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.
Yasser

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)

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