Tahuri PSD Tuhinga o mua WebP

Ka whakatatatia rātau, i te wā katoa, ki roto i tētahi whakaahua whāiti. Ko ngā tikanga whakakotahi, ngā mīhini, ngā apa whakahōu me te kupu whakahōu katoa e whakamātautia ana ki ngā pītaki whakamutunga nā te mea kāore he hanganga a WebP hei pupuri i a rātau. Whakataki te PSD hei matua mahi me te WebP hei whakanaotanga. Ka pupuri te PSD i ia whakataunga whakahuatuhi e taea te whakarerekē, nā reira ko te āhua matua mō te mahi hoahoa e whakahōutia ana. Kei te WebP tonu te waeine tuarua i waho o te kaiwhaiwāhi — kāore e whakaaetia e ngā rerenga mahi tātai, ngā hanganga Tari tahito me ētahi whare tātari.

I te āhuatanga 80-85 kāore e kitea te rerekētanga i te tawhiti tirohia noa iho, ā, ko te nuinga o te wā ka whakapeka te faila e 60-80%. Ko te ātete he huarahi kotahi: ko te tiaki i te WebP anō i te wā kotahi e whakakotahi ana i ngā ahanoa. Whakataki te PSD hei matua, ā, ka whakahōu anō te WebP mai i tēnei i te wā e hiahiatia ana e koe he rahi hōu. Ka whakarato rā anō te WebP i ngā āhuatanga ngaro me te kore ngaro, me te mārama ā-arawhiti me te whakaata i te taha kotahi.

Ka tahuri ki te sRGB, nā te mea kāore he tikanga CMYK a WebP. 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 PSD kaua ko te WebP.

Ka ora te mārama ina haere ki PNG, WebP, TIFF, GIF, SVG rānei. Ka whakarerekē te tahuri ki JPG i te kanikani ā-autōhiko ki tētahi papamuri mā - mēnā e hiahiatia ana e koe te mārama, ka ūngatia tētahi hanga mārama-mārama i te wāhi o WebP.

Ka whakaakona ngā tātai tae ICC whakawaitara mai i te pūtake PSD, ā, ka hono anō ki te huaputa WebP i reira te āhua e tautoko ana i a ia (JPG, PNG, TIFF, WebP). Ko ngā āhua kāore i te tautoko i te tātai e hoki ana ki te sRGB.

E pupuritia ana te EXIF o te kāmera (ISO, shutter, lens, GPS) mā te pūmau i te wā o te tahuritanga PSD → WebP ina tautokona e ngā āhua rua te metadata. Ka whakamahia te kōwhiringa whaiaro hei whakakore i te metadata i mua i te whakataki mēnā e hiahia ana kia tirohia ngā whakaahua me te kore tauwāhi.

He — ka tangohia e tātau he maha ngā pūranga PSD ki roto i te rohe whakaata, ā, ka whakatūtautautia rātau i te taha kotahi. Ka whiwhi ngā kaiwhakamaori wātea ki te 100MB ia pūranga; Kāore he kōpaka i ia pūranga, ā, ka haere tonu ngā kaimahi ā-tahi, nā reira ka oti te 200-pitanga i raro i te rua minu.

Mō te tahuritanga āhuahira māmā, ka whakarewaina e tātau te pūtautau ōrite libpng / libjpeg-turbo / libwebp / ImageMagick e whakamahia ana e te kaiwhakawhanake papamuri, me te āhuatanga ōrite. Ko te rerekētanga ko ngā utauta papamuri e whakatuwheratia ana i tētahi pūkete i tētahi wā; ka whakaaetia e tātau tētahi rōpū, ā, ka whakarewaina i te āhua kotahi.

Ko te whanonga tōmua ko te 1:1 — he ōrite ngā ahu o ngā pūwhitinga o tōtou WebP ki te pūtake PSD. Ka whakamahia tētahi hipanga /resize-image/ motuhake i muri i te tahuritanga mēnā e hiahiatia ana e koe te whakaiti, te whakawhānui rānei hei wāhanga o te rerenga mahi.

Mō JPG / WebP, ko te āhuatanga 75-85 e whiwhi ana i te pūkete 60-80% iti iho i te pūtake PSD me te kore rerekētanga mārama i te tawhiti tirohia. Mō ngā whāinga kore ngaro (PNG, TIFF), e tūmanako ana kia iti iho te tiakitanga - i te nuinga o te wā 5-30% mā te whakawhāiti pai ake / LZW.

He — e whakarewaina ana ngā pūranga PSD i whakarewaina i roto i ngā kaimahi takitahi, ā, ka tangohia i roto i ngā minu. Kāore anō tātau ki te whakaako, ki te rokiroki, ki te tiritiri rānei i te raraunga pikitia. Ko te kaupapahere whaiaro katoa me te matapihi tautuhi i te /privacy/.
