Diese Frage ist eine Erweiterung meinerletzte FrageUndeine Antwortvon @frougon.
Ich habe den Code der Antwort ein wenig bearbeitet, um ihn meinen Bedürfnissen anzupassen, aber die wichtigen Teile bleiben erhalten (so hoffe ich).
Ich habe imagesAltund erstellt questionpictureAlt, wodurch die enumerateUmgebung entfernt wird und ich meine Tikzpictures direkt in mein Dokument einfügen kann, ohne dass eine Aufzählung erforderlich ist. Es funktioniert bisher ziemlich gut.
Das Problem, das ich habe, ist, dass die Tikz-Bilder nicht ganz auf der Seite zentriert sind. Ich bin mir nicht sicher, ob das an den Änderungen liegt, die ich an Frougons Antworten vorgenommen habe, oder ob es etwas mit dem tcolorboxPaket zu tun hat, das ich verwende (ich glaube nicht, dass das der Fall ist), oder etwas anderes.
Unten ist mein Code/meine Ausgabe, wo ich farbige Linien eingefügt habe, wobei jede Farblinie gleich lang ist, um zu zeigen, dass die Dinge nicht richtig zentriert sind.

Antwort1
Bitte beachten Sie die Stellen, die ich <---im untenstehenden Code mit markiert habe. Sie haben ein paar falsche Leerzeichen eingefügt, gesetzt \fboxruleauf0pt naches wurde für eine Berechnung mit einem anderen Wert verwendet (Berechnung in \AfterEndEnvironment{questionpictureAlt}{...}). Ich bin mit der Namensänderung von „Paket“ in nur nicht einverstanden form, da die Wahrscheinlichkeit sehr hoch ist, dass es jetzt oder in Zukunft zu Kollisionen mit einem anderen Paket kommt (im von mir bereitgestellten Code habe ich das „Paket“ ryanjformgenau so genannt, um Sie vor solchen Kollisionen zu schützen). Außerdem wurde eines der von \letIhnen erstellten Pakete zerstört \form@start@question@picture... weshalb Sie das Durcheinander \let\questionpictureAlt\form@start@question@picture(beachten Sie das fehlende Alt) in machen mussten \newenvironment{imagesAlt}{...}{...}.
Ein weiterer Punkt ist, dass ich die Verwendung imagesAltmit einem leeren sehr unnatürlich finde minipage, da dies die einzige Situation ist, in der dieses minipagenicht die in seinem Argument angegebene Breite einnimmt. Die minipageBreite in meiner choicesUmgebung wurde so berechnet, dass minipageplus das Bild in - \fcolorboxgenau einnimmt \linewidth. Die Verwendung von diesem mit einem leeren minipage, das einen Sonderfall auslöst, der seine Breite zerstört, widerspricht also der erwarteten Verwendung der choicesUmgebung, auf der imagesAltbasiert. Wenn Sie kein möchten minipage, warum führen Sie dann die Breitenberechnungen durch? Sie erfüllen keinen Zweck, wenn kein vorhanden ist minipage. Entfernen Sie in einem solchen Fall einfach das minipageaus der Umgebungsdefinition, die ungenutzten Breitenberechnungen, setzen Sie das ein \fcolorboxund fertig.
Ebenso imagesAltnimmt since konzeptgemäß eine volle Zeilenbreite ein, sobald Sie ein druckbares Zeichen zwischen \end{questionpictureAlt}und dem folgenden einfügen \end{imagesAlt}, und umschließt es imagesAltinnerhalb einer centerUmgebung, um dasBilddas normalerweise bündig mit dem rechten Rand abschließen sollte, ist eine sehr seltsame Technik. Wenn Sie imagesAltnur das enthalten würden \fcolorbox, wäre das meiner bescheidenen Meinung nach viel natürlicher.
Entschuldigen Sie, wenn ich negativ klinge, aber das alles noch einmal zu lesen hat lange gedauert, es ist schon spät und diese seltsamen Verwendungsweisen des aus meiner choicesUmgebung abgeleiteten Codes haben mich sozusagen verärgert (mir fehlen die richtigen Worte für Englisch – Sie haben mich „umgebracht“! :-) Der folgende Code behebt die im ersten Absatz dieser Antwort sowie in Ihrer documentUmgebung genannten Probleme (am linken Rand beginnen, zentrieren usw.):
