Chii vector Graphics mupepeti

Nokuti kugadzira zvifananidzo uye nokusika vanodhirowa pakushandisa kombiyuta Raster uye Vector processors, izvo zvakasiyana yeEncoding nzira (youduku) uye mufananidzo pamusoro graphical mashoko.

Raster Graphics vapepeti

Vapepeti kushandisa dot (Pixel) cherudo mufananidzo, nokuti chikonzero ichi inonzi Raster (bitmepovymi, ikakuruma), uye vari aiendeswa processing digitaalinen mifananidzo kana tarisa mifananidzo.

Bitmaps vanotova munhu chizvaro kana afoot, kazhinji rectangular ruvara pfungwa (pixels) pamusoro sefa pamusoro monitors uye kuratidza mano kana papepa. The chikuru maitiro mifananidzo izvi ndiyo saizi, muna pixels, ikakuruma udzamu (Judhasi udzamu mifananidzo) ruvara womuenzaniso / nzvimbo (CMYK, RGB, YCbCr, xyz and unto.) Uye chisarudzo (nhamba mufananidzo pfungwa por chikwata nzvimbo kana urefu).

A klassiske muenzaniso bitmap mupepeti Chokwadi, ndizvo unmatched (asi) Photoshop chirongwa uye "mukuru" kubva Microsoft - Paint Editor.

Vector Graphics vapepeti

Kusika kunzwisisa vanodhirowa pamwe chaiwo, kunzwisisa uye yakajeka pokugumira Anonyanyowanika kushandiswa Vector Graphics mupepeti, mumwe mukuru zviridzwa zviri Bezier makakombama, vachibvumira kuswedera makakombama (kuputswa mitsetse, yakananga uye kumeso) chidimbu chete chairo placement yacho raiva pedyo nebundu (rutsigiro) pfungwa, uye kudzora chimiro mumwe chidimbu.

Bezier munyonga inogona achimiririrwa mugumisiro translational yksityiskohta polygon chimiro, mutsetse chimiro kutsanangura dzakatevedzana kubatana kudzora pfungwa. Munyonga, kutamira kubva pokutangira ari polygon wacho magumo pfungwa, achikwevewa sezvo magineti, kuti intermediates zvaraireva chimiro rutsigiro pfungwa, iyo pachayo asingadi kupfuura.

Nokuda kwayo chaiyo ehupfumi, ari nyore basa uye mukana chokushandisa Bezier makakombama anoshandiswa nevakawanda kuti zvinoedza makakombama kumeso mu kombiyuta Graphics.

The zvombo zvekushandisa dzaidzidziswa mumwe Vector Graphics, vanogara varipo, "Kuzadza", "chinyorwa", "penzura" uye inokosha akagadzirwa geometric zvitarisiko (kureva. N. The primitives), izvo anoumba hwaro vakawanda kwakajeka mazano.

Kudururwa, sapamazuva bitmap vapepeti, echitema shoma nzvimbo kutaridzwa ruvara (kana gradient).

Kusika yakakodzera chinyorwa chokushandisa ari ipapo kutendeukira makakombama kuitira rusununguko chifananidzo zvokusika fonts dziripo (kana kwete kuwanikwa) pamusoro kushandiswa kombiyuta kuona.

Penzura manually vaunze tambo vakawanda nodal pfungwa, ayo akabva abvisa achishandisa basa rinokosha kuti hwezvekukurukurirana munyonga.

Uye yakaipirei vector Graphics

Images unokubvumira kusika Vector Graphics mupepeti, vane zvinoverengeka zvinokosha zvakanakira pamusoro Raster mifananidzo, chinonyanya kukosha izvo zvinotevera:

• kuwedzera kana kudzikisa Vector vanodhirowa zvachose asingadi kukanganisa Kujeka miganhu uye contours;
• Vector mufananidzo mafaira kuyera zvishoma, ceteris paribus;
• Vector mifananidzo pasina kuoma Raster zvinhu, anoshandisa bhuku diki kombiyuta ndangariro pane zvakafanana bitmaps;
• Vector mifananidzo vari scaled uye wakashandurwa pasina kurasikirwa quality, sezvo ivo yakavakwa kwemasvomhu kurondedzerwa zvinhu, mitsetse uye madenderedzwa;
• chero Vector mupepeti kunoita kuti kuchinja mumwe zvinoumba nomufananidzo pasina kukanganisa vamwe zvinhu chifananidzo, saka richiswedera zvinhu anogona bindepinde pasina kuvhiringidza mumwe;
• mune zvimwe zviitiko uye pasi zvimwe zvirwere zvinoita kutendeutsa Raster mifananidzo kupinda vector.

Panyaya pokuperevedza ari Vector kumiririrwa mashoko akajeka, chinonyanya kukosha kwavari chokuita "kutendeseka" huru zvinoumba Vector Graphics, uye hunhu, sezvo tichiziva, kudzivisa kururamisa pemitsara. Naizvozvo, munhu Vector mupepeti "aramba kutora mirairo" kuumba yakanaka, chaizvoizvo mifananidzo.

Zvakanakira nekuipira bitmap mifananidzo

The chikuru zvakanakira Raster vapepeti vari nyore uye Kugona Photo-chaizvoizvo mifananidzo, sezvo, nemhaka chizvaro nheyo kuveza mifananidzo, mumwe Pixel anogona kupiwa chero mamiriyoni maketeni.

The chikuru zvazvakashatira bitmap Graphics vanoonekwa nezvezvisingakwaniswi scalability uye kuchinja pasina kurasikirwa yepamusoro, uyewo pfupi guru kurema mafaira dzavo kunyanya kuvimba mufananidzo unhu.

Review uye kuenzanisa vector vapepeti

Nhasi, vagadziri, vemifananidzo uye vanhuwo vanoshandisa havagoni kugunun'una pamusoro kushaya-software mari pakuziva pfungwa dzavo okusika uye kugadziridzwa. Izvi zvinoshandawo Vector vapepeti, chikuru nzira chokuita izvo vamwe ndiro functionality, asi vamwe - Kuwanikwa (akabhadhara / akasununguka).

Pakati vakasununguka mapurogiramu Zvinonyanyozivikanwa anomiririrwa Dia, OpenOffice.org Vhomora, sK1 (forogo Skencil), Inkscape, Xara Xtreme nokuti Linux, Skencil (aimbova-Sketch), Sodipodi, Chiratidzo Design, Pivot Stickfigure Animator, uye Alchemy.

Ava, chete Linux anofambisa mupepeti Vector sK1 (forogo Skencil), musi Linux uye Os X kushanda Xara Xtreme chirongwa uye Skencil, vapepeti rakagadzirirwa Windows Rwekutaura Design uye Pivot Stickfigure Animator, uye vose - muchinjikwa-papuratifomu.

Kupfuura dzakakurumbira uye dzichipfekeka "inotonhorera" purogiramu Chokwadi, akabhadhara. The Pamazita zvinosanganisira vapepeti Adobe Flash, Adobe Illustrator, Adobe FreeHand (Windows, Os X), uye CorelDRAW uye Xara Designer PRO (Windows).

Ndiani panyika yose zvinotapirawo

Kana Vector vapepeti akabvunza girazi kuti "uyo panyika yose atapire," zvinokwanisika kuti, akapindura kuti: "Imi muri Wakanaka, hapana mubvunzo kuti" girazi vangawedzera: "asi Coreldraw Vector mupepeti vose zvinotapirawo ...". Zvisinei, zvakanaka hafu vanoshandisa, kusanganisira nyanzvi, vaizobvumirana kuti.

Coreldraw mupepeti hwakajeka dziri pasuru, unova rechi10 shanduro zita Coreldraw Graphics Suite. Coreldraw Uyezve, pasuru iyi Kunosanganisira graphical mupepeti Corel Photo-Paint (bitmap), chirongwa chiri kuchinja Raster mifananidzo kupinda Vector youduku Corel Trace, animator Corel rav E uye Corel Cupture uchatamisa mifananidzo kubva kombiyuta zvakananga faira kana kuti ari clipboard Windows.

Ruzha kubwinya Coreldraw mupepeti vanosungirwa kwete chete kune zvikuru ake functionality, asiwo guru raibhurari kuti makagadzirira-zvifananidzo, uye akavaka-mu-software kwegadziriro kurovedza uye mazano simba. Mukuwedzera, mupepeti anokwanisa vasina analogues mu "nevamwe".
