Kodi sikelo? Scale zithunzi, mapu lonse

Ife tonse tikudziwa zimene lonse. chiŵerengero Izi liniya mu kukula kwa ochiritsira chifaniziro mawonekedwe a makhalidwe abwino a chinthu imaged. Ndiko kuti, ndi kusunga magawo ena pa ntchito zojambula kapena fano kusintha zithunzi iliyonse.

Kodi lonse, ndipo n'chifukwa chiyani muyenera izo

Njira imeneyi imagwira ya kufala kwa fano ntchito zonse mwamtheradi kwa mapu ndi zojambula, kutsiriza ndi zithunzi mwachizolowezi. Koma zimenezo ziri Sizotheka kuti kubereka fano analakalaka chachikulu. Pankhaniyi, amathandiza ndi sikelo. Ndiyamika kuti fano angathe kuchepetsedwa kapena kuchuluka, pamene lokhudza kufanana zofunika zimene anasonyeza mwa zojambula lapansi. Kodi sikelo ife tikudziwa kale, kotero tiyeni tikambirane za mitundu iwiri ya izo.

Sinthani makulitsidwe

Mtundu ntchito ngati kumene fano moyo kukula kwambiri kakang'ono kuposa mu zithunzi ndi. Pankhaniyi, mu bokosi anasonyeza kufanana chithunzi anapatsidwa (2: 1, 8: 1, 16: 1, 150: 1, ndi zina zotero). Kufanana ayenera kumvetsa motere: chithunzi chabwino limasonyeza kuti zojambula lonse kugawidwa masentimita (mwachitsanzo, 1 cm), ndi lamanzere - kangati chinthu yafupika ndi 1 centimeter kujambula chithunzi. Ndiko kuti, ngati tili ndi zoti 2: 1, zikutanthauza kuti 1 centimeter Mzere kugwa 0.5 centimeter chinthu.

Onerani patali

Mtundu ntchito ngati chinthu chimene mukufuna amasonyeza, apamwamba kuposa miyeso zojambula. Mu kufanana wapadera mzati, ife mwachindunji kangati chinthu amkulira fano (mwachitsanzo, 1: 2, 1: 250, 1: 1000 ndi zina zotero). Chithunzi kumanzere zikusonyeza angati masentimita zojambula uwagawire (mwachitsanzo, 1 cm), ndi bwino - monga kuyeza mayunitsi mlandu 1 centimeter. Mwachitsanzo, tili ndi mapu kusonyeza lonse la 1: 2,000,000, onani, izi zikutanthauza kuti 1 centimeter khadi nkhani 2,000,000 centimeter m'dera (kapena mamita 20,000, kapena makilomita 20 pa 1 centimeter).

Kodi kuti musinthe kukula kwa zithunzi

zosavuta kuthana ndi yokonza mapu kapena Zojambula, koma ndicho chimene lonse zithunzi, ndi kovuta kumvetsa. Zithunzi oterowo magawo osiyana muyeso, ndicho chigamulocho, potsata chiwerengero cha pixels ili pa chithunzichi. Makulitsidwe images, muyenera tcheru ndi chiwerengero cha pixels, chifukwa kwambiri kukula kukula kwa chithunzi ndi ochepa pixels, ife poipa ubwino wake ndi mosemphanitsa. Pali ntchito zosiyanasiyana zomwe zingagwiritsidwe ntchito kugwiritsa ntchito izi, fano khalidwe kungawonjezeke kwambiri. Mfundo amagwirira ntchito zawo zachokera kuwonjezera chiwerengero cha pixels mu chithunzi kuperekedwa, potero kukula kusamvana, i.e. kukula kwa fano chinaonekeranso. Mapulogalamu amenewo angapezeke mu masitolo zapaderazi kapena dawunilodi pa Intaneti, koma ndi bwino kugula mawilo chiphatso, osati koperani magazini pirated omwe mwina amanyoza ntchito kompyuta yanu ndi kupanga izo kukhala zosatheka pokonza zithunzi pa izo.
