Generate PDF image with 76cm x 240cm

Hello!

I have specific problem. I have matrix 76x240 with binary value...

I need to generate large size image in pdf, jpg or png format (76cm x 240cm) from figure?

Any idea?

This is my simple code:

clear all

close all

a = 76;

b = 240;

x = randi([0 1],a,b);

imshow(x,'Border','tight','InitialMagnification',500);

hold on;

[rows, columns] = size(x);

for row = 1 : 1 : rows+1

line([1-0.5, columns-0.5], [row-0.5, row-0.5], 'Color', 'r');

end

for col = 1 : 1 : columns+1

line([col-0.5, col-0.5], [1-0.5, rows-0.5], 'Color', 'r');

end

for i=1:b

for g=1:a

if x(g,i)==0

plot(i,g,'g+','MarkerSize',12);

end

end

end

set(gcf, 'Position', get(0, 'ScreenSize'))

All you have to do is put this at the end of your code:

set(gcf, 'units', 'centimeters', 'PaperPosition', [0 0 240 76])
saveas(gcf, 'name_of_your_pic.png')

That should do the trick.

Thanks a lot!

and for PDF

set(gcf, 'units', 'centimeters', 'PaperPosition', [0 0 240 76]);
set(gcf, 'PaperUnits', 'centimeters', 'PaperSize',[240 76]);
print -dpdf -opengl name_of_your_pic
