Dɛn ne PNG a ɛda adi pefee?

By Technical specialist

PNG a ɛda adi yɛ mfonini fael a wɔayɛ afã horow bi sɛ ɛbɛkyerɛ biribiara nni asɛmti no akyi, enti biribiara a wode fael no bɛto so no betumi ada adi afa so. Saa “biribiara nni hɔ” no nyɛ paint fitaa na ɛnyɛ checker nsusuwso a ɛyɛ fitaa. Ɛyɛ transparency data, a wɔtaa ka ho asɛm sɛ alpha.

Sɛ wode nneɛma a wɔatwa, avatar, sticker, slide, anaa nneɛma a wɔabom ayɛ ntɛmntɛm yɛ adwuma a, eyi ho hia sen sɛnea ɛte. Nnipa pii ka sɛ “Mehia sɛ woyi akyi no fi hɔ,” nanso nea wohia ankasa ne fael a ebetumi atra nhyehyɛe foforo bi atifi a ɛho tew a ɛntwe akyi dedaw no nkɔ.

Adwene a ɛnyɛ den no

Fa no sɛ mfonini a wɔde di dwuma daa no yɛ ahinanan a piksel ahyɛ mu ma. Saa ahinanan no fã biara wɔ kɔla a wotumi hu. PNG a ɛda adi pefee sesa saa mmara no:

• asɛmti no sie piksel a wotumi hu
• akyigyina a woayi afi hɔ no bɛyɛ beae a ɛda adi pefee
• krataa foforo, kɔla, anaa mfonini foforo betumi apue wɔ n’akyi akyiri yi

Ɛno nti na PNG a ɛda adi pefee abu so kɛse ma nneɛma ne nnipa a atew ne ho no. Wɔma wutumi yɛ nsakrae bere a wode akɔ amannɔne awie no.

Nea enti a checkerboard preview no wɔ hɔ

Sɛ nea ɛda adi pefee yɛ “biribiara” a, ɛbɛyɛ dɛn na softwea atumi akyerɛ?

Nsɛm ho amanneɛbɔfo ne ahwɛfo dodow no ara de checkerboard nhwɛso di dwuma de gyina hɔ ma mpɔtam a ɛda adi pefee. Checkerboard no nyɛ ɛnyɛ fael no fã. Ɛyɛ preview convention kɛkɛ sɛnea ɛbɛyɛ a w’ani betumi ahu baabi a alpha wɔ.

Eyi yɛ adwene a ɛyɛ basaa a ɛtaa ma wɔn a wɔrefi ase no mu biako:

• “Me export file no na afei mehu squares”
• “Akyi yiyi afiri no de nsusuwso a ɛyɛ fitaa kaa ho”

Mpɛn pii no, ahinanan no yɛ ɔkwan a nea ɔhwɛ no fa so kyerɛ sɛ ɛda adi pefee nkutoo. Fael no ankasa reyɛ ade a ɛteɛ.

Transparent PNG vs akyi fitaa

Mpɛn pii no, nneɛma abien a efi mu ba yi frafra, nanso ɛsono emu biara.

PNG a ɛda adi pefee

• akyi no woyi afiri mu ko alpha
• yɛ adwuma yiye bere a ebia wode asɛmti no bɛto akyigyina ahorow pii so akyiri yi
• a eye sen biara ma compositing, layouts, ne flexible reuse

Fitaa akyi

• akyi da so ara wo ho, fitaa kɛkɛ
• betumi ayɛ mfasoɔ ama gua so, docs, anaase nneɛma a wɔde kɔ amannɔne a ɛnyɛ den
• less flexible se akyiri yi wopɛ asɛmti no wɔ kɔla, gradient, anaa mfonini foforo so a

Wɔn mu biara nyɛ “ɔbenfo kɛse” wɔ biribiara mu. Wodi ɔhaw ahorow ho dwuma. Ɔhaw fi ase bere a obi hwɛ biako kwan na ɔde foforo no kɔ amannɔne wɔ akwanhyia mu no.

Nea enti a PNG ho hia wɔ adwumayɛ nhyehyɛe yi mu

PNG ne mmuaeɛ a mfasoɔ wɔ so ɛfiri sɛ wɔboa no kɛseɛ na wɔte aseɛ kɛseɛ ma nsusuiɛ a ɛda adi pefee. Wubetumi abue JPG, WebP, AVIF, anaa HEIC mfonini sɛ input, ayi akyi no, na wode nea wɔatwa no akɔ amannɔne sɛ PNG.

Ɛno kyerɛ sɛ adwumayɛ ho asɛmmisa no nyɛ:

“So na mfitiase fael no da adi dedaw?”

Ɛyɛ:

“So metumi atew asɛmti no ho na mede nea ebefi mu aba no asie wɔ ɔkwan a ɛbɛma nneɛma a ɛda adi so akora so?”

Wɔ Easy Background Remover fam no, saa mmuae a etwa to no yɛ PNG.

Nea alpha kyerɛ a jargon dump nni mu

Alpha yɛ mfonini data no fã a ɛkyerɛkyerɛ sɛnea ɛsɛ sɛ piksel bi da adi.

• pixel a wotumi hu koraa: asɛmti no kyerɛ koraa
• fully transparent pixel: biribiara nni hɔ a efi saa pixel no mu nka
• fã bi a ɛda adi: nsakrae a ɛyɛ mmerɛw anaa nea ɛda adi fã bi betumi aba

Ɛho nhia sɛ wobɛyɛ mfoniniyɛfo ansa na wode adwene yi adi dwuma. Wɔ asetra ankasa mu no, ɛkyerɛkyerɛ nea enti a anoano a ɛyɛ mmerɛw betumi ayɛ sɛ nea ɛyɛ abɔde bere a nea wɔatwa no ye, ne nea enti a nneɛma a wɔde kɔ amannɔne a ɛnyɛ den no hwɛ yɛ abofono bere a wɔhweree nea ɛda adi pefee anaasɛ wɔansiesie anoano no mu kɛkɛ.

Baabi a PNG ahorow a ɛda adi pefee ho wɔ mfaso

PNG ahorow a ɛda adi pefee no ho wɔ mfaso titiriw bere a ebia ɛho behia sɛ asɛmti koro no ara tu kɔ nsɛm a ɛfa ho ntam no:

• a woahyehye no ne promo kaad
• profile mfonini ne kuw nkratafa
• slide decks ne docs
• labels, stickers, ne print prep a ɛnyɛ den
• a wode kata so ma mfonini nketewa anaase mockups

Ɛnyɛ “PNG yɛ nea ɛyɛ fɛ.” Nea ɛyɛ anigye ne sɛ asɛmti no kɔ so yɛ nea wotumi de di dwuma bio.

Nea PNG a ɛda adi pefee no ankasa nsiesie

PNG a ɛda adi pefee nyɛ adanse a ɛyɛ adwuma ankasa a ɛkyerɛ sɛ nea efi mu ba a ɛho tew.

Wubetumi akɔ so anya:

• a ɛyɛ rough edges
• a aka halos a efiri akyire dedaw no mu
• a eyera ti nhwi nhama
• twa ntwea so wo nsem a nsonsonoee ketewaa mu

Nneɛma a ɛda adi pefee no kora nea wɔatwa no so. Ɛnsiesie baabi a wɔatwa no mmerɛw wɔ n’ankasa mu.

Ɛno nti na edge inspection ho hia no. Fael no format ne cutout quality no bom yɛ adwuma, nanso ɛnyɛ ade koro.

Nhwɛso a mfaso wɔ so

Fa no sɛ kuruwa bi a wɔatwa mfonini wɔ fitaa so. Sɛ woyi akyi no na wode kɔ amannɔne sɛ PNG a ɛda adi a, akyiri yi wubetumi de saa mug no ahyɛ:

• a wode kɔla ayɛ frankaa
• a ɛyɛ gradient ɔbran block
• a ewo gua so tile
• a wode kyerɛkyerɛ mu

Sɛ wode akyi fitaa kɔ amannɔne mmom a, ebia wobetumi de kuruwa no adi dwuma da so ara, nanso ahinanan fitaa anaa mprɛte no to baabi a ɛte sɛ nea ɛyɛ abɔde ano hye. Transparent version no ma wo san de di dwuma pii.

Mfomso a wɔtaa di

Mfomso 1: sɛ yɛfa no sɛ akyi mfonini fitaa a, ɛkyerɛ sɛ ɛda adi pefee

Ɛnyɛ saa. White da so ara yɛ kɔla ho nsɛm. Transparency yɛ backdrop data a wotumi hu a enni hɔ.

Mfomso 2: wosusuw sɛ checkerboard no yɛ fael a wɔde akɔ amannɔne no fã

Mpɛn pii no, ɛyɛ nhyiam a wɔyɛ ansa na wɔadi kan ayɛ ara kwa. Hwɛ fael no wɔ tebea foforo mu ansa na woasi gyinae sɛ biribi anyɛ yiye.

Mfomsoɔ 3: export kɔ format a ɛtɔ alpha

Sɛ wuhia sɛ wɔyɛ nneɛma a ɛda adi pefee a, ɛsɛ sɛ nea etwa to a wode bɛma no kora so. Wɔ saa adwumayɛ nhyehyɛe yi mu no, ɛno kyerɛ PNG.

Mfomso 4: asodi a wɔde to PNG so wɔ ano bɔne ho

Sɛ anoano no hwɛ sɛ enye a, asɛm no taa yɛ mask quality anaasɛ refine a enni hɔ, ɛnyɛ nokwasɛm a ɛyɛ sɛ fael no yɛ PNG.

Pon a ɛyɛ ntɛm

The plain-English takeaway

PNG a ɛda adi pefee yɛ ɔkwan a mfaso wɔ so ara kwa a wobɛfa so akora asɛmti no so bere a woyi akyi mfonini a wotumi hu no fi hɔ, enti wubetumi de saa asɛmti no akɔ baabi foforo a ɛho tew akyiri yi.

Ɛno ne adwene no nyinaa. kasakoa a wɔde di dwuma no yɛ nea obi betumi apaw.

Sɛ wopɛ nsaanodwuma a, kɔ so de Sɛnea wɔyɛ PNG a ɛda adi. Sɛ wopɛ input/output fã a, hwɛ Mfonini ahorow a wɔboa.
