Ngisusa kanjani isizinda esithombeni sami?
Mhlawumbe umbuzo obabuzwa kaningi mayelana nesofthiwe yehluzo, "Ngisusa kanjani isizinda esithombeni sami?". Ngeshwa akekho impendulo eyodwa elula ... kunezinamba eziningi ongayithatha. Lowo okhethayo kuningi okwenzayo nge-software yakho, isithombe esithile osisebenzisayo, okukhiphayo kokugcina (ukuphrinta noma i-electronic), nomphumela wokuphela oyifunayo. Lokhu kuboniswa okubanzi kukuxhumanisa neziqephu eziningana ngolwazi olumayelana nokususa imvelaphi nokulondoloza obala kwi- software yehluzo .
Vector vs. Bitmap Izithombe
Uma izithombe ze-vector zikhahlekile azikho izinkinga zangemuva zokukhathazeka ngazo, kodwa uma isithombe se-vector singeniswa ohlelweni lwepin-based esisekelwe esiteshini noma siguqulwa kwifomathi ye-bitmap isithombe sihlehlisiwe - sichitha izimfanelo zayo ze-vector. Ngenxa yalesi sizathu, kubalulekile ukuthi usebenzise uhlelo lomdwebo njalo lapho uhlela izithombe ze-vector, kanye nenqubo yokupenda uma uhlela izithombe ezifakiwe.

Ukungaqondile nokufometha kwezithombe
Amafomethi wezithombe ezivame kakhulu zewebhu , i- GIF ne-JPEG , ihluzo ezifakwe ku-bitmapped. Lokhu kusho ukuthi bazohlala benemuva. "Kuyini?", Mhlawumbe uthi ... "ngokuqinisekile ubonile izithombe kuwebhu ngezizinda ezicacile!" Uqinisile ngokuphelele; lokhu kungenzeka ngenxa yesakhiwo se-GIF89a. Izithombe ze-GIF89a zinamandla okubeka umbala owodwa emfanekisweni njengento ecacile.Izithombe ze-PNG nazo zisekela obala, kodwa ngokungafani ne-GIF, i-PNG ikuvumela ukuthi uchaze okungaphezu kombala owodwa njengokubonakalayo. Enye inzuzo ye-PNG ukuthi isekela izigidi zembala, kanti i-GIF ilinganiselwe kumbala angu-256 kuphela. Inkinga nge-PNG akuzona zonke iziphequluli ezisekelayo, futhi lezo ezenzayo azihambisani nokusekela kwazo. - Mayelana ne-JPEG
- Mayelana ne-GIF
- Mayelana ne-PNGUma uhlela ukuthekelisa isithombe njenge-GIF noma i-PNG ecacile, kufanele uqiniseke ukuthi uhlelo ozolifaka ukungenisa lolu hlelo luzokwamukela. Ngokuvamile, kufanele usebenzise i-GIF noma iPNG kuphela izithombe ezibonakalayo ohlela ukuyisebenzisa esibukweni. Ukuze uthole okushicilelwe, kufanele ufunde ezinye zezindlela zokudala obala.

Masking Magic
Uma isithombe sakho sinembala eqondile, indlela elula yokuyisusa ngokusebenzisa ithuluzi lakho lomhleli " wamagic wand " ukuze ukhethe masinyane isizinda bese uyisusa. Ngokuchofoza umbala wangemuva ngethuluzi lakho le-magic wand, ukwazi ukukhetha kalula wonke amaphikseli aseduze ngaphakathi kombala ofanayo. Uma unezindawo ezengeziwe, ezingezona eziseduze, kuzodingeka usebenzise ithuluzi le- magic wand futhi kwimodi engezayo ukwengeza ekukhethweni. Bheka ifayela lakho losizo lwe-software ukuze uthole ukuthi ungakwenza kanjani lokhu.
Uma isithombe sakho sinemvelaphi engesiqinile, inqubo yinkimbinkimbi kakhudlwana ngoba kuzodingeka ufihle ngesandla indawo okufanele isuswe. Uma une ndawo efihliwe ungakwazi ukususa indawo efihliwe, noma ukuguqula imaski yakho futhi ukopishe into kusuka ekukhethweni. Vakashela izixhumanisi ezilandelayo ukuze ufunde kabanzi mayelana namaski kanye namathuluzi othize we-masking namasu:
- Wonke amaMasks aseGreyyscale
- Ukususa izendlalelo nge-Photoshop
- Amaski ku-Paint Shop Pro
- Amaski e-Corel Photo-Paint
- Khipha i-White and Eliminate Black Filters
Ngezithombe ezinezizinda eziyinkimbinkimbi kakhulu, kukhona isofthiwe eyenzelwe ngokukhethekile ukwenza lezi zikhetho ezinzima nokuyeka ngemuva.
Uma usuqedile into, ungayilondoloza njenge-GIF noma i-PNG ebonakalayo bese usebenzisa isithombe kunoma yiluphi uhlelo olusekela ifomethi ekhethiwe. Kodwa kuthiwani uma uhlelo lwakho alusekeli lezi zakhiwo?
Umbala Wokudonsa Nombala Wemibala
Izinhlelo eziningi zinamandla okungena ngaphakathi, noma imaski, umbala owodwa esithombeni. Isibonelo, umbhalo we- Microsoft Umshicileli wokuqopha umyalelo wesithombe uzokhipha ngokuzenzakalelayo amaphikseli amhlophe esithombeni. Ngethuluzi lamaski e- bitmap ye-CorelDRAW, ungakhetha imibala ukuthi isuswe esithombeni. Lokhu kunikeza ukuguquguquka okuncane okunye ngoba ungacacisa umbala ongaphezu komunye, lawula izinga lokubekezela lombala ocijiwe, futhi isebenza izithombe ezinombala ongemuva ngaphandle kwezimhlophe. Kungase kube khona ezinye izinhlelo zokusebenza ngalezi zindlela zokusebenza; thintana namadokhumenti akho ukuze uthole.
- Indlela Yokususa Ingemuva Ku-Bitmap Ukusebenzisa i-Bitmap Color Mask ku-CorelDraw Kukhona ezinye izinselele kulezi zindlela, noma kunjalo. Okokuqala ukuthi le misebenzi izosebenza kuphela ngaphakathi kwaloluhlelo oluthile. Ngokuvamile awukwazi ukukhipha umbala ku-CorelDRAW, unamathisele isithombe sibe olunye uhlelo, futhi ube nezindawo ezibala. Enye indlela yokuyeka ukuthi i-toolout yokulahla isebenza ngendlela yokuthi ilahle zonke izimo zalowo mbala futhi kungase kube nezimo zalowo mbala kwezinye izingxenye zesithombe esinye nesimo sangemuva. Lokhu kubangela "izimbobo" ezingaqondakali esithombeni sakho.
- Uma ukudonsa nokukhishwa kombala akusebenzeli isithombe sakho, enye inketho ongase ukwazi ukuyisebenzisa ibizwa ngokuthi ucezu, u-trim, isiqeshana, noma imaski. Lokhu kwenziwa ngokudweba i-vector shape, besebenzisa uhlaka lwe-vector ukusika, noma isisindo, isithombe se-bitmap .
- Indlela yokwenza i-Bitmap nge-Vector Shape ne-CorelDraw sika-PowerClip Isici Uma uke ukhathala zonke izinketho ezingenhla, futhi awukakutholanga imiphumela efunayo, yisikhathi sokubheka ukuthi yini eningayenza ngekhompyutha yakho yesikhali kanye nezindlela zokuchofoza.
- Imigudu efakiwe kanye neziteshi ze-Alpha Uma unezithombe ezibonakalayo, cishe uzofuna ukwenza okuthile ngakho. Lesi sihloko esilandelayo sichaza indlela yokusingatha izimo ezivame kakhulu.
