Re: [PyMOL] Stereo labeled figs?, even with powerpoint!

[Anthony D. <A....@us...>]

If you don't have a program such as Illustrator or Canvas, you can do the 
same thing in powerpoint.

However, there is a small problem with exporting pictures from powerpoint, 
but it can be overcome.  I've pasted a description below.

____________________________________________________________________________________

PowerPoint is actually a quite effective tool in creating precise graphics, 
such as stereo pictures with labels, or other drawn objects, such as 
arrows.  Unfortunately, exporting pictures from PowerPoint at reasonable 
resolution is non-obvious.

The problem:  When you copy an object from PowerPoint and paste it into a 
non-Microsoft Office program (eg Paint, Photoshop), the image is pasted 
with a resolution determined by the slide size.

The solution:
    * In PowerPoint, go to File, Page Setup.
    * Increase the slide size width and height.  A five-fold increase 
should be sufficient. eg. increase width from 24cm to 120cm, height from 
18cm to 90cm.  Be sure that you don't change the aspect ratio (width/height).
    * Select your objects (grouped or ungrouped).
    * Copy.
    * Go to Photoshop.
    * Create a new image (size is irrelevant).
    * Paste the image.
    * Save the image in your favourite format.
