I think you only use this in the .cpp

[dstockwell, 2013/08/27 05:02:02]

Done.

+
+namespace WebCore {
+
+class AnimatableImage : public AnimatableValue {
+public:
+    virtual ~AnimatableImage() { }
+    static PassRefPtr<AnimatableImage> create(StyleImage* image)
+    {
+        return adoptRef(new AnimatableImage(image));
+    }
+    PassRefPtr<CSSValue> toCSSValue() const { return m_image->cssValue(); }
+    StyleImage* toStyleImage() const { return m_image.get(); }

[Timothy Loh, 2013/08/27 04:26:06]

Maybe const StyleImage*?

[dstockwell, 2013/08/27 05:02:02]

no viable conversion from 'const WebCore::StyleImage *' to
'PassRefPtr<WebCore::StyleImage>

+protected:
+    virtual PassRefPtr<AnimatableValue> interpolateTo(const AnimatableValue* other, double fraction) const OVERRIDE;

+private:

+    {
+        ASSERT(m_image);
+    }
+
+    RefPtr<StyleImage> m_image;

[Timothy Loh, 2013/08/27 04:26:06]

Perhaps const RefPtr if possible.

[dstockwell, 2013/08/27 05:02:02]

Done.
