Hi webkit-dev, You may have heard <http://youtu.be/aCdZIHBbRV0?t=1m26s> that Chrome for Android includes a "Font Boosting" feature. This is similar in intent to the text size adjust<http://developer.apple.com/library/ios/DOCUMENTATION/AppleApplications/Reference/SafariWebContent/AdjustingtheTextSize/AdjustingtheTextSize.html#//apple_ref/doc/uid/TP40006510-SW16>feature in Mobile Safari, that the QT port also seems interested in <http://webkit.org/b/73546>. Other mobile browsers have corresponding features: Mobile Firefox uses font inflation<http://dbaron.org/log/20111126-font-inflation>and IE Mobile applies text size adjustment<http://msdn.microsoft.com/en-us/library/ff462082(v=vs.92).aspx#sectionToggle2> .
Font Boosting increases the font size in wide blocks, so that you can easily read the text after double-tapping to fit the block to the screen, instead of having to zoom in further then scroll from side to side for each line you read. The details are subtle (since web text layout is complicated), and there's still a lot of tweaking to do. We chose to boost font sizes more than Mobile Safari (which has various limits), producing easily legible text, more in line with IE Mobile and Firefox Mobile. This is core functionality for mobile browsers, so we would like to upstream our implementation of Font Boosting to WebCore. We are keen to share code with other ports (e.g. QT and Mobile Safari) that are interested in this feature, and will be happy to incorporate suggestions on how to make this easier. I've opened webkit.org/b/84186 to track this effort. Best wishes, John
