[Chimera-users] FW: eps image in publication quality

Hi Mahendra,
	Yeah, Greg’s response was appropriate for the main “Save Image” dialog, not the “Save EPS” from the sequence window.  The latter is, as I said earlier, “infinite” resolution.  Nonetheless, Microsoft products may not do a good job of rendering PostScript files, particularly on Windows machines (PostScript is better supported on Mac).  Therefore you might want to use something like Photoshop if you have that available.  Nonetheless, if you *print* from PowerPoint I think you will see that you get a good looking result.  Also, zooming in in PowerPoint will give you a somewhat better looking image to look at / work with, but not as good as what gets printed.
	When I open your file on my Mac using Preview, it looks fine.  I’ve attached a screenshot.  I’ve also attached the PDF equivalent of your EPS files, in case PowerPoint can handle that better for whatever reason.
	One thing you might also possibly want to do is to change both your model’s colors to white, so you don’t get that garish magenta background on the second sequence name.  Just go to the model panel, click on the small color well on that model’s line which will bring up a color editor and change the model color to white.

An easy way to get a reasonable resolution is to switch to print units in the Save Image dialog, and choose a size in inches or cm.  The default "Print resolution" of 100dpi is generally more than adequate since printers need many dots to represent a single pixel and most computer monitors are roughly 100dpi.

The image in the pop of window is nice but the saved image in the eps format is not so clear. Let me suggest how to save the image in the publication quality.
