KNOWN ISSUE: problem with picture - support webp

[MaudeFJ]

Team:
ISSUE: images changed from being the actual image to a pure white image at some point.

Maude added some events (Here is a link to them) last week and added the image displayed below. However, when she checked back the image that appeared was a white image (not the image she added). Can you please check the logs to see what happened?
Note, she updated the image today, August 13th at around noon. The events were created at two different times, one in July, the other two August 7th.
Best guess is the issue happened sometime between August 7 and august 12.

Original request from Maude

This looks like an image server issue:

This image URL is returning a blank image.

The URL displays almost a blank screen however, the image in S3 is good. I could not find anything interesting from the image server's log.

S3 URl: s3://footlight-images/05566315-fb72-4167-8d0b-4820938a86c1.jpg
CMS: https://cdn.footlight.io/iiif/3/05566315-fb72-4167-8d0b-4820938a86c1.jpg/full/max/0/default.jpg

@saumier Lets discuss this in detail today.

[sahalali]

The image looks like something other than jpeg. Can you please provide the original image uploaded?

[MaudeFJ]

[MaudeFJ]

These are the 2 pictures i have in my files

[troughc]

@sahalali please see Maude's images.

[MaudeFJ]

I dont know if this is related but i also have a prob with those pic..

Action item:

1. File a bug in cantaloupe project

The CMYK JPEG images are not supported currently supported by cantaloupe server.

[troughc]

Action: Add an message informing user that uploaded image is not supported (pop-up in english and french UIs) that blocks user from adding unsupported image formats.
Caitlin to add message text here - after we determine what approach to take. Potential message will be something like this:
CMYK images are not supported. Convert the colour space to RGB before uploading or choose a different image.

[AbhishekPAnil]

cc @AbhishekPAnil will explore the available packages for converting various image formats to JPEG.

[saumier]

Some feedback for this issue. Please check for support in image server for these formats like .webp. The manipulation of images is the responsibility of the image server. For maintenance and support it makes sense to support more image formats if they can be supported by image server rather than add exceptional conversion code in our CMS code.

[troughc]

First line of attack: please find out if we can support this format. (webp) in the image server.

[saumier]

Note: The format .webp is being used by about 15% of websites according this website
https://w3techs.com/technologies/details/im-webp#:~:text=WebP%20is%20used%20by%2014.4%25%20of%20all%20the%20websites.

[troughc]

@sahalali please take this one up.

[dev-aravind]

@sahalali Assigning this to you as the development part is completed. The PR can be found here.

[troughc]

Note: webp images will be converted to jpeg, which will resolve this issue.

@dev-aravind Please add link to issue of Cantaloupe. Thx.

[sahalali]

There is an open issue in the Cantaloupe project to add support for WebP format images.
cantaloupe-project/cantaloupe#710

[saumier]

@sahalali Thx for the link to cantaloupe#710.

I looked at the description and it is related to exporting WebP format not inputing WebP. The example given is /iiif/2/tq%2F566%2Fym%2F4557%2Fargo-logo.jp2/full/802,/0/default.webp which outputs default.webp. Our use case is for the Cantaloupe server to input a WebP and output a default.jpg for display in the CMS or website of our clients.

Can you check again for that? Co-pilot is telling to add processor.webp = Java2DProcessor to the cantaloupe.properties file. And if that does not work then to check if we have

<dependency>
    <groupId>com.luciad</groupId>
    <artifactId>webp-imageio</artifactId>
    <version>0.2.0</version>
</dependency>

@sahalali @saumier I found the issue with the webp images that mentions support in the earlier version. Please have a read and let me know what you guys think.

Also @saumier I tried the solution in your comment but it seems like the code for webp support is missing.

[troughc]

@MaudeFJ we found a way to support these types of images (webp) -- we are converting them to JPEG further upstream from the CMS. Our approach may change in the future, but the issue is fixed and should no longer be happening.
Closing this issue.
