PNG ukuba BMP Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-PNG ibe yi-BMP ngaphandle kokulahlekelwa umgangatho womfanekiso?

Layisha phezulu ifayili yakho ye PNG, emva koko umguquli wethu ufaka ukuphuculwa komgangatho owaziyo wefomati ye-BMP imveliso. Kwifomati ezingalahlekiyo (PNG, TIFF, BMP) sigcina zonke ii-pixels; kwifomati ezilahlekiyo (JPG, WebP) ungalungisa isizathu somgangatho phambi kokukhuphela.

Ingaba ukubonakaliswa okubonakalayo kuya kuqhubeka nokutshintsha PNG ukuya ku BMP?

Hayi - BMP ayinasiqhagamshelanisi se-alpha, ngoko imimandla ecacileyo idityaniswe nombala wokungasemva, omnyama ngaphandle kokuba uyitshintshile. Oku kubangela uxinzelelo oluqhelekileyo oluthile kule kuguqulelo: ilogo ebonakala icocekile kwiphepha elimnyama lifika ngebhokisi emhlophe ejikelezayo. Misela umbala omnyama ukuze uthelekise apho umfanekiso uhlala khona, okanye khetha injongo egcina i-alpha. I-BMP inamandla amakhulu — umfanekiso we-12-megapixel ujikeleze i-36 MB — kwaye akukho mkhangeli zincwadi uyamphatha njengefomati yewebhu esebenzayo.

Ingaba kukho into elahlekile ekuguquleni phakathi kwe PNG ne BMP?

Akukho data yepixel, hayi. Zonke iifomati zigcina umfanekiso ngaphandle koxinzelelo olulahlekileyo, ngoko ke umfanekiso ophumayo ufana nowo waya ngaphakathi kwaye uguqulelo luyaphinda uphinde luphinde. Okutshintshayo kubungakanani befayili, kwaye oku kusebenza ukuhamba - ubunzulu bombala, iiprofayili ezifakelweyo, amanqanaba noopopayi bonke baxhaswa ngokungalinganiyo phakathi kwefomati ezingalahlekileyo. I-PNG isebenzisa uxinzelelo lwe-DEFLATE ngaphezulu kwamagqabantshintshi okuskena acociweyo, ngoko ke i-pixel nganye ihlala ngokuchanekileyo, kunye ne-8-bit epheleleyo ye-alpha channel. I-BMP igcina imiqolo ye-pixel engacinezelwanga ngokupheleleyo enesihloko esincinci, oko kukuthi, yintoni eyenza kube lula ukuchaza ngeenkcukacha.

Ingaba uguqulelo PNG ukuya ku BMP lugcina ukubonakala ngaphaya?

Ukubonakala ngaphaya kuqhubeka xa usiya kwi-PNG, WebP, TIFF, GIF, okanye SVG. Ukutshintsha kwi-JPG kugubungela isiqhagamshelanisi se-alpha phantsi kwesiqalo esimhlophe - ukuba ufuna ukubonakala ngaphaya, cwangcisa ifomati eyaziyo ukubonakala ngaphaya endaweni ye-BMP.

Ingaba i-inkangeleko yam yombala (sRGB / Adobe RGB / CMYK) iya kuhlala i PNG ukuya ku BMP?

Iiprofayili zombala we-ICC ezifakelweyo zifundwa kumvelaphi PNG kwaye zidityaniswe kwakhona kwi-BMP yemveliso apho ifomati ixhasa khona (JPG, PNG, TIFF, WebP). Iifomati ezingaxhaswanga zibuyela kwi-sRGB.

Yintoni malunga ne-EXIF metadata xa uguqula PNG ukuya ku BMP?

I-EXIF yekhamera (ISO, i-shutter, i-lens, i-GPS) igcinwa ngokumiselweyo ngexesha lokuguqulwa kwe-PNG → BMP xa zombini iifayili zixhasa i-metadata. Sebenzisa ukhetho lobumfihlo ukususa i-metadata phambi kokukhuphela ukuba ufuna ukuthumela imifanekiso ngaphandle kolwazi lwendawo.

Ndingaguqula izigidi zeefayili PNG zibe BMP ngaxeshanye?

Ewe — tsala iifayile ezininzi PNG kwindawo yokulayisha kwaye sizibeke kwifolokhwe ngokuthe tye. Abasebenzisi abakhululekileyo bafumana i-100MB ngefayili nganye; i-Premium ayinasiphelo sefayili nganye kwaye iqhuba abasebenzi abathe tye abaninzi, ngoko ke iqela lemifanekiso engama-200 ligqiba ngaphantsi kwemizuzu emibini.

I-PNG ukuya kwi-BMP ithelekiswa njani ne-Photoshop / i-GIMP kumsebenzi ofanayo?

Uguqulelo lwefomati olulula siqhuba i libpng / libjpeg- turbo / libwebp / ImageMagick imibhobho efanayo umhleli we desktop usebenzisa, ngexabiso elifanayo. Utshintsho luyizinto ze desktop zivula ifayile enye ngexesha; siyamkela iqela kwaye siqhuba ngokuthe tye.

Ingaba i-BMP iya kuba nesisombululo esinjani na?

Ukuziphatha okungagqibekanga kuku-1:1 — i-BMP yakho yemveliso inezinto ezilinganayo ze-pixels njenge-PNG. Sebenzisa /resize-image/ inyathelo elahlukileyo emva kokuguqula ukuba ufuna ukunyusa okanye ukunyusa i-scale njengenxalenye yokuhamba komsebenzi.

Ingaba i BMP ifayili incinane kangakanani na ukuba ayinazo izinto ezibonakalayo ezibonakalayo?

Kwi-JPG / WebP, umgangatho we-75-85 ufumana ifayili i-60-80% incinane kune-PNG yomthombo ngaphandle kotshintsho olubonakalayo kumgama wokujonga oqhelekileyo. Kwiinjongo ezingalahlekiyo (PNG, TIFF), lindele ukonga okuncinci — ngokuqhelekileyo 5-30% nge-deflate / LZW yokucinezela engcono.

Ingaba iifayile zam PNG zifihlakeleyo ngexesha lokuguqulwa?

Ewe — iifayile ezilayishwe phezulu PNG ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe kwimizuzu. Asizukufunda, sigcine, okanye sisebenzise i-pixel data. Inkqubo yobumfihlo obupheleleyo kunye nefestile yokugcina ibhalwe kwi /privacy/.

Ingaba i-PNG ukuya kwi-BMP iguqula imifanekiso enkulu kakhulu (50MP+)?

Ewe, simahla ukuya kwi-100MB. I-Premium iphatha izingeniso ezinkulu (300MB+) kunye nobunzulu obukhethekileyo kwi-pixel nganye (16-bit PNG, 32-bit float TIFF). I-pipeline isasaza imiqolo ye-pixel, ngoko ke ukusetyenziswa kwememori kulinganiselwa ngobalo lomqolo, hayi ubalo lwe-pixel jikelele.

PNG

Iifayile zePNG zixhasa ukucaca kwaye zisebenzisa ucinezelo olungenalahleko, nto leyo ezenza zilungele imifanekiso, iilogo, kunye neeskrini.

BMP

Iifayile zeBMP zigcina imifanekiso kwifomathi yebitmap engacinezelwanga, nto leyo ebangela ukuba iifayile zibe nkulu kodwa zibe nomgangatho ogqibeleleyo.
