save a plot

Hi Hi,

i have a problem with saving a plot in a directory as a figure(.tif). I have a main function. Each time i run my code, the code reaches a directory, takes image sequence and make some outputs. What i need to do, is to save some output plots in a directory. I know how to save a figure, but it does not work for plots! (specially i have a figure with hold on and i make plot inside the figure and want to save it!)

Thanks,

Azi

It isn't clear to me what you are asking. Can you include code for a very simple example?

i meant : print('-dtiff','plot.tif')

Does this work for you?

plot(1:10)
print('-dtiff','plot.tif')

[azarm]

tnx, it works :)

I used:

print('-dtiff','example.tif')

now, i need to save the image (example.tif) in a specified directory.

My code is:

baseFileName = sprintf('TEST%d.tif', j);

fullFileName = fullfile(pathName, baseFileName);

imwrite(example, fullFileName);

but this error occurs: ??? Undefined function or variable 'example'

any idea?

tnx, Azi

Two points:

(1) The most basic error you are making is that with your syntax, MATLAB is looking for a variable named "example", which does not exist. I guess you meant to use 'example.tif' (enclosed in single quotes so it interprets that as a string, not a variable).

(2) I am now not 100% sure what you are trying to do, but if you are just trying to save a MATLAB plot, you do not need to use imwrite. You just need to use print(), but with the full file name specified. Will this do what you want?:

print("-dtiff",fullFileName)

[azarm]

(1) well. i tried 'example.tif' as input to imwrite but the

first argument should not be a string!

(2) I want to do exactly this job. But there are some points. I take some images from a folder, run the code, take some figures and plots. So i want to save them in a new folder with proper name.

example1.tif

example2.tif

.

.

the index should be created outomatically. that's the reason i used : sprintf('TEST%d.tif', j); (j would be incremented in the code)

any idea how can i do it?

tnx

If you can create a variable with the full path to the directory, which you seem to be able to do, then you should be able to use

print('-dtiff',fullFileName)

as I said before. (I accidentally used double quotes instead of single quotes before.)

[azarm]

you're right! It works.

Tnx for your help
