Personalized Rendering

Request Payload

These controllers take the same product definitions as in the IFrame API, substitute personalized data, and return URLs that link to rendered products. You can render a single product or a product group all at once. You can pass the following common data params in the POST request:

• itemsData sets the content and properties of design elements.
• productTheme binds color themes using IProductThemeConfig.
• productThemeName binds color themes using a theme name.
• productDefinitions defines an array of products based on IProductDefinition or state files.
• userId sets the user ID.

Also, the Preview controller accepts previewOptions specifying the configuration of proof images, whereas the HiRes controller accepts hiResOptions specifying the rendering configuration.

PreviewOptions

The previewOptions object defines the size, resizing mode, and rendering configuration of proof images through the following properties.

You can define these parameters as follows:

inputData = {
    previewOptions: {
        width: 504,
        height: 360,
        resizeMode: "Fill",
        proofImageRendering: {
            fileFormat: "jpg",
            showStubContent: true
        }
    },
    ...
};

HiResOptions

The hiResOptions object allows you to configure the rendering of hi-res outputs and define whether the controller generates URLs that link to proof images through the following properties.

You can define these parameters as follows:

inputData = {
    hiResOptions: {
        RenderProofImages: true,
        renderingConfig:{
            defaultHiResOuputRendering: {
                fileFormat: "pdf",
                dpi: 400
            }
        }
    },
    ...
};

ItemsData

The itemsData object allows you to apply properties to all product pages at once and separately on a per-page basis. Also, the itemsData object personalizes in-string placeholders through the placeholders property. This object complies with the following specification.

itemsData: {
    surfaces: {
        [surfaceName: string]: {
            [itemName: string]: itemData
        }
    },
    [itemName: string]: itemData,
    placeholders: {
        [placeholderName: string]: string;
    }
}

Here, itemsData may contain the following properties.

itemData: {
  image?: string;        // The path to images.
  opacity?: number;      // The opacity of design elements.
  text?: string;         // The content of text elements.
  leading?: number;      // The text leading.
  tracking?: number;     // The text tracking.
  font?: FontSettings;
  textAlignment?: TextAlignment;
  textVerticalAlignment?: TextVerticalAlignment;
  isVertical?: boolean;  // Whether the text is vertical.
  underline?: boolean;   // Whether the text is underlined.
  location?: PointF;
  size?: ItemSize;       // The width and height.
  color?: string;        // The color in a CSS-compatible format.
  borderColor?: string;  // The border color of design elements.
  borderWidth?: number;  // The border width of design elements.
  fillColor?: string;    // The fill color for shapes.
  altColor?: string;     // The alternate color for dashed lines.
  dashWidth?: number;    // The dash width.
  altDashWidth?: number; // The width of alternate dash lines.
  width?: number;        // The width of lines.
  sourcePoint0?: PointF; // The start point of lines.
  sourcePoint1?: PointF; // The end point of lines.
}

TextAlignment and TextVerticalAlignment allow you to align text elements. Using PointF, you can define item coordinates. To define font properties, you can use FontSettings.

FontSettings: {
  postScriptName?: string;
  size: number;
  fauxBold: boolean;
  fauxItalic: boolean;
}

To set up the size of items, use ItemSize. For text elements, this object defines the bounding rectangle.

ItemSize: {
  width: number;
  height: number;
}

All properties of itemsData are optional. Through different variations, you can define any design element supported in Customer's Canvas. The following table details the design elements and their properties that you can pass to the Preview and HiRes controllers.

All the numeric values are measured in points. If you do not pass any property that is appropriate to a design element, say text for bounded text, then the corresponding value from the design template remains unchanged.

The Personalization Sample

The following sample illustrates how you can generate personalized proof images without loading the editor. Replace example.com in baseURL with the domain name of your site.

Examples of Input Data

productDefinitions allows you to specify one or more products through IProductDefinition, which, in turn, allows for setting up the design location, mockups, spines, folding lines, crop marks, and safety lines. Here are several snippets illustrating possible use-cases and input data for this request. You can copy and paste them into the previous personalization example.

A proof image of an 8.5x11 inches flyer

inputData = {
    previewOptions: {
        width: 504,
        height: 360
    },
    productDefinitions: [{
        surfaces: [{
            designFile: "flyer",
            safetyLines: [{
                margin: 10,
                color: "green",
                altColor: "rgba(255,255,255,0)",
                stepPx: 5,
                widthPx: 1
            }],
            cropMarks: [{
                margin: 10,
                color: "red"
            }]
        }]
    }],
    userId: "default"
};

Personalization of in-string placeholders

The following example personalizes the [#Name] and [#Phone] in-string placeholders, the specially formatted strings.

inputData = {
    itemsData: {
        placeholders: {
            "Name": "John Wood",
            "Phone": "555-123-1234"
        }
    },
    productDefinitions: [{
        surfaces: ["businesscard_front", "businesscard_back"]
    }],
    userId: "default"
};

Personalization of color themes and images

For images, you can specify URLs starting from http:// or https:// and links to your public and user images through the public: and user: prefixes, correspondingly. For example, public:company_logos/aurigma.png applies the aurigma.png logo from the \company_logos\ subfolder of the public gallery folder.

In the following example, state files specify the product.

inputData = {
    itemsData: {
        "photo": {
            image: "https://example.com/centralview.jpg",
            opacity: 0.8,
            borderWidth: 1
        },
        "cornerImage": {
            image: "user:tower.jpg",
            size: {
                width: 100,
                height: 100
            }
        }
    },
    productTheme: {
        "mainColor": "rgb(32, 83, 69)",
        "altColor": "rgb(26, 47, 41)",
        "texts": "rgb(176, 143, 37)"
    },
    productDefinitions: [
        "044abd5e-da18-46ff-9053-b019b62baa77",
        "d6c67467-6a3a-466a-9945-288c94b698a3"
    ],
    userId: "default"
};

Proof images of an envelope with preview mockups

In this example, we personalize only the Front page of the two-page product.

inputData = {
    itemsData: {
        surfaces: {
            "Front": {
                "name": { text: "John Wood" },
                "address": { text: "4414 Hill Road, Perth, IL" },
                "zip": { text: "61701" }
            }
        }
    },
    productDefinitions: [{
        surfaces: [{
            name: "Front",
            previewMockups: [{ up: "envelope" }],
            printAreas: [{
                designFile: "envelopeDesign",
                designLocation: { X: 4.1, Y: 4.1 } 
            }]
        },
        {
            name: "Back",
            printAreas: [{
                designFile: "envelopeBack"
            }]
        }]
    }],
    userId: "default"
};
