display SVG, PNG, GIF, JPEG, TIFF, PPM in new plot frame
Dear R-help
I want to display an image file in a new plot frame.
SVG is my preferred format, but I can also consider
PNG, GIF, JPEG, TIFF, and PPM (from ImageMagick).
By way of background (although not material to this
posting), the image file is generated by a call to
'dot' (part of the 'Graphviz' suite) after the required
.dot file has been produced using hand-crafted R code.

Seems ok on my system. Axis label size changes when cex.axis does.

svg as a spescial case for image
SVG starts to become more useful in browsers like Firefox, OmniWeb,
Opera and soon Safari. There is a couple problem. Since no browser
support svg embedded with img one need to fall back to html from:
<object data="/path/to/img.svg" type="image/svg+xml"
width="512" height="384">Alt text</object>
Second, one need to write the width

insert hyperlink into svg graphic
This was actually the first thing that ChatGPT debugged for me.
The issue was that I was able to click on the link when I displayed the raw SVG in the browser (you can use that to test whether the syntax is even correct), but not when the svg displays inside a html page with the <img ...> tag.
ChatGPT correctly identified the issue and suggested a solution using <object ...> tags

Parsing question, partly comma separated partly underscore separated string
Dear R-list,
I have a partly comma separated partly underscore separated string that I am trying to parse into R.
Furthermore I have a bunch of them, and they are quite long. I have now spent most of my Sunday trying to figure this out and thought I would try the list to see if someone here would be able to get me started.
My data structure looks like this,

????? I'm unable to control the font size in plots to svg.? Consider

R interface to ImageMagick
Hi,
I was wondering if anyone is aware of an R interface to ImageMagick
(www.imagemagick.org)? Since R does not support a lot of image processing
functions, having such an interface could be very useful. Alternatively,
ImageMagick has a couple of different interfaces (including to C and C++). I
was wondering if one can use these to call ImageMagick functions from R.
I am posting a similar

Scripting SVG with R
Since now many browsers support (ECMA/Java-)scripted SVG, I am wondering
whether there are already any examples of inserting R code into SVG
documents (or a Javascript canvas?) either directly, or perhaps more
likely through a JavaScript layer, to dynamically generate graphics or
make them interactive?
I am aware of the excellent packages gridSVG and SVGAnnotation, which
facilitate making

ImageMagick x86_64 update missing binaries (i386 is okay)
The recently released update to ImageMagick (6.0.7.1-14.x86_64) has a
problem on x86_64 -- it's missing /usr/bin/animate, /usr/bin/display, and
/usr/bin/import. The previous ImageMagick-6.0.7.1-12.x86_64.rpm is fine...

ImageMagick : Centos GUI ?
I accidentally discovered 'convert'. It is a command line utility.
Changing a file from png to gif works like this
convert aaa.png aaa.gif
Amazingly simple, powerful and effective.
I've since discovered it has an amazing list of options
convert --help

and a web site

ImageMagick/Rmagick replacement?
Hi, everyone!
I have been recently hit by ImageMagick/Rmagick memory leak issues.
I know I can lesson the problem by manually starting up GC each time
I use Rmagick library but ImageMagick seems to use way too much
memory nevertheless. (on shared hosting setup anyway)
Is there a decent replacement for ImageMagick library? I used to
think ImageMagick was quite efficient because its

file_column: patched for imagemagick and validation
Hi all,
I patched file_column to add imagemagick transformations of uploaded
content. I added an options hash, and it takes the :magick and
:format keys. :magick is a string of imagemagick command line options
for convert (Reference:
http://www.imagemagick.org/script/convert.php). Format is an optional
extension for the finished image. If Imagemagick recognizes the
extension, then it will

svg malformed on CentOS (epel R)
There is an issue with the default svg device on a centos workstation that I
am using. It does not result in an error, but it produces malformed svg
images. Exactly the same script works just fine on an ubuntu box. On Ubuntu
I am using R binary that comes with maverick, on centos I am using the
latest R binary from EPEL. Other than that both boxes are pretty clean, with

Image conversion with ImageMagick doesn't work on CentOS, but it works fine on Debian Lenny.
I recently came across the need to convert jpg images with IM, did a
standard install of "yum -y install ImageMagick" and found that
images converted with CentOS's base port of IM would actually corrupt the
images, yet using the same (albiet different version, different distro)
software
didn't corrupt the images at all.
By corrupted, I mean, the bottom portion of the image under
