Ungasifaka kanjani isithombe

vectorize isithombe iwumthombo othakazelisa kakhulu wabadwebi nabaklami, nakuba ingaba usizo kakhulu kubaculi bedijithali, abaklami bezimpawu nanoma yimuphi umsebenzisi osebenza ngezithombe zebhulogi yakhe yomuntu siqu noma izethulo ezichwepheshile. Kulokhu okuthunyelwe sichaza ukuthi kwenziwa kanjani.

Kodwa ngaphambi kokuphendula lo mbuzo, kubalulekile ukwazi ukuthi yini inqubo i-vectorization. Izithombe eziningi esizithola ku-inthanethi noma esizilayisha kumakhompyutha ethu zenziwe ngamachashazi noma amaphikseli. Lokho kusho ukuthi usayizi wayo mkhulu futhi imisebenzi yokuhlela ihamba kancane futhi iyinkimbinkimbi. Ngakolunye uhlangothi, izithombe zevekhtha (ezikhiqizwe kusetshenziswa amafomula ezibalo) zinosayizi omncane kakhulu futhi zingasetshenzwa ngokuguquguquka okwengeziwe.

Kodwa into engcono kakhulu ngezithombe ze-vector yilokho Angashintshwa usayizi ngaphandle kokulahlekelwa ikhwalithi. Uma kuqhathaniswa nalezo ezakhiwe ngamaphikseli, izithombe ezenziwe nge-vectorized zigcina ukubukeka kwazo kwangempela, ngencazelo ephelele, lapho sikhulisa noma sinciphisa usayizi wazo. Ngale ndlela sivimbela isithombe ukuthi singaveli sinamaphikseli uma senza noma yiziphi izinguquko kuso.

Yini eyenza isithombe sibe yi-vector?

Inqubo ye-vectorization iyadlula guqula izithombe ezakhiwe ngamaphikseli zibe izithombe ezakhiwe ama-vectors. Ngobuchwepheshe, kuhlanganisa ukuguqula lawo maphikseli abe imigqa, amajika namaphoyinti. Ngakho, isithombe ebesikade siyibhulokhi eyodwa siba isethi yamabhulokhi angahlelwa ngawodwana. Ngale ndlela kungenzeka ukufeza umsebenzi wokuhlela onembe kakhudlwana nokukala.

Ifayela eliwumphumela wenqubo ye-vectorization ligcinwa ochungechungeni lwamafomethi athile: i-CDR, i-AI, i-SVG ne-EPS, ikakhulukazi.

Kunamasu ahlukene okwenza isithombe se-vector: kusukela ekudwebeni amapholygoni nemigqa, ukugcwalisa isithombe ngombala. Kodwa-ke, uma sikhuluma ngokwenza isithombe esivele sivele sikhona, okungukuthi, ukuguqula isithombe se-bitmap sibe i-vector, kunezindlela ezimbili kuphela zokukwenza:

• Ukudweba izimo zemigqa namajika wesibalo se-vector esithombeni.
• Usebenzisa i- ithuluzi le-auto vectorization. Yenza izinhlelo zokuhlinzeka zenze isithombe esisha ngefomethi ye-vector ngokusekelwe esithombeni sokuqala.

Uma ukuguqulwa sekuqediwe, umphumela wokugcina usengacwengwa kakhudlwana ngokuveza izimo zawo, uthonye ukushuba kombala, ukuthambisa noma ukugcizelela imigqa yawo, njll.

Amathuluzi ukuze vectorize izithombe

Manje njengoba sesazi ukuthi ziyini izithombe ezine-vectorized nokuthi yiziphi izindlela ezisetshenziswayo ukwenza i-vectorization, sekuyisikhathi sokukhetha ithuluzi elingakusiza kangcono ukukufeza lokho. Nazi ezinye ezihamba phambili:

Umdwebo we-Corel

Abaklami bezithombe abaningi emhlabeni wonke, kokubili abangafundile nabaqeqeshiwe, basebenzisa njalo Umdwebo we-Corel. Lolu hlelo lungasetshenziswa futhi ukudala nokuhlela izithombe ze-vector. Uma sesiyifakile kukhompyutha yethu, inqubo ye-vectorization ilula kakhulu, vele ulandele lezi zinyathelo:

1. Okokuqala, sivula uhlelo lwe-Corel Draw bese sidala ifayela elisha,
2. Ngemuva kwalokho kufanele ngenisa isithombe esifuna ukwenza i-vectorize (amafomethi e-PNG noma e-JPEG avumelekile).
3. Sichofoza esithombeni bese ukhetha inketho IBitmap.
4. Okulandelayo, sikhetha "Contour Tracing", emva kwalokho iwindi liyavuleka lapho ungahlela khona i-vector.
5. Uma umsebenzi wokuhlela usuqediwe, sichofoza isithombe futhi bese siyakhetha "Hlela" y "Hlukanisa iqembu."

I-Inkscape

Ithuluzi elikhulu lamahhala lokudala izithombe ze-vector. Nge-Inkscape akunakwenzeka ukwenza isithombe ku-inthanethi, kuyadingeka ukulanda uhlelo. Ukusebenza nayo kulula kakhulu, kufanele nje ulayishe isithombe ofuna ukusebenza ngaso bese uchofoza kuso "Vectorize Bitmap".

Kunezihlungi ezintathu ezihlukene okufanele zisetshenziswe: umkhawulo wokukhanya, ukutholwa konqenqema nokwandiswa kombala. Eyokuqala isebenzisa i-algorithm elinganisa okuqukethwe kwechromatic kwephikseli ngayinye ukuze ihlukanise izigaba ezimbili; isihlungi sesibili sisetshenziselwa ukukhiqiza i-bitmap emaphakathi lapho singalungisa khona ubumnyama nokujiya konqenqema lwesithombe esivezwayo; ekugcineni, isihlungi sokugcina sinquma ukuthi mingaki imibala yokuphumayo ukuze ifake umbala ku-bitmap.

Kubukeka kuyinkimbinkimbi, kodwa empeleni kulula kakhulu. Kufanele nje uzame isihlungi ngasinye salezi futhi ubone ukuthi yisiphi esisinikeza umphumela ongcono kakhulu esimweni ngasinye.

Umfanekisi

Isiphakamiso sethu sesithathu sithi I-Adobe Illustrator, enye yezinhlelo ezidume kakhulu zokudala nokuhlela ama-vector, ezikwazi ukunikeza imiphumela yezinga lochwepheshe, kodwa ngesikhathi esifanayo lapho ifinyeleleka kunoma yimuphi umsebenzisi, kungakhathaliseki ukuthi banolwazi olungakanani.

Ungasifaka kanjani isithombe ku-Illustrator? Lezi yizinyathelo okumele uzilandele:

1. 1. Okokuqala siqala uhlelo lwe-Adobe Illustrator bese sichofoza "Dala ifayela elisha."
   2. Bese sikhetha isithombe ukuze vectorize ngokusebenzisa inketho "faka ifayela".
   3. Okulandelayo, siya esithombeni bese uchofoza Ukulandelela Isithombe, isithonjana sakhe esimise okomcibisholo sitholakala kubha engaphezulu.
   4. Esikrinini esilandelayo, lapho kuboniswa khona izitayela ezahlukene ze-vectorization, siqala ngokukhetha "Isithombe Sokuthembeka Okuphezulu" bese uchofoza inkinobho "Nweba".
   5. Ukuze siqedele inqubo, sichofoza inkinobho yegundane kwesokudla bese ukhetha "Hlukanisa iqembu."
