Thanks in ay image ah waa la dhimi karaa ama kor u kacay, halka ixtiraamaya Joogaba, loo baahan yahay kuwaas oo la tilmaamay in sawiro. Waa maxay miisaanka aynu hore u garan, si aan ka hadalno labo nooc ka mid ah.

zoom kordhinta

Noocaan waxaa loo isticmaalaa in kiiska halkaas oo image nolosha-size si weyn u yar yahay in sawiro. Xaaladdan oo kale, in sanduuqa lagu tilmaamay Joogaba, image la siiyey (2: 1, 8: 1, 16: 1, 150: 1, iyo wixii la mid ah). Joogaba, waa in la fahamsan yahay sida soo socota: tirada saxda ah waxay muujinaysaa in sawir oo dhan waa in la kala qaybiyaa sentimitir (tus, 1 cm), oo bidix - imisa jeer wax laga dhimayaa 1 centimitir image barbaro. Taasi waa, haddii aan naqshada of 2: 1, waxaa loola jeedaa in 1 centimitir sawir line dhaco 0.5 wax centimitir.

Noocaan waxaa loo isticmaalaa in haddii shayga in aad rabto in aad muujiso, inta ka sareeya ka badan dhinacyada sawirka. In a Joogaba, column gaar ah, waxaan sheeg inta jeer ee wax ka wada weyn yahay image (tusaale ahaan, 1: 2, 1: 250, 1: 1000 iyo wixii la mid ah). tiradaasi ka tagay waxay muujinaysaa sida sentimitir badan sawir waa in la kala qaybsan (tus, 1 cm), iyo xaq - sida halbeeg lagu qiyaaso warsan 1 centimitir. Tusaale ahaan, waxaan leenahay map muujinaya baaxadda 1: 2,000,000, arki, taas macnaheedu waa in 1 card centimitir xisaabay 2,000,000 aagga centimitir (ama 20,000 mitir, ama 20 kilomitir 1 sentiimitir).

Sida loo ucabirto sawiro

Aad u fudud in la diyaarinta maps ama sawirro ka qabtaan, laakiin taasi waxa weeye waxa baaxadda photos ka, waa kuwo ku adag in la fahmo. images noocan oo kale ah ay leeyihiin oo xuduudaheedu cabbirka kala duwan, kuwaas oo xalka, kaas oo ay ku xiran tahay tirada pixels ku yaalla image ah. images u qaadidda, aad u baahan tahay in fiiro gaar ah u tirada pixels, waayo si weyn u sii kordhaya ee size of sawirka leh tiro yar oo ah pixels, waxaan sii xumaanayso oo ay tayada iyo qeybsanaan. Waxaa jira barnaamijyo kala duwan oo loo isticmaali karo in lagu fuliyo hawlaha kuwan, tayada image ka darnaada wakhtiga. Ay mabda 'ee hawlgalka ku salaysan yahay kordhinta tirada pixels in sawir siiyey, markaa si ay kordhaan xallinta, i.e. size ee image ku soo saari. barnaamijyada noocan oo kale ah waxaa laga heli karaa dukaamada qaaska ah ama ka soo bixi internetka, laakiin waxaa wanaagsan in la iibsado giraangiraha liisan leh, oo aan kala soo bixi nuqul oo burcadnimo ah oo xaqiro laga yaabaa in waxqabadka of your computer oo aad u macquul ahayn si loo farsameeyo sawirada it on.
