Hi all,

I have some problem with the quality of copied figure. If I plot something and then I chose edit-copy figure, no problems, I can paste them in word and the quality is good. BUT if I do some modifications on the figure, for example I add some text or shapes, then if I do copy figure, the quality of the pasted image in word is lower.. For example it's impossible to read well the axis label.. You have any idea of the solution for this problem?

Thank you

Go to copy options and choose "Metafile" for clipboard format. The resolution is pefect, alghouth it said "may loose information" but i did not have that problem yet.

what's the point of commenting a 3 years old comment on a 10 years old thread?? moreover with a comment without any useful content.

Thanks..........choosing "Metafile" for clipboard format worked for me!

Someone else just asked about saving and I referred him to the FAQ: http://matlab.wikia.com/wiki/FAQ#How_do_I_save_my_figure.2C_axes.2C_or_image.3F_I.27m_having_trouble_with_the_built_in_MATLAB_functions. (Make sure the final dot is included in the URL). The FAQ also which mentions export_fig(), which is the consistently the most downloaded File Exchange submission. I guess that's why questions on saving figures are the MOST commonly asked question - we get 1 to 3 a day or so.

try saving the figure from matlab as a .jpg file by typing

        ff =(C:\My Documents);
        fnout = [ff, '\FigureName', num2str(1,'%.2d'), '.jpg'];
        print('-djpeg','-r150',fnout);

This will then save the figure in my documents. Then in word go to inser--> picture.

If you want really high quality figures, you should save your figures as .eps files, but I dont think that word accepts these.

Thank you for the answers.

@lestyn: I can manually export in jpg, but the situation is the same, even worse maybe..

@Malcom: yes, I've already tried export_fig, but nothing changes.

The key point is that I don't understand why the copied figure changes between the situation "figure without any change", and the "figure after that I add some shapes"... It should be the same!

An example script would help a lot.

This will not improve the image like export_fig but it does reproduce what's on screen -so if if you do not see grotty graphics on screen this may help.

It calls

this=MUtil.getFigureHWLWContainer(fh);

which is defined in Project Waterloo http://sourceforge.net/projects/waterloo/, and returns a reference to the MATLAB heavyweight/lightweight container but you could get that in other ways e.g. with Yair Altman's findjobj.

Dependent jars are part of the standard MATLAB distribution and are on the static javaclasspath.

MATLAB seem to build graphics in an offscreen buffer then paste a bitmap into the Java AWT Canvas. Here, that is replaced with an Apache Batik SVGCanvas. The MALAB graphics will be embedded as a bitmap in the file.

function SaveAsSVG(fh, str)
% SaveAsSVG saves a MATLAB figure to an SVG file
% Example:
%     SaveAsSVG(figurehandle, filename)
% where filename is the fully qualified name of the file to write.
