Indlela yokujika BMP

1 Layisha phezulu i BMP images yakho uze ulinde ukujonga phambi koshicilelo ukuba kuvele.

2 Rhuqa ngaphandle ummandla ofuna ukuwugcina, okanye utshixe ukhetho kwi 1:1, 4:3 okanye 16:9 kwaye urhoxise ngokukhululekileyo ngaphakathi kolu hlobo loqhagamshelwano.

3 Qinisekisa ukutywina - i-rectangle efanayo isetyenziswe kwifayile nganye olayishe kuyo, oko kukuthi indlela emiselweyo ephelela ngokuhambelana ngokuqinisekileyo.

4 Layisha ezantsi ifayili ecutiweyo BMP, ngazo zonke izinto ezingaphandle kwesakhelo ezilahlekileyo.

Ukusika BMP Imibuzo ebuzwa rhoqo

Ingaba ifomati yam yombhalo itshintsha indlela eziphatha ngayo i-crop?

It can. I-BMP iqulethe imiqolo ye-RGB engacocwanga engacocwanga enesihloko esincinci, ngoko ke ayilahleki ngokupheleleyo kwaye ikhulu — rhoqo 10-20x ubungakanani bomfanekiso ofanayo njenge-PNG. That decides whether the crop is a pure pixel operation or whether the file has to be rebuilt around it.

Nantoni na ekhethekileyo kwi BMP ekufuneka ikwazi phambi kokuba ndityhale?

Ewe — kuba akukho nto icinezelweyo, i-BMP ikhawuleza ukufunda nokuhlela kodwa iphazamisayo ukulayisha, kwaye ayithuthi i-metadata yokugcina. Loluhlobo lweenkcukacha ezibonisa kuphela emva kokuba ubhale ngaphezulu okubhaliweyo okubhaliweyo.

I-Ukusika BMP ikhetha kwaye icima indawo njani?

Ngokucacileyo, i-pixel ethe nkqo okhetha yona ibhalwe ngokuthe ngqo ngaphandle kwakhona ngaphandle kokuphinda usebenzise ikhowudi, ngoko ke ukutywina umfanekiso ongenakulahleka kulungile kumazwe ahambelanayo okuqala, i-byte nge-byte. Urhoxisa ummandla ofuna ukuwubona ngokuthe ngqo kwimboniselo, okanye ubhale ngokuchanekileyo i-pixels ezihambelanayo ukuba sele uyazi.

Ndingatyhila njani i-aspect ratio?

Ewe. Tshixa ukhetho kwi 1:1, 4:3, 16:9 okanye nayiphi na i-ratio eyenziwe ngokwezifiso kwaye urhoxise ngokukhululekileyo ngaphakathi kolu thintelo - oko kukuthi, indlela ofumana ngayo iseti yemifanekiso elungele zonke i-slot yobeko olufanayo ngaphandle kokulinganisela nantoni na.

Ingaba isiqhagamshelanisi se-alpha sihlala?

Ewe. I-PNG ne-TIFF zithatha isiqhagamshelanisi esipheleleyo se-8-bit alfa kwaye zigcinwa ukusuka kwisiphelo ukuya kwisiphelo. Ziphathaniswa kuphela ukuba ujonge ubungakanani obungena-alpha, apho ii-pixels ezicacileyo zidityanisiwe kumbala omnyama.

Yintoni endinokuyilayisha kwi Ukusika BMP?

PNG, BMP ne TIFF ziifomati zeraster ezingalahlekiyo eziphatha ngokuthe ngqo, kwaye amacebo alahlekiyo (JPG, WebP, GIF) asebenza kakuhle ukuba ufuna ukuba zikwiqela elifanayo. I-TIFFs yephepha elininzi ifunyenwe kwaye iphathwa iphepha ngalinye.

Ingaba kukho umda wobungakanani befayili kwi Ukusika BMP?

Ewe: ii-akhawunti ezikhululekileyo ziqhubekeka imifanekiso ukuya kwi-5 MB nganye; amacebo angenangxaki abetha loo mgangatho kuqala kunemifanekiso, kuba akukho nto igqityiwe. Ukuba ugqithile kuyo, ukujika kwi-PNG kuqala kuninzi kakhulu ngokwaneleyo - i-BMP ihlala ilishumi ukuya kwezilishumi elinambini iphindaphindo lobungakanani bomfanekiso ofanayo njenge-PNG.

Ingaba i Ukusika BMP iya kunyusa ubunjani be BMP images yam?

Hayi. Umcebo ongenakulahleka ujikeleza- uhambe ngebithi- ngokuchanekileyo, ngoko ukuba awufuni ngokucacileyo ufomati yemveliso engalahlekiyo ii pixels ezibuyela umva zii pixels eziye zaphuma. Le yisizathu esipheleleyo sokugcina usebenza kulo sapho ngelixa uqhubeka uhlela.

Kutheni i-site ekwifomati entsha iqhuba Ukusika BMP?

WEBP.to ibekwe phantsi kotshintsho olutsha lwezo zombini iinkqubo ezingagqibekanga: ifomati enye eyenza ilahlekile, engalahleki, i-alpha kunye nobuchule, kwaye ihlala incinci kune-JPEG okanye i-PNG eyavela kuyo. Abantu bafika apha begqibe ukuba iimfuno eziqhelekileyo zakudala zibiza ibhandewidth, kwaye loo sinqumo sikhupha ngokuzenzekelayo isiphelo: ubungakanani obunjani, umgangatho onjani, into eyenza ukuba ibonakale. Ukusika BMP ikwi-upload efanayo ne-akhawunti efanayo ukuze ezo mibuzo ziphendulwe kwindawo enye.

Xa i Ukusika BMP iphumeze, yintoni ekufuneka yenziwe emva koko?

Umguquli kule ndawo uhambisa imifanekiso ukuya nakwi WebP, PNG, JPG ne AVIF, apho ugqiba khona ukuba ifayile encinci ifanele ilahle iiseva ezidala. Ukwenza oku ngokulandelana okubalulekileyo: khetha ii-pixels kuqala kwaye isiqulathi-zifayili emva koko, kuba isiqulathi-zifayili sigqibo esiphantsi kwaye ii-pixels zibiza kakhulu.

Ingaba iinxuwa ezifanayo ziqhuba into eyahlukileyo?

Iinjini zifana - iilayibrari ezifanayo, abasebenzi abafanayo, iziqhoboshi ezifanayo. Okuhlukileyo kumbono odityanisiweyo, kwaye umbono apha uhlala kwipropathi yefomati le ndawo ibizwa emva: i-.webp efana ne-extension ingagcina i-VP8 frame elahlekile, enye engalahlekiyo, okanye udweliso, ngoko ke indlela yokusebenza efanelekileyo igqibwa ngefayili nganye kunokuba yi-extension nganye.

Yintoni eyenza ifayili yam, kwaye ngaba i-akhawunti ifuneka?

Akukho akhawunti, kwaye akukho nto igcinwa: ulayisho lususwa abasebenziyo emva komsebenzi ugqiba, kwaye akukho nto ivavanywa, idweliswe okanye iqulathe isalathisi. Iiakhawunti zikhona kuphela kwimbali kunye nobungakanani beqela.
