JPG kumashure kugumira: izvo iyo fomati isingakwanise kuchengeta
JPG haigone kuchengeta kumashure kwakajeka. Pixel yega yega muJPG inofanirwa kugadzirisa kune inooneka ruvara, saka cutout yakachengetwa seJPG inotsikiswa nechena, dema, kana rumwe ruvara rwakasarudzwa. Kana iwe uchida nzvimbo yakatenderedza chinyorwa kuti irambe isina chinhu, tumira kunze PNG panzvimbo.
Izvi zvinogumira hazviiti kuti JPG ive yakaipa sosi foto. Zvinongoreva kuti JPG uye kubuda pachena kune mabasa akasiyana.
Zvinoreva kuti “kutadza kuchengeta pachena”
A cutout ine marudzi maviri eruzivo:
- ruvara runoonekwa rwechinyorwa;
- mapikisi ega ega anofanirwa kuoneka sei, kusanganisira isina chinhu uye chikamu chakajeka kumucheto pixels.
Chikamu chechipiri chinowanzonzi alpha. JPG haina nzvimbo yekuichengeta.
Kana software ikashandura kuchekwa kwakajeka kuita JPG, inofanirwa kusarudza kuti ndeupi ruvara runooneka runotsiva pixel yega yega isina chinhu. Mhedzisiro inova rectangle yakakwana zvakare. Kazhinji iyo inotsiva ichena, asi inogona kunge iri nhema kana chero yakasarudzwa kuzadza.
Hapana chakaipa nefaira. Mashoko akajeka akabviswa nekuti mafomati ekwaaienda haakwanise kuatakura.
Kuti uwane nhanganyaya yealpha-ChiRungu chakajeka, ona What is a transparent PNG?.
JPG inogona kuramba iri yekuisa
Mazhinji mapikicha ekhamera neefoni mifananidzo yakajairwa ine rectangular. Vanosvika nekamuri, mudhuri, mugwagwa, kana tafura yetafura yatooneka kuseri kwechidzidzo. Izvi zvinoita kuti JPG ive yakajairika yekubvisa kumashure.
Iyo inobatsira yekushanda ndeye:
- vhura iyo JPG sosi;
- kusiyanisa nyaya;
- ongorora nekunatsa kumucheto;
- kutumira kunze mhedzisiro itsva sePNG.
Kunobva uye kubuda hazvidi kushandisa chimiro chakafanana. Shandura mufananidzo weJPG kuita PNG inooneka anofamba nebasa iroro zvakananga.
Nei chena kumashure kuchigona kurasisa
Kucheka pamuchena kunogona kutaridzika kujeka kana ichionekwa pane jena peji. Ifambise pane yakasviba siraidhi uye rectangular chena ndiro inova pachena.
Shandisa iyi bvunzo yekukurumidza:
- isa mufananidzo pamusoro peruvara rwakajeka rusina-chena;
- tarisa kumativi mana ose;
- tarisa maburi akapoteredza maoko, zvibato, uye bvudzi.
Kana iyo bvunzo ruvara isingaratidzi kuburikidza nenzvimbo idzodzo, iyo faira inopepetwa. A .jpg zita refaira rinotsigira chikonzero nei. A .png zita refaira rinogona kutsigira kujeka, kunyangwe iyo PNG inogona kunge ichiri kutumirwa kunze nemaune nekuzadza kwakagadziriswa.
Muchena iruvara. Kujeka ndiko kusavapo kwemapikisi ekumashure anooneka.
Mipendero yakapfava inoratidza chimwe chinogumira
Machekwa akanaka haagare aine muganhu wakaoma. Bvudzi, mvere, jira, mimvuri, uye anti-aliased curves zvinogona kuve nechikamu chinooneka kumucheto pixels. Alpha inobvumira iwo mapixels kusanganiswa neyakajeka kumashure.
Kana mupendero wakajeka ukaiswa muJPG, mupendero unosanganiswa nerumwe ruvara rwakatemwa. Isa iyo JPG pane rumwe ruvara uye unogona kuona:
- mufananidzo wakajeka;
- mupendero wakasviba;
- mabhokisi emakona akatenderedza ruzivo rwakanaka;
- matte yakasara kubva pakuzadza kwepakutanga.
Ichi ndicho chikonzero kungobvisa rectangle chena kubva kuJPG gare gare hakuwanzo kudzoreredza yepakutanga cutout. Mapikisheni ekuchinja akatosanganiswa nechena.
Kudzokororwa kweJPG kuchengetedza kunogona kuderedza mhando
JPG inoshandisa kurasikirwa kwekumanikidza. Yakagadzirirwa kuita kuti mifananidzo yemifananidzo iite diki nekurerutsa zvinoonekwa. Imwe neimwe yekuwedzera yekuchengetedza inogona kuunza kurira kwakawanda, kuvharika, kana kuzora, kunyanya kutenderedza mipendero yakapinza.
Izvo zvigadzirwa zvine basa zvakatenderedza muganhu wekuchekwa nekuti mupendero ndipo chaipo panodiwa ruzivo rwakachena. Yakanyanya kudzvanywa sosi inogona kuratidza:
- fuzzy contours;
- zvidhinha zvidiki zvemavara padhuze neratidziro;
- tambo dzakarasika kana zvikamu zvitete;
- ruzha rwemavara runofanana nekumashure ruzivo.
Kuendesa kunze kuPNG kunodzivirira imwe kurasikirwa JPG nhanho mushure mekucheka. Iyo haigone kudzoreredza ruzivo rwakatoshaikwa kubva kunobva, asi inodzivirira kuwedzera JPG compression kune yakajeka mhedzisiro.
Kana JPG ichiri iyo chaiyo yekupedzisira faira
JPG inogona kuve inonzwisisika yekutumira fomati kana zvese izvi zviri zvechokwadi:
- iyo yekupedzisira kumashure inogadziriswa nemaune;
- pachena hazvidiwi;
- mufananidzo wacho unonyanya kutorwa mifananidzo;
- iyo yekuenda inobvuma kana inofarira JPG;
- diki yekutakura saizi inonyanya kukosha pane ramangwana rekuchinja kumashure.
Semuyenzaniso, banner rakapedzwa rine mufananidzo wakazara kumashure rinogona kusabatsirika kubva kune alpha. Iyo yakagadziriswa chena-kumashure catalogue foto inogona zvakare kuendeswa seJPG kana iyo yekugamuchira yakatarwa ichida.
Chinhu chakakosha chinangwa. Rongedza tenzi akajeka pane inodiwa ruvara, wobva wagadzira iyo JPG yekuendesa kopi. Usarase tenzi kunze kwekunge uine chokwadi chekuti nyaya yacho haizomboda imwe nhoroondo.
Tafura yesarudzo inoshanda

Kuti uwane kuenzanisa kwakakura kwemafomati emazuva ano ekucheka, verenga PNG vs WebP vs AVIF yekucheka.
Zvakajairwa kudzoreredza kukanganisa
Kupa zita rekuwedzera
Kushandura image.jpg kuita image.png hakutenderi faira kana kudzoreredza alpha. Tumira kunze kana kushandura kuburikidza nesoftware inonyora PNG data.
Kudzima chena kubva kuJPG yakatsetseka
Izvi zvinogona kushandira magiraidhi akareruka akaomarara, asi kazhinji zvinokuvadza zvikamu zvichena zvechinyorwa uye zvinosiya kucheneruka kusvibiswa. Kudzokera kuna tenzi akajeka kwakachengeteka.
Kutumira preview pachinzvimbo chekutumira kunze
Screenshot inobata iyo yekutarisa yese, kusanganisira chero inooneka yekutarisa. Shandisa mupepeti wekutumira kunze.
Kufunga kuti PNG yese iri pachena
PNG inogona kutakura alpha, asi inogonawo kunge iine yakazara opaque kumashure. Zviratidze pamusoro peruvara rwakasiyana.
Iyo yakachengeteka mafambiro ekushanda
Shandisa JPG pane zvainoita nemazvo: zvakajairika mafoto ekuisa uye compact yakagadziriswa-kumashure kuburitsa. Shandisa PNG apo mhedzisiro inofanirwa kuchengetedza pachena.
Chengetedza yakachena PNG tenzi mushure mekubviswa kumashure. Kubva kuna tenzi iyeye, gadzira JPG chena, JPG yeruvara, kana imwe kopi yekuenda painodiwa. Odha iyi inochengetedza sarudzo uye inodzivirira kuyedza kugadzirisa zvakare pachena mushure mekunge yapepetwa.
