Extracing SVG data... from JPG
Posted: 2012-10-19T05:33:44-07:00
Hi IM folks,
My first post, not sure if I'm dealing with a bug or a feature - but to me it's a problem in any case.
I have been using ImageMagick for a number of years to extract SVG data from JPG files - the images concerned are JPEGs that have embedded paths created in Photoshop. Normally one would use TIFF or EPS to be able to utilise these paths, but my web app is able to extract the paths from the JPEG format, thereby allowing much smaller file sizes than EPS or TIFF. Unfortunately this feature stopped working on a recent install.
The command I use to retrieve the SVG data is
I then use regex to parse the output to create a TIFF mask from the SVG data.
This is working perfectly on CentOS 5.5, ImageMagick 6.6.7-2
It is NOT working on CentOS 5.8, ImageMagick 6.6.5-10
On the latter version, it IS possible to retrieve the SVG data if the file is a TIFF, but not when it's a JPEG.
A sample image is available here: http://198.101.244.68/testsvg.jpg
The configuration details for the two installs are below.
Any help greatly appreciated!
Pier
