Kwinqaku elilandelayo siza kujonga ukuba sinokwenza njani jonga imethadatha yomfanekiso kwisiphelo seBuntu. Le datha yomfanekiso yingqokelela yolwazi malunga nemifanekiso efakwe kuyo okanye egcinwe kwifayile eyahlukileyo.
Xa imethadatha yongezwa kwimifanekiso imifanekiso ihlala ilandelwa, inqanda ukubiwa kwemixholo okanye ukusetyenziswa gwenxa. Nangona kunjalo, ukuba sinomdla, siya kuba nakho ukubonisana, silungise okanye sibasuse ngendlela elula.
Iindidi zemethadatha
Siza kufumana iintlobo ezintathu ezahlukeneyo ezinje:
- Imethadatha yobugcisa → Olu hlobo lweemethadatha ngokubanzi lubandakanya ulwazi lobuchwephesha malunga nomfanekiso, njengeenkcukacha zekhamera, i-DPI, isantya se-shutter, ubungakanani befayile, isoftware esetyenzisiweyo ukwenza umfanekiso, umhla kunye nexesha eyabanjwa ngalo okanye ukwenza umfanekiso, ifomathi yomfanekiso kunye ezinye iinkcukacha. Imethadatha yobuchwephesha iveliswa ikakhulu zizixhobo ezithatha umfanekiso.
- Imethadatha echazayo → Ezi ifakwe ngesandla ngumfoti. Umnini womfanekiso angabongeza ngesandla usebenzisa nayiphi na isoftware yangaphandle enje nge-GIMP okanye iPhotohop. Oku kuhlala kubandakanya ulwazi olufana nesihloko somfanekiso, indawo, igama lomfoti, kunye nezimvo. Imethadatha echazayo ziluncedo kakhulu xa ukhangela okanye ukhathaza imifanekiso ngokulula nangokukhawuleza.
- Imethadatha yolawulo → Ezi ziqulathe Ukuchonga umnini kunye neenkcukacha zonxibelelwano, ilayisensi, ilungelo lokushicilela kunye nokusetyenziswa kwemifanekiso.
Jonga imethadatha yomfanekiso ukusuka kwisiphelo seBuntu
KwiGnu / Linux sinokufumana ezininzi izixhobo zokufunda okanye zokuguqula imethadatha yomfanekiso. Emva koko siza kubona izixhobo zomgca ezintathu zokuya kuthi sikwazi ukufunda ngazo zonke iinkcukacha zomfanekiso.
Sebenzisa i-ImageMagick
Ukuchonga sisixhobo esifakwe kwi-ImageMagick esinokuthi siqwalasele ngayo imethadatha yomfanekiso. Siza kuyifumana le software ifumaneke kwiindawo zokugcina zeGnu / Linux. Ukuba sisebenzisa iDebian, Ubuntu okanye iLinux Mint, konke ekufuneka sikwenzile ukuvula i-terminal (Ctrl + Alt + T) kwaye usebenzise lo myalelo ulandelayo ukufaka i-ImageMagick:
sudo apt install imagemagick
Emva kofakelo, ngoku sinokukhangela kwimethadatha yomfanekiso. Ukwenza oku, kwisiphelo sendlela kuya kufuneka wenze kuphela:
identify -verbose imagen.jpg
Lo myalelo Izakusibonisa imveliso eneenkcukacha zemetadata yomfanekiso onikiweyo. Kwimeko yokufuna jonga kuphela iinkcukacha ezisisiseko, Kuya kufuneka sisuse ukhetho -ingxaki. Umyalelo uya kuba ngolu hlobo lulandelayo:
identify imagen.jpg
Iyafumaneka Iinkcukacha ezithe kratya kumaphepha endoda:
man identify
Sebenzisa isixhobo se-Exif
I-Exif sisixhobo somgca wokuyalela bonisa kwaye utshintshe Idatha ye-Exif yomfanekiso. Exif kuthetha Ifomathi yefayile yefayile eguqukayo, eyifayile yomfanekiso ebhalwe kwisixhobo sethu sokugcina ngalo lonke ixesha sithatha ifoto kunye ne-smartphone okanye ikhamera.
Idatha ye-Exif ibandakanya iinkcukacha ezifana nomhla kunye nexesha leefoto, useto lwekhamera, indawo ekuyo, ilayisensi kunye nolwazi lwamalungelo obunini, njl. Esi sixhobo iyafumaneka koovimba abagqibeleleyo kwiDebian nakwiziphumo zayo ezinje ngeBuntu. Ukuyifaka, kuya kufuneka uchwetheze kwisiphelo sendlela (Ctrl + Alt + T) kwaye uthayiphe:
sudo apt install exif
Nje ukuba esi sixhobo sifakiwe, sinokwenza ukuba sisebenze ngokwenza kwisiphelo esinye:
exif imagen.jpg
I-Exif iya kuvelisa imveliso epheleleyo kwifomathi yekholamu ebonisiweyo njengoko ubona kwisikrini sangaphambili. Kuba Fumana iinkcukacha ezithe kratya ngesi sixhobo, bona amaphepha endoda ahambelanayo:
man exif
Sebenzisa umyalelo wefayile
Siya kuba nakho uku sebenzisa umyalelo wefayile ukujonga imethadatha yomfanekiso. Kwisiphelo kuya kufuneka sibhale kuphela:
file imagen.jpg
Umyalelo ifayile ayinakho ukhetho lokusibonisa iziphumo ezineenkcukacha njengemiyalelo engentla. Kuprinta kuphela imethadatha esisiseko.
Ukuba ufuna bona ulwazi malunga nalo myalelo, ungayenza kumaphepha endoda:
man file
