Indlela yokuguqula BMP kuya TIFF

Isinyathelo 1: Layisha eyakho BMP amafayela usebenzisa inkinobho engenhla noma ngokuhudula bese uphonsa.

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

Isinyathelo 3: Landa i-version yakho TIFF amafayela

BMP kuya TIFF Imibuzo Evame Ukubuzwa Yokuguqulwa

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

Layisha phezulu ihele lakho BMP futhi umguquli ufaka ukulungisa umgangatho okwaziyo ifomethi ye TIFF. U TIFF ongalahleki (PNG, TIFF, BMP) wonke ama-pixel agcinwa; u TIFF ongelahleki (JPG, WebP) ungahlela umphumela womgangatho ngaphambi kokufaka ngezansi. I-BMP igcina imiqulu ye-pixel engacindezelwanga ngokuphelele ngesihloko esincane, ngakho-ke kulula ukuyihlukanisa. I-TIFF iyindawo yokuqoqa engaphezu kwe-codec: ingagcina idatha engacindezelwanga, i-LZW, i-ZIP noma i-JPEG, kuze kube yi-32 bits ngasinye, ngekhasi eliningi kwifayela elilodwa.

Ingabe ngizothola ukubukeka okucacile uma isithombe si TIFF?

I-TIFF isekela le fomethi, kodwa ukuguquka akukwazi ukuyenza. I-BMP ayinaso isixhumi se-alpha, ngakho wonke ama-pixels kufaka phakathi isizinda sifika sigcwele. Sebenzisa /removebackground/ ngemuva kokususa isithako — bese i-alpha channel TIFF inikeza into egcinwa. I-TIFF iphatha i-CMYK, 16-bit ububanzi, i-ICC ifaka amaprofayili namadokhumende amakhasi amaningi, okuwukuthi okuthile okudingekayo ukuphrinta nokugcinwa kwemisebenzi.

Ingabe kukhona okulahlekile ekushintsheni phakathi kwe BMP ne TIFF?

Akukho data ye-pixel, cha. Ifomethi zombili zigcina isithombe ngaphandle kokucindezeleka okulahlekile, ngakho isithombe esiphumayo sifana nesinye esingene ngaphakathi futhi ukuguqulwa kungaphinda kwenziwe ngaphandle kweso. Okunye okushintshayo yisayizi yefayela, futhi okunye okuphawulekayo ukushayela — ububanzi bombala, amaprofayili afakwe, ama-layers kanye nobuciko bonke baxhaswa ngokuhlukile phakathi kwefomethi engalahleki.

Ingabe ukuguqulwa BMP kuya ku TIFF kugcina ukubukeka okucacile?

Ukubukeka okucacile kuhlala lapho TIFF i-PNG, WebP, TIFF, GIF, noma i-SVG. Ukushintsha ku-JPG kuhlanganiswa isixhumi se-alpha esibhekene nesizinda esimhlophe. Uma ufuna ukubukeka okucacile esinqumweni, bheka ukubonakala okucacile okuqaphelayo TIFF endaweni ye TIFF=JPG. I-TIFF iyifomethi yefayela lesithombe ephawulwe kusukela ngo-1986, futhi iyifomethi yokuskena, ukushicilela kanye nokugcinwa kwezinto eziphilayo ezijwayelekile.

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

Amaprofayili wemibala we-ICC afakwe ngaphakathi afundwa kusuka ku-BMP futhi axhunywe kabusha ku-TIFF lapho ifomethi ixhasa khona (JPG, PNG, TIFF, WebP). Amafomethi ngaphandle kwe-inkxaso yeprofayili abuyela emuva ku-sRGB, ogcina amamibala ahambisanayo phakathi kweziboniso eziningi ezimanje.

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

Ikhamera EXIF (ISO, i-shutter, i-lens, i-GPS coords) igcinwa ngokuzenzakalela ngesikhathi BMP → TIFF lapho amafomethi amabili exhasa i-metadata. Sebenzisa ukhetho lokufihla ukususa i-metadata ngaphambi kokulayisha ngezansi uma ufuna ukuhlanganisa izithombe ngaphandle kokubeka indawo.

Ingabe ngingenza ukuguqulwa kwe-batch kwe-BMP amafayela amaningi ku-TIFF ngasikhathi sinye?

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

Ingabe BMP kuya ku TIFF iqhathaniswa kanjani ne-Photoshop / GIMP ngemisebenzi efanayo?

Ukuguqulwa kwefomethi eqondile sisebenzisa i-libpng / libjpeg-turbo / libwebp / ImageMagick pipes efanayo umhleli wedesktop asebenzisayo, ngekhwalithi yokuphuma efanayo. Ushintsho luyi-batch management ehambisanayo — ama-desktop apps avula ifayela elinye ngasikhathi sinye; sivuma i-batch.

Yini isixazululo sehele lami TIFF?

Iphutha ngu 1:1 — TIFF yakho igcina ama-pixels ama-dimensions we-BMP. Uma ufuna ukushintsha ubukhulu njengengxenye yokuguqulwa, sebenzisa /resize-image/ ngemuva kokuguqulwa, noma uyibeke nge /image-resize/ utility.

Ingabe i TIFF ingaba ncane ngaphandle kwezinto ezibonakalayo ezibonakalayo?

Nge-JPG / WebP, umgangatho 75-85 uvame ukuthola i-TIFF 60-80% encane kuna-BMP ngaphandle koshintsho olubonakalayo emgwaqweni wokubuka ojwayelekile. Nge-lossless TIFF (PNG, TIFF), cabanga ukulondoloza okuncane — ngokuvamile 5-30% nge-deflate / LZW yokucindezela okungcono.

Ingabe amafayela ami BMP afihlakele ngesikhathi sokuguqulwa?

Yebo — amafayela alayishwe phezulu BMP aqhubekelwa phambili emisebenzini ehlukanisiwe futhi acishwe ngaphakathi kwemizuzu. Asikwazi ukufunda, ukugcina isikhathi eside, noma ukuhlanganisa idatha ye-pixel. Ifasitela eligcwele lokugcinwa libhalwe ku /privacy/.

Ingabe i-BMP kuya ku-TIFF isebenza ngezithombe ezinkulu kakhulu (50MP+)?

Yebo, mahhala kuze kube yi-100 MB. I-Premium iphatha izingeniso ezinkulu (300 MB+) kanye ne-exotic per-pixel depths (16-bit PNG, 32-bit float TIFF). Ipayipi lisakaza imibhalo ukuze umsebenzisi wememori alinganise ngokubalwa kwemibhalo, hhayi inani eliphelele le-pixel.

BMP

Amafayela e-BMP agcina izithombe ngefomethi ye-bitmap engacindezelwanga, okuholela osayizi bamafayela abakhulu kodwa ikhwalithi ephelele.

TIFF

Amafayela e-TIFF asekela ukujula kwe-bit ephezulu kanye nokucindezelwa okungenakulahlekelwa, okulungele ukuthwebula izithombe zobungcweti kanye nokuphrinta.
