Ukuhlela nokuphinda uthinte izithombe zedijithali nge-Imagemagick

I-Imagemagick i-suite yama-softwares wokudala, ukuhlela nokuqamba izithombe.

Le suite yesoftware yakhiwe yiqembu lezinhlelo zokuhlela izithombe zisuka kulayini womyalo ngaphandle kwesidingo sanoma yiluphi uhlelo lokusebenza lwezithombe, olumele inzuzo enkulu lapho kuthuthukiswa imibhalo ngemiyalo ethile yokuguqula noma ukuguqula isithombe esithile,
imiyalo iboniswa ngezansi:

Imiyalo ethandwa kakhulu yile bona, ukuguqula y hambisa; owokuqala ukukhomba imininingwane yesithombe njengosayizi waso, isilinganiso saso esincane phakathi kwabanye; owesibili ukuguqula isithombe sibe sesinye, owokugcina akaziwa kakhulu kepha wasetshenziselwa ukuguqula isithombe ngqo hhayi ukwenza ikhophi yaso.

Manje uma okufunayo ukuguqula iqembu lezithombe libe elinye ifomethi, kunconywa ukuthi usebenzise hambisa Ngokulandelayo:

mogrify -format png /carpeta-de-imagenes/*

Ukwazi amafomethi ahambisana nalolu hlelo singasebenzisa umyalo olandelayo:

mogrify -list format

Ukuguqula nokuhlanganisa kungasetshenziselwa umsebenzi ofanayo, ukhiye ukuthi ukuguqula kufanele kubhale isithombe ngaphandle kwesokuqala futhi mogrify akuxhomekile ekutheni kuguqulwe kusuka kufomethi eyodwa kuya kwenye.

Ungahlala ufunda ngemisebenzi yalezi zinhlelo ngokufunda amafayela osizo

Manje ake sithi sidinga ukucindezela isithombe se-jpg esisanda kuthathwa kwikhamera enesisindo esingaba ngu-2 mb noma ngaphezulu futhi sifuna ukuthi sinciphise isisindo sayo nge-MB ngaphandle kokunciphisa ikhwalithi noma usayizi shazi, ake sibone isibonelo:

mogrify -compress jpeg -qualit 80% /imagen/a/modificar

Amaphesenti akhombisa izinga lokuqonda elingasuka ku-0 liye ku-100.

Ngokukhethwa kukho -khulisa usayizi singashintsha usayizi wesithombe uma siyisibonelo esikhulu kakhulu:

mogrify -resize 1024x768 /imagen/a/modificar

Ngakolunye uhlangothi sinokungenisa okuzosivumela ukuthi sithathe isithombe-skrini sesikrini kunoma iyiphi ifomethi yesithombe esekelwayo, isibonelo:

Ukuthatha iskrini esigcwele

import -window root /detino/imagen.jpg

Khetha indawo ongayishutha

import /detino/imagen.jpg

Uma sifuna ukwenza isithombe se-animated .gif ngokulandelana kwezithombe esizilungisile, singasebenzisa umyalo wokuguqula ngokulandelayo:

convert /carpeta/de/imagenes/* /carpeta/alida/fichero.gif

Umyalo wokubonisa uzovula isithombe kube sengathi yisibukeli sesithombe esizosivumela ukuthi senze imiphumela ngokungeza umbhalo, phakathi kwezinye izinto, ngenzuzo yokuthi sizobona ukuthi isithombe sibukeka kanjani kunqubo, esizoba yiyo sikwazi ukwazisa imiphumela ehlukile esingayisebenzisa, kusuka kumthelela omubi njengokungeza amafreyimu, ukuguqula isithombe, njll.
