Misplaced rasterized SVG elements

[razor7]

Hi, iḿ using this little chunk of code to convert from SVG to JPG using IMagick API.

The code works flawlessly, but the rasterized JPG got some elements misplaces (I tthink that the rotated ones only)

This is the code

Code: Select all

<?php



$usmap = '/www/docs/.com.ar/public_html/presugen/export/svgGenerado.svg';

$im = new Imagick();

$svgin = file_get_contents($usmap);



$im->readImageBlob($svgin);



/*jpeg settings*/

$im->setImageFormat("jpeg");



$im->writeImage('/www/docs/.com.ar/public_html/presugen/export/svgRasterizado.jpg');/*(or .jpg)*/



$im->clear();

$im->destroy();



?>

I have attached the SVG file, that loads OK in InkScape

svgGenerado.svg.tar.bz2

(37.04 KiB) Downloaded 1304 times

and this is the rasterized image

svgRasterizado.jpg (29.69 KiB) Viewed 19956 times

Also tested with commandline "convert" but same result.

Please advise, is the last think to finish my project.

Thans a lot!

You may be using the internal SVG renderer which is not as good as the librsvg delegate library. We're using ImageMagick 6.7.1-5 and get correct results. This command:

• identify -list format

returns

• SVG SVG rw+ Scalable Vector Graphics (RSVG 2.32.1)

which shows SVG images are rendered with the librsvg delegate library.

OK, what i have to ask to my share hosting provider? Do the need to install something?

Thanks a lot!

Sure, you need to install librsvg2 and librsvg2-devel then rebuild / reinstall ImageMagick.

Well, I tryed it on my ubuntu PC issuing theese commands

$ sudo apt-get remove imagemagick
$ sudo apt-get install imagemagick librsvg2-bin

But when i run $ identify -list format i still get

...
SVG SVG rw+ Scalable Vector Graphics (XML 2.7.6)
...

The ImageMagick RPM is already built without RSVG support. You need to download and build ImageMagick from source. Install ImageMagick-devel and then download ftp://ftp.imagemagick.org/pub/ImageMagi ... 1-6.tar.gz. Now type

• tar xvfz ImageMagick-6.7.1-6.tar.gz
  cd ImageMagick-6.7.1-6
  ./configure
  make
  make install

So firt thing to do is install librsvg2 and librsvg2-devel, then uninstall current imagemagick and then download, compile and install im, thats right?

Sounds about right. Have fun.
