Hlola isikhala sombala se-software sakho se-HSV isikhala sombala
Noma ubani onomqaphi cishe wezwe ngendawo yombala we- RGB . Uma usebenzisana namaphrinta wezentengiselwano, uyazi mayelana ne- CMYK , futhi kungenzeka ukuthi uphawule i-HSV (Hue, Saturation, Value) kumklami wembala we-software yakho yamahluzo.
Ngokungafani ne-RGB ne-CMYK, echazwe maqondana nemibala eyinhloko, i-HSV ichazwa ngendlela efana nendlela abantu ababona ngayo umbala.
I-HSV ibizwa ngokuthi ibe ngamanani amathathu: i-hue, i-saturation, ne-value.
Lesi sikhala sombala sichaza imibala (i-hue noma i-tint) ngokulandela umthunzi wabo (ukugcwalisa noma inani le-grey) nokubaluleka kokukhanya kwabo.
Qaphela: Abanye abaqoqi bombala (njengaleyo ku-Adobe Photoshop) basebenzisa igama elithi HSB, elifaka igama elithi "Ukukhanya" ngenani, kodwa i-HSV ne-HSB imodeli efanayo yombala.
Indlela yokusebenzisa i-HSV Color Model
Ivili lemibala le-HSV ngezinye izikhathi liboniswa njenge-cone noma isilinda, kodwa njalo ngalezi zici ezintathu:
Hue
I-Hue iyinxenye yombala yemodeli yombala, futhi iboniswa njengenombolo kusuka ku-0 kuya ku-360 degrees:
| Umbala | I-Angle |
| Okubomvu | 0-60 |
| Okuphuzi | 60-120 |
| Okuhlaza | 120-180 |
| I-Cyan | 180-240 |
| Blue | 240-300 |
| I-Magenta | 300-360 |
Ukwaneliseka
Ukwaneliseka kungumuthi ompunga embala, kusuka kumaphesenti angu-0 ukuya kwangu-100. Umphumela ophelile ungaba nokunciphisa ukugcwalisa okubhekene ne-zero ukwethula ngaphezulu kwegrey.
Noma kunjalo, ukufakwa kwe-saturation ngezinye izikhathi kubhekwa ku-range kusuka ku-0-1 kuphela, lapho i-0 igundane khona futhi umbala oyinhloko ngu-1.
Inani (noma ukukhanya)
Inani lisebenza ngokuhlanganyela ne-saturation futhi lichaza ukukhanya noma ukuqina kombala, kusukela kumaphesenti angu-0-100, lapho i-0 ingumnyama ngokuphelele futhi i-100 iyakhanya futhi imbula umbala kakhulu.
Indlela i-HSV isetshenziswa ngayo
Isikhala sombala se-HSV sisetshenziselwa ukukhetha imibala yepende noma iyinki ngoba i-HSV imelela indlela abantu abahambelana ngayo nemibala kunokuba i-RGB isikhala sombala.
Isondo lombala le-HSV lisetshenziselwa ukukhiqiza ihluzo eliphezulu kakhulu. Nakuba engaziwa kangcono kunabakwa-RGB nabakwa-CMYK, indlela ye-HSV itholakala ezinhlelweni eziningi zesofthiwe yokuhlela isithombe esiphezulu.
Ukukhetha umbala we-HSV kuqala ngokukhetha enye yama-hues atholakalayo, okuyindlela abantu abaningi abahlobana ngayo nombala, bese ulungisa umthunzi kanye nenani lokukhanya.
