Chii chiri pachena PNG?
PNG yakajeka ifaira remufananidzo apo mamwe mativi anoitirwa kuratidza ** hapana chiri kuseri kwechinyorwa **, saka chero chaunoisa faira pamusoro chinogona kuratidza kuburikidza. Izvo “hapana” haisi pendi chena uye kwete grey checker pattern. Iri data rakajeka, rinowanzotsanangurwa se ** alpha **.
Kana iwe ukashanda nekucheka kwechigadzirwa, maavatars, zvimiti, masiraidhi, kana macomposites anokurumidza, izvi zvinonyanya kukosha kupfuura zvazvinonzwika. Vanhu vazhinji vanoti “Ini ndinoda kuti kumashure kubviswe,” asi chavanoda chaizvo ifaira rinogona kugara zvakachena pamusoro peimwe marongerwo pasina kukwevera kumashure kumashure.
Pfungwa iri nyore
Funga nezvemufananidzo wenguva dzose serectangle izere nemapikisi. Chikamu chimwe nechimwe cherectangle icho chine ruvara rwunooneka. PNG yakajeka inoshandura mutemo iwoyo:
- chinyorwa chinochengeta mapixel anooneka
- iyo yakabviswa kumashure inova nzvimbo yakajeka
- rimwe gwaro, ruvara, kana mufananidzo unogona kuoneka kuseri kwaro gare gare
Ndokusaka maPNG akajeka akajairika kune zvinhu zvakasarudzika uye vanhu. Vanokupa kushanduka mushure mekutengesa kunze.
Nei cheki yekutarisa iripo
Kana pachena “pasina,” software ingazviratidze sei?
Vazhinji vapepeti nevaoni vanoshandisa chekibhodhi pateni kumiririra matunhu akajeka. Iyo checkerboard haisi ** haisi chikamu chefaira **. Ingori gungano rekuona kuitira kuti ziso rako rizive kuti alpha iripo.
Iyi ndiyo imwe yeanowanzo tanga kuvhiringidzika:
- “Ndakatumira kunze faira uye ikozvino ndaona masikweya”
- “Iyo yekubvisa kumashure yakawedzera grey pateni”
Kazhinji masikweya ndiyo nzira yemuoni yekuratidza pachena. Iyo faira pachayo iri kuita chinhu chaicho.
Transparent PNG vs chena kumashure
Izvi zviviri zvinoguma zvinowanzosanganiswa, asi zvakasiyana.
Transparent PNG
-kumashure kunobviswa kune alpha
- inoshanda nemazvo kana iwe uchizoisa chidzidzo pane akawanda akasiyana mamashure gare gare
- yakanakira kuumba, marongero, uye inochinjika kushandiswa zvakare
White background
- kumashure kuchiripo, kuchena chete
- inogona kubatsira kumisika, zvinyorwa, kana nyore kutumira kunze
- isingachinjiki kana iwe uchizoda chidzidzo pamusoro peruvara, gradient, kana mumwe mufananidzo
Hapana kana mumwe “akanyanya hunyanzvi” mune zvese zviitiko. Vanogadzirisa matambudziko akasiyana. Dambudziko rinotanga kana mumwe munhu achitarisira imwe uye netsaona otumira imwe kunze.
Nei PNG ichikosha mukufambiswa kwebasa uku
PNG ndiyo mhinduro inoshanda nekuti inotsigirwa zvakanyanya uye inonzwisiswa zvakanyanya kune inobuda pachena. Unogona kuvhura mufananidzo weJPG, WebP, AVIF, kana HEIC sekuisa, kubvisa kumashure, uye kutumira kunze kwekucheka sePNG.
Izvi zvinoreva kuti mubvunzo wekufamba kwebasa hausi:
“Faira rekutanga rakanga ratove pachena here?”
Ndizvo:
“Ndinogona here kusiyanisa nyaya yacho ndochengeta mhedzisiro mufomati inochengetedza pachena?”
Kune Easy Background Remover, mhinduro yekupedzisira iPNG.
Zvinorehwa nealpha pasina kurasirwa kwejagoni
Alpha chikamu che data yemufananidzo inotsanangura kuti pixel inofanira kuoneka sei.
- pixel inooneka zvizere: chinyorwa chinoratidza zvizere
- pixel yakajeka: hapana kubva kune iyo pixel inosara
- kujeka zvishoma: nyoro kana semi-pachena shanduko inogona kuvapo
Iwe haufanire kuve mainjiniya emifananidzo kuti ushandise iyi pfungwa. Muhupenyu chaihwo, inongotsanangura kuti nei mipendero yakapfava ichigona kutaridzika seyakasikwa kana iyo cutout yakanaka, uye nei hutsinye kutengeswa kunze kwenyika kuchitaridzika kushata kana kujeka kwakarasika kana mupendero usina kunatswa.
Pane maPNG akajeka anobatsira
Transparent PNGs inonyanya kubatsira kana chidzidzo chimwe chete chingada kufamba pakati pezvimiro:
- zvinyorwa zvechigadzirwa uye makadhi ekusimudzira
- mapikicha emifananidzo uye mapeji echikwata
- slide decks uye zvinyorwa
- mavara, zvimiti, uye nyore kudhinda prep
- kuvharika kwezvigunwe kana mockups
Kukwidza hakusi “PNG yakanaka.” Chikumbiro ndechekuti chinyorwa chinoramba chichishandiswa zvakare.
Izvo zviri pachena PNG haigadzirise yega
PNG yakajeka haisi humbowo humbowo hwemhedzisiro yakachena.
Iwe unogona zvakare kuva:
- mipendero yakaoma
- akasara halos kubva kumashure ekare
- bvudzi rakashaikwa
- cheka makona pazvidzidzo zvakaderera
Kujeka kunochengetedza kucheka. Iyo haigadzirisi isina kusimba yekucheka yega.
Ndosaka kuongororwa kwemupendero kunokosha. Iyo faira fomati uye iyo cutout mhando inoshanda pamwechete, asi hazvisi chinhu chimwe chete.
Muenzaniso unoshanda
Fungidzira muga wakatorwa mufananidzo pamuchena. Kana iwe ukabvisa kumashure uye kutumira kunze sePNG yakajeka, unogona kuzoisa iyo gagi pa:
- mureza wemavara
- gradient gamba block
- tile yepamusika
- siraidhi yemharidzo
Kana iwe ukatumira kunze ine chena kumashure panzvimbo, iyo mug inogona kuramba ichishandiswa, asi chena rectangle kana ndiro inogumira painotaridzika seyakasikwa. Iyo transparent version inokupa iwe kushandiswa zvakare.
Kukanganisa kwakajairika
Mistake 1: kutora chena kumashure zvinoreva kujeka
Hazvidaro. White ichiri ruzivo rwemavara. Transparency ndiko kusavapo kwe data rinooneka rekumashure.
Chikanganiso chechipiri: kufunga kuti chekibhodhi chikamu chefaira rakatumirwa kunze kwenyika
Kazhinji ingori gungano rekuona. Tarisa faira mune imwe mamiriro ezvinhu usati wafunga kuti chimwe chinhu chakaipa.
Chikanganiso chechitatu: kutumira kunze kune chimiro chinodonhedza alpha
Kana iwe uchida pachena, yako yekupedzisira inounzwa inofanirwa kuichengetedza. Mukufamba uku, zvinoreva kuti PNG.
Chikanganiso chechina: kupa PNG mhosva yekuipa mipendero
Kana mupendero uchitaridzika kunge urombo, nyaya yacho inowanzo mask mhando kana kushaikwa kwekunatsa, kwete chokwadi chekuti faira iri PNG.
Tafura inokurumidza
| Need | Better result |
|---|---|
| Shandisazve chinyorwa pane akawanda mabackgrounds | Transparent PNG |
| Chengetedza yakagadziriswa plain backdrop | White or colored background |
| Tsanangura kune waunoshanda naye kuti “hapana kumashure” zvinorevei | “Transparent PNG ine alpha” |
| Ongorora kana cutout yakanyatsoshanda | Checkerboard preview + edge cheki |
The plain-English takeaway
PNG yakajeka ingori nzira inoshanda yekuchengeta chidzidzo uchibvisa iyo inooneka kumashure, saka unogona kuisa iyo chidzidzo zvakachena kumwe kunhu gare gare.
Ndiyo pfungwa yese. Iyo jargon ndeyekusarudza.
