[Chimera-users] Saving Images

[Elaine Meng]

Hi Eric,
One further idea is that you can use sticks instead of lines, although the sticks can't be dotted or dashed.  

Distance monitors, H-bonds, metal complexation lines etc. are all pseudobonds. One way to change a pseudobond into a stick is to Ctrl-click to select it, then use the Selection Inspector (open by clicking the green magnifying glass icon near bottom right of Chimera window) to change "bond style" from "wire" to "stick".  You can make the stick thinner by reducing the "radius" in that same dialog.  All this can also be done with the "setattr" command, as explained in a recent post:

So if you are running an older Chimera or a daily build of any vintage you might try the latest production release 1.6.2.

>> When you save an image with supersampling, initially the image is drawn larger and then sampled down to the final requested size.  The problem is that graphics drivers have an upper bound on linewidth that can be drawn, so the line can only be so fat in the initial image, and then when it is sampled down, it is thinner.  The image dialog will report (near the bottom) the maximum attainable linewidth in the final image given the requested image dimensions and the supersampling level.

The problem arises when we save the image the 'thickness' of the distance line doesn't change on the actual saved image. So no matter what the thickness is on chimera the image will always show the distance line as being less thick.
