Tsamba ili lidzakusonyezani momwe mungagwiritsire ntchito mafano pogwiritsa ntchito mzere wa malamulo a Linux.
Mudzapeza momwe mungasinthire fano yonse potsata kukula kwa fayilo ndi kukula. Mudzaphunziranso momwe mungasinthire pakati pa ma foni osiyanasiyana monga JPG ku PNG kapena GIF ku TIF .
The Convert Command
Lamulo losinthira limagwiritsidwa ntchito kusintha fano. Maonekedwe ndi awa:
Sinthani fayilo yolowera [zolowera zosankha] [output output] file output.
Mmene Mungasinthire Zithunzi
Ngati mukufuna kujambula chithunzi pa tsamba la webusaiti ndipo mukufuna kuti mukhale kukula kwake ndiye mungagwiritse ntchito CSS kuti musinthe fano.
Zili bwino ngakhale kuti muzitha kujambula chithunzicho monga kukula koyambirira ndikuyika izo patsamba.
Ichi ndi chitsanzo chimodzi chokha chomwe mungayesere kuti mukhale ndi fano .
Kusintha fano kugwiritsa ntchito lamulo lotsatira
kusintha imagename.jpg -resize miyeso latsopano.jpgame.jpg
Mwachitsanzo, kutembenuza chithunzi kukhala 800x600 mungagwiritse ntchito lamulo ili:
kusintha imagename.jpg -resize 800x600 new.jpgame.jpg
Ngati mwakutembenukira ku miyeso yowonjezera chiwerengero cha chiwerengerocho chidzasokoneza chithunzicho chidzasinthidwa ku chiwerengero chapafupi kwambiri.
Kukakamiza kutembenuka kukhala kukula kwenikweni, gwiritsani ntchito lamulo ili:
kusintha imagename.jpg -resize 800x600! new.jpgame.jpg
Simusowa kufotokozera kutalika ndi m'lifupi monga gawo la lamulo lokhazikika.
Mwachitsanzo, ngati mukufuna kupitilira 800 ndipo simusamala za kutalika mungagwiritse ntchito lamulo ili:
kusintha imagename.jpg -resize 800 new.jpgame.jpg
Kuti musinthe fano kuti mukhale kutalika mumagwiritsa ntchito lamulo ili:

Momwe Mungatembenuzire Kuchokera ku Fomu Yoyamba ya Zithunzi ku Mzake
Ngati muli ndi fayilo ya JPG ndipo mukufuna kuti mutembenuzire ku PNG mungagwiritse ntchito lamulo ili:

Mmene Mungasinthire Fayilo Kukula kwa Zithunzi
Pali njira zingapo zosinthira kukula kwa fayilo ya fano.
- Sinthani mbali ya chiwerengero (ikhale yaing'ono)
- Sinthani mtundu wa fayilo
- Sinthani khalidwe la kupanikizika
Kuchepetsa kukula kwa fano kudzapangitsa kukula kwa fayilo kukhala kochepa. Kuwonjezera apo, kugwiritsa ntchito fayilo maonekedwe omwe akuphatikizapo kupanikizika monga JPG kudzakuthandizani kuchepetsa kukula kwa mafayilo.
Potsirizira pake kusintha khalidweli kumapangitsa fayilo yathupi kukula.
Zigawo ziwiri zapitazo zikuwonetsani momwe mungasinthire kukula ndi mtundu wa fayilo. Kupondereza chithunzi kuyesa lamulo ili:
kusintha imagename.jpg -quality 90 newimage.jpg
Mtengo umatsimikiziridwa ngati peresenti. Zomwe zili m'munsizi ndizochepa zochepa zomwe zimatulutsidwa, koma mwachiwonekere zotsirizazo zimakhala zabwino.
Momwe Mungasinthire Zithunzi
Ngati mwajambula chithunzi mujambula koma mukufuna kuti chikhale chithunzi cha fano mungathe kusintha fanolo pogwiritsa ntchito lamulo ili:
chithunzi.jpg.jpg -rotate 90 newimage.jpg
Mukhoza kufotokoza mbali iliyonse yoyendayenda.
Mwachitsanzo, yesani izi:

Sinthani Zosankha Zamanja Lamulo
Pali mitundu yambiri ya mzere wa mauthenga omwe angagwiritsidwe ntchito ndi lamulo lomasulira monga momwe taonera apa:
Zosankha zikugwiritsidwa ntchito mndandanda wa malamulo. Njira iliyonse yomwe mumayimilira pa mzere wa malamulo ikugwirabe ntchito pazithunzi zotsatila, mpaka pangidwe lichotsedwe ndi mawonekedwe aliwonse kapena -noop . Zosankha zina zimakhudza kuwonetseratu zithunzi ndi ena kokha kododometsa. Zomalizazi zikhoza kuwonekera pambuyo pa gulu lomaliza la zithunzi zolembera.
