Bitmap thiab vector yog ob hom duab pom hauv online lossis raws li hom duab txhawb nqa hauv software software. Nws yuav luag tsis yooj yim sua los tham txog cov duab kos duab yam tsis tau tsim kev nkag siab txog qhov sib txawv ntawm ob hom 2D duab loj. Thaum ob qho tib si yog hom duab thiab siv rau lub hom phiaj zoo sib xws, peb tau nkag mus tob kom pom qee qhov tsis sib xws. Ob hom ntawv ua haujlwm sib txawv ntawm ib leeg thaum koj tshuaj xyuas lawv ze.
Kev Tshawb Nrhiav Txhua Yam
- Ua duab.
- Ntau scalable yam tsis poob zoo.
- Kev siv tshwj xeeb ntxiv.
- Ua ntawm pixels.
- Compatible nrog Microsoft Paint, Adobe Photoshop, Corel Photo-Paint, Corel Paint Shop Pro, thiab GIMP.
- Poob qhov zoo thaum daim duab loj dua.
Vector thiab bitmap dluab yog ob qho tib si duab ntawm ib qho screen, tab sis lawv muaj sib txawv compositions thiab tsom. Bitmaps yog tsim los ntawm pixels, thaum cov duab vector yog software tsim thiab raws li kev suav lej.
Bitmaps tsis yog ntau dua hauv lub neej niaj hnub tab sis siv tau yooj yim dua. Koj tuaj yeem hloov ib hom ntawv ntawm cov duab bitmap mus rau lwm qhov, thiab koj tsis tuaj yeem tig ib daim duab rau hauv vector yam tsis muaj software tshwj xeeb.
Vector cov duab feem ntau smoother thiab siv tau ntau dua, thiab koj tuaj yeem ntsuas lawv dawb yam tsis muaj kev txi zoo. Feem ntau, vectors yog rau kev ua cov ntaub ntawv ua haujlwm scalable, thaum bitmap yog rau kev sib koom ua ke kawg khoom.
Formats: Bitmaps Muaj Ntau Ntxiv
- suav nrog AI, CDR, CMX (Corel Metafile Exchange Image), SVG, CGM (Computer Graphics Metafile), DXF, thiab WMF (Windows Metafile).
- suav nrog GIF, JPG, PNG, TIFF, thiab PSD.
Vectors yog cov ntaub ntawv tshwj xeeb dua thiab zoo li yuav tshwm sim hauv cov hom tsis tshua muaj. Txhua daim duab uas koj pom hauv koj lub xov tooj, ntsiav tshuaj, lossis lub computer yog daim duab qhia chaw, txawm tias ib tus neeg tsim nws siv cov cuab yeej vector.
Bitmap dluab (tseem hu ua raster dluab) yog tsim los ntawm pixels nyob rau hauv ib daim phiaj. Pixels yog cov duab kos duab, cov duab plaub me me ntawm cov xim ntawm tus kheej uas ua rau koj pom ntawm qhov screen. Tag nrho cov squares ntawm cov xim no tuaj ua ke los tsim cov duab koj pom.
Txawm hais tias tsis yog siv ntau li cov duab kos duab, cov duab vector muaj ntau yam tsim txiaj. Vector dluab yog tsim los ntawm ntau tus neeg, khoom scalable. Lawv ib txwm ua ntawm qhov zoo tshaj plaws vim tias lawv yog cov khoom siv ywj pheej. Cov khoom hauv cov duab vector yuav muaj cov kab, nkhaus, thiab cov duab nrog cov yam ntxwv kho tau xws li xim, sau, thiab cov qauv.
Yooj Yim Ntawm Kev Siv: Vectors Muaj Zog
- Resolution-independent.
- Qhov siab tshaj plaws tsis hais qhov ntsuas.
- Poob zoo thaum scaling.
- Yooj yim mus los ntawm vector rau bitmap dua li lwm txoj kev.
Vim tias bitmaps yog kev daws teeb meem-nyob, nws tsis tuaj yeem nce lossis txo lawv qhov loj me yam tsis muaj kev cuam tshuam cov duab zoo. Thaum koj txo qhov luaj li cas ntawm daim duab bitmap los ntawm koj cov software resample lossis resize xaiv, pixels yuav tsum muab pov tseg.
Thaum koj nce qhov loj ntawm daim duab bitmap, software tsim cov pixels tshiab. Thaum tsim pixels, software yuav tsum kwv yees cov xim qhov tseem ceeb ntawm cov pixels tshiab raws li cov pixels nyob ib puag ncig. Cov txheej txheem no hu ua interpolation.
Yog tias lub pixel liab thiab xiav pixel nyob ib sab ntawm ib leeg thiab koj muab ob npaug rau qhov kev daws teeb meem, ob lub pixels yuav raug ntxiv ntawm lawv. Interpolation txiav txim seb cov xim twg ntxiv pixels yuav yog; lub khoos phis tawj ntxiv qhov nws xav tias yog xim raug.
Scaling ib daim duab tsis cuam tshuam cov duab mus tas li. Hauv lwm lo lus, nws tsis hloov tus naj npawb ntawm pixels hauv daim duab. Qhov nws ua yog ua kom lawv loj dua. Txawm li cas los xij, yog tias koj teev cov duab bitmap rau qhov loj dua hauv koj nplooj ntawv layout software, koj yuav pom qhov tseeb jagged tsos. Txawm hais tias koj tsis pom nws ntawm koj lub vijtsam, nws yuav pom tseeb hauv cov duab luam tawm.
Scaling a bitmap image to a me me is not have any effect. Thaum koj ua qhov no, koj nce PPI ntawm daim duab kom nws luam tawm kom pom tseeb. Qhov no tshwm sim vim nws muaj tib lub pixels tab sis nyob rau hauv ib cheeb tsam me.
Vector cov khoom yog txhais los ntawm kev sib npaug ntawm lej, hu ua Bezier Curves, tsis yog pixels. Hloov cov cwj pwm ntawm cov khoom vector tsis cuam tshuam rau qhov khoom nws tus kheej. Koj tuaj yeem hloov pauv txhua tus lej ntawm cov khoom ntiag tug yam tsis tau rhuav tshem cov khoom yooj yim. Ib yam khoom tuaj yeem hloov kho los ntawm kev hloov nws cov cwj pwm thiab los ntawm kev tsim thiab hloov nws siv cov nodes thiab tswj tuav.
Fonts yog ib hom vector khoom. Koj tuaj yeem pom ib qho piv txwv ntawm cov ntaub ntawv tom qab daim duab vector hauv qhov kev piav qhia ntawm cov ntaub ntawv SVG.
Vim tias lawv tuaj yeem hloov tau, cov duab vector-raws li kev daws teeb meem ywj pheej. Koj tuaj yeem nce thiab txo qhov loj ntawm cov duab vector mus rau ib qho twg, thiab cov kab yuav nyob twj ywm thiab ntse, ob qho tib si ntawm lub vijtsam thiab luam tawm.
Thaum koj hloov cov duab vector rau bitmap, koj tuaj yeem hais qhia qhov kev daws teeb meem ntawm qhov kawg bitmap rau qhov loj npaum li cas koj xav tau. Nws yog ib qho tseem ceeb kom txuag tau ib daim ntawv theej ntawm tus thawj vector artwork hauv nws thawj hom ua ntej hloov nws mus rau ib qho bitmap. Thaum nws tau hloov dua siab tshiab rau ib daim duab me me, cov duab poob tag nrho cov zoo nws muaj nyob rau hauv nws vector xeev.
Qhov laj thawj tshaj plaws los hloov ib lub vector rau ib daim duab yuav yog siv rau hauv lub vev xaib. Feem ntau thiab lees txais hom ntawv rau cov duab vector hauv lub vev xaib yog Scalable Vector Graphics (SVG).
Vim qhov xwm txheej ntawm cov duab vector, lawv tau zoo tshaj plaws hloov mus rau GIF lossis-p.webp
Cov Khoom Muag Kawg: Cartoons vs. Duab
- Ua los ntawm cov khoom muaj xim.
- Yuav ua tau yam twg.
- ntes cov ntsiab lus ntau dua vim suav pixels siab.
- Tshwj xeeb rau ib qho square lossis duab plaub.
Vector cov duab txuas ntxiv mus ntxiv. Niaj hnub no cov cuab yeej vector siv bitmapped textures rau cov khoom, muab lawv cov duab tiag tiag. Cov cuab yeej no kuj tsim cov kev sib xyaw mos, pob tshab, thiab shading uas ib zaug nyuaj rau kev ua tiav hauv cov phiaj xwm kos duab vector.
Lwm qhov zoo ntawm cov duab vector yog tias lawv tsis txwv rau cov duab plaub zoo li bitmaps. Vector cov khoom tuaj yeem muab tso rau ntawm lwm yam khoom, thiab cov khoom hauv qab no yuav pom los ntawm. Ib lub voj voog vector thiab lub voj voog bitmap zoo li qub thaum pom nyob rau tom qab dawb. Txawm li cas los xij, thaum lub voj voog me me tau muab tso rau lwm cov xim, nws muaj lub thawv duab plaub nyob ib puag ncig nws los ntawm cov pixels dawb hauv daim duab.
Kev Txiav Txim Kawg
Vector dluab muaj ntau yam zoo, tab sis lub ntsiab tsis zoo yog tias lawv tsis tsim nyog rau kev tsim cov duab tiag tiag. Vector dluab feem ntau muaj cov xim ntawm cov xim lossis cov xim gradients, tab sis tsis tuaj yeem piav qhia txog cov suab nrov tsis tu ncua ntawm daim duab. Tias yog vim li cas feem ntau cov duab vector yuav muaj qhov zoo li tas luav.
Vector cov duab feem ntau yog los ntawm software. Koj tsis tuaj yeem luam theej duab ib daim duab thiab txuag nws ua cov ntaub ntawv vector yam tsis siv software hloov pauv tshwj xeeb. Ntawm qhov tod tes, cov duab vector tau yooj yim hloov mus rau bitmap. Cov txheej txheem no hu ua rasterizing.
