Class MergeFieldImageDimensionUnit

java.lang.Object
    extended by com.aspose.words.MergeFieldImageDimensionUnit

public class MergeFieldImageDimensionUnit 
extends java.lang.Object

Utility class containing constants. Specifies an unit of an image dimension (i.e. the width or the height) used across a mail merge process.

Example:

Shows how to set the dimensions of images as MERGEFIELDS accepts them during a mail merge.
Document doc = new Document();

    // Insert a MERGEFIELD that will accept images from a source during a mail merge. Use the field code to reference
    // a column in the data source containing local system filenames of images we wish to use in the mail merge.
    DocumentBuilder builder = new DocumentBuilder(doc);
    FieldMergeField field = (FieldMergeField) builder.insertField("MERGEFIELD Image:ImageColumn");

    // The data source should have such a column named "ImageColumn".
    Assert.assertEquals("Image:ImageColumn", field.getFieldName());

    // Create a suitable data source.
    DataTable dataTable = new DataTable("Images");
    dataTable.getColumns().add(new DataColumn("ImageColumn"));
    dataTable.getRows().add(getImageDir() + "Logo.jpg");
    dataTable.getRows().add(getImageDir() + "Transparent background logo.png");
    dataTable.getRows().add(getImageDir() + "Enhanced Windows MetaFile.emf");

    // Configure a callback to modify the sizes of images at merge time, then execute the mail merge.
    doc.getMailMerge().setFieldMergingCallback(new MergedImageResizer(200.0, 200.0, MergeFieldImageDimensionUnit.POINT));
    doc.getMailMerge().execute(dataTable);

    doc.updateFields();
    doc.save(getArtifactsDir() + "Field.MERGEFIELD.ImageDimension.docx");
