Question

I’ve compiled an application that uses WebKit on Leopard (10.5).

The application is 32 bit.
I’ve bundled 32 bit versions of WebKit/WebCore etc with the app.

If I run it on Snow Leopard (10.6) none of the CSS 3d transforms work. 3D transforms work in SL’s Safari.

I have a feeling that my app isn’t able to link with some of the 3D graphics frameworks in Snow Leopard. Are any of the graphic frameworks 64 bit only?

I ran into a similar problem. My goal was saving an image of a WebKit/WebView, but anything with -webkit-transform rendered blank.

This is the code I was using that did not work correctly:

-(NSBitmapImageRep *)getBitmap {
    return [[NSBitmapImageRep alloc] initWithFocusedViewRect: [[[[webView mainFrame] frameView] documentView] bounds]];
}

This code seems to fix the problem, indeed displaying objects with -webkit-transform:

-(NSBitmapImageRep *)getBitmap {
    NSBitmapImageRep *image = [webView bitmapImageRepForCachingDisplayInRect:[webView bounds]];
    [webView cacheDisplayInRect:[webView bounds] toBitmapImageRep:image];
    return image;
}
