Ungawenza njani umfanekiso

Vectorize umfanekiso sisixhobo esinomdla kakhulu kubazobi nabayili, nangona inokuba luncedo kakhulu kumagcisa edijithali, abaqulunqi belogo kunye nawuphi na umsebenzisi osebenza ngemifanekiso yebhlog yakhe okanye intetho yobuchwephesha. Kule post sichaza indlela yokwenza.

Kodwa ngaphambi kokuba uphendule umbuzo, kuyimfuneko ukwazi ukuba yintoni inkqubo vectorization. Uninzi lwemifanekiso esiyifumana kwi-Intanethi okanye esiyifake kwiikhompyuter zethu yenziwe ngamachaphaza okanye iipikseli. Oko kuthetha ukuba ubukhulu bayo bukhulu kwaye imisebenzi yokuhlela iyacotha kwaye inzima. Ngakolunye uhlangothi, imifanekiso ye-vector (eyenziwe kusetyenziswa iifomyula zemathematika) inobungakanani obuncinci kwaye inokusetyenzwa ngokuguquguquka okukhulu.

Kodwa eyona nto ilungileyo malunga nemifanekiso ye-vector yileyo Zinokutshintshwa kwakhona ngaphandle kokulahlekelwa ngumgangatho. Xa kuthelekiswa nezo zenziwe ngeepikseli, imifanekiso ye-vectorized igcina ukubonakala kwayo kwasekuqaleni, kunye nenkcazo epheleleyo, xa sinyusa okanye sinciphisa ubungakanani babo. Ngale ndlela sithintela umfanekiso ukuba ungaveli uhlaziywe xa sisenza naluphi na utshintsho kuwo.

Yintoni ukuvelisa umfanekiso?

Inkqubo ye-vectorization iyahamba guqula imifanekiso eyenziwe ngeepixels ibe yimifanekiso eyenziwe ziivektha. Ngokobuchwephesha, ibandakanya ukuguqula ezo pixels zibe yimigca, iigophe kunye namanqaku. Ngaloo ndlela, umfanekiso owawusakuba yibhloko enye uba yiseti yeebhloko ezinokuthi zihlelwe ngokwazo. Ngale ndlela kunokwenzeka ukufezekisa umsebenzi ochanekileyo wokuhlela kunye nokulinganisa.

Ifayile ephuma kwinkqubo ye-vectorization igcinwa kuluhlu lweefomathi ezithile: i-CDR, i-AI, i-SVG kunye ne-EPS, ngokukodwa.

Kukho iindlela ezahlukeneyo zokwenza umfanekiso wevector: ukusuka kwimizobo yeepolygoni kunye nemigca, ukuzalisa umfanekiso ngombala. Nangona kunjalo, xa sithetha malunga nokuguqula umfanekiso okhoyo, okt ukuguqula umfanekiso we-bitmap kwi-vector, zimbini kuphela iindlela zokuyenza:

• Ukuzoba imilo yemigca kunye neegophe zomfanekiso we-vector kumfanekiso.
• Sebenzisa i- isixhobo sokwenza i-auto vectorization. Yenza unikezelo lweenkqubo zenze umfanekiso omtsha kwifomathi yevektha esekwe kumfanekiso wokuqala.

Emva kokuba ukuguqulwa kugqityiwe, isiphumo sokugqibela sisenokucocwa ngakumbi ngokucacisa imilo yayo, ukuphembelela ubunzulu bombala, ukuthambisa okanye ukugxininisa imigca yayo, njl.

Izixhobo zokuvektha imifanekiso

Ngoku siyazi ukuba yeyiphi imifanekiso evectorized kwaye zeziphi iindlela ezisetyenziselwa ukwenza i-vectorization, lixesha lokukhetha isixhobo esinokukunceda ukuba usifezekise. Nazi ezinye zezona zibalaseleyo:

Umzobo wobugcisa

Uninzi lwabayili bemizobo kwihlabathi liphela, bobabini abangabaziyo kunye neengcali, bahlala besebenzisa Umzobo wobugcisa. Le nkqubo inokusetyenziselwa ukwenza kunye nokuhlela imifanekiso yevektha. Nje ukuba siyifake kwikhompyuter yethu, inkqubo ye-vectorization ilula kakhulu, landela la manyathelo:

1. Ukuqala, sivula inkqubo yeCorel Draw kwaye senze ifayile entsha,
2. Emva koko kufuneka ngenisa umfanekiso ukuba sifuna ukuvektha (iifomati zePNG okanye zeJPEG ziyasebenza).
3. Sicofa kumfanekiso kwaye ukhethe ukhetho IBitmap.
4. Emva koko, sikhetha "Umkhondo weContour", emva kokuba iwindow ivula apho unokuhlela i-vector.
5. Emva kokuba umsebenzi wokuhlela ugqityiwe, sicofa umfanekiso kwakhona kwaye ukhethe "Lungelelanisa" y "Yahlula amaqela."

Inkscape

Isixhobo esikhulu sasimahla sokwenza imifanekiso ye-vector. Nge-Inkscape akunakwenzeka ukwenza umfanekiso we-intanethi kwi-intanethi, kuyimfuneko ukukhuphela inkqubo. Ukusebenza nayo kulula kakhulu, kufuneka ulayishe umfanekiso ofuna ukusebenza nawo kwaye ucofe kuwo "Vectorize Bitmap".

Kukho izihluzo ezithathu ezahlukeneyo zokusebenzisa: Ukukhanya kokukhanya, ukubonwa komphetho kunye nokwandiswa kombala. Eyokuqala isebenzisa i-algorithm elinganisa umxholo wechromatic wepixel nganye ukuwahlela ngokweendidi ezimbini; isihluzo sesibini sisetyenziselwa ukwenza i-bitmap ephakathi apho sinokunyenyisa ubumnyama kunye nobukhulu becala lomfanekiso owenziweyo; Okokugqibela, icebo lokucoca lokugqibela lithatha isigqibo sokuba mingaphi imibala yemveliso ekhoyo yokufaka umbala kwi bitmap.

Ikhangeleka intsonkothile, kodwa eneneni ilula kakhulu. Kufuneka nje uzame nganye yezi zihluzo kwaye ubone ukuba yeyiphi esinika esona siphumo silungileyo kwimeko nganye.

Umzekeliso

Isiphakamiso sethu sesithathu sithi Adobe Illustrator, enye yeenkqubo ezidumileyo zokwenza kunye nokuhlela ii-vectors, ezikwazi ukubonelela ngeziphumo zezinga lobuchwephesha, kodwa kwangaxeshanye ekufikeleleni kuye nawuphi na umsebenzisi, naluphi na ulwazi lwabo.

Uwenza njani umfanekiso kwi-Illustrator? La ngamanyathelo ekufuneka uwalandele:

1. 1. Okokuqala siqala inkqubo ye-Adobe Illustrator kwaye nqakraza "Yenza ifayile entsha."
   2. Emva koko sikhetha umfanekiso ukuze uvectorize ngokusebenzisa ukhetho "faka ifayile".
   3. Emva koko, siya kumfanekiso kwaye nqakraza Umkhondo womfanekiso, iqhosha elimilise okwetolo lifunyenwe kwibar ephezulu.
   4. Kwisikrini esilandelayo, apho iindlela ezahlukeneyo zevectorization ziboniswa, siqala ukukhetha "Ifoto yokuthembeka okuphezulu" kwaye emva koko ucofe iqhosha "Yandisa".
   5. Ukugqiba inkqubo, sicofa iqhosha lemouse ekunene kwaye ukhethe "Yahlula amaqela."
