How to show an image using the stored vector (matrix) as a variable in the report generator

Hello,

I'd like to show an image or picture using the image vactor (matrix) in a report. Lets assume that the image is already read by imread(picname) and stored in a variable. Now, having the variable, how can I display the sotred image? The code is similar to the following:

file1.m :

picname='picname.jpg';
myimage=imread(picname);
save('myimagefile','myimage');

Later on, I load the variable from file2.m which generates the report.

file2.m :

import mlreportgen.dom.*;
import mlreportgen.report.*;
load('myimagefile');
rep=Report('Myreport','pdf');
open(rep);

I know if I use Image() function deosn't work, because it reads the associated address to the variable, not the content of the varialbe.

The wrong code is:

imagetoshow=Image(myimage); %I know "myimage" should be an adderss not a variable
add(rep,imagetoshow);
close(rep);

Any help is appreciated.

KSSV,

Thanks for your reply. However, it didn't work with add(rep,imagetoshow). Would you please provide me a code that I could use?

Thanks for your help.

You could use:

imshow(loadedimage)
add(R, Figure())

In general I'd stick with Image even if though requires imwriting your image back to disk (perhaps to tempname from where it can be deleted)

Thanks Sean de Wolski,

The code you provided didn't produce a report, but only a plot. I really hoped that there was other way to embed an image in the reprot from a variable.

Thanks,

Hi Yasser,

I replied without a MATLAB around. You need to snapshot the image from the Figure and set its properties. See example here:
