Kukonza, kusinkhasinkha, ndi kukula kwa mafilimu ndi nkhani yaikulu komanso yosokoneza nthawi zambiri, ngakhale kwa opanga nzeru. Zomwe zimafalitsa pakompyuta zatsopanozi zingakhale zodabwitsa. Musanachite mantha poganizira zomwe simukudziwa zokhudza kuthetsa vutoli, ganizirani zomwe mumadziwa komanso zofunikira, zosavuta kumvetsetsa.
Kodi Kusintha N'kutani?
Monga momwe imagwiritsidwira ntchito pa kusindikiza ndi kupanga mapulogalamu, chigamulo chimatanthauzira madontho a inki kapena magetsi apakompyuta omwe amapanga chithunzi ngati amasindikizidwa pamapepala kapena amawonetsedwa pawindo. Mawu akuti DPI (madontho pa inchi) mwinamwake amadziwika bwino ngati mwagula kapena mumagwiritsa ntchito printer, scanner, kapena kamera ya digito. DPI ndiyeso imodzi ya chigamulo. Kugwiritsidwa bwino, DPI imangotanthauza kuthetsa kwa wosindikiza .
Machaputala, Pixel kapena Chinanso?
Zina zoyamba zomwe mungakumane nazo zomwe zikutanthauza kusamvana ndi PPI ( pixels per inch ), SPI (zitsanzo pa inch), ndi LPI (mizere pa inchi). Pali zinthu ziwiri zofunika kuzikumbukira paziganizo izi:
- Liwu lirilonse likutanthauza mtundu wosiyana kapena chiyeso cha chisankho.
- Pa makumi asanu peresenti kapena nthawi yochuluka yomwe mukukumana nayo malingaliro awa, iwo adzagwiritsidwa ntchito molakwika, ngakhale mkati mwazithunzi zanu zosindikiza kapena mapulogalamu a zithunzi.
M'kupita kwa nthawi, mudzaphunzira momwe mungagwiritsire ntchito chiganizochi. M'nkhaniyi, tidzangotchula za chigamulo monga madontho kuti zinthu zikhale zosavuta. (Komabe, madontho ndi DPI sali mawu oyenerera pa china chilichonse kupatulapo chigulitsidwe kuchokera kwa wosindikiza. Ndizodziwika bwino komanso zosavuta.)
Ndi Machaputala Angati?
- Kaya amasindikizidwa pamapepala kapena kuwonetsedwa pa kompyuta yanu, chithunzi chili ndi madontho ang'onoang'ono.
- Pali madontho a maluwa ndipo pali madontho wakuda. Mu zojambula zakuda ndi zoyera, kukula ndi mawonekedwe a madontho wakuda ndi momwe amawasindikizira pafupi kapena apatali amatenga chithunzi cha mithunzi ya imvi.
- Machaputala aang'ono omwe amagwiritsidwa ntchito (mpaka kufika pazithunzi) chithunzi chowonekera bwino.
- Madontho ambiri pachithunzi, ndi aakulu kukula kwa fayilo yojambula.
- Kusintha kumayesedwa ndi chiwerengero cha madontho mu inchi yosakanikirana kapena yowonekera.
- Choyimira chilichonse, ( scanner , kamera yamakina , makina osindikiza , makompyuta a makompyuta ) ali ndi malo ambirimbiri omwe angapangidwe ndi kuwonekera ngakhale kuti pali madontho angati.
Zitsanzo Zosankha
Pulogalamu ya Laser 600 DPI ingasindikize mpaka madola 600 a chithunzi cha chithunzi mu inchi. Kuwunika kompyuta kumatha kusonyeza 96 zokha (Mawindo) kapena maola 72 (Mac) a zithunzi za chithunzi mu inchi.
Pamene chithunzi chili ndi madontho ambiri kuposa chipangizo chowonetsera chitha kuthandizira, madontho amenewo amawonongeka. Amawonjezera kukula kwa mafayilo koma samapanga kusindikiza kapena kuwonetsera chithunzichi. Chisankho chiri chapamwamba kwambiri kwa chipangizochi.
Chithunzi chojambulidwa pa 300 DPI ndi 600 DPI chidzawoneka chimodzimodzi pa printer la 300 DPI laser. Mazowonjezako a mauthengawa "amatulutsidwa" ndi wosindikiza koma zithunzi 600 za DPI zidzakhala ndi kukula kwa mafayilo.
Pamene chithunzi chili ndi madontho ochepa kusiyana ndi chipangizo chowonetsera chingathandizire, chithunzichi sichitha kukhala chowonekera kapena chakuthwa. Zithunzi pa intaneti nthawi zambiri ndi 96 kapena 72 DPI chifukwa ndicho chigamulo cha ambiri oyang'anira kompyuta. Ngati mumasindikiza chithunzi 72 cha DPI ku printer 600 DPI, sichidzawoneka bwino monga momwe imachitira pa kompyuta. Wosindikiza alibe madontho okwanira achidziwitso kuti apange chithunzi chowoneka bwino. (Komabe, makina osindikizira a inkjet lero amakonza ntchito yabwino kwambiri yopanga zithunzi zosakanikirana bwino zikuwoneka bwino kwambiri nthawiyo.)
Tsegulani Dots of Resolution
Mukakonzekera, funsani momveka bwino zenizeni zokhudzana ndi kuthetsa komwe mungaphunzire mayankho ogwirizana ndi momwe DPI, PPI, SPI, ndi LPI zilili. Mwinanso mutha kuphunzira zambiri za kusindikizidwa kwa halftone , zomwe zikugwirizana ndi nkhani yothetsera.
