Ngineqiniso lokuthi ngesinye isikhathi uzobe wenze ukuqhathaniswa kwezithombe ezimbili komunye umdlalo noma inselelo lapho bekufanele uthole inani elithile lokwehluka. Kulolu hlobo lomsebenzi bakunikeza okungenani izithombe ezimbili ezibonakala zifana futhi kufanele uthole umehluko.
Kulolu hlobo lomsebenzi kukhona uhlelo lokusebenza lokho kuzokusiza ukuthola lezi zinhlobo zokwehluka. I-Diffimg kuyinto isicelo kubhalwe mahhala ku-Qt nomthombo ovulekile enesibopho sokubona ngamehlo nokuthola umehluko phakathi kwezithombe ezimbili ngoba kwenza ukuqhathanisa phakathi kwazo zombili.
Lolu hlelo lokusebenza uphethe ukumaka lokho kwehluka okutholayo phakathi kwezithombe ezingaqhathaniswa nezingabonakali ekuqaleni kokubona.
Enye yezinsiza ezisemqoka zaleli thuluzi ukuqinisekiswa kokulungiswa ezithombeni, lapho isebenzisa khona amamethrikhi amaningi angasetshenziswa ukubala umehluko phakathi kwazo.
Ngokuyinhloko okwenzayo hlukana ukwenza i-pixel ngokuhlola kwe-pixel futhi ubonise umsebenzisi indawo lapho athola khona umehluko endaweni ethile yamaphikseli phakathi kwezithombe ezimbili okufanele azihlole.
Amanye alawa masheke ayabalwa futhi nezikhundla lapho amaphikseli ehlukile akhonjiswa njengesifihla-mbala sombala.
Imodi yokuqhathanisa isithombe ingakhombisa imbondela yesifi ebomvu ekhombisa ushintsho oluncane noma okuphuzi ukugqamisa umehluko omkhulu phakathi kwalezi zithombe ezimbili.
I-Diffimg Ine-interface enembile futhi esebenziseka kalula, isebenzisa i-OpenCV njenge-backend ezisekela ngayo ukuze ikwazi ukufunda nokuqhathanisa izithombe ezingama-8/16/24/32 ngaphandle kwenkinga.
Okuwukuphela kokubi kulolu hlelo ukuthi akusekeli isiteshi se-alpha. Ngaphezu kwalokho, ingafunda amafomethi wesithombe ayisisekelo njenge-BMP, i-PNG, i-JPG, kepha futhi ne-Tiff ne-OpenExR.
I-DiffImg iyi-cross-platform application ngoba njengoba kushiwo ibhalwe ku-Qt ngakho-ke isebenza ku-Windows ne-Linux.
Ungayifaka kanjani i-diffimg ku-Ubuntu 18.04 nakwezokuphuma?
Uma ufuna ukufaka leli thuluzi elipholile lokuhlola isithombe kusistimu yakho, kumele wenze lezi zinyathelo ezilandelayo.
Kufanele bavule i-terminal Ctrl + Alt + T futhi kuyo sizobhala umyalo olandelayo ukufaka indawo yokugcina ohlelweni lwethu:
sudo add-apt-repository ppa:dhor/myway
Uma lokhu sekwenziwe, sizovuselela uhlu lwethu lwezinqolobane ngalo myalo:
sudo apt update
Ekugcineni sifaka uhlelo lokusebenza ngomyalo olandelayo:
sudo apt-get install diffimg
Ungayifaka kanjani i-diffimg kusuka ku-deb package ku-Ubuntu 18.04 nakwezokuphuma?
Uma ungafuni ukufaka indawo yokugcina ohlwini lwakho, sinenketho yokufaka lolu hlelo kusuka kwiphakethe lesikweletu.
Kulokhu ake silande uhlelo lokusebenza funa isixhumanisi esilandelayo. Uma lokhu sekwenziwe, singakwazi ukufaka uhlelo lokusebenza nomphathi wohlelo esikuthandayo.
Noma futhi uma uthanda, ungayifaka kusuka ku-terminal ngomyalo olandelayo:
sudo dpkg -i diffimg_2.2.0-1dhor~trusty_amd64.deb
Futhi ngomumo ngalo sizofaka isicelo.
Uma kwenzeka unezinkinga ngokuthembela singakuxazulula ngalo myalo:
sudo apt-get install -f
Ungayisebenzisa kanjani i-diffimg?
Ukuqala ukusebenzisa lolu hlelo lokusebenza, kufanele siqale silivule. Ngalokhu sizokufuna kwimenyu yethu yezinhlelo zokusebenza ukuyiqhuba.
Uma sesingaphakathi, kuzofanele sikhethe kuphela izithombe esizoziqhathanisa ne-diffimg.
Kulokhu ake uchofoze isithonjana sefolda okusemenyu yohlelo lokusebenza futhi sizokhetha izithombe ozoziqhathanisa, lapho owokuqala kuzoba isithombe sokuqala bese owesibili kube yilowo ozosetshenziswa ukuhlola umehluko.
Lapho lokhu sekwenziwe, ngokuya ngesisindo sezithombe okufanele siqhathaniswe, kungathatha isikhashana ukuthi uhlelo lokusebenza lusebenze.
Ibhokisi lengxoxo lizovuleka futhi okucacisa izinga lokufana phakathi kwazo zombili izithombe nephesenti lokungafani ngamaphikseli, phakathi kolunye ulwazi.
Uma wazi noma yiluphi olunye uhlelo lokusebenza olufana nalokhu, unganqikazi ukuluhlanganyela nathi kumazwana abekiwe.
Angikwazanga ukuyifaka ku-Ubuntu 18.04. Akudingeki ukuthi ulinde iphakethe le-Bionic ukuthi liphume? Ngibona uXenial noTrusty kuphela.
