[WPF] Génération d'un document XPS multipage
Génération d'un document XPS multipage en WPF
Préambule
Ce tutoriel va présenter la génération de documents XPS multipages.
Nous allons voir comment générer un document multipages sous diverses formats (A0 ... A10, etc...)
La plupart des standards connus sont intégrés (la source contient 2 standards de plus que la version papier).
Le tutoriel est très simple. La seule chose qui soit longue est la création des standards...
Introduction
Lorsque nous développons une application, il arrive parfois que l'on ait besoin de faire des impressions de nos contrôles présents à l'écran ou pour tout autre chose.
Dans le projet que je réécris en WPF, l'utilisateur doit placer les produits que le magasin vend sur les rayons de sorte que les afficheurs digitaux affichent les bonnes informations. Il me fallait donc laisser à l'utilisateur le choix de garder une trace physique de ces informations. Utilisant WPF, il m'est apparu facile de générer ce document imprimable en XPS. Nous verrons comment générer un fichier xps de manière « standard » et une autre manière plus abouti.
Génération d'un document XPS par les classes de base
WPF fournit quelques classes pour la génération de documents XPS. Nous avons :
- Package : ouvre un flux utilisable par XpsDocument.
- XpsDocument : Permet de créer le document XPS.
- XpsDocumentWriter : Permet d'écrire les objets dans le document XPS.
Ecrire des objets dans le document XPS est extrêmement simple avec cette méthode, voici un exemple :
static public void WriteVisuals(string filename, IEnumerable<Visual> visuals)
{
Package package = FileStream.Open(filename, FileMode.Create, FileAccess.Write);
XpsDocument xDoc = new XpsDocument(package);
XpsDocumentWriter writer = XpsDocument.CreateXpsDocumentWriter(xDoc);
foreach(Visual visual in visuals)
writer.Write(visual);
package.Close();
}
Comme vous le voyez, il s'agit d'une méthode simple, on ouvre un package avec le nom du fichier passé en paramètre. Ensuite on crée le document XPS et enfin on le remplit.
Simple et rapide, n'est-ce pas ? Cependant, mes essais m'ont conduit à un grave problème : le fichier généré est toujours d'une page.
Mes recherches m'ont conduit à créer le multipage de manière manuelle. Ce que j'ai donc fait mais avec des modifications bienvenues.
Génération de documents XPS multipages
Dans cette partie, nous allons créer notre document en multipages en utilisant un FixedDocument. Le seul inconvénient de cette classe est que l'on ne peut pas choisir l'emplacement de rendu de ses objets. Néanmoins avec ce que nous allons voir, il s'agit d'un moindre mal.
En premier lieu créons une bibliothèque de classes nommé XpsGenerator.
Une fois cela fait, cliquez-droit sur `References' et ajoutez ces assemblies :
ReachFramework
System.Printing
Ces deux assemblies vont nous permettre d'avoir accès à l'espace de noms Xps.
Puis ajoutez aussi cette assembly pour pouvoir avoir accès aux classes FixedDocument, DocumentViewer et UIElement.
WindowsBase
PresentationCore
PresentationFramework
Maintenant lorsque nous allons vouloir imprimer nos fichiers il pourrait être utile de choisir la « taille » du papier à savoir A0, A1, ..., A10. Et pour pouvoir choisir une taille définie à la feuille (par exemple 101 mm x 23 cm), il faudrait que nous puissions avoir une routine qui calcule le nombre de pixels à notre place. Commençons donc :
En premier, nous allons créer un fichier qui contiendra juste une propriété permettant de connaitre la valeur de calcul. (Cette valeur sera représentée en pixels).
Nommez ce fichier RenderFormat et remplissez-le comme ceci :
namespace XpsGenerator
{
/// <summary>
/// Format to render.
/// </summary>
sealed public class RenderFormat
{
#region Property
/// <summary>
/// Gets the value of the rendered format.
/// </summary>
public double Value
{
get;
private set;
}
#endregion
#region Constructor
/// <summary>
/// Instantiates a new rendering format.
/// </summary>
/// <param name="value">Value of the format.</param>
internal RenderFormat(double value)
{
Value = value;
}
#endregion
}
}
Ensuite, créez un fichier RenderFormats qui contiendra les propriétés de RenderFormat que nous aurons définis :
Pixel : Contient la valeur d'un pixel
Inch : Contient la valeur d'un pouce (en pixels)
Centimeter : Contient la valeur d'un centimètre (en pixel)
Millimeter : Contient la valeur d'un millimètre (en pixel)
Point : Contient la valeur d'un point (en pixel)
Un pixel aura la valeur par défaut 1.
Un pouce aura la valeur par défaut 96. (un pouce = 96 pixels)
Un centimètre aura la valeur par défaut 37.7952.... (un centimètre = 96 / 2.54 pixels)
Un millimètre aura la valeur par défaut 3.77952... (un millimètre = 1 / 10 cm)
Un point aura la valeur par défaut 1.33 (un point = 96 / 72 pixels)
Ces valeurs peuvent être trouvées sur la MSDN ici
Le fichier est donc rempli comme ceci :
namespace XpsGenerator
{
/// <summary>
/// Represents a list of rendered format.
/// </summary>
static public class RenderFormats
{
#region Fields
/// <summary>
/// Represents a pixel.
/// </summary>
static private readonly RenderFormat pixel;
/// <summary>
/// Represents an inch.
/// </summary>
static private readonly RenderFormat inch;
/// <summary>
/// Represents a centimeter.
/// </summary>
static private readonly RenderFormat centimeter;
/// <summary>
/// Represents a point.
/// </summary>
static private readonly RenderFormat point;
/// <summary>
/// Represents a milimeter.
/// </summary>
static private readonly RenderFormat milimeter;
#endregion
#region Properties
/// <summary>
/// Gets the format of a pixel. (1 px)
/// </summary>
static public RenderFormat Pixel
{
get { return pixel; }
}
/// <summary>
/// Gets the format of an inch. (1in = 96 px)
/// </summary>
static public RenderFormat Inch
{
get { return inch; }
}
/// <summary>
/// Gets the format of a centimeter. (1cm = 96.0 / 2.54 px)
/// </summary>
static public RenderFormat Centimeter
{
get { return centimeter; }
}
/// <summary>
/// Gets the format of a milimeter. (1mm = 0.1 cm)
/// </summary>
static public RenderFormat Milimeter
{
get { return milimeter; }
}
/// <summary>
/// Gets the format of a point. (1pt = 96.0 / 72.0 px)
/// </summary>
static public RenderFormat Point
{
get { return point; }
}
#endregion
#region Constructor
/// <summary>
/// Instantiates each format.
/// </summary>
static RenderFormats()
{
pixel = new RenderFormat(1.0);
inch = new RenderFormat(96.0);
centimeter = new RenderFormat(96.0 / 2.54);
milimeter = new RenderFormat(0.1 * (96.0 / 2.54));
point = new RenderFormat(96.0 / 72.0);
}
#endregion
}
}
A présent que nous avons nos « convertisseurs » nous pouvons nous atteler à la création de nos feuilles. Nos feuilles pourront être rendues de 2 façons :
Portrait
Paysage
Créez donc un nouveau fichier nommé SheetOrientation et remplissez-le comme ceci :
namespace XpsGenerator
{
/// <summary>
/// Orientation of the sheet.
/// </summary>
public enum SheetOrientation
{
/// <summary>
/// Portrait orientation.
/// </summary>
Portrait,
/// <summary>
/// Landscape orientation.
/// </summary>
Landscape
}
}
Ensuite nous allons créer nos feuilles. Pour cela, il nous faudra créer une classe SheetFormat, qui contiendra une propriété Width de type double représentant la longueur de notre feuille, et une propriété Height de type double représentant la hauteur de notre feuille. Pour plus de flexibilité le constructeur est laissé en type publique, dès fois qu'il y'ait besoin d'imprimer des objets sur des feuilles non standardisés.
Maintenant, créez un fichier SheetFormat et remplissez-le comme ceci :
namespace XpsGenerator
{
/// <summary>
/// Represents a format of a sheet.
/// </summary>
sealed public class SheetFormat
{
#region Properties
/// <summary>
/// Gets the width of the sheet.
/// </summary>
public double Width
{
get;
private set;
}
/// <summary>
/// Gets the height of the sheet.
/// </summary>
public double Height
{
get;
private set;
}
#endregion
#region Constructor
/// <summary>
/// Instantiates a new sheet format.
/// </summary>
/// <param name="width">Width of the sheet.</param>
/// <param name="height">Height of the sheet.</param>
/// <param name="heightRenderFormat">RenderFormat to use for the height of the sheet.</param>
/// <param name="widthRenderFormat">RenderFormat to use for the width of the sheet.</param>
public SheetFormat(double width, double height, RenderFormat widthRenderFormat, RenderFormat heightRenderFormat)
{
Width = width * widthRenderFormat.Value;
Height = height * heightRenderFormat.Value;
}
/// <summary>
/// Instantiates a new sheet format.
/// </summary>
/// <param name="width">Width of the sheet.</param>
/// <param name="height">Height of the sheet.</param>
/// <param name="renderFormat">RenderFormat to use for width and height of the sheet.</param>
public SheetFormat(double width, double height, RenderFormat renderFormat)
: this(width, height, renderFormat, renderFormat)
{ }
/// <summary>
/// Instantiates a new sheet format.
/// The rendering format is in milimeter mode.
/// </summary>
/// <param name="width">Width of the sheet.</param>
/// <param name="height">Height of the sheet.</param>
public SheetFormat(double width, double height)
: this(width, height, RenderFormats.Milimeter)
{ }
#endregion
}
}
Ici, nous restons flexible nous autorisons la création de feuilles dont la largeur et la hauteur souhaité ne sont pas dans le même format. Nous autorisons aussi la création de feuilles dont les dimensions ont le même format et enfin nous autorisons la création de feuilles au format millimétré.
Un avantage certain, lorsque nous souhaiterons imprimer nos feuilles en utilisant des rames standards (A3, A4, A5, ...), serait de posséder en interne les formats de fichiers standards.
Ce tableau les récapitule (ici, seulement les classes A à E sont représentées au format millimétré):
| CLASSE A | CLASSE B | CLASSE C | CLASSE D | CLASSE E | |
|---|---|---|---|---|---|
| 0 | 841 x 1189 | 1000 x 1414 | 917 x 1297 | ||
| 1 | 594 x 841 | 707 x 1000 | 648 x 917 | 779 x 545 | |
| 2 | 420 x 594 | 500 x 707 | 458 x 648 | 545 x 385 | |
| 3 | 297 x 420 | 353 x 500 | 324 x 458 | 385 x 272 | 560 x 400 |
| 4 | 210 x 297 | 250 x 353 | 229 x 324 | 272 x 192 | 400 x 280 |
| 5 | 148 x 210 | 176 x 250 | 126 x 229 | 192 x 136 | 280 x 200 |
| 6 | 105 x 148 | 125 x 176 | 114 x 126 | 136 x 96 | 200 x 140 |
| 7 | 74 x 105 | 88 x 125 | 81 x 114 | 96 x 78 | |
| 8 | 52 x 74 | 62 x 88 | 57 x 81 | ||
| 9 | 37 x 52 | 44 x 62 | 40 x 57 | ||
| 10 | 26 x 37 | 31 x 44 | 28 x 40 |

Maintenant créez un fichier SheetFormats qui contiendra toutes les standardisations fournit par Wikipédia. (De la classe A à la classe E, puis les normes françaises et Américaines).
Le fichier devient donc :

Tadaa, très long mais au moins on a une bonne base pour la création de documents.
La dernière étape consiste à écrire une classe permettant de générer un document xps multipages. Exceptionnellement simple grâce à la classe FixedDocument.
Créez un ultime fichier nommé FixedDocumentHelper.
Ajoutez-y les directives suivantes :
#region USING Directives using System; using System.IO; using System.IO.Packaging; using System.Windows; using System.Windows.Controls; using System.Windows.Documents; using System.Windows.Markup; using System.Windows.Xps; using System.Windows.Xps.Packaging; #endregion
Ensuite dans la classe (qualifiez-là aussi de sealed), créez une variable locale nommée fixedDocument de type FixedDocument.
#region Fields /// <summary> /// Represents the document to use to store our multipages. /// </summary> private FixedDocument fixedDocument; #endregion
Ensuite créez le constructeur instanciant ce document.
#region Constructor
/// <summary>
/// Instantiates the fixed document.
/// </summary>
public FixedDocumentHelper()
{
fixedDocument = new FixedDocument();
}
#endregion
Ensuite nous allons créer diverses méthodes pour ajouter nos pages dans le document. Comment allons-nous ajouter nos objets dans la feuille ? En premier on doit définir la taille de la feuille puis sa méthode de rendu (pixel, pouce, centimètre, millimètre et point), puis l'objet UIElement à injecter dans la feuille. Un fixed document prend en « paramètre » un PageContent. Le PageContent prendra en « paramètre » un FixedPage. Et ce FixedPage ne peut avoir en contenu qu'un type UIElement.
En premier lieu il faut créer notre PageContent puis notre FixedPAge. Ensuite on met en page la taille de la FixedPage créée en manipulant ses propriétés Width et Height.
Ensuite nous ajoutons notre contenu dans le fixedpage, puis nous ajoutons notrefixed page dans notre pageContent et enfin nous ajoutons notre pageContent dans le fixed document.
Attention on n'ajoute pas un contenu dans un PageContent comme ça, il faut passer par un cast explicite en IAddChild.
Donc dans notre code, cela donne :
/// <summary>
/// Add a page into the fixed document.
/// </summary>
/// <param name="width">Width of the page.</param>
/// <param name="height">Height of the page.</param>
/// <param name="renderFormatWidth">Device to use to render the width of the page.</param>
/// <param name="renderFormatHeight">Device to use to render the height of the page.</param>
/// <param name="contentPage">UI element to add as content of the page.</param>
public void AddPage(double width, double height, RenderFormat renderFormatWidth, RenderFormat renderFormatHeight, UIElement contentPage)
{
PageContent pageContent = new PageContent();
FixedPage fixedPage = new FixedPage();
fixedPage.Width = width * renderFormatWidth.Value;
fixedPage.Height = height * renderFormatHeight.Value;
fixedPage.Children.Add(contentPage);
((IAddChild)pageContent).AddChild(fixedPage);
fixedDocument.Pages.Add(pageContent);
}
Maintenant il nous faut une autre méthode qui uniformisera le format de rendu pour la hauteur et la largeur du document.
/// <summary>
/// Add a page into the fixed document.
/// </summary>
/// <param name="width">Width of the page.</param>
/// <param name="height">Height of the page.</param>
/// <param name="renderFormat">Device to use to render the width and the height of the page.</param>
/// <param name="contentPage">UI element to add as content of the page.</param>
public void AddPage(double width, double height, RenderFormat renderFormat, UIElement contentPage)
{
PageContent pageContent = new PageContent();
FixedPage fixedPage = new FixedPage();
fixedPage.Width = width * renderFormat.Value;
fixedPage.Height = height * renderFormat.Value;
fixedPage.Children.Add(contentPage);
((IAddChild)pageContent).AddChild(fixedPage);
fixedDocument.Pages.Add(pageContent);
}
C'est proche d'être bon mais on ne s'est quand même pas tapé du boulot pour rien en créant les formats de feuilles, qu'à cela ne tienne et ajoutons-y cette méthode :
/// <summary>
/// Add a page into the fixed document.
/// </summary>
/// <param name="format">Format of the sheet to use.</param>
/// <param name="orientation">Orientation of the sheet.</param>
/// <param name="contentPage">UI element to add as content of the page.</param>
public void AddPage(SheetFormat format, SheetOrientation orientation, UIElement contentPage)
{
PageContent pageContent = new PageContent();
FixedPage fixedPage = new FixedPage();
fixedPage.Width = orientation == SheetOrientation.Portrait ? format.Width : format.Height;
fixedPage.Height = orientation == SheetOrientation.Portrait ? format.Height : format.Width;
fixedPage.Children.Add(contentPage);
((IAddChild)pageContent).AddChild(fixedPage);
fixedDocument.Pages.Add(pageContent);
}
Puis pour terminer l'ajout on va créer une méthode qui fournira l'orientation Portrait par défaut.
/// <summary>
/// Add a page into the fixed document.
/// The default orientation is portrait.
/// </summary>
/// <param name="format">Format of the sheet.</param>
/// <param name="element">UI element to add as content page.</param>
public void AddPage(SheetFormat format,
UIElement contentPage)
{
AddPage(format, SheetOrientation.Portrait, contentPage);
}
Les seules choses qui nous restent à faire à présent est de sauvegarder le document au format XPS et de charger le dit document dans un document viewer.
Pour la sauvegarde, il faut reprendre la 1ère méthode, sauf qu'au lieu de lui envoyer des Visuals on lui envoie notre fixed document nouvellement créé.
/// <summary>
/// Save the fixed document into an xps file.
/// </summary>
/// <param name="filename">Name of the xps document.</param>
public void SaveToXps(string filename)
{
Package pkg = Package.Open(filename, FileMode.Create);
XpsDocument doc = new XpsDocument(pkg);
XpsDocumentWriter writer = XpsDocument.CreateXpsDocumentWriter(doc);
writer.Write(fixedDocument);
doc.Close();
pkg.Close();
}
Et enfin notre méthode de chargement (qualifiez-là de statique car le chargement se fait en interne). La seule astuce est de créer un XpsDocument avec en paramètre le nom du fichier, et ensuite de passer la séquence du document à la propriété Document du document viewer.
/// <summary>
/// Load the specified xps document and send it into the document viewer.
/// </summary>
/// <param name="filename">Name of the file to load.</param>
/// <param name="documentViewer">Container of the loaded file.</param>
/// <exception cref="System.Exception">Occurs when the filename isn't an xps file.</exception>
static public void ShowGeneratedDocument(string filename, ref DocumentViewer documentViewer)
{
if (Path.GetExtension(filename) != ".xps")
throw new Exception("Error !! The filename need to be a xps file.");
XpsDocument xpsDoc = new XpsDocument(filename, FileAccess.Read);
documentViewer.Document = xpsDoc.GetFixedDocumentSequence();
xpsDoc.Close();
documentViewer.Focus();
}
Conclusion
Et voilà, ce tutorial s'achève. Nous avons vu comment générer un fichier XPS et comment créer nos pages en suivant un modèle de format standard et qui peut être orienté.
Le seul défaut de cette technique est que nous utilisons un FixedDocument ne nous permettant pas de positionner nos objets comme nous le voulons. Néanmoins cette méthode reste très appréciable lorsque nous ignorons combien d'objets nous devons ajouter au document.
