Tahuri PSD Tuhinga o mua GIF

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 GIF hei pupuri i a rātau. Whakataki te PSD hei matua mahi me te GIF 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. Ko te tauine 256-waera o GIF e whakangaro ana i ngā taumata me ngā whakaahua ā-whitiāhua, ā, he nui ake te rahi o ōna rahi faila mō te whakatangi i te WebP, MP4 rānei.

Ka tahuri ki te sRGB, nā te mea kāore he tikanga CMYK a GIF. 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 GIF.

Kāore he raraunga pikitia, kāore. Ko ngā āhuahira e rua e rokiroki ana i te whakaahua me te kore whakawhāiti, kia ōrite ai te whakaahua e puta mai ana ki te mea i whakaurua, ā, ka taea te tāruatanga i te wā kore. Ko te huringa ko te rahi o te faila, ā, ko ngā āhuatanga haere - te hōhonu o te tae, ngā tātuhi whakawhāiti, ngā apa me te whakateretanga e tautokona ana i waenganui i ngā āhuahira kore ngaro.

Ka ora te mārama ina PNG, WebP, TIFF, GIF, SVG rānei te GIF. Ka whakarerekē te tahuri ki JPG i te kanikani ā-autōhiko ki tētahi papamuri mā. Mēnā e hiahiatia ana e koe te mārama i roto i te hua, ka ūngatia he mārama-mārama GIF i te wāhi o GIF=JPG. Ko te GIF te āhua o te CompuServe 1987, ā, ko te take anake i ora ai ko te mea e whakaata ana.

Ka whakamātauria ngā tātai tae ICC whakatinana mai i te PSD, ā, ka hono anō ki te GIF i reira te āhua o te tātai 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 pupuri ana i ngā tae i runga i te nuinga o ngā whakaaturanga o nāianei.

Ko te EXIF o te kāmera (ISO, shutter, lente, GPS coordinates) e tiakina mā te pūmau i te wā o PSD → GIF ina tautokona e ngā āhuahira e rua ngā metadata. Ka whakamahia te kōwhiringa whaiaro hei whakakore i ngā metadata i mua i te whakataki mēnā e hiahiatia ana kia tiritiri ngā whakaahua me te kore tauwāhi.

He — ka tangohia e tātau he maha ngā pūranga PSD ki te rohe tāurunga, ā, ka whakatūtautau i a rātou i te taha kotahi. Ka whiwhi ngā kaiwhakamaori wātea ki te 100 MB ia pūranga; Kāore he kōpaka i ia pūranga, ā, ka haere tonu ngā kaimahi ōrite, nō reira ka oti te 200-pihi i raro i te rua minu.

Mō te tahuri ā-tūturu o te āhua, ka whakahaeretia e tātau te pūtautau ōrite libpng / libjpeg-turbo / libwebp / ImageMagick e whakamahia ana e te kaiwhakawhanake papatono, me te āhuatanga pūtea ōrite. Ko te rerekētanga ko te whakahaere rōpū whakarara — ka whakatuwheratia e ngā taupānga papatono tētahi rārangi i tētahi wā; ka whakaaetia e tātau tētahi rōpū.

Ko te pūmau ko te 1:1 — e pupuri ana tōtou GIF i ngā ahu pikitia o te pūtake PSD. Mēnā e hiahiatia ana e koe te whakarea hei wāhanga o te tahuritanga, ka whakamahia /resize-image/ i muri i te tahuritanga, ka whakapā atu rānei ki te utauta /image-resize/.

Mō JPG / WebP, ko te āhuatanga 75-85 e whiwhi ana i te GIF 60-80% iti iho i te PSD me te kore rerekētanga mārama i te tawhiti tirohia noa iho. Mō te kore ngaro GIF (PNG, TIFF), e tūmanako ana kia iti iho ngā pūtea — i te nuinga o te wā 5-30% mā te whakawhāititanga pai ake / LZW. Ka whakatangitangi te whakatangitanga GIF i ngā wāhi katoa - ngā kaiwhakahaere maimoe, ngā pāpāho, ngā taupānga kōrero, me ngā kaiwhaiwāhi katoa e whakawātea ana i a ia me te kore whakatūnga pūrere.

He — e whakaata ana ngā pūranga PSD i whakarewaina i roto i ngā kaimahi motuhake, ā, ka tangohia i roto i ngā minu. Kāore anō tātau ki te whakaako, ki te penapena roa, ki te tiritiri rānei i te raraunga pūtau. Ko te matapihi tūturu e tuhituhi ana i /privacy/.
