no decode delegate for this image format `' @ error/blob

IMagick is a native PHP extension to create and modify images using the ImageMagick API. ImageMagick Studio LLC did not write nor does it maintain the IMagick extension, however, IMagick users are welcome to discuss the extension here.

Re: no decode delegate for this image format `' @ error/blob

What I was asking was if you could convert YOUR svg file in the command window. If you cannot, then it needs to be edited as per the comment by Bonzo. If it works fine, then I have two suggestions.

1) Forget Imagick and just use PHP exec to convert your svg file using the same command as per the command line

2) User readimage not readimageblob

Other than that, I do not know Imagick well enough to advise how to fix it.

My main goal was to be sure your Imagemagick worked and that you could read and write your svg file in the command line. Since both seem to work, the I assume it is your Imagick code that is faulty.

Sorry, I do not know how to install these for Linux. I am on a Mac and use MacPorts.

You listed
bzlib cairo freetype jng jp2 jpeg lcms lqr openexr pangocairo png ps rsvg tiff webp xml zlib
which shows you have rsvg and xml. RSVG should work fine for reading SVG files.

What do you get from

Code: Select all

convert -list format
for SVG

I have

SVG SVG rw+ Scalable Vector Graphics (RSVG 2.40.16)

If you can read SVG files and convert them fine in command line. Then Imagemagick is not missing anything. It is likely that Imagick cannot find the delegate library. Perhaps you need to put the full path to RSVG in your delegates.xml file.

Change

<delegate decode="svg" command=""rsvg-convert" -o "%o" "%i""/>

To

<delegate decode="svg" command=""fullpath2/rsvg-convert" -o "%o" "%i""/>

Or if you have Inkscape on your system, then do the same for


<delegate decode="svg:decode" stealth="True" command=""fullpath2/inkscape" "%s" --export-png="%s" --export-dpi="%s" --export-background="%s" --export-background-opacity="%s" > "%s" 2>&1"/>

Re: no decode delegate for this image format `' @ error/blob

Post by fmw42 » 2016-11-08T18:09:57-07:00

It shows

Code: Select all

SVG SVG rw+ Scalable Vector Graphics (RSVG 2.40.12)
So as I suspected, Imagemagick is fine and will be using RSVG which is installed.

So I guess it is Imagick that cannot find RSVG. Typically this could mean that you need to provide the full path to where you have rsvg-convert installed in your delegates.xml file. See my comments above. Imagick and PHP probably do not read the Unix $PATH environment variable, so you need to provide the full path to rsvg-convert in the delegates.xml file.

If that fails, then I am at a loss to know what else to suggest.

What is your platform? If Unix-based, then try

find /usr | grep "delegates.xml"
or
find /opt | grep "delegates.xml"

Sorry, then I have no further ideas. I am not an expert at configuring PHP/Imagick.

Where did you find the delegates.xml and what line did you edit and what does it now show?

I found problem!!
svg file text structure needs to be specified for readImageBlob to decode the file. Prepend <?xml version="1.0" encoding="UTF-8" standalone="no"?> to your variable having svg text.
