Kusintha PNG Mafunso Ofala
Kodi mtundu wa m'mawu oyambirira umakhudza pamene mukusintha?
+
Amachita. PNG ndi lossless DEFLATE ndi 8-bit alpha channel ndi 16-bit kuwala, kotero kuti si nthawi zonse amawononga pa re-kupulumutsa koma amapeza lalikulu pa zithunzi za zinthu. Izi ndi zomwe zimasankhidwa ngati mirror ikhoza kuchitidwa polembanso fayilo kapena kufunikira kuchotsa koyamba.
Pali china chilichonse chokhudzana ndi PNG chomwe chiyenera kuzindikira?
+
Yes — palibe slider yabwino yosayenera - PNG imayenda m'mphepete mwa maulendo a bit-exactly, choncho chinthu chokhacho chomwe chimasintha mtengo wanu ndi kukula kwa fayilo. Kuyenera kukhala nthawi yoyenera kuti muchepetse chinthu chomwe simungathe kubwezeretsa.
Kodi Kusintha PNG imawoneka bwanji fayilo?
+
Concretely, maudindo kapena masamba amasinthidwa m'malo mwake ndi kulemba m'mbali mwake, kotero zotsatira ndi zoona za m'mphepete mwake wa mkati ndi chilichonse china chosinthidwa. You choose the axis — horizontal produces a mirror image, vertical produces an upside-down reflection — and the whole file is transformed on it.
Kodi pali kusiyana kotani pakati pa kuzungulira ndi kuzungulira?
+
Kusinthasintha kumasintha zinthu m'mphepete mwa axis ndipo kumapanga chithunzi cha m'mphepete; kuzungulira kumasinthasintha popanda kusintha chilichonse. Malemba ndi chitsanzo chabwino: amawerenga m'mbuyo pambuyo posinthasintha ndipo amasunga kumvetsera pambuyo posinthasintha.
Kodi alpha channel kupulumuka?
+
Ndiko. PNG ndi TIFF zimagwiritsa ntchito ma channels a 8-bit alpha ndipo zimasungana mpaka pamapeto. Zimakonzedwa ngati mwafuna kugwiritsa ntchito mtundu womwe sumakhala ndi ma channels a alfa, pamenepo ma pixels owoneka bwino amaphatikizidwa pa mthunzi wobiriwira.
Kodi ndingapeze chiyani pa Kusintha PNG?
+
PNG, BMP ndi TIFF ndi mafomu a raster osatha omwe amagwira ntchito moyenera, ndipo mabungwe othamanga (JPG, WebP, GIF) amagwira ntchitonso ngati mukufuna kuwagwiritsa ntchito pamodzi. TIFFs osiyanasiyana amapezeka ndikuyang'aniridwa patsamba ndi tsamba.
Kodi pali malire a kukula kwa fayilo pa Kusintha PNG?
+
Yesani: maakaunti aulere amapanga zithunzi mpaka 5 MB; mabungwe osatha kuwononga amawononga malirewo mofulumira kuposa zithunzi, chifukwa palibe chomwe chimatulutsidwabe. Ngati muli pamwamba pa izi, kusinthidwa kwa PNG kumayamba nthawi zambiri kumatha kukwanira - BMP ndi nthawi yambiri ya zaka makumi asanu ndi awiri a kukula kwa chithunzi chofanana ndi PNG.
Kodi Kusintha PNG idzachepetsa mtundu wa PNG images wanga?
+
Sichoncho. A lossless kuchokera round-trips bit-exactly, kotero ngati inu mosabisa akufuna kwa lossy kutuluka mtundu pixels amene anabwerera ndi pixels amene anapita mu. Izi ndi chifukwa chakuti zonse kutsatira ntchito mu izi banja pamene inu mwakhala kusinthidwa.
Nchifukwa chiyani malo osinthika amakono amayendetsa Kusintha PNG?
+
WEBP.to imapangidwa m'malo mwa m'badwo watsopano wazosankha zakale: mtundu umodzi womwe umachita kuwonongeka, kuwonongeka, alpha ndi animation, ndipo motsimikizika amalandiridwa pang'ono kuposa JPEG kapena PNG yomwe idachokera. Anthu amafika pano atasankha kuti zosasinthika zakale zimawawononga bandwidth, ndipo lamuloli limayambitsanso: mtundu uti, mtundu uti, zomwe zimachitika ndi kuwala. Kusintha PNG ndi pamodzi ndi kutsitsa ndi akaunti yomweyo, chifukwa chake mafunsowa amafunsidwa m'malo limodzi.
Pamene Kusintha PNG yatha, kodi ndi chiyani chomwe chimayenera kuchitika?
+
The Converter pa webusaitiyi amasintha zithunzi ndi kuchokera WebP, PNG, JPG ndi AVIF, amene ndi pamene inu musankhe ngati ochepa wapamwamba ndi woyenera kuwononga zakale masamba. Kuchita izi m'njira imeneyi ndi chinthu chofunikira: kusankha pixels koyamba ndi chotengera pambuyo pake, chifukwa chonyamula ndi chisankho chotsika mtengo ndipo pixels ndi mtengo wotsika mtengo.
Kodi masamba a sibling amayendetsa chinachake chosiyana?
+
Magalimoto ndi ofanana - mabuku ofanana, ogwira ntchito, ofanana. Zosiyana ndi zomwe zilipo, ndipo malingaliro ali pano ali pazinthu za mtunduwu zomwe zilipo: .webp yofanana yowonjezera imatha kunyamula VP8 yowonongeka, yopanda kusowa, kapena animation, kotero njira yogwiritsira ntchito yoyenera imasankhidwa pa fayilo kuposa pa kuwonjezera.
Kodi chimachitika chiyani kwa fayilo yanga, ndipo kodi ndiyenera kukhala ndi akaunti?
+
No akaunti, ndi chilichonse ndi kuikidwa: kutsitsa ndi kuchotsa kuchokera ogwira ntchito nthawi yochepa pambuyo ntchito amamaliza, ndi chilichonse ndi kuyendera, mnda kapena indexed. akaunti zilipo kwa mbiri ndi magulu kukula kokha.
