Description Dirk Schulze 2010-10-19 13:12:21 PDT
I think we should merge the ColorSpace and ImageColorSpace enumerations. This mean adding linearRGB to ColorSpace and will be necessary for implementing color-interpolation as well as color-interpolation-filters on SVG.

Looks good overall, except for some minor things. But I'd really like to see whether we can avoid code duplication, by not using RetainPtr for the colorspace in ImageBuffer.

> WebCore/css/CSSPrimitiveValueMappings.h:2198
> +        default:

default is not added here on purpose, so the compiler warns if anything is missing. If you need to add sth. add the real case value.

> WebCore/platform/graphics/ColorSpace.h:34
> +    sRGBColorSpace,
> +    linearRGBColorSpace

I don't like these names, style guide says "Enum members should user InterCaps with an initial capital letter.".
So rename to SRGB and LinearRGB..

> WebCore/platform/graphics/cg/ImageBufferCG.cpp:83
> +    case DeviceColorSpace:
> +        m_data.m_colorSpace.adoptCF(CGColorSpaceCreateDeviceRGB());
> +        break;

Can you investigate, if it's possible to not use a RetainPtr for m_colorSpace. Then we could use the deviceRGBRef() static methods, instead of duplication code.

Other than that, looks good to me!

> WebCore/css/CSSPrimitiveValueMappings.h:2199
> +        ASSERT_NOT_REACHED();

You should comment here, that linearRgb is not available, through css "-webkit-color-correction". Otherwhise this is a bit confusing.

Looks great, r=me.
Please do a leaks run first, as I'm not 100% certain about the removal of RetainPtr for m_colorSpace. Looks fine according to the CoreGraphics docs though, but better be safe than sorry.
Comment 8 Dirk Schulze 2010-10-20 06:07:24 PDT
I checked. No leaks found. *Phew* ;-)
