Wajiyooyin badan oo madow & caddaan ah

Grayscale iyo farshaxanka

Sawirka, Sawirada Black & White waxay dhab ahaantii u egtahay midab. Sawirada dhijitaalka ah ee sawirada B & W waxaa lagu magacaabaa naxwaha si loo kala saaro farshaxanka madaw iyo madow.

Sawirada sawirada sawirada ee Grayscale ee heerarka iftiinka ah sida laga soo xigtay macluumaadka midabka. Sawirada jajabeed ee caadiga ah waa 256 xabbadood oo cawl ah oo ka bilaabma 0 (madow) ilaa 255 (caddaan).

Qeybta Caddaanka ah ee Black iyo White waa caadi ahaan 2-midab (caadi ahaan madow iyo cadaan) farshaxanka, qalin iyo sawir gacmeed, ama sawir gacmeed. Isku-duwidda sawir ilaa farshaxanka (sida lagu arkay sawirada) ayaa laga yaabaa in loo sameeyo waxyeello gaar ah laakiin leh madow ama caddaan kaliya madow, faahfaahinta sawirrada ayaa lumaya.

Marka loo beddelo sawir midab ah B & W, sawirada naxwaha waa goolka.

RGB Sawirrada

Inkasta oo ay suurtagal tahay in lagu sawiro sawir midab ah sawirada ama sawirada sawirada B & W (oo leh kamarado qaar) sidaas darteed marxaladda marxaladda badana, inta badan sawirada aan ku shaqeyno bilawga midabka.

Sawirada midabka iyo sawirada kamaradaha sawir gacmeedka ayaa caadi ahaan qaabka RGB. Haddii aysan ahayn, inta badan waa caado ah in loo badalo RGB oo la shaqeeyo sawirka (wax ka bedelida barnaamijka barnaamijka sawirada) qaabkaas. Sawirada RGB sawirrada qiimaha casaan, cagaaran, iyo buluug, kuwaas oo caadi ahaan samayn doona sawir midab leh. Midab kasta wuxuu ka kooban yahay tiro kala duwan oo ah casaan, cagaaran, iyo buluug.

Mararka qaarkood waa lagama maarmaan ama waa lagama maarmaan in la daabaco ama la muujiyo sawirada Sawirada & Gawaarida (Grayscale). Haddii sawirka asalka ahi yahay midab, barnaamijka barnaamijka sawirada sida Adobe Photoshop ama Corel Photo-Paint ayaa loo isticmaali karaa si loogu badalo muuqaalka midabada nooc ka mid ah madow & caddaan.

Waxaa jira habab badan oo loo heli karo sawirada B & W ee sawir midab leh. Tijaabinta iyo qaladka guud ahaan waa habka ugu fiican. Qaababka ugu ballaadhan ayaa loo adeegsadaa ikhtiyaarrada "rogaalka galka" or "desaturation" (ama "ka saarista midabka") ikhtiyaariga ah ee muuqaalka software-ka.

Ku beddel Grayscale

Mid ka mid ah siyaabaha ugu fudud iyo inta badan ee ugu fiican ee lagu heli karo midabka midabada midabka midabada leh waa inuu u beddelo si Grayscale - doorasho caadi ah ee software-ka muuqaal-celinta. Marka loo beddelo sawirka RGB-ka midabka sawirada midabkiisa oo dhan waxaa lagu beddelay midabada cawliga. Sawirku mar dambe kuma jiro RGB.

Waraaqaha sawirada sida RGB si aad mararka qaar u gaarto natiijooyin daabacan oo wanaagsan haddii aad u rogto sawirada dib ugu soo noqoshada RGB ka dib markaad gogol-xajinayso - waxay weli ahaan doontaa midabyo cadaan ah.

Desaturation (Ka saar Rikoodhada)

Doorasho kale oo aad uga socotid midab si aad u iftiimiso midabkiisu waa miisaan. Qaar ka mid ah barnaamijyada muuqaalka sawirada ayaa jira doorasho deganaansho. Kuwo kale waxay ugu yeeraan ka saarista midabka ama waxay u baahan tahay inaad isticmaasho koontaroolka faafa si aad u gaarto arrintan.

Haddii qiimaha RGB ee muuqaalku uu yahay mid aan muuqaal lahayn (midabka laga saaro) qiimaha mid kastaa waa isku mid ama ku dhowaad isku mid ah midab kasta, taas oo keenta hooskii madow ee dhexdhexaad ah.

Desaturation waxay ujirta midabka Casaanka, Cagaaran, iyo buluugga ah ee cagaarka. Sawirka wuxuu weli ku jiraa Colorbace RGB, laakiin midabada waxay u jeedisaa casriga ah. Natiijooyinka sharaxaadda ee muuqaal u muuqda inuu yahay mid naxwi ah, ma aha.

Grayscale iyo Desaturation iyo Habab kale oo Bedelaad

Marka la eego, muuqaalka midabka midab ah ayaa loo beddelay naxwaha iyo hoos u dhigidda wareegyada gariirka. Ficil ahaan, khilaafyada yaraanta ayaa laga yaabaa inay muuqdaan. Sawirka muuqaalku wuxuu noqon karaa wax yar oo madow waana lumin karaa faahfaahin faahfaahsan marka loo eego sawirada isla sawirada naxwaha dhabta ah.

Waxay u kala duwanaan kartaa hal sawir ilaa kan xigta, khilaafyada qaarna maaha kuwo cad oo muuqaalka ilaa sawirka la daabaco. Maxkamadeynta iyo qaladka waxay noqon kartaa habka ugu fiican ee loo shaqaaleeyo.

Qaar ka mid ah habab kale oo loo abuuro muuqaal sawiro ah oo ka sameysan sawir midab leh:

• Ku baddel qaabka LAB oo laga saaro oo kaliya kanaalka Luminance ee madow & caddaan. Natiijadu waa wax aad u qurux badan sida habka garaaca.
• Ka saar mid ka mid ah kanaalada RGB ama CMYK, adoo isticmaalaya ama isku daraya dhowr channel si aad u hesho saameynta aad rabto.
• Intii aad ka qaadi lahayd midabtakoorka oo dhan si siman, u adeegso xakamaynta Hue / Saturation si aad u sharaxdo channel walba si shakhsiyan ah saameyn caadada ah.
• Abuuri halbeeg (midab aan ahayn madow) ama duotoon loogu talagalay mid aan ahayn midab aan ahayn, mid aan ahayn madow iyo cadcad.

Sawirro Sawirada Sawirada Sawirada Sawirada sida Madow iyo Caddaan

Marka lagu daabaco khad madow, sawirada naxwaha leh waxay u soo noqotaa qaabka dhibco madow oo simulates codadka joogtada ah ee sawirka asalka ah. Goobaha ciriiriga ee cirka ah waxay ka kooban yihiin dhibco yaryar ama yar oo madow oo kala fog. Sawirada madow ee cawlka waxaa ku jira dhibicyo madow ama ka weyn oo leh xargo dheeri ah.

Marka, marka la daabaco sawirada naxwaha leh khad madow waxaad runtii ku daabacdaa sawir B & W sababtoo ah badhkoodu waa madow khad madow.

Waxaad soo saari kartaa nuska nambarka tooska ah ee tooska ah ee kombuyuutarka. Saameyntii nuska ah ee la isticmaalo waxaa laga yaabaa in lagu qoro daabacadahaaga PPD (PostScript Printer Driver) ama gaar ahaan barnaamijka software-ka.

Marka la daabaco sawirada B & W ee daabacaadda khadadka ah, natiijooyinka waxaa lagu kala duwanaan karaa iyadoo la daabacayo khad madow oo kaliya ama u oggolaanaya in printer-ka uu isticmaalo miro qurxin si uu u daabaco midabada cawliga. Midabka isbeddelka - laga bilaabo dayac-darro si cad - laga yaabo inay dhacdo marka la isticmaalayo moofo midab leh. Si kastaba ha ahaatee, khadka madow oo kaliya ayaa lumin kara qaar ka mid ah faahfaahinta ugu dambeysa oo keenaya dhibco cad oo khafiif ah - badhkeed oo la ogaan karo.

Wixii daabacaadda ganacsi, ka tag sawirada sawirada qaabka sawirada illaa mooyee bixiyahaaga adeeggaaga soo jeedin kale. Iyada oo ku xiran habka daabacaadda, shaashadaha madow iyo caddaanka nuska ah ayaa aad uga dhib badan waxa ka mid ah qaar ka mid ah daabacadaha mashiinka shaqada ah. Si kastaba ha ahaatee, waxaad muujin kartaa shaashadahaaga software-kaaga haddii aad door bidayso (ama aad abuurto waxyaabo gaar ah).
