I am receiving an error in a compiled script for report generator.
Here is the script:
makeDOMCompilable();
import mlreportgen.report.*
import mlreportgen.dom.*
rpt = Report('Test','pdf');
%open(rpt);
% titlepage
%I = imread(img);
%imshow(I);
tp = TitlePage;
%location = pwd;
tp.Title = 'Just a Test';
tp.Image = which(strcat('duel.jpg'));
%tp.Author = Analyst();
tp.Publisher = 'Mike Fisher';
tp.PubDate = date();
tp.Subtitle = 'GTG';
add(rpt,tp);
add(rpt,LineBreak);
close(rpt);
rptview(rpt);
Runs fine in the command window. Compile it and run, get this error:
Error using mlreportgen.dom.Image
Invalid image type: .
Error in mlreportgen.report.TitlePage/getImageReporter
Error in mlreportgen.report.TitlePage/getImag
Error in mlreportgen.report.ReportForm/fillHole
Error in mlreportgen.report.TitlePage/processHole

It seems that duel.jpg is not included in the compiled script, so tp.Image is not an image format then add(rpt,tp) gives an error.
You need to add duel.jpg in "Files required for your application to run" of Application Compiler or add "-a duel.jpg" option in mcc command.

That does not solve the problem. The report generator must be able to look at several different file folders and pick a particular image (all named the same) from a specific folder. I cannot compile the images with the application, they change.

Further efforts produce not working when running the stand alone app, but launching Command Prompt and running from within Command Prompt does work.
