Description:
When user adds a picture from gallery as a contact photo, cropping it in the picture chooser (from contacts) results in contact photo displaying as an all black image.

User must crop photo to the smallest size allowed by selector. This only seems to work with photos that are wider than they are tall.

Repro Steps:
1) Update a Flame to 20150528143550
2) Launch contacts app and tap to edit an existing contact
3) Tap to change or add photo to contact with gallery as source
4) Crop photo to smallest possible size and press done

Actual:
All of the contact picture is a black square.

Expected:
Contact picture is displayed as cropped.

Issue does NOT reproduce on Flame 2.2

Contact picture is displayed as cropped, no black areas visible in picture.

[Blocking Requested - why for this release]:

This is a bad regression from 2.2 so nominating this 3.0?

Hei Wilson, do you think we are getting the image correctly from the gallery?

I know :djf has been having issues with image decoding in Gecko recently so he might have some clues.

	Comment 6 • 9 years ago

There was a gecko change recently (Seth probably has the bug #) where in low memory situations, canvas.drawImage() (used for cropping) doesn't decode the image and just draws a black rectangle.  In 2.2 it throws an exception instead.

Brogan: A few questions for you about this bug. (1) Does this only occur on a 319mb flame? (2) Is the photo you're seeing this bug with an ordinary photo taken on the Flame? If not, would you attach it please? (3) Would you check this on 2.2 again? I wouldn't expect to see a black image on 2.2, but instead some other kind of failure, like the inability to pick a cropped contact photo at all. (4) Can you reproduce this bug when picking and cropping an image from the SMS app instead of the contacts app?

If there are symptoms in 2.2 then this may be related to bug 1166136. If it really is 3.0, then it may have something to do with the changes made for Aries to remove image size restrictions that are still needed for low-memory flames.

In any case, I'm pretty sure it is a gallery bug, not a contacts bug. I'll take it and make sure it goes away when the other stuff gets fixed, too.

Issue appears to occur due to changes made in Bug 1064600

Addiontal Note: In later builds cropping images to as small as possible will have the image appear as black. Moving further back the image will appear blank. I did not trace exactly when this difference occurs but thought it was worth mentioning although I believe it to be the same issue.

	Comment 9 • 9 years ago

Issue reproduces in 512 as well, cropping image as described in comment 0 results in an all black image being displayed for contact.

Issue does not reproduce with images taken with device camera (attached an example affected image.)

As per comment 7 the issue does reproduce on Flame 2.2

Different issue occurs in SMS app (see bug 1169680)

Upgrading to smoketest blocker, as this blocks case https://moztrap.mozilla.org/manage/case/10742/ now that bug 1169680 is resolved.

	Comment 11 • 9 years ago

Hi David, wondering about the status of this bug- this is a smoketest blocker that made us to disable OTA. If jdarcangelo thinks the Comment 7 shows the cause for this bug, can we back out or add a quick fix?  It's been open since the beginning of this week so we need to have it resolved asap.  Thanks!

	Comment 12 • 9 years ago

Setting NI? for Punam to take a closer look as I'm low on bandwidth at the moment. The patch in question landed over 7 months ago and I just skimmed through it and don't see anything obvious that might cause this.

	No-Jun Park [:njpark]
	Comment 13 • 9 years ago

Peter, could you double check the regression range in Comment 7?  the range is in build 36, and I don't think we didn't know about this bug for that long, (as you know, we're currently in 41) especially when 2.2 is unaffected.

	Peter Bylenga [:PBylenga]
	Comment 14 • 9 years ago

We were counting it as a ST for a MMS case, perhaps the root cause is the same but was exposed at different times per app?  Also it's only happening with certain files instead of being a global issue. Because of these reasons going to denom as a smoketest.  This is still a 3.0+ and should be fixed.

	Punam Dahiya [:pdahiya]
	Comment 15 • 9 years ago

I am able to replicate the issue with attached image and not with image taken from Flame camera. This issue is seen for all cases where pick activity is used  (via contacts or Messaging app). 

Device used: Flame-kk 319 MB

Error seen in logs

06-12 05:48:52.395 E/Gallery ( 3421): [JavaScript Error: "Image corrupt or truncated." {file: "blob:app://gallery.gaiamobile.org/6802fef1-d4a1-46b7-9d79-bb13bb8a6c1f#xywh=1594,1228,2099,2007" line: 0}]

which indicates we are using #xywh media fragment to crop while decoding for this image. Will continue to investigate further and update  with findings.

	Punam Dahiya [:pdahiya]
	Comment 16 • 9 years ago

On Flame-kk 1024 MB this bug is not seen and I can successfully see cropped picture added to contacts indicating this bug is happening only in low memory for attached image.

	David Flanagan [:djf] Assignee
	Comment 17 • 9 years ago

The test image is 20 megapixels, which is a pretty unrealistic test case for the Flame. I don't think this needs to be a smoketest blocker.

In comment #6 I said I'd take the bug and investigate, but apparently I didn't actually take it, and I forgot about it.  I am taking it now.

Punam's comment #15 is a good clue.  I could swear that #xywh used to work. Seth tells me that it never has worked and never will.  Certainly it does not work today. If I modify crop_resize_rotate.js so it does not use #xywh, then it will be forced to use #-moz-samplesize intead, and that will probably fix this.

	David Flanagan [:djf] Assignee
	Comment 18 • 9 years ago

It turns out that hte #xywh error message is a red herring. The cropResizeRotate() function only falls back to #xywh if it is not going to use #-moz-samplesize. So even if I get rid of #xywh (which I should do since it has never worked and probably never will) we will still have the bug which is that we're failing to downsample the image before cropping it.

The problem is that in the pick activity code we are not passing a maximum size to cropResizeRotate(). The problem may well be with bug 1064600, since we did refactor that code into pick.js in that bug.

	David Flanagan [:djf] Assignee
	Comment 19 • 9 years ago

Okay, here's what happened. 

- I began work on bug 1064600

- I fixed the issue in this bug as part of bug 1065887

- Justin took over my patch in bug 1064600.  That patch had already copied the bad code from gallery.js to pick.js, so it would have been very tricky to notice the merge error and fix it correctly.

So basically, this issue was fixed once, but then we accidentally broke it again with bug 1064600.

Patch coming up.

	David Flanagan [:djf] Assignee
	Comment 20 • 9 years ago

Punam,

This patch restores code that was added in bug 1065877 to limit the maximum image decode size when cropping images picked during the pick activity. It actually makes it more aggressive than it was in 1065877 because I was still seeing failures when I just restored the old code.

Also, the patch adds code to use maxFileSizeBytes from the pick activity as a hint about the desired output size. Contacts and Messages set this parameters in their pick requests, and using it dramatically reduces the size of the images we return, which is a good thing for all of the apps.

This bug has been verified as "pass" on latest Nightly build of Flame v3.0 by the STR in Comment 0.

Actual results: Adding and cropping the example image provided in Comment 9, then saved as contact picture, it displays cropped photo normally.
