Not all image edits are applied to all subsizes

[mitogh]

When editing an image using the admin editor, not all edits are applied correctly to all image subsizes. Specifically, the problem occurs when an edit results in a smaller size than the defined image size. Given the following image subsizes, and the attached image.

=> array(6) {
  ["thumbnail"]=>
  array(3) {
    ["width"]=>
    int(150)
    ["height"]=>
    int(150)
    ["crop"]=>
    bool(true)
  }
  ["medium"]=>
  array(3) {
    ["width"]=>
    int(300)
    ["height"]=>
    int(300)
    ["crop"]=>
    bool(false)
  }
  ["medium_large"]=>
  array(3) {
    ["width"]=>
    int(768)
    ["height"]=>
    int(0)
    ["crop"]=>
    bool(false)
  }
  ["large"]=>
  array(3) {
    ["width"]=>
    int(1024)
    ["height"]=>
    int(1024)
    ["crop"]=>
    bool(false)
  }
  ["1536x1536"]=>
  array(3) {
    ["width"]=>
    int(1536)
    ["height"]=>
    int(1536)
    ["crop"]=>
    bool(false)
  }
  ["2048x2048"]=>
  array(3) {
    ["width"]=>
    int(2048)
    ["height"]=>
    int(2048)
    ["crop"]=>
    bool(false)
  }
}

The defined sizes above are the ones coming by default with the setting provided below.

Steps to replicate the problem:

1. Upload the image into your installation.
2. After the image is uploaded, click on edit to open the image editor or go to the image editor from within the media library.
3. Click on Edit image
4. Click on rotate image (either right or left) only once.
5. Make sure the changes are applied to all images by checking that the setting Apply changes to: All image sizes is set
6. Click on save

After the image is saved observe the changes were applied only to the following image sizes:

• thumbnail
• medium
• large
• full

The only size that was not updated as expected was:

• medium_large

Good catch @mitogh! Looks like some conditional checks for in image-edit.php aren't working as expected.

In my testing this happened when the i rotated to the vertical position. rotating again and saving my medium_large size was correctly edited. flipping images always seemed to work. cropping worked until i tried a vertical thin crop, then some sizes were saved and others not.

[mitogh]

Right, it seems like the issue happens for rotation specifically on images that do not have dimensions like a landscape or portrait image if is rotated the dimensions are different, flip works normally on my end due to the image dimensions are not modified from the original image.

Let me know in case you have any additional questions. @adamsilverstein, thanks for taking a look and replicating the steps for this issue.

If time allows I can try to find a patch for this one as well.

Hi there, welcome back to WordPress Trac! Thanks for the ticket.

Just noting that I was able to reproduce the issue with the steps described. I was also able to confirm comment:1.

[mitogh]

I've added a patch with a suggested fix. The suggested fix follows the same approach as WordPress follows when the image is uploaded for the first time, this approach is basically that when an uploaded image is smaller in dimensions than an image size the image size is not created for the image, which was the case for this image when the image Was rotated it was smaller in dimensions that the failed size creating an error and not saving the edit.

As described this approach would not save any image that was errored out by the editors, images would remain in the backup sizes and can be restored at any point in time, by rolling back an existing size.

The function wp_get_additional_image_sizes was replaced with wp_get_registered_image_subsizes in order to have a more accurate access to the defined image sizes by the user.

Cast of values to int was introduced as well in order to make sure settings (as strings) were converted to integers.

Per the discussion in the bug scrub, this still needs-testing, needs-unit-tests and a review to ensure no BC breaks are introduced. Moving to the 6.1 milestone.
