Pakati pezana remakore rapfuura, nokuda kudiwa munhu kutarisana kumiririrwa data, kutanga kubuda Coding mashoko kwakajeka. Nhasi, isu kare hatigoni kufungidzira kombiyuta pasina dzakazara makuru vaima sikirini. Modern sefa uye kombiyuta monitors zvakasiyana chaizvo kubva ayo vamutangira: mufananidzo zvakawanda zvinonakidza uye sezvazviri, yakadzika uye vapfumi mavara - mberi zvinooneka. Saka, pane ari Coding mashoko kwakajeka? Sezvo chifananidzo unoratidzwa pamadziro? Kuti tinzwisise izvi, zvinokosha kuti tiongorore musimboti unoponesa Data kupinda digitaalinen Manyorerwo uye kwavakazoita kurega.
Sezvatinoziva, kuti Coding mashoko - iri chaizvo nguva yakawanda asi zvakakodzera muitiro, sezvo kombiyuta chete inoshanda pamwe muchina Codes. Video, chinyorwa, mifananidzo - zvose zviri digital pamanyorerwo iri dzikwanise mubatanidzwa Kwemagandanga Achishandisa Kombiyuta. Sei Coding mashoko kwakajeka?
Kana kutarira tarisisa ane zvakapetwa kagumi kuwedzera, tinogona kuona kuti inoitwa mumwe muzvizhinji masero rectangular kana dzeraundi, dzikarongwa muna matatu, anonzi pixels. Zvakaratidza kuti mufananidzo chidzitiro haasi chimwe chidimbu, zvinonzi ipazwe nezvimedu zhinji duku, vakaronga mumitsara. chifananidzo kwakadaro anonzi bitmap. Pixels mamwe mavara: tsvuku, girini uye zvitema (RGB-urongwa). Other Mavara anobudiswa kana yakavhenganiswa. A Pixel inogona kana abatidza kana kwete (1 kana 0). Uyezve, imwe Hue dzingasiyana zvichienderana luminescence kuchinyanya ichi vachiri mberi dzinounzwa matomu. Kuwanda kwemashoko dzinounzwa rimwe Pixel, anonzi ruvara udzamu (k). Kubva ukoshi ichi zvinoenderana nokuwanda mavara kuti zvinogona kuratidzwa pamusoro chidzitiro (n). Pane nzira kuti tsanangudzo yacho: n = 2K. Zvikurukuru, mashoko hwakajeka anomirirwa muna 8, 16, 24 kana 32-yati shanduro, zvichienderana PC Hardware namano.
Modern LCD sefa vanokwanisa kuridza anopfuura mabhiriyoni 4 mavara. Enzanisa vamwe matatu kana mana apfuura, mumwe kombiyuta aiva palette 16 mavara!
The mufananidzo unhu pamadziro hakubvi chete pamusoro nhamba mavara vakaratidza, uye chidzitiro kwemupfungwa, asi pamusoro mufananidzo nemashoko rokuti "DPI" - kuwanda pixels muzana chikwata nharaunda. The maduku ukoshi ichi, kuti "grainy" kuwana mufananidzo.
Coding mashoko hwakajeka inokupai iwe kutendeutsa chifananidzo kuva vector format. Vector mufananidzo - nzira yokumiririra zvinhu vachishandisa nyore geometric zvitarisiko: pfungwa, mitsetse, makakombama, polyhedra. nzvimbo yavo chidzitiro chinorondedzerwa nenzira Coordonatele, ruvara kunogonawo kugadziridzwa, uye pakukora yacho unhani mitsetse. Nemhaka mamiriro ayo, ndangariro zhinji akagadzirirwa kushanda bitmaps, saka Graphics vari Vector amiririrwe, kazhinji pachine, pamberi vanoratidza chinogadzirwa ne panorongwa.
mashoko kwakajeka Binary Coding murugwaro muchimiro chakaitwa nenzira sezvo vhidhiyo yeEncoding uye mufananidzo.
