PNG ukuba BMP Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-PNG ibe yi-BMP ye-web ekhoyo namhlanje?

Nciphisa ifayile yakho ye PNG kwi-picker kwaye i-encoder yethu ivelisa i-BMP output elungelelanisiweyo yonikezelo lwe-web: umgangatho we-factor 80 ngokumiselweyo (i-Lighthouse sweet-spot), indawo yombala echanekileyo, kunye nokwamkela-ukwazisa ukuphuma emva onokuthi uthuthe ngasemva kwe `<imifanekiso>` inxalenye ecaleni kwe-original PNG.

Ingaba i-BMP iya kuba ncinci kune-PNG?

Xa usuka kwi-PNG / JPG / TIFF usuka kwi-WebP okanye i-AVIF: lindele ukuba ibe yi-25-50% encinci kune-JPG kwixabiso elifanayo lokubona, 60-90% encinci kune-PNG. Ukuhamba ngenye indlela (i-WebP / AVIF ubuyela kwi-BMP = PNG / JPG) ngokuqhelekileyo ikhula ifayile kuba ushiya i-codec eyaziwayo ye-edala — esetyenziswayo ukuhambelana, hayi ubungakanani.

Ingaba i-PNG ukuya kwi-BMP igcina ukubonakala ngaphaya / i-alpha?

Ukubonakala ngaphaya kuqhubeka xa i-BMP ixhasa i-alpha (PNG, WebP, AVIF, GIF, TIFF, SVG). Ukutshintsha kwi-JPG kugubungela isiqhagamshelanisi se-alpha emdaka — ukuba ufuna ukubonakala ngaphaya kwi-web ekhawulezayo ye-WebP okanye i-AVIF endaweni ye-BMP.

Ndingagcina i-inkangeleko yam yombala (sRGB / Imboniselo P3) isuka kwi-PNG ukuya kwi-BMP?

Ewe kwi-BMP iifayili ezigcina iiprofayili ze-ICC (PNG, JPG, WebP, AVIF, TIFF). Iiprofayili zexesha eliphakathi ezifana ne-Display P3 zihamba rhoqo zidlula kwi-WebP ne-AVIF; iiprofayili ze-sRGB zihamba rhoqo zidlula kwi-BMP. Ukuba i-BMP ayikwazi ukugcina iprofayili, i-output iphawulwe nge-sRGB ukugcina iiseva ze-web zingazi.

I-BMP encoder ixhasa imimiselo yomgangatho olahlekile vs ongalunganga?

I-Lossy BMP (WebP / AVIF / JPG) ivuma ubunjani 1-100, okumiselweyo 80. I-Lossless BMP (PNG / WebP lossless / TIFF) ayithatheli umgangatho wokukhetha — i-pixel nganye igcinwa. I-WebP ne-AVIF ziifomati ezizimeleyo ezinokwenza nantoni na, nto leyo eyenza ukuba zibe ziinjongo ezifanelekileyo ze-BMP xa umthombo PNG uxuba iifoto nemifanekiso.

Ingaba uguqulelo lwe BMP luza kubonakala lufana no PNG kwiskrini se-Retina?

Kwi-quality 80+ kwi-WebP / AVIF utshintsho alubonakali kunoma ubani ngaphandle kwengqondo eqeqeshiweyo nakwi-3x isixhobo se-pixel ratio. Iifoto zicinezela ngokubonakalayo ngakumbi kunemizobo yomgca; ukuba i-PNG yakho yimifanekiso yekhusi okanye i-UI mockups, phakamisa umgangatho ukuya kwi-90 okanye sebenzisa i-BMP engalahlekiyo.

Ingaba i-PNG ukuya kwi-BMP igcina iifayili zoopopayi?

I-PNG ekhoyo (i-WebP ekhoyo, i-GIF, i-APNG) ihlala kuphela xa i-BMP ikwazi uopopayi (i-WebP ekhoyo, i-GIF, i-APNG). Ukutshintsha i-PNG ekhoyo ibe yi-BMP ehlalayo (i-PNG, i-JPG, i-AVIF ehlalayo) ivelisa kuphela isakhelo sokuqala — sebenzisa umguquli woopopayi okhethekileyo ukuba ufuna ukugcina zonke iisakhelo.

Ingaba i-EXIF metadata yekhamera iya kuqhubeka iphila PNG ukuya BMP?

Ewe ngokumiselweyo xa zombini i-PNG ne-BMP zixhasa i-EXIF (JPG, PNG, WebP, TIFF, HEIC). Imihlaba yekhamera (ISO, i-shutter, i-lens, i-GPS) ikhopiwe. Sebenzisa ukhetho lwe-"strip metadata" ukuba ushicilela kwi-web kwaye ufuna ukushiya ii-GPS coordinates phambi kokuba i-BMP ishiye isiphequluli sakho.

Ndingaguqula isiqulathi seefayili se-PNG kwi-BMP?

Ewe — shiya iifayile ezininzi ze PNG ngaxeshanye kwaye zikhowudiwe ngokuthe tye. Ii-akhawunti ezikhululekileyo: 100 MB ngefayili nganye. Ii-akhawunti ezizimeleyo zifumana abasebenza ngokuthe tye abaninzi kunye neentloko ezinkulu ngefayili nganye, ngoko ke i-200-image gallery ihlala igqiba kwimizuzu emibini.

Ingaba iifayile zam ze PNG zifihlakeleyo ngexesha lokuguqulwa kwe BMP?

Ewe - iifayili ezilayishwe phezulu ze PNG ziqhubekekiswa kubasebenzi ababekwe ngokuzimeleyo kwaye zicinywe kwimizuzu. Akukho kuhlaziyo lwabantu lwee-pixels, akukho kopisha kugcinwa, akukho qela lesithathu lifumana unikezelo. Bona /privacy/ kwifestile yokugcina echanekileyo.

Ndiyilungiselela njani i BMP nge PNG ekhuselekileyo kwiwebhusayithi yam?

Sebenzisa isiqalelo `<imifanekiso>`: `<imifanekiso><isiseko srcset="imifanekiso.BMP" type="imifanekiso/BMP"><img src="imifanekiso.PNG" alt=""></imifanekiso>`. Ii-browsers eziqonda i-BMP zifumana ifayili encinci; ii-browsers ezidala zibuyela kwi-PNG. I-WebP ixhaswa kwi-96%+ yee-browsers ezifakiwe, i-AVIF kwi-90%+.

Kutheni ifayili yam BMP ingalindelekanga ikhulu / incinci kuneleyo ndiyifumeneyo?

I-PNG esele icinezelwe kakhulu (i-JPG ephantsi-bunjani) ihlala ikhula xa iphinde ikhowudiwe ibe yi-BMP (PNG / TIFF) engalahlekiyo. I-PNG (PNG / TIFF) engalahlekiyo ene-bitrate ephezulu ihlala incinci nge-60-90% xa ihamba kwi-BMP (WebP / AVIF) eyaziwayo engalahlekiyo. Imixholo yomfanekiso ibalulekile — iifoto zicinezela ngokuhlukileyo kakhulu kunemizobo yelayini kunye nemifanekiso yekhusi.

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.
