MATLAB: Adding an image directly from MATLAB into Report Generator

image processingImage Processing ToolboxMATLAB Report Generatorreport generator

I am aware of adding a saved image from the drive into a report using mlreportgen.dom.Image class. I am trying to write a color uint8 matrix into a Word report, is this possible? Or must I save the matrix to a tiff, create a mlreportgen.dom.Image object and then write that to the report?

I am trying to avoid having to write temp files to the disk if the matrix is already in memory. Can I create an Image object without a hard drive directory?

Thanks for any insight.

You must save your color matrix on disk in one of the image file formats supported by Word. The Report Generator's Image object alllows you to use a MATLAB script to store that image file in a Word document (docx) package.

MATLAB: How to scale titlepage image

Hi John,

Considering you are using Report API, you can specify the TitlePage object's Image property as a DOM Image object instead of the image path. The DOM Image class has properties to specify custom height and width. With DOM Image, you can also use ScaleToFit format to automatically scale a large image to fit the page boundaries.

Below is an example that adds a custom size image to the title page:

% Create a report
rpt = mlreportgen.report.Report('output','pdf');
% Create title page
tp = mlreportgen.report.TitlePage();
tp.Title = 'Title Page Example';
tp.Subtitle = 'Report API';
tp.Publisher = 'MathWorks';
tp.PubDate = date();
% Add a custom size image to the title page
domImage = mlreportgen.dom.Image(which('b747.jpg'));
domImage.Height = '3in';
domImage.Width = '3in';
tp.Image = domImage;
% Add the title page reporter to the report
add(rpt,tp);
% Close and view the output document
rptview(rpt);

Thanks,
