Ubugcisa bePixel kwabaqalayo: imiyalelo yokusetyenziswa

Abaphuhlisi be-Indie bahlala bedibanisa iindima ezininzi ngexesha elinye: umyili womdlalo, umdwelisi wenkqubo, umqambi, umzobi. Kwaye xa kufikwa kwimbonakalo, abantu abaninzi bakhetha ubugcisa be-pixel-ekuqaleni bubonakale bulula. Kodwa ukwenza kakuhle, udinga amava amaninzi kunye nezakhono ezithile. Ndifumene i-tutorial kwabo baye baqala ukuqonda iziseko zolu hlobo: kunye nenkcazo yesofthiwe ekhethekileyo kunye neendlela zokudweba usebenzisa i-sprites ezimbini njengomzekelo.

Imvelaphi

Ubugcisa bePixel luhlobo lobugcisa bedijithali apho utshintsho lwenziwa kwinqanaba le-pixel. Inxulunyaniswa ikakhulu nemizobo yomdlalo wevidiyo ukusuka kuma-80s kunye nama-90s. Emva koko, amagcisa kwakufuneka athathele ingqalelo imida yememori kunye nesisombululo esiphantsi. Kule mihla, ubugcisa be-pixel busathandwa kwimidlalo nanjengesitayile sobugcisa ngokubanzi, ngaphandle kokukwazi ukwenza imizobo eyinyani ye-3D. Ngoba? I-Nostalgia ecaleni, ukwenza umsebenzi opholileyo ngaphakathi kwesakhelo esiluqilima ngumngeni owonwabileyo nonomvuzo.

Umqobo wokungena kubugcisa be-pixel usezantsi xa uthelekisa nobugcisa bemveli kunye nemizobo ye-3D, etsala abaphuhlisi be-indie. Kodwa oko akuthethi ukuba kuya kuba lula gqiba umdlalo ngolu hlobo. Ndibone uninzi lwabaphuhlisi be-indie abane-pixel art metroidvanias kumaqonga okuxhasa ngemali. Babecinga ukuba baza kugqiba yonke into ngonyaka, kodwa eneneni babefuna eminye iminyaka emithandathu.

I-Metal Slug 3 (i-Arcade). SNK, 2000

Ubugcisa bePixel kwinqanaba apho abantu abaninzi bafuna ukuyidala kuthatha ixesha elininzi, kwaye zimbalwa kakhulu izifundo ezimfutshane. Xa usebenza ngemodeli ye-3D, unokuyijikajika, uyikhubaze, uhambise iindawo zayo, ukhuphele oopopayi ukusuka kwenye imodeli ukuya kwenye, njalo njalo. Ubugcisa be-pixel obukwinqanaba eliphezulu phantse buhlala buthatha umzamo omkhulu wokubeka iipikseli ngobuchule kwisakhelo ngasinye.

Ngokubanzi, ndikulumkisile.

Kwaye ngoku kancinci malunga nesitayile sam: ikakhulu ndizoba ubugcisa bepixel kwimidlalo yevidiyo kwaye ndifumane inkuthazo kuyo. Ngokukodwa, ndingumlandeli weFamicom/NES, i-16-bit consoles, kunye nemidlalo ye-arcade yama-90. Ubugcisa be-pixel bemidlalo endiyithandayo yelo xesha bunokuchazwa njengobuqaqambileyo, ukuzithemba kunye nococeko (kodwa awucocekanga kakhulu), kunokuba ucace kwaye uncinci. Esi sisitayile endisebenza kum, kodwa ungasebenzisa ngokulula izimvo kunye nobuchule kwesi sifundo ukwenza izinto ezahlukeneyo ngokupheleleyo. Jonga umsebenzi wamagcisa ahlukeneyo kwaye wenze ubugcisa bepixel obuthandayo!

Isoftware

Izixhobo ezisisiseko zedijithali zobugcisa be-pixel zi-Zoom kunye nePencil yokubeka iipikseli. Uya kufumana kwakhona uMlayini, iMilo, Khetha, Hambisa kunye nePeyinti yeBhakethi iluncedo. Zininzi iisoftware ezisimahla nezihlawulwayo ezineseti yezixhobo ezinjalo. Ndiza kukuxelela ngezona zidumileyo kunye nezo ndizisebenzisa mna.

Peyinta (simahla)

Ukuba unayo Windows, iPaint eyakhelwe kuyo yinkqubo yakudala, kodwa inazo zonke izixhobo zobugcisa beepikseli.

piskele (Isimahla)

Umhleli we-pixel osebenza ngokungalindelekanga osebenza kwibhrawuza. Ungathumela ngaphandle umsebenzi wakho njenge-PNG okanye i-animated GIF. Inketho ebalaseleyo kubaqalayo.

GraphigsGale (Isimahla)

I-GraphicsGale yiyo yodwa umhleli endikhe ndeva ngawo owenzelwe ngokukodwa ubugcisa bee-pixel kwaye uquka izixhobo zoopopayi. Yenziwe yinkampani yaseJapan iHUMBALANCE. Ibisimahla ukusukela ngo-2017 kwaye isathandwa, nangona i-Aseprite isanda. Ngelishwa, isebenza kuphela kwi Windows.

Xabisa ($)

Mhlawumbi oyena mhleli udumileyo okwangoku. Vula Umnikezi, iimpawu ezininzi, inkxaso esebenzayo, iinguqulelo ze Windows, iMac kunye LinuxUkuba uzimisele ngobugcisa be-pixel kwaye awukamfumani umhleli ofanelekileyo, mhlawumbi lo nguye.

Umdlalo weMidlalo Studio 2 ($$+)

I-GameMaker Studio 2 sisixhobo esihle kakhulu se-2D esinomhleli olungileyo we-Sprite. Ukuba ufuna ukwenza ubugcisa be-pixel kwimidlalo yakho, kulula kakhulu ukwenza yonke into kwinkqubo enye. Ngoku ndisebenzisa le software ngelixa ndisebenza Ii-UFOs 50, ingqokelela yemidlalo ye-retro engama-50: Ndidala i-sprites kunye nee-animations kwi-GameMaker, kunye ne-tilesets kwi-Photoshop.

Photoshop ($$$+)

I-Photoshop yi-software ebiza kakhulu, isasazwa ngokubhalisa, kwaye ayilungiselelwe ubugcisa be-pixel. Andikucebisi ukuyithenga ngaphandle kokuba ubandakanyeka ekunikeni imifanekiso kwisisombululo esiphezulu, okanye awudingi ukwenza ubuqhetseba obuntsonkothileyo ngomfanekiso, njengam. Unokwenza i-static sprites kunye ne-pixel art kuyo, kodwa inzima kakhulu xa ithelekiswa nesofthiwe ekhethekileyo (umzekelo, i-GraphicsGale okanye i-Aseprite).

Ikhithi yam yobugcisa be-pixel. Yonke into imnyama, ndiyiqaphele ngoku.

Ithebhulethi yemizobo ($$+)

Ndincoma iipilisi zegraphics kuwo nawuphi na umsebenzi wedijithali womfanekiso ukuphepha i-carpal tunnel syndrome. Kulula kakhulu ukukhusela kunokunyanga. Ngenye imini uya kuva intlungu kwaye iya kwanda kuphela - zinakekele kwasekuqaleni. Kuba ndandizoba ngempuku, ngoku kunzima ukudlala imidlalo efuna ukuba ndicofe izitshixo. Ngoku ndisebenzisa iWacom Intuos Pro S.

Inkxaso yesandla ($)

Ukuba awukwazi ukufumana ithebhulethi, ubuncinane fumana inkxaso yesandla. Endiyithandayo yi-Mueller Green Fitted Wrist Brace. Ezinye zixinene kakhulu okanye aziboneleli ngenkxaso yaneleyo. IiCalipers zinokuodolwa kwi-intanethi ngaphandle kweengxaki.

Iipikseli ezingama-96 × 96

Umlo wokugqibela. Capcom, ngo-1989

Masiqalise! Masiqale nge-96x96 pixel character sprite. Njengomzekelo, ndidwebe i-orc kwaye ndiyibeke kwi-screenshot evela kwi-Final Fight (umfanekiso ongentla) ukuze uqonde isikali. Oku большой I-sprite yemidlalo emininzi ye-retro, ubungakanani beskrini: 384x224 pixels.

Kwi-sprite enkulu kangaka kuya kuba lula ukubonisa ubuchule endifuna ukuthetha ngabo. Unikezelo ngepixel nganye lukwafana kakhulu neendlela zakwantu zobugcisa (njengomzobo okanye ukupeyinta) onokuthi uqhelene nazo. Emva kobuchule bobuchule obusisiseko, siya kuqhubela phambili kwii-sprites ezincinci.

1. Khetha i-palette

I-Pixel yingqikelelo enzulu kakhulu kubugcisa bepixel kunayo nayiphi na enye indawo yedijithali. Ubugcisa bePixel buchazwa yimida yayo, njengemibala. Kubalulekile ukukhetha i-palette efanelekileyo; Kodwa ekuqaleni, ndicebisa ukuba ungacingi malunga neepalethi kwaye ukhethe enye yezinto ezikhoyo (okanye nje imibala embalwa engahleliwe) - unokuyitshintsha ngokulula nakweliphi na inqanaba.

Kwesi sifundo ndiza kusebenzisa i-palette yemibala engama-32 esiyidaleleyo Ii-UFOs 50. Kubugcisa bepixel bahlala bedityaniswa ukusuka kwi-32 okanye kwi-16 imibala. Eyethu yenzelwe ikhonsoli eyintsomi eya kubonakala kwenye indawo phakathi kweFamicom kunye neNjini yePC. Ungayithatha okanye nayiphi na enye - i-tutorial ayixhomekeke kwaphela kwi-palette ekhethiweyo.

2. Ulwandlalo olurhabaxa

Masiqalise ukuzoba sisebenzisa isixhobo sePencil. Masizobe umzobo ngendlela efanayo naleyo senza ngayo ngepeni eqhelekileyo kunye nephepha. Ewe kunjalo, ubugcisa be-pixel kunye nobugcisa bendabuko bugqithe, ngakumbi xa kufikwa kwii-sprites ezinkulu. Uqwalaselo lwam lubonisa ukuba amagcisa obugcisa be-pixel awomeleleyo alungile ekuzobeni ngesandla kunye ngokuphambeneyo. Ngoko ukuphuhlisa izakhono zakho zokuzoba kusoloko luncedo.

3. Ukucaciswa kweecontours

Sicokisa iikhonto: susa iipikseli ezongezelelweyo kwaye unciphise ubukhulu bomgca ngamnye ube ipixel enye. Kodwa yintoni kanye kanye egqalwa njengengafanelekanga? Ukuphendula lo mbuzo kufuneka uqonde imigca ye-pixel kunye nezitenxo.

Izitenxo

Kuya kufuneka ufunde ukuzoba imigca emibini esisiseko kubugcisa be-pixel: ethe tye kwaye egobileyo. Ngepeni kunye nephepha yonke into imalunga nokulawula izihlunu, kodwa sisebenza ngeebhloko ezincinci zombala.

Isitshixo sokuzoba imigca yepixel echanekileyo yijagi. Ezi pixels enye okanye amacandelo amancinci atshabalalisa ukuguda komgca. Njengoko benditshilo ngaphambili, ipixel enye yenza umahluko omkhulu kubugcisa be-pixel, ke ukungalingani kungonakalisa bonke ubuhle. Yiba nomfanekiso uzobe umgca othe tye ephepheni kwaye ngequbuliso umntu ubetha itafile: amaqhuma kubugcisa be-pixel ajongeka njenge-squiggle engacwangciswanga.

imizekelo:

Ngqo

Iigophe

Izitenxo zibonakala kwiigophe xa ubude bamacandelo emigca bunganyuki okanye bunciphe ngokuthe ngcembe.

Akunakwenzeka ukunqanda ngokupheleleyo amaqhuma - yonke imidlalo oyithandayo ye-retro unayo (ngaphandle kokuba, ewe, ubugcisa bepixel bubandakanya kuphela iimilo ezilula). Injongo: Gcina ukungalingani kuncinci ngelixa ubonisa yonke into efunekayo.

4. Faka imibala yokuqala

Faka umbala kumlinganiswa wakho usebenzisa ukugcwalisa okanye esinye isixhobo esifanelekileyo. Iphalethi iya kwenza lula le nxalenye yomsebenzi. Ukuba isofthiwe ayiboneleli ukusetyenziswa kweepalati, unokuyibeka ngokuthe ngqo kumfanekiso, njengomzekelo ongentla, kwaye ukhethe imibala usebenzisa i-eyedropper.

Kwikona esezantsi ekhohlo ndizoba umhlobo wethu, sidibane, yiBhola le. Kuya kwenza kube lula ukuqonda ukuba yintoni kanye kanye eyenzekayo kwinqanaba ngalinye.

5. Ukwenza umbala

Lixesha lokubonisa izithunzi - yongeza nje imibala emnyama kwi-sprite. Oku kuya kwenza umfanekiso ubukeke une-dimensional. Masicinge ukuba sinomthombo omnye wokukhanya obekwe ngasentla kwe-orc ngasekhohlo kwayo. Oku kuthetha ukuba yonke into engaphezulu naphambi komlingiswa wethu iya kukhanya. Yongeza izithunzi ngezantsi ngasekunene.

Ubume kunye nomthamo

Ukuba eli nyathelo lingumceli mngeni kuwe, cinga ngomzobo wakho njengemilo emacala-ntathu kunemigca kunye nombala nje. Imilo ikhona kwindawo ene-dimensional emithathu kwaye ingaba nomthamo, esiyakhayo ngoncedo lwezithunzi. Oku kuya kukunceda ukuba ube nomfanekiso-ngqondweni womlinganiswa ngaphandle kweenkcukacha kwaye ucinge ukuba wenziwe ngodongwe hayi iipikseli. I-Shading ayikona nje ukongeza imibala emitsha, yinkqubo yokwakha imilo. Kumlinganiswa owenziwe kakuhle, iinkcukacha azifihli iimilo ezingaphantsi: ukuba u-squint, uya kubona amaqoqo amakhulu okukhanya kunye nesithunzi.

Anti-aliasing (anti-aliasing)

Ngalo lonke ixesha ndisebenzisa umbala omtsha, ndisebenzisa i-anti-aliasing (AA). Inceda ukugudisa iipixels ngokongeza imibala ephakathi kwiikona apho amacandelo amabini adibana khona:

Iiphikseli ezingwevu zithambisa "ikhefu" emgceni. Ukuba ixesha elide icandelo lomgca, liya lide icandelo le-AA.

Yile nto i-AA ibonakala ngayo kwigxalaba le-orc. Kuyafuneka ukugudisa imigca ebonisa igophe lezihlunu zakhe

I-Anti-aliasing akufanele idlule ngaphaya kwe-sprite eya kusetyenziswa kumdlalo okanye kwimvelaphi engaziwa umbala wayo. Ngokomzekelo, ukuba usebenzisa i-AA kwimvelaphi ekhanyayo, i-anti-aliasing iya kubonakala imbi kwimvelaphi emnyama.

6. Ulwandlalo olukhethiweyo

Ngaphambili, iinkcazo zazimnyama ngokupheleleyo, nto leyo eyenza ukuba i-sprite ibonakale i-cartoonish kakhulu. Umfanekiso wabonakala wahlulwe ngokwamacandelo. Ngokomzekelo, imigca emnyama kwingalo inikezela ngokungafaniyo kakhulu kwi-musculature, okwenza umlingiswa ubonakale ungaphantsi.

Ukuba i-sprite iba yinto yendalo kwaye i-segmentation ingabonakali, iimilo ezisisiseko zomlingiswa ziya kuba lula ukuzifunda. Ukwenza oku, ungasebenzisa ulwandlalo olukhethiweyo - ngokuyinxenye buyisela ulwandlalo olumnyama kunye nekhaphukhaphu. Kwinxalenye ekhanyisiweyo ye-sprite, ungasebenzisa imibala elula kakhulu, okanye, apho i-sprite ichukumisa indawo engafanelekanga, unokususa ulwandlalo ngokupheleleyo. Esikhundleni somnyama, kufuneka usebenzise umbala okhethiweyo kwisithunzi - ngale ndlela ukwahlula kuya kugcinwa (ukwahlula phakathi kwemisipha, uboya, njalo njalo).

Ndongeze ithunzi elimnyama kweli nqanaba. Isiphumo saba kumanqanaba amathathu oluhlaza eluswini lwe-orc. Umbala oluhlaza obumnyama kakhulu ungasetyenziselwa ulwandlalo olukhethiweyo kunye ne-AA.

7. Ukuchukunyiswa kokugqibela

Ekugqibeleni, kuyafaneleka ukongeza amanqaku aphezulu (awona mabala alula kwi-sprite), iinkcukacha (amacici, amacici, izibonda, amanxeba) kunye nolunye uphuculo de umlingiswa ulungele okanye ude uqhubele phambili ukuya kwelinye elilandelayo.

Kukho iindlela ezininzi eziluncedo ezinokusetyenziswa kweli nqanaba. Jikelezisa umzobo ngokuthe tye, oku kudla ngokunceda ukuchonga iimpazamo ngokwemilinganiselo kunye ne-shading. Unako kwakhona ukususa umbala-seta saturation kwi zero ukuqonda apho kufuneka utshintshe izithunzi.

Ukudala ingxolo (dithering, dithering)

Ukuza kuthi ga ngoku besisoloko sisebenzisa iindawo ezinkulu ezinomthunzi oqinileyo. Kodwa kukho enye indlela - i-dithering, ekuvumela ukuba uhambe ukusuka komnye umbala ukuya komnye ngaphandle kokongeza okwesithathu. Jonga lo mzekelo ungezantsi.

Umphezulu omnyama ukuya kukukhanya okhanyayo usebenzisa amakhulu eemibala ezahlukeneyo ezibhlowu.

I-gradient ephakathi isebenzisa imibala esithoba kuphela, kodwa kusekho izithunzi ezininzi zombala ofanayo. Kuvela into ebizwa ngokuba yi-banding (ukusuka kwi-English band - umgca), apho, ngenxa yemigca efanayo, iliso ligxininise kumanqaku oqhagamshelwano lwemibala, endaweni yemibala ngokwayo.

Kwi-gradient engezantsi sisebenzise i-dithering, enqanda ibhendi kwaye isebenzisa imibala emibini kuphela. Senza ingxolo yobukhulu obahlukeneyo ukulinganisa ukuhlelwa kombala. Obu buchule bufana kakhulu ne-halftone (i-halftone image) esetyenziswa kushicilelo; kunye nokumisa (umfanekiso oqingqiweyo) - kwimifanekiso kunye namahlaya.

Kwi-orc, ndiye ndadiza kancinci ukuhambisa ukuthungwa. Abanye abaculi be-pixel abayisebenzisi kwaphela, abanye, ngokuchaseneyo, abanazo iintloni kwaye bayenza ngobuchule kakhulu. Ndifumanisa ukuba i-dither ibonakala ingcono kakhulu kwiindawo ezinkulu ezizaliswe ngombala omnye (jonga esibhakabhakeni kwi-Metal Slug skrini ngasentla) okanye kwiindawo ezimele zibukeke zibuhlungu kwaye zingalingani (njengokungcola). Zigqibele ngokwakho ukuba uza kuyisebenzisa njani.

Ukuba ufuna ukubona umzekelo we-dithering enkulu kunye nomgangatho ophezulu, jonga imidlalo ye-Bitmap Brothers, isitudiyo saseBritane ukusuka kwi-80s, okanye imidlalo ekwikhompyuter ye-PC-98. Gcina nje engqondweni ukuba bonke bangama-NSFW.

Kukho imibala eyi-16 kuphela kulo mfanekiso!

8. Ukujonga kokugqibela

Enye yengozi yobugcisa be-pixel kukuba ibonakala ilula kwaye ilula (ngenxa yokwakheka kunye nokunciphisa isitayile). Kodwa uya kugqiba uchithe isixa esikhulu sexesha ucoca ii-sprites zakho. Kufana nephazili efuna ukusonjululwa- yiyo loo nto ubugcisa be-pixel butsala abantu abagqibeleleyo. Khumbula ukuba i-sprite enye akufuneki ithathe ixesha elininzi - sisiqwengana esincinci sengqokelela enzima kakhulu yamaqhekeza. Kubalulekile ukuba ungalahlekelwa ngumbono omkhulu.

Nokuba ubugcisa bakho be-pixel abuyiyo eyomdlalo, ngamanye amaxesha kufanelekile ukuba uzixelele, "Sele kulungile!" Kwaye uqhubeke. Eyona ndlela yokuphuhlisa izakhono zakho kukuhamba kuyo yonke inkqubo ukusuka ekuqaleni ukuya ekugqibeleni kaninzi kangangoko, usebenzisa izihloko ezininzi kangangoko.

Kwaye ngamanye amaxesha luncedo ukushiya i-sprite ixesha elithile ukuze ukwazi ukuyijonga ngamehlo amatsha kamva.

32x32 pixels

Senze i-pixel sprite enkulu eyi-96x96 kuqala kuba ngokobukhulu ifana nokuzoba okanye ukupeyinta, kodwa ngeepixels. Incinci i-sprite, ifana kancinci naleyo ifanele ukuboniswa, kwaye ibaluleke kakhulu ipixel nganye.

KwiSuper Mario Bros. Iliso likaMario lipikseli nje ezimbini, enye ingaphezulu kwenye. Nendlebe yakhe ngokunjalo. Umyili womlingiswa uShigeru Miyamoto uthe amadevu afunekayo ukwahlula impumlo ebusweni bonke. Ke enye yezona zinto ziphambili zikaMario ayiloyilo nje lomlinganiswa, kodwa licebo lepragmatic. Okuqinisekisa ubulumko obudala - "imfuneko ngumama wokuyila."

Amanqanaba aphambili okudala i-pixel sprite ye-32x32 sele iqhelekile kuthi: umzobo, umbala, izithunzi, ukucocwa ngakumbi. Kodwa kwiimeko ezinjalo, njengomzobo wokuqala, ndikhetha iimilo ezinemibala endaweni yokuzoba imizobo ngenxa yobukhulu obuncinci. Umbala udlala indima ebaluleke ngakumbi ekuchazeni umlinganiswa kunolwandlalo. Jonga uMario kwakhona, akanalo ulwandlalo konke konke. Akunjalo nje iidevu ezinomdla. Amanxeba akhe asecaleni achaza ukumila kweendlebe zakhe, imikhono yakhe ibonisa iingalo zakhe, kwaye imilo yakhe iyonke ichaza ngokucacileyo umzimba wakhe wonke.

Ukudala i-sprites encinci yi-compromise rhoqo. Ukuba wongeza i-stroke, unokuphulukana nendawo yesithunzi. Ukuba umlingiswa wakho uneengalo kunye nemilenze ebonakalayo ngokucacileyo, intloko mhlawumbi akufanele ibe nkulu kakhulu. Ukuba usebenzisa umbala, i-stroke ekhethiweyo, kunye ne-anti-aliasing ngokufanelekileyo, into enikezelweyo iya kubonakala inkulu kunokuba injalo.

Kwi-sprites encinci ndiyathanda isitayela se-chibi: iimpawu zibukeka zihle kakhulu, zineentloko ezinkulu kunye namehlo. Indlela enkulu yokwenza umlinganiswa onemibala kwindawo elinganiselweyo, kwaye ngokubanzi isitayile esihle kakhulu. Kodwa mhlawumbi kufuneka ubonise ukuhamba komlingiswa okanye amandla, ngoko unokunika indawo encinci entloko ukwenza umzimba ubonakale unamandla. Konke kuxhomekeke kwizinto ozikhethayo kunye neenjongo.

Iqela lonke lihlangene!

Iifomati zefayile

Esi siphumo sinokwenza nawuphi na umzobi we-pixel abe novalo

Umfanekiso owubonayo sisiphumo sokugcina umfanekiso kwiJPG. Enye idatha yalahleka ngenxa yoxinzelelo lwe-algorithms yefayile. Ubugcisa be-pixel obukumgangatho ophezulu buya kujongeka bububi, kwaye ukuyibuyisela kwi-palette yayo yoqobo akuyi kuba lula.

Ukugcina umfanekiso omileyo ngaphandle kokuphulukana nomgangatho, sebenzisa ifomathi yePNG. Ezoopopayi - GIF.

Ukwabelana njani ngokufanelekileyo ngobugcisa be-pixel

Ukwabelana ngobugcisa be-pixel kwiinethiwekhi zentlalo yindlela entle yokufumana ingxelo kwaye udibane namanye amagcisa asebenza ngesitayile esifanayo. Ungalibali ukusebenzisa i-hashtag #pixelart. Ngelishwa, iinethiwekhi zentlalo zihlala ziguqula i-PNG ibe yiJPG ngaphandle kokubuza, yenza amava akho abe mandundu. Ngaphezu koko, akusoloko kucaca ukuba kutheni umfanekiso wakho uguqulwe.

Kukho iingcebiso ezininzi malunga nendlela yokugcina ubugcisa be-pixel kumgangatho ofunekayo kwiinethiwekhi ezahlukeneyo zentlalo.

Twitter

Ukugcina ifayile yakho ye-PNG ingatshintshwanga kwi-Twitter, sebenzisa imibala engaphantsi kwama-256 okanye Qinisekaukuba ifayile yakho ingaphantsi kwe 900 pixels kwelona cala lide. Bendiya kwandisa isayizi yefayile ubuncinane 512x512 pixels. Kwaye ukwenzela ukuba ukulinganisa kukuphindaphinda kwe-100 (200%, kungekhona i-250%) kunye nemiphetho ebukhali igcinwe (Ummelwane okufuphi kwi-Photoshop).

Ii-GIF zoopopayi zeePosti zikaTwitter fanele ubunzima hayi ngaphezulu kwe-15 MB. Umfanekiso kufuneka ubuncinane 800x800 pixels, oopopayi looping kufuneka aphindaphinde kathathu, kwaye isakhelo lokugqibela kufuneka ibe sisiqingatha ubude bonke abanye - theory ethandwa kakhulu. Nangona kunjalo, akucaci ukuba ezi mfuno kufuneka zifezekiswe kangakanani, kuba i-Twitter ihlala iguqula i-algorithms yokubonisa umfanekiso.

Instagram

Ngokwazi kwam, akunakwenzeka ukuthumela umfanekiso kwi-Instagram ngaphandle kokulahlekelwa ngumgangatho. Kodwa ngokuqinisekileyo iya kujongeka ngcono ukuba uyayandisa ibe neepikseli ezingama-512x512 ubuncinci.
