Webp conversion broken with ImageMagick 6.9.10-68 Q16 x86_64 2019-10-07 and PHP Plugin

[photogaz]

Since ImageMagick 6.9.10-68 Q16 x86_64 2019-10-07, converting to webp no longer works with the PHP plugin.

This happens on both of my servers.

The webp converts but the file is just a blank transparent image.

There are no errors reported.

Edit: it seems to only be when I add any manipulation to it.

e.g.

$img->cropThumbnailImage($image_size, $image_size);

[magick]

Try this command on the command-line:

Code: Select all

convert logo: -thumbnail 100x100 logo.webp

Can you read/view logo.webp? Hope so, that command works fine for us and produces a valid image in the WebP image format. If it fails, post a link to the image so we can inspect it and also post the results of this command:

Code: Select all

convert -list format | grep WebP

[photogaz]

That doesn't work here in straight command line.

It produces the blank image, see link below:

I tried it on my other server install with older ImageMagick 6.9 builds and it works fine.

Using convert -list format | grep WebP shows:

Code: Select all

 WEBP* WEBP      rw-   WebP Image Format (libwebp 0.4.3 [0202])

I also just removed 6.9 and installed 7.08 build 68 and it works fine. So it just seems isolated to 6.9.10-68. FYI 6.9.10.67 also has the issue, but prior to that it's ok.

The min version of libwebpmux is 0.4.4. Any chance you can upgrade your library and let us know if that fixes the problem?

Sure, I just ran the libwebp check on our CentOS 7 server which has a newer libwebpmux,

convert -list format | grep WebP returns:

Code: Select all

WEBP* WEBP      rw-   WebP Image Format (libwebp 1.0.2 [020E])

It has the same issue as our CentOS 6 server where the webp output is a blank image.

Ok, we can reproduce the problem now. We should be able to fix the problem and export a new release by late this weekend.

That's great, brilliant news.

Thanks so much for your hard work.

Just to let you know that the Version 7 I installed has an issue too. Not sure if it's the same issue but instead some of the image comes through but is corrupted.

See example:

Just thought I'd let you know in case V7 wasn't in your fix process.

Will this get pushed to Beta or full release when fixed?
