Sau ntawv ntawm tus qauv tsim: dab tsi yog vector duab thiab dab tsi yog nws qhov zoo?

Muaj tseeb txhua tus neeg tau hnov txog raster thiab vector dluab. Txawm li cas los xij, lawv ua li cas sib txawv ntawm lawv tus kheej? Qhov tseeb, vector duab yog tsim los ntawm ntau tus neeg ntawm cov khoom scalable. Tsis zoo li raster ones, lawv raug txiav txim siab los ntawm kev siv cov zauv tshwjxeeb. Qhov no txhais tias vector dluab khaws zoo zoo nyob rau hauv tag nrho cov mob. Cov khoom ntawm lawv tus kheej muaj peev xwm muaj cov curves thiab cov kab ncaj nraim thiab duab. Cov khoom tseem ceeb yog xim, sau thiab contour. Tsis muaj teeb meem li cas tus neeg hloov cov khoom no, qhov khoom tsis distorted lossis deformed.

Lub ntsiab kom zoo dua cov vector dluab yog rab peev xwm los hloov kev hloov qhov ntau thiab tsawg. Cov kab yuav nyob twj ywm ntse thiab ob qho tib si ntawm qhov kev tshuaj ntsuam ntawm ib qho me me twg, thiab thaum twg luam tawm. Piv txwv, tag nrho cov ntawv sau muaj vector khoom. Tsis tas li ntawd, tsis zoo li cov dluab ntawm cov duab bitmap, lawv tsis muaj cwj ciam rau ib lub duab.

Qhov teeb meem tseem ceeb tsuas yog tias lawv tsis tuaj yeem siv los tsim cov duab dluab. Raws li txoj cai, lawv siv dawb gradients thiab xim. Ntawd yog, xws li kev hloov ntawm tones, uas yog raug rau cov duab, tsis tau tiav. Txawm li cas los xij, nws yuav zoo dua yog qhov no yuav hloov yav tom ntej. Piv nrog rau cov xyoo dhau los, cov cuab yeej tsim vector dluab tau ho tau zoo tuaj.

Niaj hnub nimno cov neeg ua yeeb yam thiab cov neeg tsim qauv yuav sim nrog cov khoom ci, cov duab ntxoov ntxoo, cov duab hloov tshiab thiab cov ntawv raster txawm, ua tau zoo dua qub. Kom tsis ntev los no, vector dluab tau txuam nrog cov duab tas luav xwb. Tam sim no lawv muaj ntau thiab ntau raws li qhov kev xav ntawm kev ua neej.

Daim duab vector yuav hloov dua siab tshiab rau ib qho tsis muaj teebmeem. Cov txheej txheem rov qab los kuj tseem ua tau, tab sis nws yog ib qho kev txiav txim ntawm qhov ntau tshaj qhov ua tiav hlo. Yog li, yog tias koj xav tau rasterize ib daim duab, tsis txhob yuav tub nkeeg los cawm tus vector qhov chaw cais. Yog hais tias tom qab ntawd koj yuav tau luam ib bitmap duab raws li cov tib nkag teb chaws, tab sis loj dua, koj yuav tau yooj yim tau nws. Tsis tas li ntawd, tsis txhob hnov qab tias yog vector duab qhib rau hauv qhov kev pab cuam los ua cov ntaub ntawv ntawm lwm hom, nws yuav cia li hloov nws hom thiab poob nws cov khoom tshwj xeeb. Yuav zam tau qhov no, ceev faj thaum xaiv software.

Muaj ntau yam tshwj xeeb rau cov vector dluab. Cov tseem ceeb yog CDR (CorelDRAW), CGM, WMF, AI (Adobe Illustrator), CMX (Corel Txauv) thiab DXF CAD.

Feem ntau cov feem ntau, ib tug vector hom duab yuav tsuas yuav qhib nyob rau hauv ib lub qhov kev pab cuam. Cov editors, tsis zoo li raster ones, feem ntau sib tawm tsam nrog txhua lwm, yog li tau txais ib daim duab undistorted yuav problematic.

Vector image yog tiag tiag tsim nyog, thaum nws tawm los tsim cov kev npaj, kos duab, logos, tsim ntawm cov websites. Cov yeeb yaj kiab thiab cov neeg tsim qauv thoob ntiaj teb nquag siv nws rau ntau lub hom phiaj. Dua li nws txoj kev sim yooj yim, cov vector duab tsis tshua zoo, thiab feem ntau muaj ntau zaus uas siv lub bitmap tsuas ua tsis tau.
