Extension

Il est possible de créer ses propres extension, notamment avec Python et ImageMagic.

Icon Export

Cette extension crée un fichier icone dont l'extension est .ico et dont les caractéristiques sont les tailles suivantes : 256x256, 128x128, 64x64, 48x48, 32x32, 24x24 et 16x16

Site :

Pour l'installation de l'extension :

  • télécharger l'archive icon-export-main_eGEB7zn.zip depuis le site ;
  • depuis Inkscape, menu Extensions > Gérer les extensions... :
    • onglet "Install Packages",
    • bouton de sélection de paquet,
    • sélectionner l'archive précédemment téléchargée,
    • bouton "Ouvrir",
  • redémarrer Inkscape.

Une fois l'installation terminée, les fichiers correspondants à l'extension sont dans le dossier suivants :

  • C:\Users\compteutilisateur\AppData\Roaming\inkscape\extensions\inklinea.icon_export\

Après redémarrage d'Inkscape, la création d'icone se fait par :

  • Extensions > Exporter > Icon Export...
  • une fenêtre d'options est proposée.

Exemple de génération PDF et quadricouleur CMJN

Exporter en PDF et quadricouleur CMJN (CMYK) :

L'utilisation de cette extension de fait par l'option d'enregistrement : menu Fichier > Enregistrer sous... et type de fichier PDF CMYK (*.pdf)
