Indlela yokuguqula BMP ukuba PNG

Inyathelo 1: Rhweba ngaphakathi BMP iifayili usebenzisa iqhosha phezulu okanye nge shift nendawo.

Inyathelo 2: Nqakraza kwiqhosha 'Uguqulo' ukuqala uguqulo.

Inyathelo 3: Gcina ifayile yakho eguqulweyo PNG iifayile

BMP ukuba PNG Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayili yakho ye BMP, emva koko umguquli wethu usebenzise ukuphuculwa komgangatho owaziyo-fomati yemveliso ye PNG. Iifomati ezingalahlekiyo (PNG, TIFF, BMP) sigcina zonke ii-pixels; iifomati ezilahlekiyo (JPG, WebP) ungalungisa isizathu somgangatho phambi kokukhuphela.

Ingaba ukuguqulwa kwe-BMP ukuya kwi-PNG kugcina ukubonakala ngaphaya?

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

Ingaba i-inkangeleko yam yombala (sRGB / Adobe RGB / CMYK) iya kuqhubeka iphila BMP ukuya kwi-PNG?

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

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

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

Ndingaguqula iimawaka eefayili ze-BMP zibe yi-PNG ngaxeshanye?

Ewe — tsala iifayile ezininzi ze BMP 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-BMP ithelekiswa njani ne-PNG kwi-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.

Yintoni isisombululo kunye nemilinganiselo yefayili yam ye-PNG?

Ukuziphatha okungagqibekanga kuku-1:1 — i-PNG yakho ivelisa i-pixels ezilinganayo njenge-BMP. Ukuba ufuna ukuguqula ubungakanani njengenxalenye yokuguqula, sebenzisa i-/resize-image/ isixhobo emva kokuguqula, okanye uyibeke kwi-/image-resize/ utility.

Ingaba incinci kangakanani ifayili ye-PNG ngaphandle kwee-artifacts ezibonakalayo?

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

Ingaba iifayile zam ze-BMP zifihlakeleyo ngexesha lokuguqulwa?

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

Ingaba i-BMP ukuya kwi-PNG iguqulela isebenza kwimifanekiso emikhulu 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 ngobalo lwe-pixel jikelele.

Kutheni ifayili yam eguqulweyo PNG incinci/ikhulu kuneleyo ndiyifumeneyo?

Ifayili ye-BMP enesicitho esinamandla (umzekelo, i-JPG enesicitho esiphezulu) ihlala ikhula xa iphinde ikhowudiwe ibe yi-PNG (PNG, TIFF) engenasicitho, kwaye i-BMP enesicitho esiphezulu se-bitrate ihlala incinci kakhulu xa ihamba kwi-JPG/WebP. Uthelekiso luxhomekeke kwizinto eziqulethe umfanekiso (iifoto zicitha ngokuhlukileyo kunemizobo yelayini).

Ndingayisebenzisa ifayili eguqulweyo PNG ngemali?

Ewe. Uguqulelo lutshintsho lwefomati - ilungelo lokushicilela kwimixholo yomfanekiso lihlala kuwe (okanye umntu ophetheyo kumgca womthombo BMP). Sidibanisa akukho phawu lwamanzi, akukho phawu lwemetadata, kwaye sicela akukho layisensi ngaphezulu kwemveliso.

BMP

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