I have done a figure using TikZ that uses the shadows.blur package. Using qtikz (my TikZ editor), I have exported the image as an eps file.

In my document, I use \includegraphics{theimage} and pdflatex automatically convert my eps to a pdf (theimage-eps-converted-to.pdf). However, when there is a shadow, the image is not vectorial! (if I manually do epstopdf, I have the same issue in the pdf)

If I export in pdf directly from qtikz, the image is exactly as expected. So my question is: is there a way to fix the way pdflatex converts my eps files?

  • How is the eps converted? pdftex doesn't do that. Commented Aug 6, 2014 at 12:38
  • @MartinSchröder pdflatex does that automatically.

  • Normally it doesn't. And I was the maintainer once. Are you using MikTeX? Commented Aug 9, 2014 at 21:20
  • I don't know what is MikTex. I only use pdflatex on my Debian.

  • Then I'm very curious what you do to get the eps converted. Please edit your question to include a complete minimal example. Commented Aug 10, 2014 at 18:30

I suspect the shadowing uses PDF features, which are not available in PostScript. From the documentations, pgf-blur:

This effect can be achieved in TikZ/PGF with the circular drop shadow key,

And from the PGF manual:

In addition to the general shadow option, there exist special options like circular shadow. These can only (sensibly) be used with a special kind of path (for circular shadow, a circle) and, thus, they are not as general. The advantage is, however, that they are more visually pleasing since these shadows blend smoothly with the background. Note that these special shadows use fadings, which few printers will support.

Export the image as PDF and pdfTeX can include it directly without the need to run a converter for the down-graded PostScript file (the conversion is actually done by ghostscript).

  • "Note that these special shadows use fadings, which few printers will support." => Is that something I should worry about? Or if I use pdf it does not matter?

  • I think, it is quite ok for the PDF format, it is the job of the PDF printing program to make it appropriate for the printer (converting to bitmaps, ...). Commented Aug 5, 2014 at 18:12
  • an "ff" ligature was missing from the first quote, in "e...ect". fixed. Commented Aug 5, 2014 at 18:52

I solved this problem (so happy, and I share):

Step 1: Remove the entire MikTeX exists on your computer using the Control Panel, after removing deleted folder named MikTeX in C:\ Program files (x86 ) to avoid errors when resetting because the same name folder (uninstall is complete without restarting the computer)

Step 2: Reinstall the MikTeX below (no need to install the program editor as texstudio, Texmaker, viettex, ...), this error is due to foundation MikTeX

MikTeX file download link: click here

After downloading, you unzip. Installation file named setup-2.8.3553.exe in directory MikTeX /setup

Step 3: Install the file setup-2.8.3553.exe as usual, remember to tick select Complete MikTeX to install the full version.

Note when using:

Note 1: The order declaring the package ordered to order from top to bottom as follows:

\ usepackage {graphicx}

\ usepackage {epstopdf}

\ usepackage {subfigure}

Note 2: Before running TeX files, please ensure that you have deleted the corrupted PDF files are output from run error before (just leave a tail .eps image file)

Please vote me if it works !!!!
