Hier hilft der Dialog »Ausrichten und Verteilen« (<flowSpan font-weight="bold">Strg+Umschalt+A</flowSpan>). Wählen Sie alle Quadrate aus (mit <flowSpan font-weight="bold">Umschalt+Klick</flowSpan> oder dem Gummiband), öffnen Sie dann den Dialog und drücken »Zentren horizontal ausrichten«. Danach benutzen Sie »Horizontale Abstände zwischen Objekten ausgleichen« (lesen Sie die Tooltips der Schaltflächen). Die Objekte sind jetzt gleichmäßig ausgerichtet und verteilt.

(So funktioniert »Klicken und Ziehen« nunmal – es wählt das (oberste) Objekt unter dem Mauszeiger, dann verschiebt es das gewählte Objekt). Um Inkscape mitzuteilen, das man das <flowSpan font-style="italic">gerade gewählte</flowSpan> Objekt verschieben will, und nicht etwa ein anderes auswählen möchte, benutzt man <flowSpan font-weight="bold">Alt+Ziehen</flowSpan>. Das verschiebt das aktuell markierte Objekt, egal wo man mit der Maus hinklickt.</flowDiv>

À chaque étape, l&apos;algorithme a le choix d&apos;explorer les opérations que cette représentation propose. Certaines de ces représentations intermédiaires ont un aspect visuel correct (comme une cellule remodelée dans un graphe de Voronoï), d&apos;autres pas (comme un graphe de similitude). Pendant le développement de libdepixelize, les utilisateurs n&apos;ont eu de cesse de demander à ce qu&apos;il soit possible d&apos;exporter ces étapes intermédiaires à partir de la bibliothèque, et l&apos;auteur original a exaucé leurs vœux.</flowDiv>

Aucune courbe n&apos;est créée et l&apos;image est toujours composée de lignes droites. La différence peut être observée en agrandissant l&apos;image. Précédemment, les pixels ne pouvaient pas partager de bord avec un voisin en diagonale, même si il ce voisin faisait partie de la même fonction. Mais maintenant (grâce à un graphe de similitude de couleur et l&apos;heuristique que vous pouvez ajuster pour obtenir un meilleur résultat), il est possible de faire en sorte que deux cellules diagonales partagent un bord (auparavant seul un sommet pouvait être partagé entre deux voisins de ce type).</flowDiv>

Notez qu&apos;un résultat identique est obtenu avec la dernière image, qui utilise pour sa part l&apos;heuristique Pixels clairsemés. Une différence vient du fait que sa force est plus modérée et qu&apos;elle ne donne de fortes valeurs à son vote que si la conservation des connexions est vraiment importante. La définition de modéré est ici basée sur l&apos;intuition humaine, vue la base de pixels analysée. Une autre différence est que cette heuristique ne peut pas prendre de décision lorsque les connexions assemblent de grands blocs plutôt que des longues courbes (imaginez un jeu d&apos;échecs).</flowDiv>

   <flowDiv xml:space="preserve">Pour le troisième essai (image du bas), nous avons activé l&apos;heuristique Pixels clairsemés. Cette heuristique tente de converser les courbes avec une couleur de premier plan connectées. Pour déterminer cette couleur, l&apos;heuristique analyse une fenêtre contenant les pixels voisins de la courbe conflictuelle. Vous pouvez ainsi non seulement ajuster sa force, mais également la taille de la fenêtre de pixels à analyser. Gardez à l&apos;esprit que l&apos;augmentation de cette fenêtre augmente aussi la force du vote, et qu&apos;il sera peut-être nécessaire de rééquilibrer en modifiant le multiplicateur. L&apos;auteur original de libdepixelize estime cette heuristique trop gourmande et conseille une valeur de 0,25 pour le multiplicateur.</flowDiv>

   <flowDiv xml:space="preserve">Cette option utilise l&apos;algorithme de détection des arêtes énoncé par J. Canny, afin de trouver rapidement des isoclines de contraste similaire. Cela produit une image intermédiaire qui ressemble moins à l&apos;image originale que le résultat d&apos;un seuil de luminosité mais qui contient souvent des courbes qui seraient ignorées autrement. Le seuil à régler ici (de 0,0 à 1,0) ajuste le seuil de luminosité afin de déterminer si un pixel adjacent à une courbe de contraste doit être inclus dans le résultat. Le réglage permet d&apos;ajuster l&apos;obscurité ou l&apos;épaisseur des arêtes du résultat.</flowDiv>
