Isinyathelo 2: Chofoza inkinobho ethi 'Guqula' ukuze uqale ukuguqulwa.

Isinyathelo 3: Landa i-version yakho BMP amafayela

PNG kuya BMP Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani i-PNG ibe yi-BMP ngaphandle kokulahlekelwa ubuhle besithombe?

Layisha phezulu ihele lakho PNG futhi umguquli ufaka ukulungisa umgangatho okwaziyo ifomethi ye-BMP. Kuzo zonke izimo ezingenalutho (PNG, TIFF, BMP) wonke ama-pixel agcinwa; kuzo zonke izimo ezingenalutho (JPG, WebP, AVIF) ungalungisa umphumela womgangatho ngaphambi kokufaka ngezansi.

Ingabe ukuguqulwa PNG kuya ku BMP kugcina ukubukeka okucacile?

Ukubukeka okucacile kuhlala lapho uhamba ku-PNG, WebP, TIFF, GIF, noma SVG. Ukushintsha ku-JPG kuhlanganiswa isixhumi se-alpha esibhekene nesizinda esimhlophe - uma ukubukeka okucacile kubaluleke kakhulu kukusetshenziswa kwakho (i-web overlays, ilogos), bheka ifomu elikwaziyo ukubukeka okucacile endaweni ye BMP = JPG.

Ingabe iprofayili yami yombala (sRGB / Adobe RGB / CMYK) izohlala i PNG kuya ku BMP?

Amaprofayili wemibala we-ICC afakwe ngaphakathi afundeka kusuka ku-PNG futhi axhunywe kabusha ku-BMP lapho ifomethi ixhasa khona (JPG, PNG, TIFF, WebP). Amafomethi ngaphandle kwe-insiza yeprofayili abuyela emuva ku-sRGB. Umsebenzi we-Print-shop CMYK uhamba ngokuqondile nge-TIFF ne-high-bit JPG.

Yini mayelana ne-EXIF metadata uma uguqula PNG usuka ku-BMP?

Ikhamera EXIF (ISO, i-shutter, i-lens, ama-GPS coordinates) igcinwa ngokuzenzakalela ngesikhathi sokuguqulwa PNG → BMP lapho amafomethi amabili exhasa i-metadata. Sebenzisa ukhetho lokufihla ukususa i-metadata ngaphambi kokulayisha ngezansi uma ufuna ukuhlanganisa izithombe ngaphandle kokuveza indawo ye-geolocation noma idivayisi yokuqoqa.

Ingabe ngingenza ukuguqulwa kwekhulu le PNG amafayela ku BMP ngasikhathi sinye?

Yebo — cindezela amafayela amaningi PNG endaweni yokulayisha futhi sizowabeka emqoka ngokufanayo. Abasebenzisi abamahhala bathola kuze kube yi-100 MB ngefayela ngalinye; iPremium ayinaso isiphetho sefayela ngalinye futhi isebenza nabasebenza ngokufanayo, ngakho-ke isithombe esingu-200 siqediwe ngaphantsi kwemizuzu emibini.

Ingabe PNG kuya ku BMP iqhathaniswa kanjani ne-Photoshop noma i-GIMP kumsebenzi owodwa?

Ukuguqulwa kwefomethi sisebenzisa i-libpng / libjpeg-turbo / libwebp / ImageMagick pipes efana ne-desktop editor esebenzisa, ngekhwalithi ye-output efana. Ushintsho luyindlela yokusebenza - amathuluzi wedesktop aphatha ifayela elinye ngasikhathi sinye; sivumela iqembu futhi sisebenzisana nabo ku-server-side.

Yini isixazululo kanye nezici zehele lami BMP?

Ukuziphatha okuzenzakalelayo yi-1:1 — i-BMP yakho yesokudla inezici ezifanayo ze-pixel njenge-PNG. Ukushintsha ubukhulu njengengxenye yokuguqulwa, sebenzisa /ukuguqula-sithombe/ ngaphambi noma ngemuva kwalo inyathelo. Ukuxhuma kushesha kunalokho kokubuyisela emuva kubungakanani obusha ngaphakathi kwepayipi lokushintsha.

Ingabe ihele BMP lincane uma kungabonakali izinto ezibonakalayo?

I-JPG / WebP, ikhwalithi engu-75-85 idala ifayela elincincane ngama-60-80% kunalomthombo PNG ngaphandle koshintsho olubonakalayo emgwaqweni wokubuka ojwayelekile. Inhloso engalahleki (PNG, TIFF), cabanga ukulondoloza okuncane — ngokuvamile 5-30% nge-deflate / LZW yokucindezela engcono kunendawo yomthombo.

Ingabe amafayela ami PNG afihlakele ngesikhathi sokuguqulwa?

Yebo — amafayela alayishwe phezulu PNG aphathwa ngabasebenzi abahlukanisiwe futhi asuswa ngaphakathi kwemizuzu. Asikwazi ukufunda, ukugcina, noma ukuhlanganisa idatha ye-pixel. Inqubomgomo yobumfihlo obuphelele kanye nefasitela lokugcinwa kubhalwe ku /privacy/.

Ingabe i-PNG kuya ku-BMP isebenza ngezithombe ezinkulu kakhulu (50 MP nangaphezulu)?

Imahhala kuze kube yi-100 MB ngefayela ngalinye. I-Premium iphatha izingeniso ezinkulu (300 MB+) kanye ne-exotic per-pixel depths (16-bit PNG, 32-bit float TIFF). Ipayipi lisakaza imiqulu ye-pixel, ngakho-ke kusetshenziswa kwememori kulinganiselwa ngenani lemiqulu hhayi inani le-pixel jikelele — isithombe se-100-megapixel siguqulwa ngefomethi yomlando efanayo njenge-10-megapixel.

Kungani ihele lami eliguqulwe BMP likhulu noma lincane kunalokho engilindele?

Ihele PNG elinamandla okucindezeleka (JPG enamandla okucindezeleka) livame ukukhula uma liphinde likhodwe ku BMP (PNG, TIFF) okungenasici; i-bitrate ephezulu okungekho sici PNG livame ukuncipha kakhulu liya ku-JPG / WebP. Ukulingana kuxhomekeka kusithombe esiqukethwe — ama-photographs acindezeleka ngokuhlukile kakhulu ku-line art noma ama-screenshots.

Ingabe ngisebenzisa ifayela eliguqulwe BMP ngebhizinisi?

Yebo. Ukuguquka kuyisimo sokuguqulwa kuphela - ilungelo lokushicilela kusithombe sihlala kuwe (noma umuntu ophethe isithombe ku-PNG umsuka). Sifaka i-watermark, sifaka ama-pixels wokulandelela, futhi sicela i-license ngaphezulu kwe-BMP okuqukethwe.

PNG

Amafayela e-PNG asekela ukucaca futhi asebenzisa ukucindezela okungenakulahlekelwa, okwenza afaneleke kakhulu kuma-graphics, ama-logo, kanye nezithombe-skrini.
