Tahuri WebP Tuhinga o mua ICO

Kei roto ko 16x16, 32x32, 48x48 me te 256x256 ā, kua taupokia e koe ia horopaki Windows me ngā kaiwhaiwāhi e tono ana. Ko tētahi ICO kotahi e pupuri ana i a rātou katoa, nā reira ka kōwhiria e te pūnaha whakahaere te ōrite tata rawa i te whakamātautau i tētahi rahi ki raro, ā, ka whakawātea. Ka tīmata mai i tētahi tapawhā WebP — ka whakawāteatia ētahi atu mea, ka whakawāteatia rānei.

Kāore. Ko ngā ahanoa whakawhāiti kua whakawhāititia ki roto i te WebP ko ngā raraunga pikitia noa iho ināianei, ā, ka tiaki i te ICO 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. Ka taea e te ICO te whakaae kia mahi tētahi pūranga ki tētahi taumahi, he rārangi pūranga, he whakatere papawhenua me tētahi tāpa whakataki me te kore e kitea tētahi o rātou. 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 ICO 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. Kāore te ICO i te āhua o te whakaahua whānui: he tapawhā, he iti, ā, kāore he kaiwhakawhanake whakaahua e whakaaro ana ki a ia hei pūranga mahi ā-ranga tuatahi.

Ka ora te mārama ina PNG, WebP, TIFF, GIF, SVG rānei te ICO. 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 ICO i te wāhi o ICO=JPG. Ko te ICO te āhua o te tohuāhua Windows, ā, ko te āhua o te whakaahua anake e whakaaetia ana e ngā kaiwhaiwāhi i te /favicon.ico.

Ka whakamātauria ngā tātai tae ICC whakatinana mai i te WebP, ā, ka hono anō ki te ICO 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 WebP → ICO 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 WebP 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 ICO i ngā ahu pikitia o te pūtake WebP. 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 ICO 60-80% iti iho i te WebP me te kore rerekētanga mārama i te tawhiti tirohia noa iho. Mō te kore ngaro ICO (PNG, TIFF), e tūmanako ana kia iti iho ngā pūtea — i te nuinga o te wā 5-30% mā te whakawhāititanga pai ake / LZW.
