Tahuri SVG Tuhinga o mua PNG

Ko te kōwhiringa o te rahi nui rawa e whakaaturia ana e koe, nā te mea ko tēnei te hipanga i te mutunga o te faila i te whakamāramatanga-whāiti. Ka rokirokitia tētahi SVG hei huarahi pāngarau, ā, ka whakarārangitia i tētahi rahinga; ko te PNG he kāwai pikitia tauwhāiti, ā, ka taea anake te whakawhānui i muri mai. Ka whakawātea i te rua o te rahi whakaaturanga e hiahiatia ana mēnā ka whakawhāiti ki tētahi mātauranga DPI tiketike. Ka tino pai te whakataki i te SVG i tētahi rahinga, ka noho te whakamātautau, ka rapua, ka rerekē i te kupu pūnoa, ā, ko te nuinga o te wā he hautanga o te rahi o te PNG ōrite. I hangaia a PNG i te tau kotahi mano e 1996 hei whakakapi kore whakawhiwhinga ki te GIF, ā, ka noho hei hanga whakaahua pātata kore ngaro o te Wīwī.

I roto i te SVG, ko te kupu he kupu tūturu — ka taea te tīpako, te kimi, te whakahōu anō, ā, e hiahiatia ana te pūāhua tuhituhi kia wātea, kia whakawātea rānei hei whakawātea i te mea e hiahiatia ana. Ka huri te tahuri mai i te SVG i taua kupu ki ngā pikitia, ki te kupu tuhinga rānei, i runga anō i te ūnga; Ka huri ki te SVG ka puta mai anake te kupu tūturu mēnā he mata tuhipānui te pūtake.

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 PNG. 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 PNG i te wāhi o PNG=JPG.

Embedded ICC color profiles are read from SVG and re-attached to the PNG 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 SVG → PNG 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 SVG 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 PNG i ngā ahu pikitia o te pūtake SVG. 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 PNG 60-80% iti iho i te SVG me te kore rerekētanga mārama i te tawhiti tirohia noa iho. Mō te kore ngaro PNG (PNG, TIFF), e tūmanako ana ki ngā pūtea iti iho — i te nuinga o te wā 5-30% mā te whakawhāititanga pai ake / LZW. Ko PNG te kōwhiringa tika mō ngā whakaahua mata, ngā tohu, ngā toi raina me ētahi atu mea me ngā taitapa mārō, mārama rānei — kāore he whakawhāiti, kāore he tae.

He — ka whakarewaina ngā pūranga SVG 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/.
