Bug 23458 – Reintroduce CanvasPixelArray in ImageData.idl

• Component: DOM
• Status: RESOLVED FIXED

[Ivan Posva]

Reintroduce CanvasPixelArray in ImageData.idl:

Recent changes to the ImageData.idl broke non-JSC bindings. This change reintroduces the CanvasPixelArray and for the JSC build defines it to be equivalent to WTF::ByteArray.

Ideally I would have wanted to use "#if defined(LANGUAGE_JAVASCRIPT) && !defined(JSC_BINDING)" as you suggested to Darin, but it appears that something like JSC_BINDING does not exist in the code generator.

Actually, on second thoughts, i think a better solution would be to make CanvasPixelArray be a subclass of ByteArray for those builds that need it -- all builds should be using WTF::ByteArray to ensure consistency, and just typedef-ing the type difference away could lead to platform inconsistencies

[Oliver Hunt]

Basically, my though is that ImageData should be in terms of WTF::ByteArray, but those builds that need to declare it as type CanvasPixelArray should have there own typedef

[Oliver Hunt]

Err, need to declare in IDL -- do we support typedefs in IDL files?

+#if !defined(LANGUAGE_JAVASCRIPT) || !defined(JSC_BINDING)
...
+#if !defined(LANGUAGE_JAVASCRIPT) || defined(V8_BINDING)

Is it intentional that the checks are different?
