BMP Amathuluzi

Tshintsha BMP kuya futhi kusuka kumafomethi ahlukahlukene

Mayelana BMP

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

BMP Imibuzo Evame Ukubuzwa Yokuguqulwa

Yini ihele le-BMP?

I-BMP iyifomethi yesithombe se-raster engalahlekelwa yisimo esigcina wonke ama-pixel ngaphandle kokucindezeleka. I-BMP ilungele kakhulu ukuthwebula izithombe, umdwebo we-line, ukudweba ngemiphetho eqinile kanye nanoma iyiphi isithombe esizoguqulwa. I-BMP ayidingi i-decoder library ngaso sonke isikhathi, ngakho ihlala i-format ephephile yokushintshana yezinhlelo ezifakwe ngaphakathi neWindows ezidala.

Ingabe kukhona okulahlekile uma i-BMP iguqulwa ibe yifomethi engekho emthethweni?

Akukho data ye-pixel. BMP igcina isithombe ngokugcwele ngaphezu kokuyifinyelela, ngakho ukuguqulwa phakathi kwefomethi ezimbili ezingalahleki kubuyiselwa emuva futhi kungaphinda kwenziwe ngaphandle kokulahlekelwa. Okungakwazi ukulahleka yizinto zonke ezingaphansi kwe-pixels — amaprofayili wemibala, ukubukeka okucacile, ukubukeka, i-metadata efakwe — ngoba usizo lwalezi luhluka kakhulu phakathi kwefomethi kune-pixel storage. I-BMP igcina imiqulu ye-pixel engacindezelwanga ngokuphelele ngesihloko esincane, ngakho-ke kulula ukuyihlukanisa.

Kungani umshicileli wami wesithombe egcina BMP?

Ngenxa yokuthi iyifomethi i-platform yo Recorder ikhophi ngokusemthethweni, ngakho ukuqoqa kuthatha imali encane ngaphandle kokuqhubekela phambili uma imishini isebenza ukwenza okuthile. Kuyinketho efanele ngesikhathi so Recording futhi kunzima ngemuva - ihele lidinga ukushintshwa ngaphambi kokuba lihlukaniswe, liguqulwe noma lifakwe kuphi ngaphandle kwendlela eyenza ngayo. I-BMP yiWindows Bitmap, ifomethi ye-raster engaqondakali efakwe ku-Windows kusukela ngo-1985.

Kungani isizinda sami esicacile sishintsha sibe mhlophe ku BMP?

Ngenxa yokuthi BMP ayinaso isixhumi se-alpha sokugcina. I-pixel ngayinye kufanele ibe nombala oqinile, ngakho ukubukeka okucacile kuhlanganisene nendawo yangaphambili - okumhlophe ngokuzenzakalela - ngesikhathi ihele libhalwe. Akukho okuzobuyiselwa emuva. Uma isithombe sidinga ukuhlala kwikhasi elimnyama noma ngaphezulu kwesithombe, guqula kube yifomethi egcina ukubukeka okucacile endaweni. I-BMP iyinto enkulu—isithombe esingu-12-megapixel siyizi-36 MB—nakho akukho isiphequluli esiyiphatha njengefomethi yewebhu efanele.

Ingabe kufanele ngigcine amafayela amasha njenge BMP?

Uma nje kukhona okuthile okudingayo. Ifomethi ivuliwe, futhi akukho sidingo sokushintsha ingobo yomlando ongeke ukwenze kube nzima, kodwa akuyona indawo lapho ithuluzi noma umphumela uhamba khona. Kunoma yini entsha, ifomethi yamanje ayidingi lutho olungeziwe futhi ivimbela ukulandelana kwesifundo seminyaka emincane kusukela manje.

Ingabe kubaluleke ukuthi BMP ingaphezu kweminyaka engu-30?

Ubudala bukhona akuyona inkinga - amafomethi amaningi onyaka akhona alungile, ngokucacile ngoba konke kudlule iminyaka eminingi ukuwafaka. Okubalulekile ukuthi unyaka uthathe isinqumo: amafayela amancane, amaprosesa aphansi, akukho nethiwekhi, futhi ayikho into edingayo. lapho athathe isinqumo khona, ifomu lilungile. lapho akwenzeki khona, yilokho okubangela ukudluliswa.

Ingabe BMP yifomethi yeMicrosoft edinga isofthiwe yeMicrosoft?

Kuvela kuMicrosoft, futhi lapho uxhumano luphela khona. Akukho sicelo esiqalayo esilahlekile futhi akukho layisense elingagcinwa: isitayela sashicilelwa, silula kakhulu njengoba ifomethi yefayela ithola, futhi yonke indlela yokusebenza nethuluzi lifunde futhi libhale iminyaka eminingi. Okunye okuguqula kuyo yisayizi nezici, awukwazi ukufinyelela.

Kungani i-BMP ingabonisi kwisiphequluli sami?

Ngenxa yokuthi iziphequluli zisebenzisa uhlu oluncane lwefomethi yesithombe futhi BMP ingaphandle kwayo — ihlobene nokuhlola, uphrinta noma ukuguqulwa komsebenzi ohambayo ngaphezu kwe-web. Ihele alilahleki; lingenakho umbhalo oguqula ikhasi. Ukushintsha isithombe sefomethi yewebhu-ejwayelekile kuyindlela yokulungisa ehamba phambili futhi kuvame ukwenza ihele libe ncane kakhulu.

Ngabe kufanele ngiguqule i-BMP ibe yifomethi ehlukile?

Guqula i-BMP ibe yi-JPG noma i-WebP uma isihloko sivuliwe kwi-webu noma i-imeyili, lapho ubukhulu befayela elincane libalulekile kune-pixel ngayinye.

Ingabe ukushintsha i-BMP kuzonciphisa ikhwalithi yesithombe?

Uma uguqula i-BMP ibe yifomethi engekho emthethweni, ama-pixels agcinwa ngokugcwele. Uma uguqula i-BMP ibe yifomethi engekho emthethweni njenge-JPG, umbhalo-mbhalo ungenza ubukhulu-no-umgangatho-ubukhulu-ubukhulu-ushintsho-ukulawula nge-settings ye-output quality.
