[Chromium] Support HTML5 <progress> element on Linux.

• Component: Platform
• Status: RESOLVED FIXED

[Hajime Morrita]

Porting <progress> to Chromium Linux.
Note that chromium has platform-specific rendering code.
So we need bugs for each platform.

Please update WebKit source and regenerate the patch.

Could you split the patch into two parts? graphics/skia change and RenderThemeChromium* change.

WebCore/ChangeLog:12
 +          an image resampling mode. across multiple paintSkBitmap() calls.
You probably want to remove "." after "mode"?


WebCore/platform/graphics/skia/PlatformContextSkia.cpp:648
 +      const float kFractionalChangeThreshold = 0.025f;
We don't prepend "k" to constant values though I know you didn't write this code.


r- because of svn-apply failure.

Hi, Kent-san thank you for reviewing.
I updated and rebased the patch

> Could you split the patch into two parts? graphics/skia change and RenderThemeChromium* change.
OK. I split skia change out to Bug 40045, whose patch will come shortly.
Other feedback will be taken on that patch.

patch v1

WebCore/rendering/RenderThemeChromiumSkia.cpp:775
 +  static const int progressDeltaPixelsPerSecond = 100;
Please add comments about how did you determine these values.


WebCore/rendering/RenderThemeChromiumSkia.cpp:810
 +      return progressAnimationInterval*progressAnimationFrmaes*2; // "2" for back and forth
Add spaces around *.


WebCore/rendering/RenderThemeChromiumSkia.cpp:826
 +      paintInfo.context->drawTiledImage(barImage, renderObject->style()->colorSpace(), rect, IntPoint(0, 0), barTileSize);
We had better assign renderObject->style()->colorSpace() to a variable because it is used multiple times.


WebCore/rendering/RenderThemeChromiumSkia.h:126
 +          IntRect determinateProgressValueRectFor(RenderProgress*, const IntRect&) const;
We should make these internal functions to private or protected.
