae mārama me te kupu mārama.
Ka whakaiti te tahuritanga JPG i te āhuatanga whakaahua?
+
Ko te tahuritanga o JPG ki tētahi āhua kāore i te ngaro, pērā ki te PNG, ka kati i ngā pikitia o nāianei me te kore e ngaro anō. Ko te tahuritanga o JPG ki tētahi atu āhua kore e puta ai ki te ngaronga o te āhuatanga whakawhanake nā te mea ka whakakōrerotia anō e te kaituhituhi hou te raraunga kua ngaro - ka pupuri i te pūtake mēnā e whakarite ana kia whakakē anō.
E pupuri ana te MP4.to i a ahau i nga faila JPG?
+
Ka tuwheratia ōna pūranga JPG puta noa i te HTTPS, kāore anō kia pānui e te tangata, ā, ka tangohia mārō mai i a tātau pūnaha i muri i te tahuritanga. Kāore he tohu wai, kāore he whakaingoatanga mai, kāore he hokonga anō o ngā raraunga whakaahua.
