Yintoni umhleli yemizobo kumda wesangqa

Kuba processing of imifanekiso kunye nokudala imizobo usebenzisa ikhompyutha yeraster kunye kumda wesangqa iziqhubekisi, ezo indlela eyahlukileyo khowudi (format) kunye nokumelwa lolwazi lomzobo.

abahleli yemizobo Raster

Abahleli usebenzisa dot (pixel) umelo lo mfanekiso, ngenxa yesi sizathu kuthiwa yeraster (bitmepovymi, bit), kwaye zenzelwe ukuba kuqhutyekekwe iifoto yedijithali okanye imifanekiso zaskenwa.

Ibitmaps ezi lanje matrix okanye ngegridi, ngokuqhelekileyo amanqaku umbala uxande (pixels) kwi izikrini-liso kunye izixhobo ukubonisa okanye ephepheni. Iimpawu eziphambili zezi imifanekiso na ubukhulu, xa pixels, ubunzulu besuntswana (imifanekiso ubunzulu besuntswana) imodeli umbala / isithuba (CMYK, RGB, sampling, xyz et al.) Yaye isisombululo (inani umfanekiso amanqaku ayi indawo unit okanye ubude).

Umzekelo ezaziwa umhleli bitmap, Kakade ke, achazayo (noko) inkqubo Photoshop kunye "umdala" kwi Microsoft - Paint Editor.

abahleli yemizobo Vector

Ukudala nemizobo enzima nemida ngqo, ezintsonkothileyo ecacileyo zisetyenziswa ikakhulu umhleli yemizobo kumda wesangqa, enye yezixhobo ephambili kuzo Bezier ezigoso, ukuvumela ukuba ukuzoba ezigoso (imigca baphuke, ngqo kunye agudileyo) amakhulu kunye nokubekwa ngqo esiludumbo (support) amanqaku, kunye nolawulo phezu ukuma kwilungu ngalinye.

Bezier curve angamelwa ngenxa translational shape iinkcukacha yepholigoni, imilo umgca belinganisa uqhagamshelwano uthotho Amanqaku okulawula. Ijika, ukusuka loqalo lwencopho polygon esiphelweni sayo, uthathele ingqalelo njenge umazibuthe wakhe, ukuba intermediates ukuchaza iindawo ifomu inkxaso, apho ngokwayo aluphumeleli.

Ngenxa kwiipropati awodwa, lula lo msebenzi ithuba okulawula Bezier ezigoso ziya zisetyenziswa kakhulu kukhombisa ezigoso kwamagingxi-computer.

Le yokugcina izixhobo ezigcinwe ngamnye yemizobo kumda wesangqa, basoloko langoku, "Ukwanelisa", "umbhalo", "ipensile" kunye iseti olusisiseko iimilo zejiyometri (okt. N. primitives), nto leyo isisiseko ezininzi yoyilo graphic.

Uchitha, njengokuba kwi abahleli bitmap, amabala iindawo limited chaza umbala (okanye ithambeka).

Ukudala isixhobo itekisi efanelekileyo ithotyiweyo aze ke atshintshelwe ezigoso ukuqinisekisa ukuzimela umfanekiso ukudala imigca ukuba ziyafumaneka (okanye akafumaneki) kwi computer esetyenziselwa ukubukela.

Ipensile ukwenza ngokwencwadi umgca nge inani elikhulu lamanqaku ezingundoqo, ezithi ke ngoko isuswe ngokusebenzisa itheko elilodwa eliququzelela igophe.

Amandla kunye nobuthathaka ngama kumda wesangqa

Images ikuvumela ukuba ukudala umhleli yemizobo kumda wesangqa, Ziliqela izinto ezibalulekileyo phezu imifanekiso yeraster, eyona ibaluleke ngakumbi kuzo zezi zilandelayo:

• ukunyusa okanye ukuncipha imizobo kumda wesangqa ngokupheleleyo aluchaphazeli ecacileyo imida kunye imisele;
• iifayile umfanekiso yomzobo zinobunzima obungaphantsi, ceteris paribus;
• Vector imifanekiso ngaphandle izinto yeraster nzima, zisebenzisa umthamo encinci le kwinkumbulo yekhomputha ngaphezu ibitmaps efanayo;
• imifanekiso Vector ukuba uzakukalishwa kwaye similise ngaphandle kokulahleka umgangatho, njengoko kwakhiwa neenkcazo zemathematika izinto, imigca kunye izangqa;
• nayiphi umhleli kumda wesangqa ikuvumela ukunyenyisa amacandelo ngamnye yepateni ngaphandle echaphazela eminye iziqalelo mfanekiso, ngaloo ndlela zokuzoba izinto kungenzeka ngaphandle kokuphazamisa omnye komnye;
• kwiimeko ezithile yaye phantsi kweemeko ezithile yinto enokwenzeka ukuguqula imifanekiso eyi ibe kumda wesangqa.

Ngokumalunga aluyandisisyo kumda wesangqa ukumelwa ingcaciso yomfanekiso, eyona ibaluleke ngakumbi kuzo buhlobene "phandle" iinkalo eziphambili yemizobo kumda wesangqa, kunye nendalo, njengokuba sisazi, siphephe imigca ethe ngqo. Ngoko ke, umhleli yomzobo "uyala ukuthatha imiyalelo 'ukudala elihle, imizobo olusengqiqweni.

Izinto eziluncedo nezingeloncedo of imifanekiso ye bitmap

Izinto eziluncedo ezingundoqo abahleli yeraster elula ukukwazi ukwenza imifanekiso photo-zinjalo, ukusukela, ngenxa kwezinga siseko lokwakha imifanekiso, pixel ngalinye kunikwa nasiphi na izigidi abangasekhoyo.

Bobubi eziphambili yemizobo ye bitmap zithathwa neentsilelo scalability kunye nenguqu ngaphandle kokulahleka umgangatho, kwakunye ubunzima amakhulu yeefayile ukuxhomekeka kwabo kakhulu kwi zikumfanekiso wobunjani.

Uphononongo Uthelekiso lomhleli kumda wesangqa

Namhlanje, abayili, amagcisa kunye nabasebenzisi eqhelekileyo ayikwazi akhalaze ngenxa yokunqongophala kwezibonelelo software ukuqonda izimvo zabo zokuyila nokuba ukulungisa. Oku kukwasebenza abahleli kumda wesangqa, iinqobo eziphambili merit apho abanye lo ukusebenza, kodwa abanye - ukufumaneka (abahlawulwa / free).

Phakathi iinkqubo ezamahala Eziqhelekileyo zimelwe Dia, OpenOffice.org Zoba, sK1 (ifolokhwe Skencil), Inkscape, Xara Xtreme for Linux, Skencil (ex-Sketch), Sodipodi, Expression Design, Pivot Stickfigure nokuveza, kunye Alchemy.

Kwezi, kuphela Linux ubaleka umhleli sK1 kumda wesangqa (ifolokhwe Skencil), kwi-Linux OS X yokusebenza inkqubo Xara Xtreme kunye Skencil, abahleli eyenzelwe Expression Windows Design kunye Pivot Stickfigure nokuveza, kwaye wonke umntu - cross-eqongeni.

Le nkqubo 'cool "ithandwa kwaye esebenza Kakade ke, ihlawulwe. Olu luhlu luquka i abahleli Adobe Flash, Adobe Illustrator, Adobe FreeHand (Windows; OS X), kunye CorelDRAW kunye Xara uMyili PRO (Windows).

Ngubani emhlabeni yonke mnandi

Ukuba abahleli vector wabuza kwisipili "ngubani emhlabeni zonke zimnandi," kunokwenzeka ukuba, waphendula wathi: "Umhle, akukho mathandabuzo, 'isipili kuya kuzenza:" kodwa Coreldraw esiyua umhleli zonke zimnandi ... ". Ngenye indlela, nenxenye elungileyo abasebenzisi, kubandakanywa iingcali, ndiyavumelana nawe.

Coreldraw umhleli graphic iqukwe kwiphakheji, leyo luguqulelo 10 igama Coreldraw Graphics Suite. Coreldraw Ukongeza, lo mqulu olu xwebhu umhleli womzobo Corel Photo-Paint (bitmap), inkqubo itshintsha imifanekiso eyi zibe ifomati kumda wesangqa Corel Symmetry, nokuveza Corel RAV E kunye Corel Cupture ukutshintshela imifanekiso esuka kwikhompyutha ngqo ifayile okanye eqhotyoshwayo Windows.

Loud uzuko umhleli Coreldraw ibopheleleke kuphela ukuba kakhulu ukusebenza kwakhe, kodwa ithala kakhulu imifanekiso esele zenziwe, kunye software eyakhelwe-ngaphakathi inkqubo enamandla woqeqesho kunye amacebiso. Ukongeza, umhleli unendlela ngokungabi analogue kwi "oogxa".
