Yuav ua li cas yog vector graphics editor

Rau cov ua ntawm cov dluab thiab tsim drawings rau computer siv raster thiab vector processors, uas yog cov sib txawv encoding qauv (hom) thiab tus sawv cev ntawm graphical ntaub ntawv.

Raster graphics editors

Editors siv dot (pixel) sawv cev ntawm cov duab, qhov no yog vim li cas yog hu ua raster (bitmepovymi, me ntsis), thiab lawv yog npaj rau cov zauv cov duab los yog luam dluab.

Bitmaps no yeej tseem zoo ib matrix los yog daim phiaj, feem ntau lub xim cov ntsiab lus (pixels) nyob rau hauv cov ntxaij vab tshaus ntawm tus saib thiab zaub pab kiag li lawm los yog rau ntawm daim ntawv. Lub ntsiab yam ntxwv ntawm cov dluab yog qhov luaj li cas, nyob rau hauv pixels, me ntsis tob (lub ntsis tob dluab) xim qauv / qhov chaw (CMYK, RGB, YCbCr, XYZ thiab al.) Thiab cov kev daws teeb meem (tus xov tooj ntawm daim duab cov ntsiab lus ib chav tsev cheeb tsam los yog ntev).

Ib tug classic piv txwv ntawm ib tug bitmap editor, ntawm chav kawm, yog unmatched (tsis tau) Photoshop kev pab cuam thiab "laus" los ntawm Microsoft - Xim Editor.

Vector graphics editors

Yuav kom tsim complex drawings nrog leej, complex thiab meej thaj tsam no mas siv vector graphics editor, ib tug ntawm lub ntsiab seev uas yog Bezier curves, uas kos curves (tawg kab, ncaj thiab tus) ya nrog leej nkag rau ntawm lub node (yug) cov ntsiab lus, thiab tswj tus duab ntawm txhua ya.

Bezier nkhaus yuav tuaj raws li qhov tshwm sim ntawm Translational nthuav dav polygon zoo, kab zoo defining ib series kev twb kev txuas ntawm cov tswj cov ntsiab lus. Nkhaus, tsiv los ntawm lub starting taw tes rau ntawm lub polygon rau nws kawg taw tes, yog twv raws li ib tug hlau nplaum, rau intermediates defining daim ntawv pab txhawb nqa cov ntsiab lus, los ntawm kev uas nws tus kheej tsis tau.

Vim nws tshwj xeeb, lub simplicity ntawm neeg ua hauj lwm thiab tau muab Bezier curves yog lug siv rau cov qauv du curves nyob rau hauv computer graphics.

Lub arsenal ntawm cov cuab yeej nyob rau ntawm txhua vector graphics, yeej ib txwm tam sim no, "Sau", "nyeem", "mem hluav" thiab ib tug yooj yim txheej ntawm geometric duab (piv txwv li. N. Lub primitives), uas tas lub hauv paus ntawm feem ntau nraaj designs.

Pouring, raws li nyob rau hauv lub bitmap editors, tsuas txwv chaw qhia kom meej cov xim (los yog gradient).

Yuav kom ua tau ib lub uas tsim nyog ntawv nyeem cuab tam yog ces hloov dua siab tshiab rau curves los xyuas kom meej lub ywj pheej ntawm daim duab mus tsim lub fonts uas muaj (los yog tsis muaj) nyob rau hauv siv computer rau saib.

Mem hluav rau manually kom muaj ib tug kab nrog ib tug loj tus naj npawb ntawm nodal cov ntsiab lus, uas yog ces muab tshem tawm los ntawm txhais tau tias ntawm ib tug tshwj xeeb muaj nuj nqi uas tswj nkhaus.

Txawj thiab kev qaug zog ntawm vector graphics

Dluab uas tso cai rau koj los mus tsim vector graphics editor, muaj ib tug xov tooj ntawm cov teeb meem loj zoo dua raster dluab, cov tseem ceeb tshaj plaws uas yog cov nram no:

• nce los yog yuav txo tau nyob rau hauv vector kos duab kiag li tsis cuam tshuam rau clarity ntawm ib thaj tsam thiab nkhaus;
• vector duab cov ntaub ntawv luj tsawg, ceteris paribus;
• Vector dluab tsis nyuab raster khoom, ntiav ib tug me me volume ntawm lub computer nco tshaj zoo xws li cov bitmaps;
• Vector dluab yog scaled thiab hloov tsis poob zoo, raws li lawv yog ua los ntawm kev kawm txog lej qhia txog ntawm cov khoom, cov kab thiab cov voj voog;
• tej vector editor tso cai rau kom kho neeg lub Cheebtsam ntawm tus qauv uas tshwm rov rau lwm yam hais txog cov duab, yog li nqus khoom tej zaum yuav sib tshooj tsis muaj cov teeb liab ntsais nrog txhua lwm yam;
• nyob rau hauv tej yam mob thiab nyob rau hauv tej yam tej yam kev mob nws tseem tau mus hloov raster dluab rau hauv vector.

Nrog kev xav txog cov raug ntawm cov vector sawv cev ntawm lub duab ntxiv, qhov tseem ceeb ntawm lawv muaj feem xyuam rau "candor" lub ntsiab Cheebtsam ntawm vector graphics, thiab qhov, raws li peb paub, tsis txhob ncaj nraim kab. Yog li ntawd, ib tug vector editor "tsis kam txiav txim" los tsim ib tug zoo nkauj, muaj tiag paintings.

Zoo thiab tsis zoo ntawm cov bitmap dluab

Lub ntsiab zoo ntawm raster editors yog simplicity thiab muaj peev xwm mus tsim kev yees duab-muaj tiag dluab, txij li thaum, ua tsaug rau lub matrix ntsiab cai ntawm constructing dluab, txhua pixel yuav muab tej yam hauv lub tsheej lab ntawm ntxoov.

Lub ntsiab disadvantages ntawm bitmap graphics yog xam tau tias yog kev txwv ntawm scalability thiab transformation tsis poob zoo, raws li zoo raws li lub kuj loj luj ntawm cov ntaub ntawv rau lawv ntau dependence rau cov duab zoo.

Saib xyuas thiab sib piv ntawm cov vector editors

Niaj hnub no, designers, nyuab thiab zoo tib yam cov neeg siv yuav tsis yws yws txog cov tsis muaj software kev pab kom paub lawv tej tswv yim thiab refinements. Qhov no kuj siv rau vector editors, lub ntsiab txheej xwm ntawm nqis uas rau ib co yog cov functionality, tab sis rau lwm tus - cov nyob rau ntawm (them / dawb).

Ntawm cov dawb cov kev pab cuam Feem ntau cov uas muaj tuaj Dia, OpenOffice.org Kos, sK1 (diav rawg Skencil), Inkscape, Xara Xtreme rau Linux, Skencil (ex-Sketch), Sodipodi, qhia tsim, Pivot Stickfigure Animator, thiab Alchemy.

Ntawm no, tsuas yog nyob rau Linux sau editor vector sK1 (diav rawg Skencil), nyob rau Linux thiab OS X kev khiav hauj lwm Xara Xtreme kev pab cuam thiab Skencil, editors tsim rau lub qhov rais qhia Design thiab Pivot Stickfigure Animator, thiab txhua leej txhua tus lwm tus - tus ntoo khaub lig-platform.

Cov feem nrov thiab haumxeeb "txias" qhov kev pab cuam, ntawm chav kawm, them nyiaj. Daim ntawv muaj xws li cov neeg kho tsev av Flash, Tsev av tuav, Tsev av Freehand (Qhov rai, OS X), thiab CorelDRAW thiab Xara Designer PRO (Qhov rai).

Uas nyob rau hauv lub ntiaj teb tag nrho cov sweeter

Yog hais tias vector editors nug hauv daim iav ntawm "uas nyob rau hauv lub ntiaj teb tag nrho cov sweeter," nws yog tau hais tias, teb hais tias: "Koj zoo nkauj heev, tsis muaj tsis ntseeg," rau hauv daim iav yuav ntxiv: "tab sis Coreldraw vector editor ntawm tag nrho cov sweeter ...". Xijpeem, ib tug zoo ib nrab ntawm cov neeg siv, nrog rau cov tub txawg, yuav pom zoo nrog cov uas.

Coreldraw duab editor muaj nyob rau hauv lub pob, uas yog lub 10 version ntawm lub npe Coreldraw Graphics Suite. Coreldraw Nyob rau hauv tas li ntawd, qhov no pob muaj xws li ib tug graphical editor Corel Diam duab-Xim (bitmap), qhov kev pab cuam yog transforming raster dluab rau hauv vector hom Corel txoj lw, animator Corel Rav E thiab Corel Cupture mus rau cov hloov cov dluab ntawm lub computer ncaj qha mus rau ib cov ntaub ntawv los yog mus rau ntawv los teev cia lub qhov rais.

Nrov hwjchim ci ntsa iab Coreldraw editor yog yuam ua hauj lwm tsis tsuas mus rau nws zoo kawg li functionality, tab sis kuj yog ib tug lossis loj cov tsev qiv ntawv ntawm ready-made dluab, thiab ua-nyob rau hauv software ib tug haib system ntawm kev cob qhia thiab cov tswv yim. Nyob rau hauv tas li ntawd, lub editor muaj cov txhais tau tias tsis muaj analogues nyob rau hauv lub "lug txhawb cov miv".
