Zolemba mlengi: kodi ndi vekitala image, ndipo kodi ubwino wake?

Ndithudi aliyense atamva raster ndi vekitala zithunzi. Komabe, iwo amasiyana pakati pawo? Ndipotu, fano vekitala aumbike kwa ambiri payekha, zinthu scalable. Mosiyana raster, atsimikiza ntchito yapadera maikwezhoni masamu. Izi zikutanthauza kuti zithunzi vekitala kusunga zabwino kwambiri mu zinthu zonse. The zinthu okha mwina zigwirizana zokhotakhota ndi mizere molunjika ndi mosiyanasiyana. katundu wawo Waukulu ndi mtundu, shading, ndi mizere. Ngati wosuta wasintha katundu awa, chinthu si molakwika kapena olumala.

Ubwino waukulu wa zithunzi vekitala - mwayi mwanjira kusintha makulidwe awo. The mizere adzatsala lakuthwa ndi bwino pa nsalu yotchinga kukula kulikonse, ndi kulisindikiza. Mwachitsanzo, onse a zilembo ndi zinthu vekitala. Komanso, mosiyana bitmaps, iwo okha mawonekedwe anayi.

The drawback yekha ndi kuti iwo sangathe ntchito kulenga zithunzi photorealistic. Childs, iwo ntchito gradients woyera ndi mitundu. Ndiko kuti, chotero mitundu kusintha, amene ali lililonse zithunzi akadali sadzapeza kukwaniritsa. Komabe, n'kutheka kuti posachedwapa zinthu zidzasintha. Poyerekeza ndi zaka zam'mbuyo, sayansi ya kulenga zithunzi vekitala ali kwambiri bwino.

ojambula zithunzi Contemporary ndipo okonza akhoza kuyetsa zinthu zowonekera, mithunzi, kusintha yosalala ndi mawonekedwe ngakhale raster, kukwaniritsa mwachibadwa kwambiri. Posachedwapa, zithunzi vekitala amasonkhana yekha ndi zithunzi zojambula. Tsopano iwo ali kwambiri mu mzere ndi malingaliro a Kuzindikira.

Vekitala mafano rasterized popanda mavuto. The ndondomeko n'zosiyana ndi zotheka, koma zambiri zovuta kuzitsatira. Choncho, ngati mukufuna fano rasterized, osati aulesi kwambiri kusunga gwero vekitala payokha. Ngati pambuyo mukufuna kutengera ndi bitmap chithunzi zochokera kulowa chimodzimodzi, koma zikuluzikulu, inu n'zosavuta izo. Komanso musaiwale kuti ngati vekitala chithunzi kutsegula pulogalamu kusamalira zina owona, izo basi kusintha mtundu wake ndi kutaya katundu wawo wapadera. Popewa izi, samalani posankha mapulogalamu.

Pali akamagwiritsa wapadera mafano vekitala. The akuluakulu ndi CDR (CorelDRAW), CGM, WMF, AI (Adobe Illustrator), CMX (Corel Kusinthanitsa) ndi DXF CAD.

Nthawi zambiri, ndi vekitala chithunzi mtundu zitha anatsegula mu pulogalamu inayake. Izi akonzi, mosiyana raster, ndi zambiri zosemphana ndi mzake, kotero kuti fano undistorted zovuta.

Vekitala chithunzi kwenikweni n'kofunika ngati tikulankhula za chilengedwe cha madongosolo, zojambula, Logos, Websites kamangidwe. Ojambula zithunzi ndi okonza padziko lonse mwakhama ntchito zolinga zosiyanasiyana. Ngakhale kuphweka dzikoli likuonekera, vekitala chithunzi zinchito kwambiri, ndipo nthawi zambiri pali zochitika komwe ntchito bitmap sangathe.
