Thank you, Manoj

I tried to change picture format wit 'bmp'.

So I changed 'png' to 'bmp' in both oml file and py file.

But it makes error.

I want better resolution rather then png.

Can you help me about this? ; use 'bmp' picture format.

we don’t support creating of PDF and PPTX from COMPOSE OML in 2017.3, these features are coming up in next releases. We can leverage COMPOSE – Python (2way bridge) to accomplish this task.

below are the steps with example:

*    Install “fpdf” external library package of python. (see attached install_fpdf.png)  
  *    Save the figures in OML (attached OML file)   
 
                           for i =1:10

f=figure(i);

plot(rand(1,100));

saveas(f, ['demo',num2str(i),'.png']);

end

outfile = 'mypdf.pdf';

*    Export the pdf output file name to Python and evaluate the pythonfile (attached 'python_pdf.py')  
 
                    exporttopython('outfile','outfile');

evalpythonfile('python_pdf.py'); % comments are added in the file for better understanding.

Hope this helps.
