I-GIMP inikeza izindlela eziningi zokuguqula izithombe zibe mnyama nokumhlophe. Inketho ngayinye iyahlukahluka ngamaleveli ahlukene okuguquguquka kanye nemiphumela ehlukene futhi. Nazi zonke izindlela ongazisebenzisa ukuguqula izithombe kanye nomehluko phakathi kwazo. Ukukhetha omunye phezu komunye kuyindaba nje yokukhetha ngokwesidingo sakho.
Guqula izithombe zibe mnyama nokumhlophe ku-GIMP
Ake siqale ngokulula kweqembu.
1. Nika amandla imodi ye-grayscale
Ngokuzenzakalelayo, isithombe sizovuleka ngemodi ye-RGB, kodwa ukushintsha imodi ibe greyscale kuzoshintsha ngokuzenzakalelayo isithombe sibe mnyama nokumhlophe. Nge-grayscale, njengoba negama liphakamisa, awunakho ukulawula okwengeziwe phezu kwesithombe ngoba kushintsha uhlelo lombala wesithombe ngokuqondile. Awukwazi ukulawula ukushuba noma iziteshi zombala. Futhi, ayikho inketho yokusetha lokhu kube isendlalelo esisodwa kuphela. Uma isinikwe amandla, izosetshenziswa kuso sonke isithombe kanye nazo zonke izendlalelo.
Ukuze uguqule isithombe sibe mnyama nokumhlophe usebenzisa i-grayscale, chofoza Isithombe > Imodi bese ukhetha Umsakazo Indawo empunga.
Lokhu kuzoguqula isithombe sibe mnyama nokumhlophe ngokushesha.
Uma kukhethwe indawo empunga, konke okokufaka nokuhlela okulandelayo nakho kuzoba kumpunga. Ukushintsha lokhu, futhi, vula Isithombe > Imodi bese ukhetha RGB . Lokhu kuzokhiqiza kabusha imibala ngaphandle kokushintsha isithombe osiguqulele ku-grayscale.
2. Sebenzisa i-desaturation
Ngokungafani nendlela ye-grayscale, nge-desaturation, ungakhetha ukushuba kwesithombe esimnyama nesimhlophe osidingayo. Lokhu kusho ukuthi unenketho yokungaguquleli isithombe sibe mnyama nokumhlophe uma uthanda.
Ukuze uguqule isithombe sibe mnyama nokumhlophe usebenzisa i-Desaturation, khetha isendlalelo ofuna ukusiguqula sibe mnyama nokumhlophe. Futhi unenketho yokukhetha izendlalelo eziningi ngokucindezela inkinobho ye-ctrl.
Uma usukhethiwe, cindezela u-Option umbala kwibha yemenyu bese ukhetha saturation .
Lokhu kuzovula iphophaphu lapho ungashintsha khona ukushuba kwethunzi elimnyama nelimhlophe usebenzisa inketho . Scale .
Leli thuluzi lizolondoloza izinga lokugcwaliswa kwesikhala njengokusetha ngaphambilini okusho ukuthi lizosebenzisa izilungiselelo ezifanayo kwezinye izithombe kamuva. Ngaphandle kwalokho, kunezinye izindlela zokuqeda amandla njenge Ukukhanya, i-Luma, ukukhanya, okumaphakathi و Value . Imodi ngayinye isebenzisa umthunzi ohlukile omnyama nomhlophe esithombeni esingase silungiswe ngokushintsha ukukhanya namashaneli ombala. Ungakwazi ukufinyelela lezi zindlela ngokuvula Imibala> incithakalo bese ukhetha I-Desaturate kwaphinda lokho .
Lokhu kuzovula iphophaphu lapho ungasebenzisa khona lezi zindlela esithombeni.
Esikhundleni sokuthembela ethuluzini ukuze unikeze izindlela ezihlukile ze-grayscale, ungazilungisa mathupha iziteshi ze-RGB ukuze uthole kanye okumnyama nokumhlophe okudingayo.
3. Ukulungiswa nge-Channel Mixer
Ngenketho Yokuhlanganisa Isiteshi, ungenza ngendlela oyifisayo yonke ingxenye yesithombe. Ungakhetha amaleveli abomvu, aluhlaza, naluhlaza okwesibhakabhaka esithombe ukuze uthole umbala ophelele omnyama nomhlophe owufunayo.
Ukuze uguqule imibala ibemnyama nokumhlophe ngesihlanganisi sesiteshi, vula Imibala > Izingxenye > I-Mono Mixer. Lokhu kuzoguqula isithombe sibe mnyama nokumhlophe futhi kuvule iwindi le-popup ukuze wenze ngendlela oyifisayo iziteshi ze-RGB.
Manje ungadlala ngalezi ziteshi ze-RGB ukuze uguqule ithoni yombala wesithombe esimnyama nesimhlophe. Ukugcina izinga elifanayo lokukhanya, kufanele wengeze amanani afika ku-100%. Isibonelo, uma usetha okubomvu kuya kokungu-31%, okuluhlaza kuya kokungu-58%, nokuluhlaza okwesibhakabhaka kube ngu-11%, uzothola isithombe esifanayo esimnyama nesimhlophe njengakunketho ye-grayscale. Ukuze uvimbele le nkinga yokukhanya, ungavumela inkinobho ye-Keep Bright. Izolungisa izendlalelo ze-RGB ngaphandle kokuthinta amaleveli okukhanya.
Nasi isibonelo. Uma ufuna isibhakabhaka esimnyama, yehlisa izinga lesiteshi esiluhlaza okuzokwenza isibhakabhaka sibonakale simnyama. Ungasebenzisa le nqubo ukushintsha imibala yesiteshi ukuze ukhiphe izinto ezithile.
Inzuzo ye-Channel Mixer wukuguquguquka. Kimi, konke kumayelana nokwengeza ukugqama okwengeziwe nokukhipha ukwakheka okuhle nemigqa ezithombeni ngaphandle komsindo okhulayo.
I-Convolution: Guqula izithombe ezimnyama nezimhlophe nge-GIMP
Inketho ye-grayscale yinhle kakhulu ekuguquleni izithombe zibe mnyama nokumhlophe kodwa ayinakho ukulawula okunikezwa ukuqina nezinketho zesiteshi ngenkathi kulungiswa isithombe. Ukunciphisa amaleveli okugcwalisa kusiza ukulungisa ukushuba, kodwa isithombe sokugcina esimnyama nesimhlophe sinomsindo owengeziwe uma siqhathaniswa ne-grayscale kanye lapho usondeziwe. Inketho yokuxuba isiteshi ivumela ukulungisa isithombe ukuze sihambisane nezidingo zakho. Ungakwazi ukulawula umbala ngamunye, futhi ukuze wenze izinto ezifana nokuphendula isibhakabhaka sibe mnyama, noma ukhiphe okuthile okunomthunzi ogqamile, njll.
