Indlela yokuguqula ubukhulu Image

1 Layisha phezulu i-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 Image, noma ihele lonke lihlanganise njengehele elilodwa.

Buyisela ubukhulu Image Imibuzo Evame Ukubuzwa

Indlela i Buyisela ubukhulu Image eshintsha ngayo izilinganiso?

Ngokucacile, ihele ngalinye liphinde lisampuliwe nge-Lanzos futhi libhalwe emuva ngefomethi yayo, ngakho-ke iqembu elixhunywe liphuma lisize ngokuqhubekayo ngaphandle kokucindezelwa ngefomethi eyodwa ejwayelekile kuqala. 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. lefomethi ifundwa futhi ibhalwe nge-streaming pipeline efanayo njengezinye izinto esizixhasayo. Lokhu kusho ukuthi ngabe ukuncipha kwehele kuyisimangalo se-pixels noma simangalo sokuphinde ubhale kabusha.

Ingabe kukhona okuthile okukhethekile ku Image okufanele ngibhekane nalo?

Yebo — ipayipi lifunda ifomu elisemthethweni kusuka kuhele ophezulu kunesiqephu, ngakho-ke ukuthunyelwa okungekuhle kuqhubeka. Kufanele ukuhlola ngaphambi kokuguqula ubukhulu behele, ngeke ukwazi ukulivuselela.

Yini iphutha elivame kakhulu uma ushintsha ubukhulu 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 ifomu lesithombe i Buyisela ubukhulu Image eyamvumela?

Zonke ezijwayelekile — JPG, JPEG, PNG, WebP, GIF, BMP, TIFF, SVG, ICO, PSD, JFIF ne HEIC. Ungaxhuma amafomethi ngokukhululekileyo ku-batch eyodwa; ihele ngalinye liphawulwa kusuka kusihloko sayo futhi lihamba ku-decoder efanele.

Ingabe kunesilinganiselo sobukhulu behele ku Buyisela ubukhulu Image?

Yebo: ama-akhawunti amahhala asebenza izithombe kuze kube yi-5 MB ngayinye ngaphandle kokubheka ukuthi yisiphi isithombe esiyifomethi okwenzele; ImageMagick, libjpeg-turbo, libpng ne libwebp zenza umsebenzi osemthethweni. Izinga liyihele ngalinye, ngakho-ke iqembu lezithombe ezingu-20 MB lilungile nakuba inani lingaphezulu kakhulu komkhawulo.

Ingabe Buyisela ubukhulu Image izonciphisa ukhwalithi ye images yami?

Lokhu kuxhomekeka kulokho okwenze. Umsuka ongenaphutha (PNG, BMP, TIFF) ujikeleza ngokugcwele; othile olahlekelwayo (JPG, WebP, GIF) usuyimikhiqizo yesikhathi sokwengeza esisodwa futhi uphinde ukhombise uma umsebenzi ucela lokho.

Ingabe ngizosebenzisa Buyisela ubukhulu Image ku images amaningi ngasikhathi sinye?

Yebo, futhi ukuxhuma amafomethi eqenjini kulungile — izilungiselelo zisetshenziswa ngefayela ngalinye nge-decoder efanele ngalinye. Ama-akhawunti amahhala asebenza ngefayela elilodwa ngasikhathi sinye; ukudluliswa kususa lokhu.

Yini ezoba nemetadata ne transparency?

EXIF ne-ICC color profile zithunyelwa lapho ifomethi ethengiswa khona ixhasa khona, futhi i-alpha channel ihlala kuyo yonke ifomethi ethengiswa khona. Ukubunjwa kwamehlo kuhlanganiswa kuphela uma ifomethi ethengiswa khona ayinayo indlela yokuyikhombisa.

Ingabe Buyisela ubukhulu Image ibiza noma yini?

No. Buyisela ubukhulu Image ikhululekile ngaphandle kwe-akhawunti futhi ifaka i-watermark. Ukulayisha kususwa kubasebenzi ngemuva kokuqedwa kwemisebenzi.
