http://www.w3.org/Bugs/Public/show_bug.cgi?id=13800 Summary: Add ArrayBuffer to Transferable types list (2.8.4); update Structured clone algorithm Product: HTML WG Version: unspecified Platform: PC OS/Version: Windows NT Status: NEW Severity: normal Priority: P2 Component: HTML5 spec (editor: Ian Hickson) AssignedTo: ian@hixie.ch ReportedBy: travil@microsoft.com QAContact: public-html-bugzilla@w3.org CC: mike@w3.org, public-html-wg-issue-tracking@w3.org, public-html@w3.org Depends on: 12586 In order to support suggested changes in CanvasPixelArray -> Uint8ClampedArray (per bug 12586), ArrayBuffer should be specified as a Transferable type in section 2.8.4. Furthermore, in the structured clone algorithm, the cloning of ImageData should be updated to allow the ImageData's Uint8ClampedArray to be transferred: Current text: ↪If input is a ImageData object Let output be a newly constructed ImageData object with the same width and height as input, and with a newly constructed CanvasPixelArray for its data attribute, with the same length and pixel values as the input's. Proposed change: ↪If input is a ImageData object Let output be a newly constructed ImageData object with the same width and height as input, and with a newly constructed Uint8ClampedArray view of the ArrayBuffer in the destination object of memory for its data attribute, with the same length and pixel values as the input's. ...or similar text to indicate that if the ImageData's Uint8ClampedArray's ArrayBuffer is transfered, then the new Uint8ClampedArray instance will be created over the transferred ArrayBuffer. -- Configure bugmail: http://www.w3.org/Bugs/Public/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
