Bug 33750 – Add back an AffineTransform class for use by SVG

• Status: RESOLVED
• Resolution: FIXED
• Component: SVG

[Sam Weinig]

SVG does not need the full generality of the TransformationMatrix class and could benefit from the AffineTransform class being added back and being used by SVG.

[Simon Fraser (smfr)]

Do you have any performance data to show that TransformationMatrix is an issue?

Stress test

We came to this conclusion looking at the attached stress test with 50,000 rects.  It seems every RenderPath has at least one TransformationMatrix.

[Dirk Schulze]

It is planned to introduce 3D transformations to SVG 2.0 (http://www.w3.org/TR/2009/WD-SVG-Transforms-20090320/). Even if we concentrate on SVG 1.1 at the moment, we might want to implement it later. Thus we should let TransformationMatrix in and try to optimize the use of it. olliej did allready a great step forward with bug 33766 and bug 30055.

reimplementation of AffineTransformation

After a discussion on IRC, all agreed to reimplement AffineTransform in a platform independent way. This is the first and implements AffineTransform and let Canvas make use of it. Next patches will introduce AffineTransform to SVG.

Looks like a style decission of the chromium guys and it makes sense here for a better code reading.

AffineTransform is also a primary header. The names of TransformationMatrix*.cpp might change to AffineTransform*.cpp later.

Gtk port uses underscores for variables.

It's necessary to check for 0 here, since values are allowed to be negative.

Found it that way in all other headers for operator like FloatPoint, Size, Rect as well as TransformationMatrix and others. Maybe also a false positive?

I can't speak to the other issues, but the chromium port is intended to be 100% in compliance with the WebKit style guide.  Any deviations are errors and should be corrected as convenient.

Did you take a look at the affected code part? I have no problem to fix it with an upcomming patch, but it makes more sense to have more spaces here.

Situations like that are actually called out specifically in the Google Style Guide (which agrees with the WebKit Style Guide on this point).

I don't mean to be the style enforcer.  I mostly wanted to make that comment for future reference.  Other platforms (e.g., Gtk, Qt) do use different style in parts of WebKit to match their respective platforms.  In the case of Chromium, we've changed the platform to match WebKit style (which is one reason it took a while to upstream the "glue" layer).

If you'd like to remove the whitespace, that would be great.  If you feel like other things are more deserving of your attention, that's fine too.  :)

I'm pretty sure, that it works on gtk. (Tested it with trunk on my own system)

I also run check-webkit-style. I got  warnings, all about == 0 checks. They were found in AffineTransform and are neccessary there.
