[GRASS-dev] composer preview

GRASS GIS GRASS GIS developer
1

So that was easier to test than I thought. I had not reinstalled X11 on one of my computers since updating to OS X 10.8. Even with PIL installed, here is what happens:

  1. When I click the preview button, I get the following screen.

If I click “continue” it takes me to the XQuartz project site to install XQuartz. If I click cancel, I get the following error:

So this is a PIL/Ghostscript/X11 issue. Note that Ghostscript IS installed on my Mac by default.

After installing a XQuartz, the composer preview works. This is not a huge problem on the Mac then, but it seems like people should not need to install X11 solely for converting pdf2png. No other way?

Anna,

I am happy to test. But composer preview has worked for me in the past once I installed PIL. I do have Ghostscript. I installed it manually long ago, but I’m pretty sure that it comes with the Mac OS these days.

I thougt the preview was not working for you because of the ticket
[1]. If it is working there is probably nothing to test.

Thanks anyway,
Anna

Hi Michael,

could you do a test for me with the cartographic composer? The preview
can be broken for several reasons [1]. Could you check that you have
Ghostscript installed? Then, if you have it, try if it is on the PATH.
If not, could you put it on the PATH? Then it could work on Mac. But
there is probably no chance to make it work on Windows.

Thanks,

Anna

I don't know how Ghostscript handles PostScript and why is X11 needed.
And I can't see any way to change it.
