Indlela yokuguqula PNG ukuba BMP

Inyathelo 1: Layisha eyakho PNG iifayile usebenzisa iqhosha elingasentla okanye ngokutsala nokuwisa.

Inyathelo lesi-2: Cofa iqhosha elithi 'Guqula' ukuze uqalise ukuguqula.

Inyathelo lesi-3: Khuphela i-converted yakho BMP iifayile

PNG ukuba BMP Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayili yakho ye PNG kwaye umguquli usebenzise ukuphuculwa komgangatho owaziyo ifomati ye BMP. Kwifomati engalahlikiyo BMP (PNG, TIFF, BMP) yonke i-pixel igcinwa; kwifomati elahlayo BMP (JPG, WebP) ungalungisa umgangatho phambi kokukhuphela.

Ingaba uguqulelo PNG ukuya ku BMP lugcina ukubonakala ngaphaya?

Ukubonakala ngaphaya kuqhubeka xa BMP yi-PNG, WebP, TIFF, GIF, okanye SVG. Ukutshintsha ukuba yi-JPG kwenza ukuba isiqhagamshelanisi se-alpha sifane nesiqalo esimhlophe. Ukuba ufuna ukubonakala ngaphaya kwiziphumo, cwangcisa ukubonakala ngaphaya okuziyo BMP endaweni ye-BMP=JPG.

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

Iiprofayili zombala we-ICC ezifakiwe zifundwa ukusuka kwi-PNG kwaye zidityaniswe kwakhona kwi-BMP apho ifomati ixhasa khona (JPG, PNG, TIFF, WebP). Iifomati ngaphandle koxhaso lweprofayili zibuyela kwi-sRGB, egcina imibala ihambelana nakwimboniselo ezininzi zexesha elidlulileyo.

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

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

Ndingaguqula iifayili ezininzi PNG zibe BMP ngaxeshanye?

Ewe — tsala iifayile ezininzi PNG kwindawo yokulayisha kwaye sizibeke kwifolokhwe ngokuthe tye. Abasebenzisi abakhululekileyo bafumana i-100 MB 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 ethe ngqo siqhuba i libpng / libjpeg- turbo / libwebp / ImageMagick imibhobho efanayo umhleli we desktop ayisebenzisayo, ngemveliso elinganayo. Utshintsho luyinkqubo ethe tye ethe tye - iinkqubo ze desktop zivula ifayile enye ngexesha; siyayamkela iqela.

I-BMP ifayile yam izakuba nesisombululo esingakanani?

Okumiselweyo yi-1:1 — i-BMP yakho igcina ubungakanani be-pixels yombhalo ovela ku-PNG. Ukuba ufuna ukuguqula ubungakanani njengenxalenye yokuguqula, sebenzisa i-/resize-image/ emva kokuguqula, okanye uyibeke kwi-/image-resize/ utility.

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

Kwi-JPG / WebP, umgangatho we-75-85 ufumana i-BMP 60-80% encinci kune-PNG ngaphandle kotshintsho olubonakalayo kumgama wokujonga oqhelekileyo. Kwi-BMP engalahliyo (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 ixesha elide, okanye sisebenzise i-pixel data. Ifestile yokugcina epheleleyo ibhalwe kwi /privacy/.

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

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

Kutheni i-BMP yam eguqulweyo incinci okanye ikhulu kuneleyo ndiyifumeneyo?

A PNG nge-compression enamandla ekhoyo (i-lossy JPG) ihlala ikhula xa i-encoded kwakhona kwi-lossless BMP (PNG, TIFF). I-lossless PNG ihlala ikhula ngokugqithisileyo xa ihamba kwi-JPG / WebP. Uthelekiso luxhomekeke kwizinto eziqulethe umfanekiso — iifoto zicofa ngokuhlukileyo kunemizobo yelayini.

Ndingasebenzisa i-BMP eguqulweyo ngentengiso?

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

PNG

Iifayili ze-PNG zihambelana nobunzulu obubonakalayo kwaye zisebenzisa ukucinezela okungalahleki, zenza ukuba zilungele amagrafiki, ilogos, kunye nemifanekiso yekhusi.

BMP

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