Izinsiza zezithombe

Izinsiza zesithombe zamahhala ezisebenza ebrawuza yakho, hhayi eseva

Iningi lezikhathi awudingi i-Photoshop. Udinga ukulungisa into eyodwa ekucasulayo mayelana nesithombe: asivuli, sikhulu kakhulu ukuthumela nge-imeyili, sinesimo esingalungile, noma sigcinwe ohlotsheni uhlelo olulandelayo olungeke lulufunde. Yileyo sikhala lezi zinsiza ezisigcwalisayo. Yonke into lapha isebenza ngokwendawo isebenzisa i-Canvas API yebrawuza yakho, ngakho isithombe osifakayo sicutshungulwa kudivayisi yakho uqobo futhi asize salayishwa kunoma yikuphi. Akukho i-akhawunti, akukho uphawu lwamanzi, akukho ukulinda emgqeni.

Ake sihambe kuzo izinkinga abantu abahlangabezana nazo ngempela, kanye nokuthi iyiphi insiza exazulula ngayinye.

Isithombe se-iPhone esingavuli ku-Windows

Lokhu kuvela njalo naJalo. Uthatha isithombe nge-iPhone, usithumele nge-AirDrop noma nge-imeyili kukhompyutha ye-Windows, futhi ifayela liphelela nge-.heic esikhundleni se-.jpg. Isikhathi esiningi i-Windows ijika amahlombe ibonise ithumbnail elingenalutho. I-HEIC uhlobo oluhle ngempela — i-Apple iyisebenzisa ngoba icindezela isithombe esisezingeni eliphakeme endaweni ecishe ihhafu yesikhala se-JPEG — kodwa ukusekelwa ngaphandle komhlaba we-Apple kusengaphenya. Isixazululo silula: sidlulise ku-HEIC to JPG uthole i-JPEG evamile evula noma yikuphi, kufaka izibukisi zezithombe ezindala, izinhlelo ze-imeyili, kanye nalelo fomu lokulayisha elamukela kuphela i-JPG ne-PNG.

Amagama ambalwa ngezinhlobo, ngolimi olulula

Awudingi ukukhumbula iphepha lomklamo, kodwa ukwazi ngokusobala ukuthi yiluphi ohlelweni ozosebenzisa ngasinye kunqanda usizi oluningi.

I-JPG (JPEG) yisibambiso sezithombe. Ilahla imininingwane ongeke uyibone kalula ukushintshanisa ngamafayela amancane, okuyilokho ngempela okudingayo ezithombeni zamaholide nezomkhiqizo. Umbhaqo: ayinawo ukubonakala (transparency), futhi ukulondoloza i-JPG efanayo izikhathi eziningi kuyiguqula kancane kancane ibe mbi.

I-PNG igcina i-pixel ngayinye ngokugcwele futhi isekela ukubonakala, ngakho iyona ekhethiwe amaphawu, izithombe ezitshentshiwe (screenshot), amadayagramu, kanye nanoma yini enemikhawulo ecacile noma umbhalo. Umehluko amafayela amakhulu — isithombe esilondolozwe njenge-PNG singaba mahlanu amakhulu kunohlobo lwe-JPG.

I-WEBP indawo yesimanje ephakathi evela ku-Google. Ngokuvamile inqoba i-JPG ne-PNG ngobukhulu befayela ekhwalithini efanayo futhi isingatha nokubonakala. Cishe ibrawuza yonke yamanje iyakwazi ukuyifunda, okuyenza ibelungile amawebhusayithi — nakuba amanye ohlelweni oludala olusekthophu lungakwazi, yingakho ukuba nesiguquli kubalulekile.

I-BMP, GIF, SVG zivela kancane. I-BMP ayicindezelekile futhi inkulu; iningi liguqula ukusuka kuyo. I-GIF eyeziswidiswidi ezilula. I-SVG umsebenzi we-vector ohlala ubukhali kunoma iyiphi ubukhulu — kuhle kuze kube yilapho okuthile kudinga isithombe se-pixel elijwayelekile, lapho khona i-isiguquli sesithombe siguqula i-SVG yakho ibe i-PNG.

Amafayela amakhulu kakhulu ukuthumela

Abahlinzeki be-imeyili bakhawulela izifaka cishe ku-20-25 MB, izinhlelo zenkulumo ziphindisela ngisho nakuqala, futhi isithombe sefoni singaba mahlanu-njenge-12 MB ngokwaso. Namathisela zintathu ubohleliwe. Insiza yokucindezela isithombe e-image compressor incipha ifayela ngaphandle kokushintsha izilinganiso zayo, futhi ezithonjeni eziningi umphumela ubukeka ufanana neliso.

Nasi iqiniso mayelana nokuthi ukucindezela kusebenza kanjani: kuwushintshaniswano. Isikhwelisi se-JPEG noma se-WEBP silula izingxenye zesithombe ongeke uzibone kalula — ukuguquka okucashile esibhakabhakeni, imininingwane ecashile emithunzini — futhi ngokuya sikwenza kakhulu, ifayela liya lincipha kanti ukulahleka kuya kubonakala. Ngezilungiselelo ezimnene uzosika ubukhulu ngehhafu noma ngaphezulu ngaphandle koshintsho olubonakalayo. Sikucindezele kakhulu bese ubona amabala aphaquzelayo kanye nemikhawulo enokungacaci. Indawo enhle inikwa isithombe, ngakho kuhlomulisa ukubuka ukubukwa kwangaphambili ngaphambi kokuzibophezela. Ukushintshwa kobukhulu kuyasiza nakho: uma udinga isithombe ngobubanzi be-1200 pixel kuphela, akukho isizathu sokuthumela okwangempela okwe-4000 pixel. I-insiza yokushintsha ubukhulu iyalungisa lokho, futhi ngokuvamile iyanciphisa ifayela ngamandla kunokucindezela kodwa.

Wakha iwebhusayithi? Uzodinga i-favicon

Uphawu oluncane ethebhini yebrawuza lubizwa nge-favicon, futhi ababrawuza ngokwesiko balindele njengefayela le-.ico. Uma unophawu lwesikwele njenge-PNG, i-PNG to ICO iyicindezela ibe uphawu olufanele ngobukhulu obujwayelekile obuphekwe ngaphakathi, ukuze luhlale lubukhali noma ibrawuza ibonisa lona lulincane ethebhini noma lulukhulu ku-bookmarks bar. Qala ngesithombe esiyisikwele esiyi-256×256 pixels ubuncane futhi ukubonakala kuhamba kahle ngaphandle kwezingqinamba.

Kungani okwendawo kubaluleke kangaka

Iziguquli eziningi ku-inthanethi zenza umsebenzi emaseveni azo, okusho ukuthi ifayela lakho lisuka kudivayisi yakho, lihlale kwenye ihadiwe, futhi uthembela enqubomgomweni yayo yokugcina. Kubukisi kulungile. Kufakela le-passport, isivumelwano, isithombe sokwelapha, noma noma yini enobuso, kufanele ucabange kabili. Ngoba lezi zinsiza zisebenzisa i-Canvas API ngqo ebrawuza yakho, isithombe asisuki nakuphi — ungaphonsa nekhebula lenethiwekhi phakathi nesikhathi soguqulo kanti sizoqedela. Lokho kushesha nakho: akukho ukulayisha, akukho ukulanda, akukho umkhawulo wobukhulu obethwe eseva.
