Hello,
I would like to read an image and to plot anything inside. Then save this figure with a good resolution. I used this code :
figure,
imshow(image);
hold on;
plot(...);
hold off;
F = getframe;
imwrite(F.cdata,directory);
But the image out dont' have the same resolution that image in. Could you help me please ?

Axel,
By using the format TIFF, you can control the resolution horizontally and vertically , that is also available for other extensions, like JPEG you have the parameter Quality , or PNG that contains two scalars XResolution & YResolution , here is an example :
I=imshow(imread('circuit.tif'));
hold on,
plot(100*randn(100,1))
hold off
F=getframe;
imwrite(F.cdata,'C:\test.tiff','resolution',[100 100])
