Kusintha kwa Zithunzi: Kodi Ndi Chiyani & Chifukwa Chiyani Ndikofunikira?

pa kim Zasinthidwa: July 9, 2022

Kusintha kwazithunzi ndi kuchuluka kwa tsatanetsatane wa chithunzi. Amayezedwa mkati pixelisi (kapena madontho) muutali ndi m’lifupi, ndipo zimatsimikizira kukula kwa chithunzicho komanso mtundu wake. 

Kusintha kwazithunzi ndikofunikira chifukwa kumakhudza momwe zithunzi zanu zimawonekera komanso momwe zimaperekera uthenga wanu. 

Mu bukhu ili, ndikufotokozerani momwe chithunzi chilili, momwe chimakhudzira zithunzi zanu, ndi momwe mungasankhire chisankho choyenera pa zosowa zanu.

Kodi Image Resolution ndi chiyani?

Kusintha kwazithunzi kwenikweni ndi muyeso wa kuchuluka kwa ma pixel omwe amapakidwa chithunzi. Nthawi zambiri amafotokozedwa mu PPI, yomwe imayimira ma pixel inchi. Ma pixel ochulukira pa inchi, ndiye kuti chiwongolero chake chimakhala chokwera, ndipo chithunzicho chimawoneka chakuthwa komanso chowoneka bwino.

Chimachitika ndi Chiyani Mukasintha Chigamulocho?

Mukasintha kusintha kwa chithunzi, mumanena kuti ndi ma pixel angati omwe mukufuna kuti agwirizane ndi inchi iliyonse ya chithunzicho. Mwachitsanzo, ngati muli ndi chithunzi chokhala ndi 600ppi, zikutanthauza kuti ma pixel 600 adzapanikizidwa mu inchi iliyonse ya chithunzicho. Ichi ndichifukwa chake zithunzi za 600ppi zimawoneka zakuthwa komanso zatsatanetsatane. Kumbali inayi, ngati muli ndi chithunzi chokhala ndi 72ppi, zikutanthauza kuti pali ma pixel ochepera pa inchi, kotero kuti chithunzicho sichidzawoneka bwino.

Ulamuliro wa Resolution of Thumb

Zikafika pakupanga sikani kapena kujambula zithunzi, nthawi zonse yesani kujambula chithunzicho pamlingo wapamwamba kwambiri. Ndi bwino kukhala ndi chidziwitso chochuluka kusiyana ndi chosakwanira! Ndizosavuta kwa mapulogalamu osintha zithunzi, monga Photoshop, kutaya zithunzi zilizonse zosafunikira (monga kuchepetsa kukula kwa chithunzi) kusiyana ndi kupanga zambiri za pixel (monga kukulitsa chithunzi).

Kodi Kusiyana Pakati pa PPI ndi DPI Ndi Chiyani?

Kodi PPI & DPI Ndi Chiyani?

Kodi mumasokonezeka anthu akamalankhula za PPI ndi DPI? Osadandaula, simuli nokha! Ma acronyms awiriwa nthawi zambiri amagwiritsidwa ntchito mosiyana, koma amakhala ndi matanthauzo osiyanasiyana.

PPI (Pixels Per Inch)

PPI imayimira Pixels Per Inch, ndipo zonse ndizabwino Chionetsero kuthetsa. Mwa kuyankhula kwina, ndi chiwerengero cha ma pixel omwe amawonetsedwa mu inchi imodzi ya a digito chithunzi.

DPI (Madontho Pa Inchi)

DPI imayimira Madontho Pa Inchi, ndipo zonse zimatengera kusamvana kwa printer. Izi zikutanthauza kuti ndi chiwerengero cha madontho a inki omwe amasindikizidwa pa chithunzi.
