Alpha chiteshi chakatsanangurwa muChirungu chakajeka
Alpha chiteshi chikamu chemufananidzo chinochengeta **kuti pixel yega yega inofanira kuoneka sei **. Nzira dzemavara dzinotsanangura tsvuku, girini, uye bhuruu. Alpha inotsanangura kujeka.
Kana iwe ukabvisa kumashure uye kutumira iyo yakajeka PNG, hausi kungodzima ruvara. Uri kunyora alpha value dzinoti: chengeta iyi pixel, dzima mupendero uyu, kana kuti ita kuti nzvimbo iyi isaonekwe zvachose.
Ndosaka machekwa akajeka achigona kutaridzika sechisikigo kana mipendero yakapfava ichibatwa zvakanaka - uye nei kutengeswa kunze kwenyika kuchitaridzika kunge kusirizvo kunyangwe iyo nyaya pachayo yakapinza.
Iyo iri nyore modhi
Papixel yega yega, alpha inopindura mubvunzo mumwechete:
- yakazara opaque: chinyorwa chinoratidza zvizere
- zvakajeka zvizere: hapana kubva kune iyo pixel inosara
- zvishoma zvakajeka: iyo pixel inosanganiswa nechero inogara kumashure kwayo
Kujeka kwakasarudzika ndicho chikonzero chinoita kuti bvudzi, mvere, uye zvinyoro zvinyoro zvitaridzike zvinotendeseka pane kucheka nechigero.
Nei izvi zvakakosha pakubvisa kumashure
Kubvisa kumashure hakusi “kudzima kumashure.” Mhedzisiro yakanaka inodawo muganhu unozvibata nemazvo kana mufananidzo ukaiswa kune imwe nzvimbo.
Alpha ndiyo inoita kuti mhedzisiro iyi igoneke:
- nyaya inoyangarara pamusoro peruvara rutsva
- mipendero yakapfava inosanganiswa pane kutarisa yakadhindwa
- Checkerboard previews inogona kuratidza matunhu asina chinhu
Pasina alpha, “yakabviswa kumashure” kazhinji inova ndiro chena kana imwe kuzadza kwakasimba.
Mipendero yakapfava vs yakaoma mipendero
Mipendero yakaoma kazhinji sarudzo dzakajeka-kana-pachena. Mipendero yakapfava inoshandisa musanganiswa.
Iko kusanganiswa kunobatsira kune:
- tambo dzebvudzi
- fur
- semi-pachena mapurasitiki
- inofamba-yakasviba contours
Ndimowo panoonekwa dambudziko. Kana alpha yakangoerekana yanyanya, musoro wacho unotaridzika wakatemwa. Kana alpha yakashata, iwe unowana fringe uye halo.
Izvo alpha isiri
Alpha haisi:
- chena kumashure
- iyo checkerboard pattern pachayo
- chivimbiso chemhando yakakwana yemucheto
Checkerboard inongova gungano rekuona. Muchena uchiri ruvara. Alpha i data yekuonekwa.
Muenzaniso unoshanda
Fungidzira chigadzirwa chakachekwa chakaiswa pane rima banner:
- yakanaka alpha: chinyorwa chinogara zvakachena pasina rimu rakachenuruka
- isina kusimba alpha: chena isina kupera kana mupendero weruvara unoramba wakatenderedza contour
Mupendero wacho unowanzo kusara hunhu, kwete zvisinganzwisisike “PNG bug.”
Izvi zvinobatana sei ne Easy Background Remover
Muchirongwa ichi:
- Vhura mufananidzo unotsigirwa
- Bvisa kumashure munharaunda
- Natsa mipendero kana zvichidiwa
- Export PNG kuitira kuti pachena (alpha) zvichengetedzwe
Iwe haufanire kubata alpha chiteshi nemaoko senge mune yakazara graphics suite. Iwe unofanirwa kunzwisisa kuti nei kutumira kunze fomati uye edge yekuchenesa nyaya.
Kukanganisa kwakajairika
Chikanganiso chekutanga: kubata alpha sejagoni sarudzo
Kana iwe uchida kushandiswa zvakare mukati memashure, alpha ndiyo pfungwa yese.
Chikanganiso chechipiri: kuvhiringa mupendero wakapfava nekusara kumashure
Kumwe kupfava kwakanaka. Kuoneka kwekare-kumashure ruvara hausi.
Chikanganiso chechitatu: chengetedza zvakare kuita chimiro chinodonhedza pachena
Kana alpha rarasika, iyo cutout inomira kuchinjika.
Chikanganiso chechina: kupa mhosva pfungwa pachinzvimbo chemupendero
Iro faira rakajeka rinogona kuramba richiratidzika kunge rakashata kana mask yakashata.
