Mufananidzo wedhijitari une maviri-mativi ekumiririra yemufananidzo wakatarwa nemamrix matrix, ayo anowanzoitwa binary, neayo uye zero.
Sarudzo dzemufananidzo wedhijitari dzinogona kuve zvine simba kana zvamira uye zvichibva pane ichi chirevo ivo vakapatsanurwa kuita mbiri:
Mhando dzemifananidzo yedhijitari
Rasters digital mifananidzo kana bitmaps
Pikisi yega yega inogadzira iyo mufananidzo ine imwe yakatarwa uye resolution yepamusoro kana mamwe mapikisheni avanayo, zvirinani hunhu hwemufananidzo huchave.
Imwe yemapurogiramu anonyanya kushandiswa kugadzirisa mifananidzo ndiyo inozivikanwa photoshop, avo mhedzisiro yakanaka kwazvo, zvisinei, mifananidzo ye raster kana yawedzeredzwa inorasikirwa nekupinza, kubvira zvirongwa zvekugadzirisa zvinotsiva pixels kune zvimwe zvisiri zvechokwadi.
Mhando iyi yemifananidzo yedhijitari inowanzo shandiswa mu graphic mawebhusaiti, mumifananidzo uye mimwe mifananidzo yedhijitari sezvo hunhu uye zvakadzama zvavanopa zvakakosha.
Vector mifananidzo
Kupesana ne digital rasters mifananidzo, haana kunyorwa nemapikiseli, asi ibva vector mifananidzo zvinoenderana nezvimwe zvinongedzo, nekutenda kune kwavo kwemasvomhu mafomula anokwanisa kugadzira makenduru pakati peimwe poindi neimwe uye kana chirongwa chekugadzirisa chikaiswa, inongoverenga fomura uye inochinjisa iyo mufananidzo kune zvinodiwa nemushandisi.
Vector mifananidzo zvinoshandiswa kugadzirwa kwemifananidzo yakapusa, senge marogo, kusiyanisa mitsara, nzizi, margins uye zvimwe zvisina kuomarara typographic nziyo. Iwo mapurogiramu akanyanya kushandiswa kugadzira uye kugadzirisa maficha ari zvakare Corel Dhiza y Adobe Illustrator.
Ndeapi mavara emhando?
Mufananidzo wedhijitari unogona kuva ne boka remavara kana kwete, izvi zvinoenderana nerudzi rwe graphic basa raunoda.
Kune akati wandei mamodheru emhando, akanyanya kuzivikanwa ari RGB uye CMYK uye aya ndiwo mamwe akakosha uye anoshandiswa mumifananidzo yedhijitari:
Monochrome maitiro
Iyo inozivikanwa nekuti mifananidzo yacho nhema uye chena chete.
Grayscale mode
Kusvikira mazana maviri nemakumi mashanu emvuri nhema, chena uye grey zvinoshandiswa.
Yakarongedzwa color mode
Kusvikira pamakumi maviri nemaviri emavara anowanikwa mune imwechete faira ingangoita gumi nemasere.
HSB maitiro
Kune izvi pane inogutsa ruvara pendi 25-bit uye yega yega ruvara iine yayo hue, kupenya, uye kuzadza.
RGB modhi
Iyi ndiyo inoshandiswa muPC uye nharembozha, iri chikamu chemavara matatu ekutanga, sezvakaita tsvuku, girini uye bhuruu uye kubva pane izvi zvinokwanisika kumiririra chero rimwewo ruvara.
CMYK maitiro
Inomuka kubva ku Cyan, Magenta, Yero uye Nhema kusanganisa kwemavara, ichizadzikisa chete mavara ari mune iyo spectrum inoonekwa uye inoshandiswa zvakanyanya mune iyo mifananidzo inoda kuprindwa kunotevera kudzivirira mavara kubva kuchinjika nayo.
Izvo zvakakosha kuti urangarira izvo zvirongwa zvakaita sePhotohop Vanokutendera iwe kuti uite shanduko kumifananidzo iyo inogona kubatsira zvakanyanya kana uchigadzirisa mifananidzo yezvose zvidzitiro uye anodhinda.
Mhando dze digital image compression
Kudzvanywa uku kunoitwa kuitira kudzikisira nzvimbo inogara mimwe mifananidzo uye kune mhando mbiri:
Pasina kurasikirwa: kuburikidza nemaitiro aya zvinoitika dzvanya mufananidzo pasina kurasikirwa nechero chinhu, kunyangwe chiri chidiki sei, zvine mukana wekuti gare gare mufananidzo wekutanga unogona kutorwa pasina matambudziko
Kurasika: pfungwa yekushandisa iyi compression maitiro ndeye kutora nzvimbo diki sezvinobvira, ita kuti mufananidzo wacho usanyanya kurema, asi izvi zvinosuwisa zvinoita kuti zvikamu zvacho zvirasike, kunyangwe dzimwe nguva izvi zvisingaonekwe.
Tichataura pazasi mamwe emhando dzerasta yedhijitari emifananidzo mafomati
- JPG / JPEG fomati
- Gif yekuwedzera mufananidzo fomati
- Mufananidzo fomati PNG
- Mufananidzo wekuwedzera fomati .tiff / .tif
- RAW mufananidzo fomati
