[webkit-dev] make failure due to libffi
Hi I am trying to port webkit to Microblaze. It goes well until almost the last step that it is building the libwebkit.la It needs to use libffi and there is no port of libffi for microblaze. I tried to do it my self but no luck. As far as I understood libffi is used in webkit for JavaScript. Is there any way that I can disable JavaScript when compiling and building webkit?

Re: [webkit-dev] Reading from Object
I think my issue some kind of lack of knowledge in C++. I'm trying to redesign the the text placement engine in webkit. For my purpose I need to get access to font face which is stored in the place I mentioned. I know that they are private but I want to read them, and I know it is possible to do so.

[webkit-dev] Text Box in Frame Layout
Hi I'm doing a redesign on text processing. Previously I have had some discussions on the mailing list but after all I couldn't find the start place where webkit starts the inline box for text. There is a place in rendering process where webkit sees that there is paragraph of text on the webframe and it needs to decide how big it will be to fit that text. It has the width and needs to calculate the height of that box. I want to know where is this place. Thanks for any help Soheil Servati Beiragh PhD Candidate, ECE Department, Research Center for Integrated Microsystems, University of Windsor.

[webkit-dev] WebKit port to my own system?!
I was wondering if there is any version or project of webkit that can be used to port on my own system? I mean a version that doesn't use GTK or...to access frame buffer.

Re: [webkit-dev] Font Name
I can add to this that If someone wants to work on text rendering and doesn't
want to deal with html or CSS parsing, he can find an index for the font family
under:
Font-m_fontDescription-m_familyList-m_family-m_Data.
I know for example that index for monospace family is 67 or for times new roman
is 84 but I still don't know if there is a table some where about all indexes
for font families.

Hi,
When you are drawing some text, you create a RenderText(RenderObject) which
has all the rendering info the m_style of RenderText has the style info
required to render the text.
Let's consider the following style data I have in my html page
style type=text/css
body.rahaman{
font:30px courier;
}
/style
body class=rahaman Rahaman /body
Once the HTMLTreeBuilder parses the token, it creates HTMLStyleElement
CSSStyleSheet then asks the CSSParser to parse the StyleSheet. From there it
comes to CSSParser::parseValue()=CSSParser::parseFont() as the I have only
used font property
We create a FontValue (which contain all the attribute a font property can
have like style, size, variant, family etc= in this font_family, you can
actually see the font name you have used ). In CSSParser::parseFont, we
populate the FontValue structure (you can find the font family name in
font-family), calls CSSParser::addProperty() where we create a CSSProperty
with the FontValue/CSSValue being passed this property is being stored in
CSSParser::m_parsedProperties.
Then we call CSSParser::createStyleRule where we used the m_parsedProperties
mentioned before to create a CSSMutableStyleDeclaration set this declaration
for the CSSRule.
We then create CSSStyleSelector and call CSSStyleSelector::styleForElement for
the root element. Here somehow (I don't have much details what happens in
berween but figured out that we retrieve the same CSSMutableStyleDeclaration
mentioned above) call CSSStyleSelector::applyProperty(). Here each
StyleSelector has its RenderStyle (m_style), where from we retrieve the
FontDescription add the properties accordingly. On the other hand, each
RenderObject (the corresponding node in the RenderTree for a node in DOM tree)
has RenderStyle, which gets the value we retrieved above.
Finally we call GraphicsContext::drawText() passing the Font which we have
retrieved from the RenderStyle we dsicussed above.
I am not sure if this is what you were looking for, I just shared whatever I
knew of the related area. Please let me know if you need anything else.
Thanks,
Rahaman

I joined the channel #webkit-efl but for now no luck. Any way... I'm working on a new text layout scheme for webkit That sounds like a bad idea... What do you mean by a new text layout scheme? Is it spec'd anywhere? Does any other browser do the scheme in question? How does it interact with CSS layout? and I needed to find out: 1. Does webkit renders bitmap glyphs before it starts to do layout or it just uses the data from font file for metrics? WebKit does not render glyphs. The platform's font system does. Source/WebCore/platform/graphics (and /text) have abstractions for taling to the various platform font systems. 2. If it does, where does it save the bitmap glyphs and if not where it saves the data from font file? Again, this is all handled by the underlying platform libraries. WebCore keeps a glyph cache. Where it caches glyph identifiers (pointers on some platforms) as well as some measurement information per-character. But it just hands those identifiers off to the platform again to do the drawing. 3. I need to find out where it gives the layout engine the size of the block for text and the position of the block on screen? This sort of information is calculated during layout() and stored on the RenderObjects. RenderBoxModelObject is the superclass for all RenderObjects which layout according to the CSS box model (which you can search for on google and read more about). Search for my name on YouTube to find a video describing some of this. Thanks for your attention Again, inventing a new layout scheme is probably a bad idea. Designing one in a research paper is fine, but you probably won't want to implement it... :) SVG Text has some of its own line layout. You'll need to learn more about the line box tree. (InlineBox and subclasses.) MathML also does some of its own layout modifications on top of CSS line layout. Best of luck.
