Bug 201982 – [GTK][WPE] EXIF orientation tests are failing since added in r249364 - "EXIF orientation should be respected when rendering images"

• Status: NEW
• Component: WebKitGTK

[Miguel Gomez]

These are the tests failing both for WPE and GTK.

fast/images/exif-orientation-background.html [ ImageOnlyFailure ]
fast/images/exif-orientation-canvas.html [ ImageOnlyFailure ]
fast/images/exif-orientation-composited.html [ ImageOnlyFailure ]
fast/images/exif-orientation-content.html [ ImageOnlyFailure ]
fast/images/exif-orientation-element-object-fit.html [ ImageOnlyFailure ]
fast/images/exif-orientation-element.html [ ImageOnlyFailure ]
fast/images/exif-orientation-image-document.html [ ImageOnlyFailure ]
fast/images/exif-orientation-image-object.html [ ImageOnlyFailure ]
fast/images/exif-orientation-svg-feimage.html [ ImageOnlyFailure ]
fast/images/exif-orientation-svg-image.html [ ImageOnlyFailure ]

These is the output of one of the tests that shows the problem:
https://build.webkit.org/results/WPE%20Linux%2064-bit%20Release%20(Tests)/r250087%20(15371)/fast/images/exif-orientation-element-diffs.html

Seems that we are not calculating the proper width and height for images rotated 90 degrees CW and CCW.

New EXIF related tests are failing showing the same kind of error message: "EXIF orientation should be respected". The tests are the following:

Since added in r253610:

* fast/images/exif-orientation-webgl-texture.html

Since added in r254187:

* fast/images/image-orientation-dynamic-from-image.html
* fast/images/image-orientation-dynamic-none.html
* fast/images/image-orientation-none.html

[Diego Pino]

More EXIF orientation related tests are failing since added in r254841:
 
  * fast/images/exif-orientation-background-image-no-repeat.html
  * fast/images/exif-orientation-background-image-repeat.html
  * fast/images/exif-orientation-border-image.html

[Lauro Moura]

This is also affecting fast/images/image-orientation-none-canvas.html from bug209849.

[Diego Pino]

Passing since r260016 (https://trac.webkit.org/changeset/260050/webkit):

  fast/images/image-orientation-dynamic-none.html
  fast/images/image-orientation-none.html
  fast/images/image-orientation-none-canvas.html

Lauro fixed most of these (but not all) in bug #95299.

Thanks for applying #95299, Michael (did not have time due to other issues). It's on my table today to update what's missing from that bug.

fast/images/exif-orientation-background-image-repeat.html
is still a failure, expectation may need to be set to clear up dashboard until this issue is resolved

Downstream bug report using WebKitGTK 2.36.0:
https://gitlab.gnome.org/GNOME/evolution/-/issues/1897

it includes a sample image, if needed.

I see this is marked as WPE; I'm not sure it's related for the evolution bug.
