Amanothi umklami: yini umfanekiso we-vector, futhi yiziphi izinzuzo zayo?

Ngokuqinisekile wonke umuntu wezwa raster kanye Vector izithombe. Nokho, bayehluka bodwa? Eqinisweni, kwakheka isithombe Vector is kusukela inqwaba ngazinye, izinto uyakaleka. Ngokungafani raster, bazimisele usebenzisa zibalo ekhethekile zezibalo. Lokhu kusho ukuthi Vector izithombe ukugcina eliphezulu kuzo zonke izimo. I lezinto ngokwazo kungase kuhilele Curves kanye imigqa eqondile nomumo. izakhiwo zabo eziyinhloko umbala, Ukufiphaza, futhi ukunquma nentaba. Njengoba uma umsebenzisi ushintshe noma iyiphi yalezi izakhiwo, into akuyona uhlanekezelwe noma zikhubazekile.

Inzuzo enkulu Vector izithombe - ithuba ngandlela-thile ukushintsha osayizi yabo. Imigqa izohlala abukhali futhi ecacile esikrinini banoma iyiphi isayizi, futhi ukuphrinta. Ngokwesibonelo, yonke amafonti Vector izinto. Ngaphezu kwalokho, ngokungafani bitmaps, basuke akugcini kumumo elingunxande.

I ethile kuphela ukuthi angasetshenziswa hhayi ukudala izithombe photorealistic. Ngokuvamile, basebenzisa gradients ahlanzekile kanye nemibala. Okungukuthi, imibala inguquko esinjalo, okuyinto ejwayelekile izithombe namanje ngeke ujike ukukuzuza. Nokho, kungenzeka ukuthi esikhathini esizayo esiseduze lokhu kuzoshintsha. Uma kuqhathaniswa neminyaka eyedlule, ubuchwepheshe yokudala Vector izithombe is ngcono kakhulu.

abaculi Contemporary nabaqambi ungakwazi zizame izinto okusobala, izithunzi, ukuhamba kalula futhi ukwakheka ngisho raster, ekufezeni engokwemvelo nangokuzimisela okukhulu kunangaphambili. Muva nje, le-vector izithombe Uhlanganise kuphela cartoon izithombe. Manje bangabafowethu ezivumelana imiqondo okwangempela.

Vector izithombe kungenziwa rasterized ngaphandle kwezinkinga. Inqubo okuphambene nalokho nakho kungenzeka, kodwa luyindida ukuze lelisu okuningi. Ngakho-ke, uma udinga ukuba isithombe rasterized, hhayi lazy kakhulu ukugcina umthombo Vector ngokwehlukile. Uma kamuva udinga ukukopisha isithombe bitmap esekelwe entry efanayo, kodwa emikhulu, ungakwazi kalula ukuthole. Futhi ungakhohlwa ukuthi uma isithombe Vector ukuvula uhlelo ukusingatha ezinye izinhlobo amafayela, uzophiwa ngokuzenzakalelayo ukushintsha uhlobo yayo futhi ulahlekelwe impahla yabo ehlukile. Ukuze ugweme lokhu, qaphela uma kukhethwa isofthiwe.

Kukhona nezakhiwo olukhethekile Vector izithombe. Khona-ke abakhululiwe emikhulu CDR (CorelDRAW), CGM, WMF, AI (i-Adobe Illustrator), CMX (Corel Exchange) kanye DXF CAD.

Ngokuvamile, i-vector ngefomethi yesithombe kungenziwa kuphela wavula ohlelweni oluthile. Lezi abahleli, ngokungafani kuya raster, ngokuvamile okushayisanayo nomunye, ngakho ukuthola isithombe undistorted kunzima.

Vector isithombe ngempela ezidingekayo uma sikhuluma ukudalwa izinhlelo, imidwebo, amalogo, design amawebhusayithi. Abaculi nabaqambi emhlabeni wonke ngenkuthalo ayisebenzise ngezinhloso ezehlukene. Naphezu alula sobala, Vector isithombe ukusebenza kakhulu, futhi ngokuvamile kuba nezimo lapho ukusetshenziswa bitmap akunakwenzeka.
