JPEG Tuhinga o mua JFIF Ngā Pātai Auau mō te Tahuritanga
He pēhea te tahuri i a JPEG ki JFIF me te kore e ngaro te āhuatanga whakaahua?
+
Whakataki i tōna JPEG me tātau kaiwhakarere e hoatu ana i te whakawhanaketanga o te āhua o te āhua mo te huaputa JFIF. Mō ngā ūnga kore ngaro (PNG, TIFF, BMP) ka tiakina ngā pīti i ia wā ki te iti; mō ngā ūnga ngaro (JPG, WebP) ka taea te whakarerekē i te take ā-waiho (whakamatau 90) i mua o te tāutunga. He ōrite te rerenga ira ki te.jpg: te whakawhāititanga whakangaromanga i runga i te DCT, i te nuinga o te wā me te 4:2:0 chromatic subsampling, i whakawhāititia ki roto i te JFIF, Exif rānei. Ko te raraunga whakaahua he JPEG noa iho; E tautuhi ana te JFIF anake i te kiato me ngā āpure tātuhi i te taha, nō reira ko te.jfif me te.jpg te pikitia ōrite.
Ka ora te tae CMYK o ahau i te tahuritanga ki JFIF?
+
Ka tahuri ki te sRGB, nā te mea kāore he tikanga CMYK a JFIF. Mō te whakamahinga mata, ko te mea tonu e hiahiatia ana e koe. Mō te tātuhi hokohoko, kāore — ka huri te nekehanga tauine i te āhua o te whakanaotanga o ngā tae mārō i runga i te tā, nā reira ka tukuna ki te tātuhi te taketake JPEG kaua ko te JFIF. Ko te whakaroanga.jfif e whakawātea ana i ngā Windows me ngā taupānga whatunga maha ki te whakakāhore i te pūkete, ko te take anake e whakarerekē ana tētahi tangata.
E pupuri ana te JFIF i te raraunga EXIF mai i tōku JPEG?
+
E whakawhirinaki ana, ā, i te wāhi e noho ai te ūnga ki te whakatakoto i a ia - te tauira kāmera, ngā whakaritenga whakakite, te tītara me ngā taururuku GPS katoa e whakawhiti ana. Ko GPS te āpure e whakaaro ana: mēnā ka whakaputaina te whakaahua, ka whakamahia te kōwhiringa metadata-strip kia kore ai e whakapāpāho i te wāhi i hoatu ai te whakaahua. He ōrite te paerewa o JPEG ki te JPG — ko te whakaroatanga-whā-whā te taketake, ā, ko te tohutoro-toru-whā anake nā te whakawhāititanga o te ingoa pūranga DOS 8.3.
Ka pupuri te tahuritanga o te tahuritanga JPEG ki JFIF?
+
Ka ora te mārama ina PNG, WebP, TIFF, GIF, SVG rānei te JFIF. Ka whakarerekē te tahuri ki JPG i te kanikani ā-autōhiko ki tētahi papamuri mā — mēnā e hiahiatia ana e koe te mārama, ka kōwhiria he ūnga mārama-mārama i te JFIF. Ko te JFIF te Rerekētanga Reke JPEG File - te whakaahuatanga o te tohuāhua e hanga ana i tētahi aho-kati JPEG mārō ki roto i tētahi pūranga whakarerekē.
Ka ora te āhua o tōku tātai tae (sRGB / Adobe RGB / CMYK) mai i te JPEG ki te JFIF?
+
Ka whakamātauria ngā tātai tae ICC whakatinana mai i te pūtake JPEG, ā, ka hono anō ki te huaputa JFIF i reira ka tautokona e te hanga (JPG, PNG, TIFF, WebP). Ko ngā hanga kāore i te tautoko i te tātai e hoki ana ki te sRGB me tētahi hipanga whakamātautau.
He aha e puta ana ki te metadata EXIF ina tahuri JPEG ki JFIF?
+
E pupuritia ana te EXIF o te kāmera (ISO, shutter, lens, GPS) mā te pūmau i te wā o JPEG -> JFIF ina tautokona e ngā āhua rua ngā metadata. Ka whakamahia te whakarerekē ā-whakaaro hei whakawātea i ngā metadata i mua i te whakataki mēnā e hiahia ana kia tiritiri i ngā whakaahua me te kore tauwāhi, pūrere-kitenga rānei.
Ka taea e au te tahuri-whakahaere i ngā rau o ngā pūranga JPEG ki JFIF i tētahi wā?
+
He — ka tangohia he maha ngā pūranga JPEG ki te rohe tāpiritanga, ā, ka whakatū i te raupapa. Ka whakaaetia e te taumata wātea 100 MB ia pūranga; Kāore he kōpaka-whakahaere, ā, ka haere tonu ngā kaimahi whakawhāiti ake, nō reira ko te 200-pihi te whakamutu i raro i ngā minu e rua.
He pēhea te ōrite o JPEG ki JFIF ki Photoshop / GIMP mō te mahi ōrite?
+
Mō te tahuri ā-whakahaere, ka whakarewaina e tātau te pūtautau pūrākau pū
He aha te rongoā me ngā ahu o te JFIF?
+
Ko te whanonga pūmau ko te 1:1 — he ōrite ngā ahu o ngā pikitia o tōtou huaputa JFIF ki te pūtake JPEG. Mēnā e hiahiatia ana e koe te whakarea hei wāhanga o te tahuritanga, ka whakamahia /resize-image/ i muri, ka whakapāpāho rānei i ngā mahi me te utauta /image-pipeline/.
He iti rawa te JFIF i te faila me te kore ngā ahanoa e kitea ana?
+
Mō JPG / WebP, ko te āhuatanga 75-85 e hua ana i tētahi JFIF 60-80% iti iho i te JPEG me te kore rerekētanga mārama i te tawhiti tirohia noa iho. Mō te JFIF kore ngaro (PNG, TIFF), e tūmanako ana ki ngā pūtea iti iho — i te nuinga o te wā 5-30% mā te whakawhāititanga pai ake / LZW i te pūtake. He ōrite te JFIF ki te JPG, nō reira ko te whakahōu ingoa, te tahuri rānei he mahi metadata, kaua ko te whakakōrero anō.
He tūmataiti ahau JPEG i te wā o te tahuritanga?
+
He — e whakaata ana ngā pūranga JPEG i whakarewaina i roto i ngā kaimahi motuhake, ā, ka tangohia i roto i ngā minu. Kāore anō tātau kia pānui, ki te penapena, ki te tiritiri rānei i te raraunga pūwhiti. Kua tuhituhitia te matapihi tūturu i te /privacy/.
He mahi te JPEG ki te JFIF whakarerekē mō ngā whakaahua nui rawa (50MP+)?
+
He mea tika mō te wāteatanga tae atu ki te 100 MB. Ka whakahaeretia e te utu ngā tāuru nui ake (300 MB+) me ngā hōhonutanga pūtauira-pōtuhi (16-bit PNG, 32-bit float TIFF, HEIF 10-bit). Ka rere te pūtauira i ngā rārangi pūtauira kia tauinetia ai te pūmahara me te tatau rārangi, ehara i te tatau pūtauira katoa.
