Isithombe sedijithali siqukethe i- ukumelwa oku-ntathu yesithombe esuselwa kumatrix enomboro, okuvamise ukuba kanambambili, ngawo kanye noziro.
Izinqumo zesithombe esidijithali zingaba inamandla noma i-static futhi ngokuya ngalo mgomo bahlukaniswe kabili:
Izinhlobo zezithombe zedijithali
Ama-rasters edijithali noma izithombe ze-bitmaps
Iphikseli ngayinye eyakha isithombe inombala othile futhi ukulungiswa okungaphezulu noma amaphikseli amaningi anayo, ikhwalithi yesithombe izoba ngcono.
Enye yezinhlelo ezisetshenziswa kakhulu ukuhlela izithombe yaziwa kakhulu Izithombehop, imiphumela yayo mihle kakhulu, noma kunjalo, izithombe ze-rasters lapho zikhulisiwe zilahlekelwa ubukhali, ngoba izinhlelo zokuhlela zingena esikhundleni samaphikseli kwabanye okungekhona okwangempela.
Lolu hlobo lwezithombe zedijithali luvame ukusetshenziswa ku amawebhusayithi wezithombe, ezithombeni nakweminye imifanekiso yedijithali ngoba ikhwalithi nemininingwane ayinikezayo ibalulekile.
Izithombe zeVector
Ngokuphikisana ne- izithombe ze-digital rasters, awakhiwe ngamaphikseli, kodwa kunalokho shiya ihluzo zevector okuncike kumaphoyinti athile wokulawula, ngenxa yokuqukethwe kwabo kwamafomula wezibalo bayakwazi ukwakha ama-curvature phakathi kwephoyinti elinye nelinye futhi lapho uhlelo lokuhlela lusetshenziswa, kumane kubala ifomula bese kuguqulela isithombe kuzidingo zomsebenzisi.
Izithombe zeVector asetshenziselwa ukukhiqizwa kwezithombe ezilula, njengamalogo, izikhala zemigqa, imifula, amamajini nezinye izingoma ezingezona eziyinkimbinkimbi ze-typographic. Izinhlelo ezisetshenziswa kakhulu ukudala nokuguqula ihluzo nazo Umdwebo we-Corel y I-Adobe Illustrator.
Yiziphi izindlela zombala?
Isithombe sedijithali singaba ne- inqwaba yemibala noma cha, lokhu kuzoya ngohlobo lomsebenzi ocacile owufunayo.
Kunezindlela eziningana zombala, okugqame kakhulu i-RGB ne-CMYK futhi lezi ngezinye zezinto ezibaluleke kakhulu futhi ezisetshenziswe ezithombeni zedijithali:
Imodi ye-Monochrome
Iyaziwa ngoba izithombe zimnyama futhi zimhlophe kuphela.
Imodi yokumpunga
Kusetshenziswa kuze kufike kuma-250 shades amnyama, amhlophe nampunga.
Imodi yombala ekhonjisiwe
Kufika imibala engama-256 etholakala kufayela elilodwa elicishe libe ngama-bits ayi-8.
Imodi ye-HSB
Kulokhu kukhona ifayela le- Iphalethi yombala wokuqukethwe 25-bit futhi umbala ngamunye unombala wawo, ukugqama, nokugcwala kwawo.
Imodi ye-RGB
Le yiyona esetshenziswa kuma-PC nezikrini zeselula, kunjalo ingxenye yemibala eyisisekelo emi-3, njengoba kubomvu, kuluhlaza okwesibhakabhaka nokuhlaza okwesibhakabhaka futhi kusuka kulezi kungenzeka ukumela noma yimuphi omunye umbala.
Imodi ye-CMYK
Kuvela ku Ukuxubana kombala weCyan, Magenta, Ophuzi noMnyama, kufinyelela kuphela imibala etholakala kububanzi obubonakalayo futhi obusetshenziswa ikakhulu kulezo zithombe ezidinga ukuphrintwa okulandelayo ukuvimbela imibala ekushintsheni nayo.
Kubalulekile ukukhumbula lokho izinhlelo ezinjenge-Photoshop Bavumela ukuthi kwenziwe izinguquko ezithombeni ezingaba wusizo olukhulu lapho kuguqulwa izithombe zombili izikrini nokuphrinta.
Izinhlobo zokucindezelwa kwesithombe sedijithali
Lokhu kucindezelwa kwenziwa ukuze kuncishiswe isikhala esinezithombe ezithile futhi kunezinhlobo ezimbili:
Ukulahlekelwa: ngale nqubo kutholakala cindezela isithombe ngaphandle kokulahlekelwa noma iyiphi into noma ngabe incane kangakanani, ngenzuzo yokuthi isithombe sokuqala singatholwa ngaphandle kwezinkinga
Ilahlekile: umqondo wokusebenzisa le nqubo yokucindezela ngu hlala isikhala esincane ngangokunokwenzeka, yenza isithombe singasindi, kepha ngeshwa lokhu kubangela ukuthi izingxenye zaso zilahleke, yize kwesinye isikhathi lokhu kungabonakali.
Sizokhuluma ngezansi kwezinye izinhlobo zamafomethi wesithombe sedijithali
- Ifomethi ye-JPG / JPEG
- Ifomethi yesandiso sesithombe se-Gif
- Ifomethi yesithombe PNG
- Ifomethi yesandiso sesithombe .tiff / .tif
- Ifomethi yesithombe se-RAW
- Ifomethi yesithombe BMP
- Ifomethi yesandiso sefayela lesithombe .psd
Amanye alawa mafomethi vumela ukucindezela izithombe noma ngaphandle kokulahleka futhi basebenzela ama-rasters nezithombe ze-vector.
