Raster mifananidzo uye basa navo

Kana kushanda maviri-dimensional Graphics, zvakakosha chaizvo kunzwisisa zvinokosha ayo mamiriro uye nenheyo zvinofanira kushandurwa pamusoro izvo zvichaita, mune shoko, kumiririra, sezvinoonekwa ne kombiyuta. Vaviri Mhando chikuru mifananidzo - vector uye Raster -each anowana kushanda kwayo pane imwe nzvimbo, uye anewo ayo zvakanakira.

Vamapoka iyo bitmaps vari pixels. Ava zvidiki dzinoungana vanhu tarisisa, izvo itakurwe nekufambisa ruvara ruzivo. Avo rubatsiro bitmaps akapeta akafanana dambanemazwi, uye anonzwisiswa yose. Quality tarisisa kuratidza mifananidzo izvi zvinoenderana nokuwanda pixels por padiki. Kumboda makombiyuta zvose ano anogadzirwa pamwe chisarudzo 72 kana 96 pixels por padiki (kukosha dzinosiyana-siyana zvichienderana parameters chidzitiro).

Raster Mifananidzo inogona kukurumidza kusiyaniswa kubva Vector nokutarira pakukura kwavo. Rakajairika zvinogona kuti Raster - a .gif, .bmp, .png, .jpeg, .psd uye nevamwe.

Raster mifananidzo vari vakawana paakasika faira muna Adobe Photoshop vachishandisa zvinhu zvokushandisa, uyewo kushanda pakuvheneka atawana. Uyezve, mapikicha zvose ndezvaJehovha ichi mhando mbiri-dimensional Graphics. Saka, pasina kuchinja pamanyorerwo kwemarudzi aya mafaira pakuitika, unogona kudzivisa unhu kufirwa uye kukanganisa mavara. Uye kupirinda mifananidzo muchishandisa, aidhinda ave bitmap mufananidzo.

Translation Raster mufananidzo kuva Vector iri zvakaenzanirana nyore uye chete kunoda Graphics mupepeti hunotsigira zvose marudzi zvifananidzo. Muchiitiko chino, kana iwe kunze mufananidzo kungotaura kunoratidza Vector Graphics format. Zvisinei, nzira iyi hapasi kupa migumisiro yakanaka. Zviri zvikuru kuti manually redraw ari bitmap mufananidzo kuva Vector, asi zvinoda unyanzvi zvakanaka kushanda Vector Graphics mupepeti.

Saka, ngatirambei zvinosimbisa pfungwa huru dzehurukuro yacho bitmap mufananidzo pamusoro chidzitiro - a Pixel afoot, unhu iyo kunobva chisarudzo chako Monitor. Graphics kwakadaro kunogona nyore mudzoke kunyika imwe format. Pamusoro kunyatsoongorora nematunhu aya ari muchimiro mifananidzo polyline edzinza zvikamu inova miganhu pixels.

Raster mifananidzo vari, hapana mubvunzo, zvainovhiringidzawo dzavo uye zvausingakwanisi, idzo hazvigoni kungotariswa. Kusiyana Vector Graphics, mifananidzo yakadaro vane miganhu kuwedzera uye dzimwe kuchinja zvikuru. With kuwedzera neshekeri rimwe bitmap, zvingangoita kuti kurasikirwa nemari. Naizvozvo, kuchengetera ari Pixel mifananidzo guru saizi anofukidza ukuwo, uye yakawanda ndangariro kombiyuta. Mukuwedzera, Raster Graphics rinenge haritsigiri pachena ehupfumi. mifananidzo chete .gif uye .png rusununguko urwu dzinoti, uye saka vane unhu wakakwirira chechetere.

Raster nemanyorerwo chinonyanya akakodzera vaya vari nyasha rakasikwa mifananidzo pamwe kunzwisisa sezvazviri mumvuri, uye vamwe-dimensional matatu zvinokonzerwa uye textures. Uye, chokwadi, Photographers avo dzinoona zvifananidzo zvenyu Photoshop, unoratidza chete bitmap mhando kwakajeka.
