Bug 18435 – Cairo build does not work as it is in the tree

• Component: Platform
• Status: RESOLVED FIXED

[Daniel Zucker]

Cairo build needs to remove functions WebFrame::spoolPages; DrawTextAtPoint; and createDragImageForLink since these require functionality not currently implemented in the Cairo configuration.

Can we move most of spoolPages down into WebCore? You should talk to Alp Toker, who I think was working on a cross-platform printing abstraction.

 void DrawTextAtPoint(CGContextRef cgContext, LPCTSTR text, int length, POINT point, const WebFontDescription& description, CGColorRef color, int underlinedIndex, bool drawAsPassword)
 {
+#if !PLATFORM(CAIRO)
     GraphicsContext context(cgContext);
 
     String drawString(text, length);
     if (drawAsPassword)
         drawString = drawString.impl()->secure(WebCore::bullet);
     WebCoreDrawTextAtPoint(context, drawString, point, makeFont(description), color, underlinedIndex);
+#else
+	notImplemented();
+#endif //!Platform(CAIRO)
 }

Seems like this whole function will have to be compiled out for Cairo, since you won't have a CGContextRef type.

I think we can/should rework WebDragClient to use the new ImageBuffer abstraction so that we can remove the CG-specific code from it.
