Hey guys,

I'm using Generate Report to creat a pdf-File. By using a surface plot it is possible to add the image to the pdf-file. I also want to add another rgb-image to this pdf-file, but I get the following error message:

Error using mlreportgen.report.Figure/createSnapshotFigure

Figure is invalid. Please use valid path of the figure file or valid figure handle

....

Error in test (line 58)

add(report,c1);

I use the following code:

%Import the DOM and Report API packages so you do not have to use long class names.
import mlreportgen.dom.*
import mlreportgen.report.*
%Create a container to hold the report content.
doctype = 'pdf'; %Also working with 'docx'
report = Report("Auswertung", doctype);
open(report);
%% Create title page
tp = TitlePage("Title", "Ergebnisse test", "Subtitle", "test");
add(report, tp);
%% Table of Contents
toc = TableOfContents;
add(report, toc);
%% Create a chapter with the title
c1 = Chapter("Title", "Ergebnisse");
c2 = Chapter("Title", "Nächstes Kapitel: ");
%% Data
s1 = Section("Messdaten");
p1 = Text("Aufnahme in [cd/m²]");
s2 = Section("Maske");
[name_gray, path_gray] = uigetfile('*.*', 'Select gray value image');
[name_rgb, path_rgb] = uigetfile('*.*', 'Select rgbe image');
picture_data = dlmread(fullfile(path_gray, name_gray));    %Example Path
groups_rgb = imread(fullfile(path_rgb, name_rgb));              %Example Path
%% Gray value image
figure();
ax = gca;
Fig1 = Figure(surf(ax, picture_data));
%Plot the measurement data as surf plot
axis equal
shading interp
colorbar
view(0,-90)
 
add(s1, p1);
add(s1,Fig1);
close(gcf);
%% RGB image
figure();
imshow(groups_rgb);
Fig2 = Figure();
add(s2,Fig2);
%% Create Report
add(c1, s1);
add(c1, s2);
add(report,c1);
add(report,c2);
close(report);
rptview(report);

I use a MacBook Pro (Mac OSX), Matlab Version R2019a. I tryed it in some different versions but its just not working. Maybe someone of you can help me. Thank you very much!

Best, Raphael

在 MATLAB Online 中打开

That error is thrown by the mlreportgen as you have closed the Fig1(line 48: close(gcf);), you can remove the error by not closing the figure window or you can save Fig1 as a Document part as shown below:

%% Gray value image 
figure(); 
ax = gca; 
Fig1 = Figure(surf(ax, picture_data)); 
%Plot the measurement data as surf plot 
axis equal 
shading interp 
colorbar 
view(0,-90) 
Fig1 = getImpl(Fig1,report); 
add(s1, p1); 
add(s1,Fig1);
