Indlela yokuguqula ubukhulu BMP

1 Layisha phezulu i-BMP images oyifunayo ukuguqulwa isilinganiso - sebenze kusuka ku-original enkulu onayo endaweni yokukopela okwenze wancipha kabili.

2 Ngenisa ububanzi obufunayo, ubude obufunayo noma iphesenti, futhi ushiye ukuvala isilinganiso sesimo esivulekile ngaphandle kokuthi ufuna ukudlulisa ngokuzimela.

3 Sebenzisa ukuguqula ubukhulu; yonke ihele eqenjini lithathwa kulapho lifuna khona ngesinqumo esifanayo.

4 Layisha phezulu ihele eliguqulwe isilinganisi BMP, noma ihele lonke lihlanganise njengehele elilodwa.

Buyisela ubukhulu BMP Imibuzo Evame Ukubuzwa

Indlela i Buyisela ubukhulu BMP eshintsha ngayo izilinganiso?

Ngokucacile, ama-pixels aphinde athathwe nge-Lancos filter futhi abhalwe emuva ngaphandle kokulahleka, ngakho-ke into eyodwa olahlekelwa yiyo yimingwane engeke ifike kuma-pixels ambalwa; akukho okushiwo yi-encoder ephezulu. Unikeza isinqumo sobubanzi, isisinqumo sobude noma isiphesenti, futhi isebenza kusuka ku-original ngaphezu kokukopiwe okuncane ngaphambili.

Ingabe ngigcina isilinganiso sesimo, noma ngicindezele izilinganiso ezifanele?

Zonke ezimbili. Khusela isilinganiso futhi ubukhulu olunye luvela kwezinye, okuwukuthi ofunayo cishe njalo. Khusela futhi uthola inani elifanele obhalelayo, ngezindleko zokuziqinisa — okudingekayo ku-slot eqinile, okungalungile ku-photo.

Ingabe ifomethi yomsuka ithinta imiphumela yokuguqula ubukhulu?

Isebenza. I-BMP iyisici esibalulekile esingenakucindezelwa esingenakucindezelwa se-RGB nama-rowes anesihloko esincane, ngakho-ke ayilahleki futhi ikhulu — 10-20x ubukhulu besithombe esifanayo njenge-PNG. Lokhu kusho ukuthi ngabe ukuncipha kwehele kuyisimangalo se-pixels noma simangalo sokuphinde ubhale kabusha.

Ingabe kukhona okuthile okukhethekile ku BMP okufanele ngibhekane nalo?

Yebo — ngoba akukho okucindezelwe, i-BMP ishesha ukufunda nokuhlela kodwa iphoqa uku-upload, futhi ayihambisani ne-metadata yokulondoloza. Kufanele ukuhlola ngaphambi kokuguqula ubukhulu behele, ngeke ukwazi ukulivuselela.

Yini iphutha elivame kakhulu uma ushintsha ubukhulu BMP images?

Ukuphakama. Ukukhululwa akukwazi ukusungula imingwane engakaze ithathwe, ngakho-ke imiphumela iyisiguqulo esilula sokuqala esingubukhulu obukhulu. Qaphela ushintsho lwesayizi ngezansi kusuka kumthombo omkhulu onawo, futhi ushintshe isayizi kabili ngaphezu kokwehla.

Yini izilinganiso okufanele ngizibeke njengenjongo?

Uzofana nesiteshi esizohlala kuso. Umdlali wewebhu ogcwele ububanzi angeke afune okungaphezu kuka-1920 pixels ububanzi, isithombe sezinto ezingaphakathi 1200, ithumbnail 400, futhi ukudubula lezi nombolo kuzoba ne-high-DPI screens. Noma yini engaphezu kwalokhu yi-bytes akukho muntu obona.

Yini engikwazi ukuyifaka ku Buyisela ubukhulu BMP?

PNG, BMP ne TIFF yifomethi ye-raster engalahlekelwa yisimo esiphatha ngokuqondile, futhi ama-lossesy sources (JPG, WebP, GIF) asebenza futhi uma ufuna ukuba kulowo mhlangano. I-TIFF enekhasi elilodwa noma eliningi itholakale futhi iphathwa ikhasi ngekhasi.

Ingabe kunesilinganiselo sobukhulu behele ku Buyisela ubukhulu BMP?

Yebo: ama-akhawunti amahhala asebenza izithombe kuze kube yi-5 MB ngayinye; ama-sources angeke alahlekelwa yisimo esiphezulu kuqala kunama-photographs, ngoba akukho okuthunyelwe okwamanje. Uma ungaphezu kwayo, ukushintshana ku-PNG kuqala kuvame ukunethezeka ngokwayo — i-BMP ivame ukube yiminyaka eyisithupha kuya kweziyishumi ubukhulu besithombe esifanayo njenge-PNG.

Ingabe Buyisela ubukhulu BMP izonciphisa ukhwalithi ye BMP images yami?

Akukho. Umsuka ongenalutho ujikeleza-uhambe nge-bit-efanele, ngakho-ke uma ungacela ngokucacile ifomu lokukhishwa elinalutho ama-pixels abuyela emuva yi-pixels asuka ngaphakathi. Lokhu kuyisizathu esiphelele sokuqhubeka nokusebenza kulolu mndeni ngenkathi uqhubeka nokulungisa.

Ingabe ngizosebenzisa Buyisela ubukhulu BMP ku BMP images amaningi ngasikhathi sinye?

Yebo — thumela iset futhi iqhubekele phambili ngokufanayo ngaphansi kweset eyodwa yezilungiselelo. Amafayela angekho emthethweni akhulu, ngakho-ke iqembu elikhulu liboshwe yijubane lakho lokulayisha ngaphezu kokuqhubekela phambili.

Ingabe isixhumi se-alpha sizohlala?

Yebo. I-PNG ne-TIFF zifaka isixhumi esigcwele se-8-bit alfa futhi zigcinwa kuze kube yilapho. Zihlanganiswa kuphela uma ubeka inhloso yohlelo olungena-alpha, lapho ama-pixels acacile ehlanganisana emhlophe.

Ingabe Buyisela ubukhulu BMP ibiza noma yini?

No. Buyisela ubukhulu BMP isebenza ngokukhululekile ngaphandle kwe-akhawunti futhi ayisebenzisi i-watermark. Amafayela asuswa ku-workers ngemuva kokulanda, futhi akukho okuphathelene nesithombe esigcinwe.
