M'nkhani yanga yomaliza ya GIMP yothandizira, ndidalemba mutu wa kusanja kuwonekera mu GIMP - kufotokoza kuti zigawo za wosanjikiza zimatha kufufutidwa kuti ziwonetse mtundu (popanda njira ya alpha yomwe imayikidwa pagawo) kapena maziko owonekera. Nkhaniyi idaphimba lingalirolo pochotsa ma pixel mwachindunji pagawo, lomwe ndidatchulapo kuti linali njira yowononga kwambiri yosinthira.

Komabe, mumatani mukafuna kufafaniza kapena kubisa gawo la wosanjikiza m'njira yosawononga?

Yankho losavuta pa izi ndikuti mumagwiritsa ntchito a chigoba chosanjikiza.

Kodi Layer Mask ndi chiyani?

Mwa kutanthauzira kwa gulu la GIMP, masks osanjikiza "amakulolani kuti musinthe mawonekedwe (kuwonekera) kwa wosanjikiza [masks osanjikiza] a. Izi zimasiyana ndi kugwiritsa ntchito layer Opacity slider popeza chigoba chimakhala ndi kuthekera kosintha mawonekedwe a madera osiyanasiyana pagawo limodzi. ”

Kuti muchepetse izi m'mawu osavuta, muyenera kumvetsetsa mfundo zosavuta za masks osanjikiza.

Poyambira, masks osanjikiza amayikidwa pamwamba pa gawo lanu loyambirira ngati mtundu wowonjezera. Mukayika pamwamba pa wosanjikiza wanu, chigoba chosanjikiza chikhoza kukhala chimodzi mwamitundu itatu - yakuda, yoyera, kapena imvi. Mitundu iyi, ikakhala pa chigoba chosanjikiza, imayimira kuwonekera kwathunthu, kusawoneka bwino, kapena kuwonekera pang'ono motsatana. Chifukwa chake, ndikapaka zakuda pachigoba changa chosanjikiza, ma pixel aliwonse omwe ali pansi pa malo omwe ndidapaka wakuda tsopano abisika pagawo lomwe lili ndi chigoba chosanjikiza. Ngati ndipaka imvi pa chigoba chosanjikiza, ma pixel kuchokera pamenepo azikhala owonekera pang'ono. Ngati ndipaka zoyera pa chigoba chosanjikiza, ma pixel amenewo adzakhala opaque kwathunthu - kotero zikuwoneka ngati palibe chomwe chachitika ku gawolo.

Chifukwa chake, chigoba chosanjikiza chimakhala ndi imodzi mwa ntchito zitatu - zikhala zowonekera kwathunthu, zowoneka bwino, kapena zowonekera pang'ono.

Kuti mumveketse bwino mfundo imeneyi, ndiroleni ndikusonyezeni chitsanzo.
