Add a requirements check for GD support of allowed image types

I am seeing the same issue, which is preventing my system from generating Image Style instances.

I face the issue with Drupal 9.0.1 and PHP 7.4.
Any solution?

My issue seems to be specifically tied to php 7.4. I opened this other issue about it, and the errors went away after I downgraded to php 7.3.

Strange, it's said that Drupal9 will be supported by PHP 7.4.

yeah, I know, I'm very confused by it as well. I;m on Drupal 8.9.1 by the way.

Tried to downgrade into 7.3.
It caused the error.
TypeError: Argument 2 passed to Symfony\Component\Routing\RouteCollection::add() must be an instance of Symfony\Component\Routing\Route, bool given, called in /mnt/www/html/midlandsbdev/docroot/core/lib/Drupal/Core/Routing/RouteProvider.php on line 382 in Symfony\Component\Routing\RouteCollection->add() (line 74 of vendor/symfony/routing/RouteCollection.php).

This one fixed that issue.

But the original issue with PHP 7.4 still remains.

That's weird... I had the issue on 7.4 and resolved it by downgrading to 7.3...

Possibly? https://stackoverflow.com/questions/49891991/warning-imagesx-expects-par...

Is GD support for JPEG there on this PHP build?

#10 actually in the requirements we are testing if the gd extension is enabled, but not if specific image formats are supported, and that is a gap IMHO because some PHP builds may miss linking the relevant libs. The only format explicitly checked for is PNG, but the check is in the color (!) module requirements. See also #2340699-111: Let GDToolkit support WEBP image format for similar discussion on supporting WebP image format.

Re #11. I was wondering about that. After the OPs check in, let's consider re-framing this issue as a requirements logic improvement if no issue exists.

Also GDToolkit::load doesn't seem to have a good way to signal failure.

So, #10 may actually be my issue as well. I am using pantheon, and their 7.4 does not have JPEG support, but their 7.3 does. Thanks for the suggestion @cilefen!

For those on Pantheon as well, their engineering team is working on resolving this. I'll post back when its done.

I think #11 is a great suggestion.

As a task this may be a duplicate.

for what it is worth, Panthon updated their 7.4 environment to include JPEG support for GD. Unfortunately, running this updated environment that used 7.4.3, the issue persists. I can upload and render (create Image Styles) for PNG files no problem, but the JPEG files still present issues:

Unable to generate the derived image located at public://styles/scale_and_crop_thumbnail_square_85x85_/public/research_equipment_pictures/aphex2_0.jpg.

Image scale and crop failed using the gd toolkit on public://research_equipment_pictures/aphex2_0.jpg (image/jpeg, x)

this is a critical issue that prevents using Drupal on 7.4. As 7.3 will hit its end of life relatively soon, I'm wondering if this issue merits having it's priority increased.

Did Pantheon in the end add support for JPEG in GD? Drupal could test for library support in the related issues (as I've titled this one, it is probably a duplicate—so I retitled it to be more like a bug). But I don't know how Drupal could work around a missing GD library. Any ideas?

Sorry @cilefen, I typed a reply to you days ago and must have never submitted it.

yes you can review the Pantheon 7.4 env here, and it does now support JPEG with GD. However, despite upgrading my Pantheon 8.9.2 site from 7.3 to 7.4, I am still seeing the errors in #18.

I had to downgrade back to 7.3 to prevent error.

I think GDToolkit::load returns false and never sets the resource property. Is imagecreatefromjpeg, from GD, a global function on that new PHP build?

Could you use ImageMagick temporarily?

Hey @clefen, unfortunately I have no control over Pantheon, so I can't easily test those packages. But, since 7.3 works and 7.4 doesn't, can you spot any difference in those separate phpinfo outputs that might indicate the issue here?

They were configured for compilation differently. In 7.3 the flag is --with-jpeg-dir=/usr but in 7.4 it is --with-jpeg. But I assume that is for a reason. Ask support if function imagecreatefromjpeg exists in their PHP 7.4 container.

Awesome, I will look into it @cilefen and get back to you, I really appreciate it!

@cilefen, I just received this from Pantheon:

We do have the imagecreatefromjpeg function available - I confirmed on my test site - https://epz.io/script.php - Though there is an error displayed, you'll see it's not related to the function itself not being available, but rather an issue with the input I've provided it. I just placed this script in my /web folder:

echo "hello world";
$resource = imagecreatefromjpeg('sites/default/files/2020-04/drupal.jpg');
print_r($resource, TRUE);
echo "Current PHP Version: " . phpversion();

🤷‍♀️

The stack trace you posted in the issue summary indicates two things. First, that imagesy was passed a resource but it "is not a valid Image resource":

#2 /DOCUMENTROOT/code/core/modules/system/src/Plugin/ImageToolkit/GDToolkit.php(343): imagesy(Resource id #11)

But then, this runtime warning suggests that ::load did not return anything:

Warning: imagesx() expects parameter 1 to be resource, null given in Drupal\system\Plugin\ImageToolkit\Operation\gd\Resize->execute() (line 67 of core/modules/system/src/Plugin/ImageToolkit/Operation/gd/Resize.php).

Ostensibly someone could build a minimal reproduction on a clean Drupal install on Pantheon and hand that off to support.

@cilefen, so are you confident that this issue is likely the result of the Pantheon environment, as opposed to drupal/GD/7.4/etc? if so I will reproduce there and ask them to investigate. Thanks again for the helpful insight.

It is not reproducible with Homebrew PHP 7.4 by uploading a jpg and creating jpg variants. Incidentally, Homebrew's compiled-in GD jpeg support is:

JPEG Support enabled
libJPEG Version 9 compatible

hey @cilefen, I worked with Pantheon to try to reproduce in their 7,4 environment. I wasn't able to, so maybe I just didn't test properly after they fixed their 7.4 environment. I can't say, but hopefully I just screwed something up and this is no longer an issue with pantheon 7.4 or my system. If the issue resurfaces, I will post here. Thanks very much for the help, I really appreciate it.

Thanks for the follow-up. I am moving this back to a support request because the title now sounds like a statement of fact ;-).

This is not a Pantheon only issue, Acquia also has issues with PHP 7.4. I had to downgrade to PHP 7.3 to temporarily fix the issue. Seems to be an environment issue.

@jedgar1mx Did you report it to them, and reference this issue?

I reported it to acquia awhile back and it seems they will be doing some updates to their platform. I just found this issue while looking for some other stuff. Figured I should let acquia users know 🙂.

Acquia lists it as a known issue at https://docs.acquia.com/cloud-platform/known-issues/#some-image-formats-... and support clarified the cause to be PHP 7.4 doesn't have jpg and png support compiled into the GD library. We are on D7 and experienced it.

If you are using docker, you can build your GD library with JPEG using the following lines:

RUN apt-get update \
    && apt-get install -y libpng-dev libjpeg-dev libfreetype6-dev
RUN docker-php-ext-configure gd --with-jpeg --with-freetype \
    && docker-php-ext-install gd

This way GD is compiled and enabled with libjpeg and the problem is solved.

The fix has been deployed on Acquia.

This patch add requirements check for the existence of the image functions for the format supported by the GD toolkit.

I am able to solve this issue by adding below configuration to docker file.
This works with PHP 7.4 and Drupal 9 for GD issue

apt-get update; \
apt-get install -y --no-install-recommends \
build-essential \
libfreetype6-dev \
libjpeg-dev \
libpng-dev \
libpq-dev \
libzip-dev \
libjpeg62-turbo-dev \
# GD
docker-php-ext-configure gd --enable-gd --with-freetype --with-jpeg --with-webp; \
docker-php-ext-install -j "$(nproc)" \
gd \
; \

Getting this in the db log:

Notice: Undefined index: severity in color_requirements() (line 38 of /var/www/d91/core/modules/color/color.install)

Never mind #43... I was running an old patch. Sorry for the noise.

Rerolled and cleaned up after commit of #2340699: Let GDToolkit support WEBP image format. Changed to MR workflow.

Added 2 comments and it looks mostly great!

Thanks for review @andypost, fixed your points.

I have the same issue on PHP 8.0 and Drupal 9.3.12

Bumped the MR target branch and rebased.

Thanks @heddn, merged your suggestions

Rebased for 10.1.x, and at this stage dropped the changes to the color module that it's better be left alone since it is up for removal in D10.

Working on adding a kernel test.

Needs CS fix but overall looks great!

Tagging for usability review as if GD library missing more then one format it could look weird

Would be great to add screenshots about how it may look

PS: thinking about contrib module /project/imagemagick which using convert CLI command - how it may change the message for supported formats

Screenshots taken from the status report page:

ALL GOOD

One format missing

Two formats missing

Thank you! That's what I mean when more then one format is missing

I find it more readable if it will be one-liner - The GD library was compiled without following formats: JPEG, WEBP. Check the...

Added commit to fix #63

Thanks, did some more cleanup, we would need new screenshots now.

New screeshots:

One format missing

Two formats missing

IMO it's ready to go but still needs UX POV on it and wording

When you tag an issue for usability review, please make it easy for the usability team to review the issue. Update the issue summary:

• The "Proposed resolution" section should describe all the changes made in the issue.
• The "User interface changes" should show the existing UI and the proposed UI.

Most of the time, I prefer to have plain text in the "Proposed resolution" section and screenshots in the "User interface changes" section.

You can also attend the weekly usability meeting to present an issue.

I am adding the tag for an issue summary update and setting the status to NW.

Honestly I think usability review here is a bit of an overkill, but updated IS according to #71 anyway.

Thanks.

We've discussed the issue at #3296084: Drupal Usability Meeting 2022-07-15. That issue will have a link to a recording of the meeting. For the record the attendees at todays (07-15-2022) usability meeting were @benjifisher, @shaal, @simohell, @worldlinemine, and me.

There was a consensus that it is useful feature. We would have two suggestions in regards of the scan-ability of the micro copy. Currently it reads for one file format missing:

Supported image file formats: JPEG, PNG, WEBP. 
The GD library was compiled without the support for the GIF image format. Check the PHP GD Installation documentation for information on how to correct this. 

for two image formats missing:

Supported image file formats: PNG, WEBP. 
The GD library was compiled without the support for the following image formats: GIF, JPEG. Check the PHP GD Installation documentation for information on how to correct this. 

The information of interest are the supported image file formats. That is easily scan-able. You have the keyword Supported and then there is the visual queue of the italic file format list. That's good.
If the user wants to know the unsupported file formats he or she first has to scan the bits about GD library, compilation and so forth until the points of interest, the unsupported file format(s) could finally be found.
The other detail is the end of the second sentence about how to correct which implies that something is wrong. But perhaps the selection of file formats was a conscious decision. We would suggest the following pattern:

one file format missing

Supported image file formats: JPEG, PNG, WEBP. 
Unsupported image file format: GIF. 
Check the PHP GD Installation documentation if you want to add support for this format.

two image formats missing:

Supported image file formats: PNG, WEBP. 
Unsupported image file formats: GIF, JPEG. 
Check the PHP GD Installation documentation if you want to add support for these formats.

That way you have the identical easy to scan pattern for the supported as well as unsupported image file formats. The description about the unsupported file formats gets shorter and more concise - you provide the link to the documentation for those interested and or necessity how to add support.

I'll set the issue to needs work and remove the needs usability review tag.

Thanks a lot team for the review.

I made changes to the MR according to the feedback.

Updated IS with latest screenshots.

I find it ready to go

Added a review to gitlab

Made the suggested fixes.

Suggestions addressed, let's get it in

I think we can have less reliance on array keys and more rely on PHP constants. See code review above & in gitlab

Made fixes according to @alexpott's input. Thanks!

It looks rtbc but I'm curious about to define array of formats as enum, so when we'll add avif format it will need to change less places

OK, but I wouldn't hold on that... otherwise this becomes a never ending issue...

All the code changes look good to me.
All the points of @alexpott have been adressed.
The IS is in order.
For me it is RTBC.

Backported this to 10.0.x because it is a task that is a pure addition and useful. Didn't backport to 9.5.x because it has a PHP 7.4 feature...

Committed and pushed 00d6bd97a7 to 10.1.x and ee88d7a711 to 10.0.x. Thanks!

There is a proposal to change this check in #3570466: Reduce severity of GD library supported image file formats warning. Please review and comment.
