Error: attribute not recognized u and n

[chanbuu]

I want to convert some .svg files to .png files using ImageMagick.
But -resize Option doesn't work well in my server.

The command that I entered is here.

Code: Select all

convert a.svg -resize 1024x1024 b.png

This command has worked well in my local server. However, Don't work well in service server.

The Error is

Code: Select all

attribute not recognized: n
attribute not recognized: u
attribute not recognized: n
attribute not recognized: u

This Error is output from "ImageMagick/magick/draw.c" Line: 5603 in the method of TracePath().

Please tell me the workaround or solution to this problem.

Specifications of each server are as follows:

There may be something funny in your SVG file. Please put it somewhere like dropbox.com and paste the URL here. If it is small, just paste the contents between [ code ] and [ /code ].

[chanbuu]

Thank you for reply.

I converted the same SVG file on both servers.
On the local server , Converting to PNG worked well , but on the service server, didn't work well.

I wonder if my SVG file is funny.

I'm sorry but I can not upload my SVG file. this is highly confidential.

Your two versions of Imagemagick probably have different delegate libraries to deal with svg. IM can use its internal MSVG (XML), RSVG or Inkscape. Check

convert -list format

and see what is listed for SVG.

On the system that fails, it is likely just using the MSVG (XML) and on the system that works, it is likely using RSVG (or possibly Inkscape).

I entered this command on both servers.

Code: Select all

convert -list format

■Local Server
SVG -w+ Scalable Vector Graphics

■Service Server
SVG rw+ Scalable Vector Graphics (XML 2.6.26)

Will it be a result that is using IM's internal MSVG(XML) on the service server ?

I want to use RSVG on the service server.
What should I do to use RSVG.
Does a option of "./configure" command need ?

[fmw42]

■Local Server
SVG -w+ Scalable Vector Graphics

■Service Server
SVG rw+ Scalable Vector Graphics (XML 2.6.26)

Local server has no delegate to read SVG. But it can be written.

Service server is using IM internal MSVG (XML) to read the SVG.

You should install RSVG or Inkscape on both for better performance.

Incidentally, librsvg2, libpng and libjpeg are installed on each server in the following versions

Neither "n" or "u" are SVG 1.1 attributes. ( http://www.w3.org/TR/SVG/attindex.html ) I suspect the SVG file may have bigger problems than using atributes that don't exist.

A couple of things to try:

1. On the service server, "convert -verbose a.svg b.png" and paste all the output here.

2. Find a computer with Inkscape installed, and try to read the svg. If that works, then install Inkscape on the service server, and (with luck) everything will work.

3. Try to find the offending code in the SVG. Search for the strings n=" and u=" (Each string has 3 characters, and is probably in the SVG file with a leading whitespace.) If you have a generic XML reader, that could search for you. I'm not aware of an open-source XML reader, but they must exist.

4. Try editing the SVG file, either to cut it down to a minimal file that fails, or to remove the offending attributes.

thanks for reply!

I tried the follows command.

Code: Select all

convert -verbose a.svg b.png

output is:

Code: Select all

attribute not recognized: n
attribute not recognized: u
attribute not recognized: n
attribute not recognized: u
a.svg=>b.png SVG 2048x2048=>1024x1024 1024x1024+0+0 16-bit DirectClass 77.8KB 1.000u 0:01.000

However,I have re-installed with the option of "./configure" that is "-with-rsvg=yes".
Then, Error has been resolved.

But, Same phenomenon this problem( viewtopic.php?f=1&t=19006 ) has occurred.
How would you know what should I resolve.

[chanbuu]

The current output that is enterd "convert -verbose a.svg b.png" is as follows:

Why the difference or would occur in the result?
In the first place Service server, I'm getting worried about where the size of the original they've been recognized as 2560x2560.
I'm sorry If you have just heard
