Esi sikhokelo siza kukubonisa indlela yokusebenzisa imifanekiso usebenzisa umgca we-Linux umyalelo .
Uya kufumanisa indlela yokwenza ishintshi umfanekiso ngokubini ngobukhulu befayile nakwizinga. Uya kufunda kwakhona indlela yokuguqula phakathi kweefayile ezininzi zeefayile ezifana ne- JPG ukuya kwi- PNG okanye kwi- GIF ukuya kwi- TIF .
I-Convert Command
Umyalelo wokuguqula usetyenziswa ukuguqula umfanekiso. Ifomathi ilandelayo:
guqula [inketho yokufakelwa] ifayile yefayile [okukhethwa kwiphumo] ifayile yefayile.
Indlela yokuvuselela umfanekiso
Ukuba uya kubandakanya umfanekiso kwiwebhsayithi kwaye ufuna ukuba ube sisayizi ethile uze ungasebenzisa i-CSS ukuze uhlalutye umfanekiso.
Eyona nto ingcono ukuba ulayishe umfanekiso njengomlinganiselo ochanekileyo kwindawo yokuqala uze uyifake kwiphepha.
Oku kunjalo umzekelo omnye nje ukuba kutheni ufuna ukutshintsha umfanekiso .
Ukutshintshisa umfanekiso usebenzisa umyalelo olandelayo
guqula i-imagename.jpg -resize ubukhulu be-new pictureame.jpg
Umzekelo, ukuguqula umfanekiso ube ngu-800x600 uza kusebenzisa umyalelo olandelayo:
guqula imagename.jpg -resize 800x600 entsha pictureame.jpg
Ukuba ngokuguqula kwimilinganiselo echaziweyo umlinganiselo wendawo uza kuhlaziywa umfanekiso uza kuhlaziywa kumlinganiselo osondeleyo.
Ukunyanzela ukuguqulwa ukuba kube bukhulu obuchanekileyo, sebenzisa umyalelo olandelayo:
guqula imagename.jpg -resize 800x600! new pictureame.jpg
Awunayo ukucacisa ukuphakama nobubanzi njengenxalenye yomyalelo wokuguqula.
Umzekelo, ukuba ufuna ububanzi bube ngu-800 kwaye awukhathalele ngokuphakama ungasebenzisa umyalelo olandelayo:
guqula imagename.jpg -resize 800 entsha pictureame.jpg
Ukuhlaziya umfanekiso ukuba ube ngumphakamo ocacileyo sebenzisa umyalelo olandelayo:
guqula umfanekiso, jpg-ulungise x600 newobrazame.jpg
Indlela yokuguqula ukusuka komnye umfanekiso wesithombe ukuya kwenye
Ukuba unayo ifayile yeJPG kwaye unqwenela ukuguqula kwi-PNG uze usebenzise umyalelo olandelayo:
guqula umfanekiso.jpg image.png
Unokudibanisa ifomathi ezininzi zeefayile ezahlukeneyo. Umzekelo
guqula umfanekiso.png image.gif
guqula umfanekiso.jpg image.bmp
guqula umfanekiso.gif image.tif
Indlela yokulungisa ubungakanani befayili yesithombe
Kukho iindlela ezininzi zokutshintsha ubungakanani befayili yomfanekiso wesithombe.
- Shintsha umlinganiselo wendlela (yenza kube mncinci)
- Shintsha ifayile yefayile
- Shintsha umgangatho wokunciphisa
Ukunciphisa ubukhulu bomfanekiso kuza kwenza ubungakanani befayili bube ncinane. Ukongeza, ukusebenzisa ifayile yefayile ebandakanya ukunyanzelisa okufana ne-JPG iya kukukunceda ukunciphisa ubukhulu befayile.
Ekugqibeleni ukulungiswa komgangatho kuya kwenza ukuba ubuncinane befayile befayile.
Amacandelo angaphambili angama-2 akhombisa indlela yokulungisa utshintsho kunye nohlobo lwefayile. Ukucinezela umfanekiso uzame umyalelo olandelayo:
guqula i-imagename.jpg -quality 90 newimage.jpg
Umgangatho uchazwe njengepesenti. Ixabiso elingaphantsi kwepesenti encinci yefayile yefayile kodwa ngokucacileyo umgangatho wokugqibela umgangatho awunjalo.
Indlela yokuguqula iMifanekiso
Ukuba uthathe isithombe kwi-portrait kodwa ufuna ukuba ube umfanekiso wesimo somhlaba ungatshintsha umfanekiso usebenzisa umyalelo olandelayo:
guqula imagename.jpg -rotate 90 newimage.jpg
Ungacacisa nayiphi na indawo yokujikeleza.
Umzekelo, zama oku:
guqula i-imagename.jpg -rotate 45 entshaimage.jpg
Guqula iiNgcaciso zoLwazi lweMilo
Kukho iindlela ezininzi zokukhetha umgca ongasetyenziswa kunye nomyalelo wokuguqula njengoko kuboniswe apha:
Izinketho zenziwa kwi-order order line. Naluphi na ukhetho olucacileyo kumgca womyalelo luhlala lusebenza ngokusetyenzwa kwezithombe ezilandelayo, de kube kusetyenziswe ukubonakala kwayo nayiphi na inketho okanye -noop . Ezinye iinketho zichaphazela kuphela ukuchithwa kwemifanekiso kunye nabanye kuphela ikhowudi. Ezi zilandelayo zingabonakala emva kweqela lokugqibela lemifanekiso yokufaka.
Ukufumana inkcazo ecacileyo yenketho nganye, funda i- ImageMagick .
