Raster zithunzi ndi ntchito nawo

Pamene ntchito ndi zithunzi ziwiri ooneka enieni, ndikofunika kumvetsetsa ndizosowa matabwa ake ndi mfundo zomwe tidzasandulika, mawu, kuimira monga momwe taonera kompyuta. Wa mitundu iwiri chachikulu cha zithunzi - vekitala ndi raster -each wapeza ntchito zake dera, komanso ali ubwino wake.

Mayunitsi umene bitmaps ndi pixels. Awa ndi ang'onoang'ono mabwalo a polojekiti, amene ananyamula ndi kufalitsa mauthenga mtundu. Ndi thandizo lawo bitmaps apangidwe monga chithunzi, ndipo zazindikirika wonse. Quality polojekiti kusonyeza zithunzi izi zimatengera chiwerengero cha pixels pa inchi. Kwenikweni makompyuta amakono onse chopangidwa ndi Maganizo a pixels 72 kapena 96 pa mamilimita (mtengo imasiyana malingana magawo yotchinga).

Zithunzi Raster akhoza mofulumira kusiyana kwa vekitala ndi kuyang'ana pa kukula kwawo. The akamagwiritsa ambiri chifukwa raster - ndi .gif, .bmp, .png, .jpeg, .psd ndi ena.

Zithunzi Raster akamagwira kupanga file mu Adobe Photoshop ntchito zipangizo zofunika, komanso kuyang'ana zikalata. Komanso, zithunzi zonse kuti mtundu wa zithunzi ziwiri ooneka enieni. Choncho, popanda kusintha mtundu wa mitundu ya owona mu ndondomeko, mukhoza kupewa imfa khalidwe ndi kupotoza mitundu. Ndi kusindikiza zithunzi ntchito yosindikiza, monga bitmap fano.

Translation raster fano mu vekitala ndi mwachilungamo yosavuta yekha kumafuna zithunzi mkonzi zothandiza mitundu onse a zithunzi. Pankhaniyi, pamene inu kupulumutsa chifaniziro chabe amasonyeza vekitala zithunzi mtundu. Komabe, njira imeneyi sikuti zotsatira zabwino. Ndi chabwino kwambiri pamanja redraw ndi bitmap fano mu vekitala, koma pamafunika luso ntchito ndi vekitala zithunzi mkonzi.

Choncho, tiyeni mfundo zikuluzikulu za bitmap fano nsalu yotchinga - ndi mapikiselo gululi, khalidwe la potsata chigamulocho ndi polojekiti yanu. zithunzi amenewa m'posavuta mu mtundu wina. Kupenda pafupi madera awa ali mu mawonekedwe a zithunzi polyline a zigawo mzere ndiwo malire a pixels.

Zithunzi Raster ali, mosakaika, zovuta zawo ndi zofooka, amenenso sitingakane. Mosiyana ndi zithunzi vekitala, zithunzi ngati malire achuluke kusintha zina zikuluzikulu. Ndi kuwonjezeka kwambiri mu kukula kwa bitmap, ndi ayenera kutaya ndalama. Choncho, kusunga ndi mapikiselo zithunzi za kukula lalikulu okwanira motero, ndi zambiri kompyuta kukumbukira. Komanso, raster zithunzi pafupifupi siligwirizana katundu chilungamo. zithunzi okha .gif ndi .png amanenedwa ndi Mbali imeneyi, chifukwa chake khalidwe la mlingo wokwererapo.

Raster mtundu ndi abwino kwambiri amene ali mu mtima kulenga zithunzi ndi mithunzi zovuta ziriri, ndi zina mavuto atatu azithunzi omwe tikunena ndi mawonekedwe. Ndipo, ndithudi, ojambula amene pokonza zithunzi mu Photoshop, amasonyeza yekha bitmap mtundu zojambulajambula.
