njira zosiyana yosavuta osati kwambiri ...

Ngati mulibe kumafuna njira osiyanasiyana mungagwiritse ntchito Adobe Acrobat. Atatero, mungathere file kutembenuka basi. Kumene tikhoza osiyana kwambiri: ndi psinjika wangwiro ndi inu simungapeze.

Njira ina, chimene chimafuna kudziwa zina, - kugwiritsa ntchito Photoshop. Pankhaniyi n'zotheka kukwaniritsa pazipita psinjika chiŵerengero wa chinthu pafupifupi popanda imfa ya khalidwe.

Ntchito Photoshop, mukhoza kuchita PDF kukula kuchepetsa kugwiritsa ntchito yabwino pa Intaneti. Area "psinjika" mu kaundula psinjika kukambirana bokosi ali m'magawo atatu osiyana. Aliyense wa iwo lili mungachite kuti psinjika fano ndi resampling izo. Kodi kuchepetsa kusamvana? Ngati mukufuna kugwiritsa ntchito file pa maukonde, ndiye zizichitidwa. Ngati mukufuna kupala yosindikiza ina, chigamulocho sayenera kusintha zoikamo! Zimitsani menyu, omwe amapereka ntchito downsampling.

Iwo downsampling yodziwika kuti amachepetsa chiwerengero cha pixels pa chithunzichi. Kugwiritsa ntchito fano, sankhani sanaike, kenako lowetsani chigamulocho mukufuna. Komanso, inu mukhoza kusankha makondawa, njira imene mafano onse amene kusamvana ndi apamwamba kuposa phindu mwalowa, adzakhala basi kuotcha. Koma kamodzinso, tiona kuti PDF psinjika popanda imfa ya khalidwe - ndondomeko ndi zovuta kwambiri, ndipo ntchito si nthawi zonse kufikapo.
