Hi I must convert a graph (a .dot) to a map and to a png because I must generate dependencies graph with doxygen using graphviz. But I have a error:
error: problems opening map file
If I do dot -v I have
dot - graphviz version 2.38.0 (20140413.2041)
libdir = "/usr/local/lib/graphviz"
Activated plugin library: libgvplugin_dot_layout.so.6

The plugin configuration file:

pic plain plain-ext pov ps ps2 svg svgz tk vml vmlz xdot xdot1.2
loadimage : (lib) eps gif jpe jpeg jpg png ps svg
There isn't map and png for render
Moreover if I do dot -Tpng
Format: "png" not recognized. Use one of: canon cmap cmapx cmapx_np
dot eps fig gv imap imap_np ismap pic plain plain-ext pov ps ps2 svg
tk vml vmlz xdot xdot1.2 xdot1.4
It seem that I have not the library for png and map.
How can I fix the problem?
(I do not remember how at the time I installed grapghviz)
(I'm working on Linux SO)
Graphviz plugins need to be registered before they can be used. In Windows, open the command prompt as admin and type dot -c to register. You can verify it by typing dot -v
I had the same problem on Centos 7 and I was able to solve it by
installing the graphviz-gd package with the command yum install graphviz-gd
After the installation I executed dot -c and now dot -v shows the following devices:
canon cmap cmapx cmapx_np dot eps fig gd gd2
gif gv imap imap_np ismap jpe jpeg jpg pic plain
plain-ext png pov ps ps2 svg svgz tk vml vmlz
vrml wbmp xdot xdot1.2 xdot1.4
Moreover I use the cmapx to create the map file.

I had same issue on macos 10.14. Solved the issue by reinstalling graphviz, and somehow it says 'not linked' as following
Warning: graphviz 2.47.3 is already installed, it's just not linked. To link this version, run: brew link graphviz
So end up with the following two commands:
brew install -f -s graphviz
brew link --overwrite graphviz

I am trying to create a Graphviz chart with an SVG image embedded in a node, but the SVG image does not display whereas using a PNG image works fine. For example, I download this test image, and then use the following code
digraph G {
a [label=<<TABLE><TR><TD><IMG SRC="/full/path/Test.svg"/></TD></TR></TABLE>>];
a -> b;
}
Executing
dot graph.gv -Tpdf -o graph.pdf
Produces a PDF with a empty spot where Test.svg should be. Graphviz does not report any error message. I am doing this on macOS with Graphviz 2.40.1 installed via Homebrew. I have had no better luck on Windows 7, although on Windows Graphviz reports an error, Warning: No loadimage plugin for "svg:cairo,
I spent hours banging away on this problem on OS X High Sierra. Finally got it working. I had to install graphviz using option --with-librsvg:
$ brew install graphviz --with-librsvg --with-app --with-pango
i'm trying to convert a png file to gif with:
convert 1.png 1.gif
convert: no decode delegate for this image format `1.png' # error/constitute.c/ReadImage/533.
convert: missing an image filename `1.gif' # error/convert.c/ConvertImageCommand/2919.
and it's not working on my imagemagick installation on OSX as you can se above, I installed it with brew and when running convert it shows the following delegates:
$ convert -list configure| grep DELEGATES
DELEGATES bzlib freetype jpeg jng jp2 png tiff x11 xml zlib
On another computer the command works and this are the delegates:
$ convert -list configure| grep DELEGATES
DELEGATES bzlib mpeg freetype jng jpeg lzma png tiff webp xml zlib
The missing delegates on the computer that doesnt works are: mpeg, lzma and webp. However I wonder which of those could be required for open a gif file.
The problem is the decode (i.e. read) delegate, so it is failing to read the input file rather than to write the output file.
Try:
brew rm imagemagick
brew install libpng
brew install imagemagick
After upgrading gnuplot from 4.6 to 5.0.1, I encounter the following error:
set terminal pdfcairo size 3.0in,2.25in font ',8'
^
"plot.plt", line 114: unknown or ambiguous terminal type; type just 'set terminal' for a list
How can I fix it?
PS: pdfcairo works fine in the previous version (4.6).
I install the gnuplot by the following command:
#build it:
./configure --with-cairo
make
#install it:
sudo make install
As described in GNUPLOT Version 5.0.1 Release Notes, the pdfcairo is included by default.
Cairo/pango/wxWidgets This set of terminals includes
pngcairo, pdfcairo, epscairo, and cairolatex for output to a file
wxt for interactive display All of these will be built by default if the
configuration script finds the required libcairo, libpango, libcairo,
libwxgtk, and related support libraries To disable these terminals:
./configure --without-cairo ./configure --with-cairo --disable-wxt
I fix it with the kind reminder of #Christoph.
To tackle this issue, install the dependency libraries for cairo-based terminals by the follwoing command:
sudo apt-get install libcairo2-dev
sudo apt-get install libpango1.0-dev
And then compile gnuplot again:
#build it:
cd gnuplot-5.0.1 ; ./configure ; make
#install it:
sudo make install
Now, everything is fine. Enjoy it:-)

I followed the instructions on http://guides.spreecommerce.com/developer/getting_started_tutorial.html
Additionally, I followed instructions on http://codeofalice.com/code/installing-rmagick-on-windows-7/ to install imagemagick and rmagick gems. No errors reported.
When I run identify I get

The demo site runs, but the images are missing. Additionally, I can't upload images (no errors) - they just don't upload. I believe it is something related to ImageMagick, but am not sure.
Run bundle exec rake spree_sample:load It worked for me!
I've installed the Mac OS X binaries from the graphviz website and downloaded this test .dot file.

It produces an image, but none of the embedded images are visible.

This seems to imply that I can load images? Am I doing something wrong?
Thanks!
Try removing style=invis for each icon node. I don't know what was the author's idea in making it invisible. Worked for me on Win7.
