Tahuri WebP Tuhinga o mua TIFF

Kāore. Ko ngā ahanoa whakawhāiti kua whakawhāititia ki roto i te WebP ko ngā raraunga pikitia noa iho ināianei, ā, ka tiaki i te TIFF i rātou kia kore ai i te tango i a rātou. Ko te nuinga o te wā ka nui ake te faila, i ētahi wā he maha ngā wā nui ake. Ka tika tonu te mahi i mua i te whakarerekētanga, nā te mea kāore e whakawātea anō ngā whakarerekētanga i te whakatupuranga tuarua o te ngaronga i runga ake. E whakahaeretia ana e TIFF a CMYK, te hōhonutanga 16-biti, ngā tātai ICC whakawātea me ngā tuhinga pāpāho maha, ko te mea tika e hiahiatia ana e te tātuhi me ngā rerenga mahi pūranga. 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.

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. Ko te WebP te āhua whakaahua o Google 2010, i hangaia mai i te kaituhituhi VP8, ā, i whakaritea kia whakakapia i te JPG, PNG me te GIF i te kotahi.

Ko te tāruatanga tuatahi anake e ora ana, nā te mea he āhua tūturu te TIFF kāore he wāhi hei rokiroki i te toenga. Mēnā he mea hira te whakatangitanga, ka ūngatia tētahi hanga e whakatangi ana, ka tahuri rānei ki tētahi kāwai ataata, ā, ka pupuri i te nekeneke. Ko te āhua o TIFF ko tōna tūkinotanga — e rua ngā TIFF ka taea te hanga i ngā āhuatanga rerekē kia kore ai te pūmanawa e āhei ki te ako i tētahi i runga i te atu — ā, he nui ngā pūranga.

Ka ora te mārama ina PNG, WebP, TIFF, GIF, SVG rānei te TIFF. Ka whakarerekē te tahuri ki JPG i te kanikani ā-autōhiko ki tētahi papamuri mā. Mēnā e hiahiatia ana e koe te mārama i te hua, ka ūngatia he mārama-mārama TIFF i te wāhi o TIFF=JPG. Ko TIFF te Rerekētanga Reketere Pikitia i te tau kotahi mano e 1986, ā, ko te āhua o te karapa, te whakaputanga, me ngā umanga tātari i whakawaengatia.

Embedded ICC color profiles are read from WebP and re-attached to the TIFF output where the format supports it (JPG, PNG, TIFF, WebP). Formats without profile support fall back to sRGB, which keeps colors consistent across most modern displays.

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

He — ka tangohia e tātau ētahi WebP ngā pūranga ki te rohe tāpiri, 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 ā-tahi, nā reira ka oti te 200-pitanga i raro i te rua minu.

Mō te tahuritanga ā-tūturu o te āhua, ka whakarewaina e tātau te pūtautau ōrite libpng / libjpeg-turbo / libwebp / ImageMagick e whakamahia ana e te kaiwhakawhanake papamuri, me te ōritetanga o te huaputa. Ko te rerekētanga ko te whakahaere rōpū whakatata - ka whakatuwheratia e ngā taupānga papamuri tētahi pūranga i tētahi wā; ka whakaaetia e tātau tētahi rōpū.

Ko te pūmau ko te 1:1 — e pupuri ana tōtou TIFF i ngā ahu pikitia o te pūtake WebP. Mēnā e hiahiatia ana e koe kia whakarea hei wāhanga o te tahuritanga, ka whakamahia /resize-image/ i muri i te tahuritanga, ka whakapāpā rānei ki te /image-resize/.

Mō JPG / WebP, ko te āhuatanga 75-85 e whiwhi ana i te TIFF 60-80% iti iho i te WebP me te kore rerekētanga mārama i te tawhiti tirohia noa iho. Mō te kore ngaro TIFF (PNG, TIFF), e tūmanako ana ki ngā pūtea iti iho — i te nuinga o te wā 5-30% mā te whakawhāititanga pai ake / LZW.

He — ka whakarewaina ngā pūranga WebP i te mahi takitahi, ā, ka tangohia i roto i ngā minu. Kāore anō tātau ki te whakaako, ki te rokiroki roa, ki te tiritiri rānei i te raraunga pikitia. Ko te matapihi tiaki katoa e tuhituhi ana i /privacy/.
