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. 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 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. I-BMP yi-Windows Bitmap, ifomati ye-raster egqityiweyo eyenziwe kwi-Windows ukusukela ngo-1985.

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

Kwiziguqulelo ezininzi, iimayile ze-EXIF zekhamera ezinjengemodeli yekhamera kunye nendawo ye-GPS azithunyelwe kwi-BMP. Akukho mmiselo kule phepha ukugcina okanye ukususa i-metadata, ngoko khangela isiphumo ngombonisi we-metadata ukuba kubaluleke.

Ndingaguqula iifayili ezininzi PNG zibe BMP ngaxeshanye?

Iifayile ezininzi kumsebenzi omnye zifuna inkqubo ehlawulweyo. Ukusetyenziswa okukhululekileyo yifayile enye ngoguqulelo, uguqulelo olunye ngeyure. Kwinkqubo ehlawulweyo ungadibanisa iifayile ezininzi kumsebenzi omnye, emva koko ulayishe impumelelo nganye kwiyo okanye zonke kwi ZIP enye.

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 iifayile zam PNG zifihlakeleyo ngexesha lokuguqulwa?

Ewe. Iifayile ezilayishwe phezulu ze PNG ziqhubekekiswa kwiseva yethu yokuguqula, akukho mntu ujonge phezulu, kwaye azisasazwanga. Ukukhuphela kunye nokuguqulwa kwe BMP kususwa ngokuzenzekelayo malunga neyure ezili-24 emva kokuguqulwa, oshiya ixesha lokulayisha ezantsi iziphumo. Bona /privacy/ kwinkqubo epheleleyo.

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. I-PNG yifomati yomfanekiso ophantsi: umfanekiso ogciniweyo njenge-PNG uhlala ukhulu ngeeyure ezisixhenxe ukuya kwezilishumi kunemifanekiso efanayo njenge-JPG okanye i-WebP. I-BMP inamandla amakhulu — umfanekiso we-12-megapixel ujikeleze i-36 MB — kwaye akukho mkhangeli zincwadi uyamphatha njengefomati yewebhu esebenzayo.

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.
