Uyini esikalini? Scale izithombe, amabalazwe isikali

Sonke siyazi ukuthi isikali. Lesi isilinganiso lwento ubukhulu ukumelwa ezivamile sokuqhafaza amagugu into imaged kweqiniso. Okungukuthi, kuba ngokugcinwa ngezabelo ezithile phakathi ukubhalisa kwanoma iyiphi umdwebo noma ukuhlela isithombe izithombe.

Uyini esikalini, futhi kungani uludinga

Le ndlela yokudlulisela yesithombe lisetshenziswe ngokuphelele konke kusuka amabalazwe kanye nemidwebo ziphethe izithombe evamile. Kodwa lokho nje ngaso sonke isikhathi ukuthi ukukhiqiza kabusha isithombe oyifunayo ngosayizi ophelele. Kulokhu, kuziwa ukulekelelwa esikalini. Ngenxa-ke isithombe zingancishiswa noma ukwanda kwemithwalo, ngenkathi kuhlonishwa olinganise kudingekile ezikhonjiswe e imidwebo. Uyini isikali esikwaziyo kakade, ngakho ake sixoxe ezimbili izinhlobo ke.

Sondeza uyakekela

Lolu hlobo isetshenziswa icala lapho umfanekiso ukuphila-usayizi kakhulu ezincane kuno kule imidwebo. Kulokhu, ebhokisini wabonisa olinganise image okunikeziwe (2: 1, 8: 1, 16: 1, 150: 1, nokunye). Ukuphambana kumele aqondwe njengokufaka elandelayo: sibalo engakwesokudla iveza ukuthi umdwebo wonke kufanele ihlukaniswe amasentimitha (isib 1 cm), kanye kwesokunxele - kukangaki into kuyehla 1 isentimitha ukudweba isithombe. Okusho ukuthi, uma siba ekubizweni 2: 1, kusho ukuthi 1 isentimitha umugqa umdwebo uwela 0.5 isentimitha into.

zoom out

Lolu hlobo isetshenziswa endabeni uma into ofuna ukuveza, kunalelo umdwebo Ubukhulu. Ngo ikholomu ngezabelo ekhethekile, thina ucacise kukangaki into mkhulu isithombe (isibonelo, 1: 2, 1: 250, 1: 1000 nokunye). Lesi sibalo kwesokunxele kubonisa indlela amasentimitha eziningi umdwebo kufanele ihlukaniswe (isib 1 cm), kanye nelungelo - njengoba akhawunti amayunithi wokulinganisa 1 isentimitha. Ngokwesibonelo, sinalo ibalazwe obonisa Esikalini kusukela ku 1: 2.000.000, bheka, lokhu kusho ukuthi 1 isentimitha ikhadi ama-akhawunti 2.000.000 isentimitha endaweni (noma 20,000 amamitha, noma 20 amakhilomitha ayi 1 isentimitha).

Kanjani ukuze ushintshe usayizi izithombe

Kulula kakhulu ukubhekana ukulungiswa amabalazwe noma imidwebo, kodwa yilokho esikalini kwezithombe, kunzima ngempela ukuqonda. izithombe ezinjalo ezahlukene nesilinganiso imingcele, okungukuthi isinqumo, okuyinto incike isibalo Amaphikseli etholakala esithombeni. Ukunciphisa izithombe, udinga ukuba banake inombolo yama-pixels, ngokuphawulekayo okwandisa ubukhulu isithombe inombolo encane yama-pixels, thina ziwohloka izinga layo kanye okuphambene nalokho. Kukhona izinhlelo ezihlukahlukene engasetshenziswa ukuthi siqalise lezi zinhlelo imisebenzi, izinga isithombe siba sibi kakhulu. Isimiso wokusebenza kusekelwe kwandziswa kwelinani letikhungo pixels isithombe unikezwa, ngaleyo ndlela kwande isinqumo, okusho ukuthi, usayizi wesithombe kabusha. Lezo zinhlelo zingatholakala okukhethekile ezitolo noma ukulandwa kusukela Inthanethi, kodwa kungcono ukuthenga amasondo ilayisense, hhayi ukulanda amakhophi pirated zazo kungehlisa ukusebenza ikhompyutha yakho futhi zikwenza ukucubungula izithombe kuso.
