There is currently no way to add an image mime type to the clipboard data for a copy event in Chrome. To support copying raw image data in Docs, it would be useful to add support for jpg, png, gif, tiff, and bmp image formats.

Any estimates when this could land?

estade, would you know who might be a good person to direct this to?

dcheng is the right person afaik

Alright, I'll have to bother him for updates then :)

dcheng, have you been able to make any progress?

I've been busy with other work items unfortunately. Here's what I think would need to be accomplished to get this implemented though:

Investigation of:
- Windows support. I found http://msdn.microsoft.com/en-us/library/aa359736(v=vs.85).aspx on MSDN, but it seems to just be MIME types. http://msdn.microsoft.com/en-us/library/windows/desktop/dd145023(v=vs.85).aspx seems to indicate that it's possible to stuff PNG/JPG compressed data into bitmaps at least... but I haven't tried to see how well it works.
- Mac support. I think OS X 10.6+ support a nicer way to write images to the clipboard... but we support 10.5, so we always write the image out as a TIFF.

Understanding requirements:
- We don't want to transcode pictures, right? So if a page places JPG in the clipboard, we need to make sure the same bits that we write to the native clipboard come back to Chrome.
- Is it OK that only image/jpg (and maybe image/bmp) are available if you set a image/jpg to the clipboard?
- What about native apps? As highlighted above, Windows doesn't have the best support for compressed formats and there don't seem to be native clipboard formats for compressed images. As a consequence of this, to get copy jpg -> paste in Paint to work properly, it seems like we'd need to place a decompressed bitmap in the clipboard as well.
- Anything else I'm missing?

Got it. Do you think you'd be able to get to it soon, or is there someone else who might be able to take it on?

I'm happy to provide help in the form of design/code feedback, but you would have to find someone else to drive this. Sorry =(

Do you have any suggestions for people? I'm unfortunately unfamiliar with the area.

Ping on this again.

Hi folks, thanks for your interest in this issue. Unfortunately, just adding supporting comments without any extra substance only produces extra noise for our developers to wade through.

If you're interested in seeing this bug fixed, please feel free to star this issue. Thanks!

Re-assigning to dknox for eventual owner finding as dcheng doesn't have cycles to drive this.

Assigning to Saswat since he's currently looking for an owner in CrOS.

Qiang will be our new eng owner with consultation from dcheng@

#50 -
Sorry, but how come this is considered as fixed?
- The original request was to be able to copy images to the clipboard in web pages (not extensions).
- The original request applied to all of the platforms, not Chrome OS.

Please, do not piggyback on web platform bugs/feature requests for extension API implementations.

Please, reopen this.

Per #50, I'll reopen the issue. I'm happy to watch over it, as I inherited DataTransfer from dcheng.

I think the work in #48 is important and a good step forward. However, as #50 mentioned, it is not (yet) applicable to the Web platform. Perhaps it is worth opening a different bug to track launching the extension API?

FWIW, I also considered repurposing this bug to represent the extension API work, but that didn't seem appropriate, given the high number of stars. I imagine that the people who starred the bug want to track the work of adding image copying support to the Web platform.

I have filed a separate https://crbug.com/chromium/678794 for the solution we had on chromeos only.

[Empty comment from Monorail migration]

+lgarron, +dahlke

Jon - IIRC, wasn't someone on your team going to be looking into this for the whole web platform?

[Empty comment from Monorail migration]

https://crbug.com/chromium/678794 was an extension API for it.

Asynchronous clipboard (https://crbug.com/chromium/593475) will allow copying images on the open web.

[Empty comment from Monorail migration]

[Monorail components: -Blink>Editing]

Marked as WontFix.

I did the following steps:
1: Right click on an image on a web papge
2: Select "copy image" from context menu
3: Paste to Gmail composer / Google docs
And then the image appeared as expected.

Please correct me if I'm missing anything here.

This bug is for allowing a JS copy event handler to write an image to the clipboard.

[Empty comment from Monorail migration]

[Empty comment from Monorail migration]

dcheng@ and phistuck@, thanks for clarification. Update summary makes us to have clear idea.

So, we need to do two thing:

blink
- DataTransferItemList::add(data, type) to accept image/{jpeg,png,gif,...}
- DataObjectItem to support blob with mime type

content and ui
- Pass mime type w/ blob to renderer process to browser process
- Write blob to clipboard w/ platform specific image type based on mime type

Is this list correct?

Here current flow of writing image to clipboard:
1. blink::Pasteboard::writeImage
2. blink::WebClipboard::writeImage
3. content::WebClipboardImpl::writeImage
4. content:: RendererClipboardDelegate::WriteImage
 Send IPC: ClipboardHostMsg_WriteImage

Browser Process
5. content::ClipboardMessageFilter::OnWriteImage
6. ui::ScopedClipboardWriter::WriteImage(const SkiBitmap&)
 Do we need to pass original image format?
7. ui::Clipboard::WriteObjects
8. ui::Clipboard{Android,Aura,AuraX11,Mac,Win}::WriteObjects
9. ui::Clipboard::DispatchObject()
10. ui::ClipboardXXX::WriteBitmap(SkiBitmap*)

I believe for security there needs to be some validation of the content being stuffed on the clipboard.

According to the clipboard API spec,
https://w3c.github.io/clipboard-apis/#writing-to-clipboard

"image/svg+xml" is the only image format among those specified there,
and I'm not sure it is supported by Chrome.

It also means, standardization effort is also included in this issue?
I am curious if any of other browsers support exporting non "image/svg+xml"
image formats for Clipboard API.

We just write it as text/plain to workaround the svg limitation, but then callers have to parse the text to detect SVG.  That's not ideal in the long run.

I'm just amazed SVG/PDF and other vector formats can't be put on the clipboard.  These are images or hold images inside them, but web-based design tools need a mechanism to get these to other apps.  For now, PWA will just have to try to bypass the sandbox that restricts these reasonable interactions.

What is the current status of the work here? #66 suggests that we may need to do some standardization work to support additional image formats in the clipboard API. Is that correct or are we able to proceed with implementing?

If we can proceed, is there an owner we can move this bug to?

Last I heard, we were not comfortable letting sites write any image MIME types to the clipboard without sanitizing/re-rasterizing.

I don't know if that applies to SVG, although I imagine it would (SVG parsers can have vulns, too).

dcheng@ would know the latest.

Well, we allow webapps to put raw HTML into the clipboard, so I think we'd probably be semi-comfortable with SVG. We may still want to make sure "interesting" constructs are stripped out due to the XML representation though: a quick search for SVG XXE reveals a number of bugs, so emitting a filtered representation might not be a bad idea.

Thanks for this additional information! Would we be able to move forward with supporting all image types assuming that we added the filtering/re-rastering step? If so, @lgarron are you the one who would take on that work?

garykac: It seems that you're working on this.

We really don't want the images "sanitized" if they're coming from our content creation tool, or the user really needs the original metadata from the image that we put on the clipboard.  

At this point, though, I'll take anything other than having these filtered.  Allow application/pdf to be received on execcommand("paste"), and allow image/png, image/jpg, application/pdf, and image/svg+xml to be put onto the clipboard.  execcommand("copy") already works for SVG.

commit 9394e0a07007e81706e7257d75966e6c95af435b
Author: Darwin Huang <huangdarwin@chromium.org>

Async Clipboard: ReadImageExperimental/WriteImageExperimental

API Goal:
- Async Clipboard functionality to ReadImageExperimental() and WriteImageExperimental()
- JS layer will send Blobs with MIME type "image/png"
- Images will be "safe", as we'll re-encode to strip potentially dangerous
metadata and protect from arbitrary code execution. Only image types
supported by the Skia library will be supported for this initial POC.
- First release into experimental with this ReadImageExperimental()/WriteImageExperimental()
- Later integrate into Read()/Write() and remove ReadImageExperimental()/WriteImageExperimental()

Features:
- FileReader used to read Blobs asynchronously.
- Image Decoding on a separate thread.
- Image read/write accomplished, where Images are represented by Blobs holding
MIME type "image/png"

Just to make sure - reading images will not re-encode them, right (users can paste any file - unmodified I think - nowadays with the legacy clipboard API)? Only writing images to the clipboard will re-encode them, right?

Yes, that is the plan.

Async Clipboard: Integrate readImage/writeImage into generic read/write

- read/write now use Blobs instead of DataTransfer, and can only read/write one
type at a time.
- read/write can now read/write images in addition to existing text support.
- readImageExperimental and writeImageExperimental removed.
- Images will be encoded in the same manner as before this CL, whereas text
will be emitted with utf-8 encoding.
- read will prefer to return an image if one is available, and will return text
otherwise.
- Relevant tests updated.

Future Work:
- Use vectors or lists or some collection of Blobs to read/write many types at
a time, to work towards feature parity with DataTransfer.

Async Clipboard: Specify exceptions

- Previously, async clipboard promise rejections had no DOMException tied to
them. This CL adds exceptions for when async clipboard operations fail.
- These are simply mock exceptions until more precise exceptions are added into
the spec.

Async Clipboard: Read/Write Blob->sequence<Blob>

- read(Blob) updated to read(sequence<Blob>).
- write() returns sequence<Blob> instead of Blob now.
- All available and valid types are returned in read() or allowed for write().
- Tests updated and added for these API changes.

Also:
- Updated header file function ordering.
- Duplicate MIME types not allowed on write (consistent w/existing clipboard).

Async Clipboard: Update read/write to use a record instead of sequence

- Update read/write functions and tests to be closer to the future intended API
surface, as described by the explainer:
https://docs.google.com/document/d/1lpi3-9vBP_1b7hZc2xBs0s_HaACJ6UigZZqHlJSNeJg/edit

- Remove uniqueness checks, as the JS dictionary type will enforce this.

Async Clipboard: Split out Clipboard type-specific logic for Encoding/Decoding.

- clipboard-type-dependent code mostly split out to
ClipboardReader/ClipboardWriter.
- ClipboardWriter/ClipboardReader have two child/sub/derived classes,
one for images and one for text.
- Also did minor refactoring, like appending a '_' for the clipboard
promise's sequence checker and removing the clipboardtype member var.

Requesting permission to merge https://crrev.com/c/1567224 to M76. We missed the branch due to logistical issues (I didn't add a reviewer to the CL correctly), and this is a highly anticipated feature that was targeted for M76.

The CL enables a feature that has been available under the "Enable experimental Web Platform features" flag since M75, so we think that the code is solid and there are no crashers lurking in there.

This bug requires manual review: There is .json file changes and we are only 59 days from stable. Please confirm this does not require string translation.
Before a merge request will be considered, the following information is required to be added to this bug:

2. Links to the CLs you are requesting to merge.
3. Has the change landed and been verified on master/ToT?
4. Why are these changes required in this milestone after branch?
5. Is this a new feature?
6. If it is a new feature, is it behind a flag using finch?

Removing the Check-String-Translation label. This CL enables a Web Platform feature that has been code-complete since M75. Furthermore, the Web Platform feature  does not add new UI (confirmation prompts, etc.)

1. Does your merge fit within the Merge Decision Guidelines?
- Chrome:  https://goto.google.com/chrome-release-branch-merge-guidelines
Yes.
This CL enables a feature that has been available behind a flag since M75.

3. Has the change landed and been verified on master/ToT?
Yes

4. Why are these changes required in this milestone after branch?
We missed the branch by one day due to logistical issues. I intended to ask chrishtr@ to review the CL on 05/30 at 1pm [1], but didn't add the email to the reviewer list correctly. I only realized this on 05/31 at 6pm, and asked for a review then [2]. The CL landed on 05/31 [3]. This CL enables an API that has significant developer demand -- this bug currently has 1878 stars. The API was promised for M76, and we would like to deliver on that promise.

5. Is this a new feature?
No.

6. If it is a new feature, is it behind a flag using finch?
N/A

I'm sorry... I misread the approval email from https://crbug.com/968179#c13 and merged for this bug instead. I'll revert the CL above if the merge request here is denied.

Per https://crbug.com/chromium/150835#c112, this change is OK to merge to M76. Thank you for explanation and merge.

Removing "Merge-Approved-76" label as change is already merged to M76 at #113.

To all following this bug, it is now fixed (yay!).

Images may now be programmatically copied through use of the Async Clipboard API. This is exposed only as "image/png" for now, and all images are re-encoded for security purposes.

This will release in stable in M76, on 6/30.

This can also be enabled in M75 (released in stable tomorrow) through enabling the experimental flag (chrome://flags/#enable-experimental-web-platform-features), for those interested in seeing this API in action earlier.

For more information on the release dates: https://chromiumdash.appspot.com/schedule
For more information on the feature: https://groups.google.com/a/chromium.org/forum/#!topic/blink-dev/TssvWe8TzBc

(For those interested in raw (not-re-encoded) images, this work will be tracked in https://crbug.com/897289)
(For those interested in other image types, like image/jpeg, this work will be tracked in https://crbug.com/954390)

For developers visiting this bug from various links on the internet, this is already in Chrome Stable now. Here's an article detailing how to use the Async Clipboard API with image support: https://developers.google.com/web/updates/2019/07/image-support-for-async-clipboard

Retroactively bumping to P1 via the Fugu rubrik that we staffed this and have interested partners
