Inkscape: Problem importing PDF

Filed under: Windows — Tags: , , , , , , , , — Christopher Kramer @ 18:39

I just had problems importing a PDF into Inkscape. The PDF was an image of a graph generated by igraph for R. When importing, the circles of the vertices got replaced by the letter “q”.

I found the following workaround: I printed the PDF into a new PDF using FreePDF. The resulting PDF could then be imported into Inkscape without problems.

My original problem was that I wanted to include the graphs from igraph for R in Powerpoint as a vector graphic. As Powerpoint cannot include PDFs as graphics, I wanted to save the graphs as emf-Files. But the emf-Files exported by igraph for R look completely messed up when imported in Powerpoint. The PDFs exported by igraph for R are fine, so I wanted to import them into Inkscape and save them as emf. A bit of a long way, but it works and it does not result in an ugly pixel graphic.

Maybe somebody has similar problems and finds this useful.

Windows 7: On a multi-screen setup, place windows at one half of a screen

Filed under: Windows — Tags: , , , , , , , — Christopher Kramer @ 11:08

With Windows 7, you can easily move windows on one half of the screen by dragging them to the left or right edge of the screen. This is called “Snap” and is very handy. Watch Microsoft’s video on Snap if you don’t know it yet.

But on a multi-screen setup with two screens side-by-side, you can only place a window at the right half of the right screen or the left half of the left screen with Snap. You cannot place a window at the left half of the left screen because there is no “magic edge” there. Of course you can move and resize it manually. But there is a faster way:

[Windows-Key] + [Left arrow]

This places the window at these positions:

  1. Left half of left screen
  2. Right half of left screen
  3. Left Screen
  4. Left half of left screen
  5. Right half of right screen
  6. Right screen

Just press [Windows]+[Left] again to move it to the next position listed above. You can press [Windows] + [Right arrow] to move it the other way round (starting to the right half of right screen).

I don’t know if any other Windows version supports this as well, I guess at least Windows 8 supports it as well (in desktop mode).

Happy window-moving! 🙂
