1278946 - Image data exists in dataTransfer when no image is present

Status: RESOLVED WONTFIX

(Core :: DOM: Events, defect)

Description

[Neil Deakin]

Attachment: Testcase

1. Open the attachment.
2. Select a text file from your filesystem (Finder) and copy it to the clipboard
3. Click on the blue paste box in the testcase
4. Paste there

Actual:
 - the test dumps out the contents of dataTransfer. The data includes image types, yet no image is present.

Expected:
 - just the file data should be present

Reproducable on Mac as least.

The data also includes all three image types (gif, png, jpeg) regardless of what type of image, if any, is actually provided by the clipboard.

Michael, can you please take a look?

The additional formats are present intentionally. The image data is transcoded to each of the different types for the application's convenience. If we want to only provide a single type (say PNG), that is a different matter.

With regard to copying files from finder to the clipboard, we currently don't support copying files. The images you are seeing on OSX are actually the icons for the file. Chrome also provides the PNG version of these icons to the website as well, so we should be web-compatible with this behavior (although it is unfortunate).

Closing as wontfix for now.
