Luna Hoʻokele Paʻa a pololei
He lula maʻalahi kēia e hiki ke hoʻohālikelike ʻia i ka nui maoli, nā ana i ke knm, mm a me ka ʻīniha, ʻo ka hapa luna ka lula millimeter a me ka ruler centimeter, ʻo ka hapa haʻahaʻa he lula ʻīniha. I mea e ana pono ai i ka lōʻihi o kāu mea, manaʻo ikaika mākou e calibrate mua i kēia ruler online, e hoʻonohonoho i nā pixels pololei i kēlā me kēia ʻīniha i kāu hāmeʻa ponoʻī, ma hope o ka hoʻoponopono ʻana, e loaʻa iā ʻoe ka lula pololei loa ma ka pūnaewele.
Pehea e hoʻololi ai i kēia aliʻi virtual i ka nui maoli
No ka loaʻa ʻana o ka mōʻī pololei loa ma ka pūnaewele, e hoʻonohonoho wale i nā pika no ka ʻīniha (PPI), ma lalo nei kekahi mau ala e ʻike ai i nā pika i kēlā me kēia ʻīniha i kāu hāmeʻa.
- He pale ākea kaʻu kamepiula (13.6"x7.6"), a ʻo ka hoʻonā ʻana he 1366x768 pixels, 1366 / 13.6 = 100.44 PPI. ʻO 1366x768 pixels ka hoʻonā pale o kāu hāmeʻa o kēia manawa.
- Huli i ka "hōʻike ʻia e ka pixel density" ma ka pūnaewele, e nānā inā loaʻa ka hōʻailona a me ke kumu hoʻohālike o kāu hāmeʻa, laki wau a loaʻa i kaʻu pale he 100 PPI.
- E hoʻohana i nā mea maʻamau e hoʻohālikelike i ka lōʻihi, e nānā i kāu ʻeke, e hoʻohana i kekahi kālā pepa e lilo i mea hoʻohālikelike, a laila e ʻimi "ka laulā o kāu kālā pepa" ma ka pūnaewele, ke ʻike ʻoe i ka laulā, hiki iā ʻoe ke hoʻololi i ka hoʻonohonoho PPI o ke aliʻi e ia, ʻo ʻoe. hiki ke hoʻohālikelike i kekahi mea nui maʻamau ma kou ʻaoʻao, e laʻa, ke kālā, kāleka hōʻaiʻē, CD, kālā pepa, kelepona paʻa, i loko o ke keʻena, he pepa hiki ke paʻi ʻia ka nui A4 he mea hoʻohālikelike maikaʻi, ʻoi aku ka lōʻihi o ka pololei. Ma lalo o ka ruler adjuster e kōkua iā mākou e calibrate pololei i ka maʻalahi.
- ʻO ke ala pololei loa, ma hope o koʻu ana ʻana i ka nui o ke aliʻi virtual e kahi aliʻi maoli, ʻike wau ʻaʻole pololei loa nā māka ma 30cm, no laila hoʻoponopono wau i nā pika paʻamau i kēlā me kēia ʻīniha (PPI) i 100.7, i kēia manawa ua loaʻa iaʻu ka virtual pololei loa. luna ma ka pūnaewele.
- Loaʻa i kēlā me kēia hāmeʻa kāna PPI ponoʻī, e laʻa. ʻO kaʻu kamepiula Asus he 100.7 PPI, ʻo Apple MacBook Air ka 127.7 PPI, ʻo Xiaomi Mi Pad 3 ʻo 163 PPI, ʻo kaʻu mau kelepona paʻa (Sony Xperia C5, OPPO R11 Plus) ʻelua 122.6 PPI, ʻo Apple iPhone 5 ʻo 163 PPI, iPhone 7 ʻo 162 PPI, iPhone X he 151.7 PPI.
