Indlela yokuguqula ubungakanani PNG

1 Layisha phezulu i PNG images ofuna ukuyiguqula ubungakanani bayo - sebenze ukusuka kwi-original enkulu onayo kunokuba usebenze kwikopi esele uyincinane.

2 Ngenisa ububanzi obumiselweyo, ubude obumiselweyo okanye iphesenti, kwaye ushiye isitshixo sothelekiso lwezinto ezibonakalayo sisebenza ngaphandle kokuba ufuna ukutsala ngokuzithemba.

3 Sebenzisa ubungakanani kwakhona; ifayile nganye kwiqela lithathwa kwinjongo efanayo kwindlela enye.

4 Layisha ezantsi ifayili eguqulwe kancinane PNG, okanye iseti yonke kunye njengendawo yokugcina enye.

Tshintsha ubungakanani PNG Imibuzo ebuzwa rhoqo

I Tshintsha ubungakanani PNG itshintsha njani iimfuno?

Ngokucacileyo, ii pixels ziphinda zithathwe ngecebo lokucoca i Lanczos kwaye zibhalwe kwakhona ngaphandle kolahleko, ngoko into ekuphela kwayo ongayilahla yinkcukacha engazifani nge pixels ezincinci; akukho nto idityaniswe yi-encoder ephezulu. Unika ububanzi obumiselweyo, ubude obumiselweyo okanye iphesenti, kwaye isebenza ukusuka kukuqala kunokuba ukusuka kwikopi eyenziwe ukuba ibe mkhulu ngaphambili.

Ndingagcina njani uthelekiso lwezinto ezibonakalayo, okanye ndivumele ubungakanani obuchanekileyo?

Zonke. Tshixa uthelekiso kwaye ubungakanani obunye buvela kwelinye, ekufuneka uyenze rhoqo. Tshixa kwaye ufumane amanani abhaliweyo, ngexabiso lokutsala - esebenzayo kwi slot emiselweyo, engalunganga kwi mifanekiso.

Ingaba ifomati yombhalo inegalelo kwiziphumo zotshintsho lobungakanani?

Iyenza. I-PNG yi-DEFLATE engalahlekiyo enesiqhagamshelanisi esipheleleyo se-8-bit alfa kunye nobunzulu obukhethwayo be-16-bit, ngoko ke ayizukuhlanganiswa kwi-re-save kodwa ifumana uninzi kwizinto eziqulethe imifanekiso. Oku kugqiba ukuba uxinzelelo lwefayile luyingxaki ye pixels kuphela okanye ingxaki yokubuyisela ukukhowuda.

Yintoni impazamo eqhelekileyo xa utshintsha ubungakanani be PNG images?

Ukunyuka. Ukunyusa akukwazi ukuvelisa inkcukacha ezingazange zithathelwe, ngoko ke impumelelo yifomathi ecocekileyo yokuqala kubungakanani obukhulu. Soloko uguqula ubungakanani ezantsi ukusuka kumcebo omkhulu onawo, uguqula ubungakanani kabini endaweni yemizuzu.

Yintoni imilinganiselo kufuneka ndiyibeke njengenjongo?

Uthelekiso lwe slot iya kuhlala kuyo. Ububanzi obupheleleyo web hero akazange afune ngaphezulu kwe 1920 pixels ububanzi, imixholo umfanekiso 1200, ithumbnail 400, kwaye ukuphindaphinda la manani iquka high- DPI ikhusi. Nantoni na ngaphezulu kwee bytes akukho mntu ubona.

Yintoni endinokuyilayisha kwi Tshintsha ubungakanani PNG?

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 Tshintsha ubungakanani PNG?

Ewe: ii-akhawunti ezikhululekileyo ziqhubekeka imifanekiso ukuya kwi-5 MB nganye; amacebo angenangxaki abetha loo mphezulu kuqala kunemifanekiso, kuba akukho nto ifunyenwe. 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 Tshintsha ubungakanani PNG iya kunyusa ubunjani be PNG images yam?

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

Ndingaqhuba i Tshintsha ubungakanani PNG kwi PNG images ezininzi ngaxeshanye?
