Creation

Description

example

imageObj = mlreportgen.dom.Image(imagePath) creates an mlreportgen.dom.Image object with the Path property set to the path of an image.

Note

The contents of the specified image file are copied into the output document when the document is closed. Do not delete or overwrite the image file before closing the document. If you create an image file and the corresponding mlreportgen.dom.Image object in a loop, for each loop iteration, use a unique file name for the image file.

Properties

expand all

Path of the image file, specified as a character vector. This property is read-only.

Image height, specified as a character vector or string scalar that consists of a number followed by an abbreviation for a unit of measurement. For example, "2in" specifies two inches. Valid abbreviations are:

  • px — pixels (default)

  • cm — centimeters

  • in — inches

  • mm — millimeters

  • pc — picas

  • pt — points

  • % — percent

When the Image object is created, the Height property is set to a value based on the image file specified by the Path property.

Image width, specified as a character vector or string scalar that consists of a number followed by an abbreviation for a unit of measurement. For example, "2in" specifies two inches. Valid abbreviations are:

  • px — pixels (default)

  • cm — centimeters

  • in — inches

  • mm — millimeters

  • pc — picas

  • pt — points

  • % — percent

When the Image object is created, the Width property is set to a value based on the image file specified by the Path property.

Map of hyperlink areas in this image, specified as an mlreportgen.dom.ImageMap object. The Map property applies to only HTML and PDF reports.

See Create Image Maps.

Name of image style, specified as a character vector or string scalar. The StyleName value must be a style in the style sheet of the document or document part to which this image is appended. Format objects in the Style property of this Image object override the style in the style sheet.

Note

The StyleName property is ignored for Word output.

Formats that define the style of this image, specified as a cell array of DOM format objects. The formats override the corresponding formats defined by the style specified by the StyleName property. See Create and Format Images.

Custom attributes of this document element, specified as an array of mlreportgen.dom.CustomAttribute objects. The custom attributes must be supported by the output format.

Parent of this image, specified as a document element object. This property is read-only.

This property is ignored.

Tag for this document element, specified as a character vector or string scalar.

The DOM generates a session-unique tag as part of the creation of this object. The generated tag has the form CLASS:ID, where CLASS is the object class and ID is the value of the Id property of the object. Specifying your own tag value can help you to identify where an issue occurred during document generation.

ID for this document element, specified as a character vector or string scalar. The DOM generates a session-unique ID when it creates the document element. You can specify your own ID.

Open Live Script

Use an mlreportgen.dom.Image object to specify an image that you want to include in a report. Include the image in the report by appending the Image object to the report.

Import the DOM package so that you do not have to use long, fully qualified class names.

import mlreportgen.dom.*

Create a report and add a title for the image using an mlreportgen.dom.Paragraph object.

d = Document("myImageReport","docx");

p = Paragraph("Plot 1");
p.Bold = true;
append(d,p);

Save a plot as an image file.

x = 0:pi/100:2*pi;
y = sin(x);
plot(x,y);

saveas(gcf,"myPlot_img.png");

Create an mlreportgen.dom.Image object that specifies the path of the image file. Specify that the width and height are 4 inches. Append the Image object to the report.

plot1 = Image("myPlot_img.png");
plot1.Width = "4in";
plot1.Height = "4in";
append(d,plot1);

Close and view the report.

close(d);
rptview(d);
