MATLAB: My .eps file get bad resolution when I transfer it to power point

epspowerpoint

Hi,

I have saved some .eps files using MATLAB's saveas function. However, when I try to insert them in powerpoint the resolution becomes bad. Why does this happen? Are there a solution to this? I cannot save all the files again, this would take too much time.

When the renderer of the Matlab figure is 'Painters', the created EPS files are vector graphics. But PowerPoint and Word tend to display the embedded TIFF preview only. Word inserts the high-quality EPS when you print the text on paper or in a PDF, but PowerPoint slides are not necessarily printed.

When the 'OpenGL' or 'ZBuffer' renderer is used, the EPS-export contains a rastered image and the resolution can depend on different parameters. Then exporting a PNG is usually more convenient and allows to control the output more accurately.

It is likely that the font used when exporting the "times" symbol from MATLAB to EPS is not the same as the font that Illustrator uses to interpret the TEX symbols.

Possible workarounds include:

A. Use latex instead of tex:

% create legend 
l = legend('this'); 
% change legend string & interpreter 
set(l, 'string','this $$\times$$ that', 'interpreter', 'latex')

B. Another possibility is to use "zbuffer" or "opengl" to create the EPS file with a raster (bitmap) image of the plot. This should look correct but content modification will be limited in Adobe Illustrator:

print -deps -zbuffer repimage.eps
