Indlela yokujika PNG

1 Layisha phezulu i PNG images ofuna ukuyibona.

2 Khetha umgca ongagqibekanga - othe tyaba unika umfanekiso we- mirror, othe nkqo ubonisa umbono ojikelezayo phantsi.

3 Sebenzisa ujikelezo, emva koko khangela naliphi na inqaku, ilogo okanye inani kwimboniselo yangaphambili, kuba ezi zibonisa ngaphaya kunye nezinye zonke izinto.

4 Layisha ezantsi ifayili ejikelezayo PNG.

Jikelezisa PNG Imibuzo ebuzwa rhoqo

I-Jikelezisa PNG ibonisa njani ifayili?

Ngokucacileyo, iincopho okanye iithayile zitshintshwa indawo kwaye zibhalwe ezantsi, ngoko ke isiphumo sifana nesiphumo ngaphandle kotshintsho. Ukhetha umgca ohamba phambili - othe tyaba uvelisa umfanekiso we mirror, othe nkqo uvelisa umbono ojikelezayo - kwaye ifayile yonke iguqulwa kuyo.

Yintoni utshintsho phakathi kokujika nokujika?

Ujikelezo lubuyisela umva imixholo ejikeleze umgca ojikelezayo kwaye luvelisa umfanekiso we mirror; ujikelezo lubuyisela ngaphandle kokubuyisela umva nantoni na. Umbhalo unika: ufunda ezantsi emva kojikelezo kwaye uhlala ufundeka emva kojikelezo.

Ingaba ifomati yombhalo ibalulekile xa ijikelezisa?

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 ngaba i-mirror ingakwenziwa ngokubhalela kwakhona ifayile okanye ifuna ukuyikhupha kwikhowudi kuqala.

Ewe — akukho mqolo womgangatho ophosakeleyo — i-PNG ijikeleza-ihamba ngokuchanekileyo, ngoko into ekuphela kwayo eyenza utshintsho ibiza ubungakanani befayili. Kufuneka ulinde ixesha ngaphambi kokuba ujikelezise into engayi kuyenza kwakhona ngokulula.

Ndiza kuzama nini ukujika imifanekiso?

Ukulungisa uvavanyo okanye ukuthatha i-webcam eyaphuma ifana, yenza isibini esilinganayo sezinto eziphilayo, okanye uthelekiso lokuhamba kwento ejonge ubeko. Ukuba imixholo iqulethe umbhalo, ilogos okanye amanani, khangela isiphumo - ezifana nazo.

Ndingayijika iifayili ezininzi ngaxeshanye?

Ewe. I-axis efanayo isetyenziswe kwifayile nganye kwiqela, eyenza ukuba ulungise isiqulathi seefayili esipheleleyo semifanekiso ejikelezayo ethathwe kwindlela enye endaweni yenye ngexesha.

Yintoni endinokuyilayisha kwi Jikelezisa 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 Jikelezisa 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 Jikelezisa 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 Jikelezisa PNG kwi PNG images ezininzi ngaxeshanye?

Ewe - thumela umyalezo kwi Internet.

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.

Ingaba i Jikelezisa PNG ibiza nantoni na?

No. Jikelezisa PNG isebenza ngokukhululekileyo ngaphandle kwe-akhawunti kwaye idibanisa akukho phawu lwamanzi. Iifayili zisuswa kubasebenzi emva kokuba ulayishe, kwaye akukho nto malunga nomfanekiso igcinwa.
