Chimiro chema bitmap (kana raster) ndechimwe chezvinhu zviviri zvakakurisa mavara (mamwe ari vector). Bitmap-based images yakagadzirwa nemapikisi mumugero. Pixel imwe neimwe kana "bit" mumufananidzo ine ruzivo pamusoro pemuvara wekuratidzwa. Zviratidzo zveBitmap zvine chisarudzo chakasarudzwa uye hachigoni kugadziriswa pasina kurasikirwa nehuwandu hwemifananidzo. Heino chikonzero nei:
Pixel imwe neimwe iri pahwindo rako, mumashoko akareruka, "bit" yemuvara ruzivo rwakashandiswa kuratidza mufananidzo pachikona. Chirongwa ichocho chinogona kunge chakaita sechinhu pane Apple Watch kana chikuru sePixel Board yakawanikwa muHat Square Square.
Pamwe neavo vanoda kuziva mivara mitatu- Mutsvuku, Green, Blue- yakashandiswa kune pixel imwe "bit" yeruzivo ndiko kuti, chaiyo, iyo pixel iri mumufananidzo.Zviksese izvi zvinoumbwa apo chifananidzo chacho chakabatwa. Nokudaro kana kamera yako inotora mufananidzo pa 1280 pixels kumativi uye 720 pixels pasi pane 921 600 mapikisi emafisi mumufananidzo uye marimi ose emapikisi uye nzvimbo inofanira kuyeukwa uye kushandurwa. Kana iwe ukapeta hukuru hwechifananidzo, zvose zvinoitika ndiyo mapikisikiti anowedzera uye huwandu hwefaira hunowedzera nekuti nhamba imwechete yepiksekisi ikozvino mune imwe nzvimbo huru. Hapana pixisi yakawedzerwa. Kana iwe kuderedza ukuru hwechifananidzo nhamba yakafanana yepikseli iri munzvimbo duku uye, saizvozvowo, faira yefaira inoderedza.
Chimwe chimwe chinokanganisa bitmaps isarudzo. Chigadziro chacho chakanyatsogadziriswa apo mufananidzo wacho wakasikwa. Mazhinji emazuva ano makamera ema digital, somuenzaniso, kutora mifananidzo ne 300 dpi resolution. Zvose izvi zvinoreva kuti pane mazana mapikisi mazana matatu mumasendimita ose emufananidzo wechifananidzo. Izvi zvinotsanangura kuti nei kamera yemamera yekombiyuta inogona kuva yakakura zvikuru. Pane tine mamwe mapikseti kuti ave mapikicha uye ane mavara kupfuura anowanzowanika pamakombiyuta anowanzoonekwa.
Kazhinji bitmap-based formats ndeye JPEG, GIF, TIFF, PNG, PICT, uye BMP. Mifananidzo yakawanda ye bitmap inogona kuchinjwa kune dzimwe bitmap-based formats nyore nyore. Zviratidzo zveBitmap zvinowanzova nezvikuru zvakakura zvefaira kupfuura vector mavara uye zvinowanzomanikidzirwa kuderedza hukuru hwavo. Kunyange zvazvo maitiro akawanda emifananidzo ari bitmap-based, bitmap (BMP) inoratidzikawo maitiro akashandurwa asi kushandiswa kwaro nhasi kunoshamisa.
Kuti udzidze zvakawanda pamusoro pezvinhu zvakasvibirirwa zve bitmaps, tsanangudzo yakazara yepikisi uye kuti inopindira sei mumazuva ano ekufambisa kwemabasa, ungada kuongorora kuti udzidze zvakawanda nezvemafomu akasiyana-siyana emafaira anoshandiswa mukufungidzira iwe ungadawo kuverenga Ipi Ifijhori Yefivha Fomu Yakanakisisa Kushandisa Ipi?
