Hi Alp, I have used the comments mentioned in https://bugs.webkit.org/show_bug.cgi?id=14998, Comment #37 you provided for Zooming Using CSS in the following way void webkit_web_view_scale_transform(WebKitWebView *page,float factor) { WebKitWebFrame *webFrame = webkit_web_frame_new(page); Frame *frame = core(webFrame); TransformOperations transform; Document* document = frame->document(); HTMLElement* root = reinterpret_cast<HTMLElement*>(document->documentElement()); RenderObject* renderer = root->renderer(); RenderStyle* style = renderer->style(); transform.operations().append(ScaleTransformOperation::create(factor, factor, ScaleTransformOperation::SCALE)); style->setTransform(transform); renderer->setStyle(style); } This does not perform any Scaling operation and on invoking above function displays a blank page. I am new to WebKit, Kindly Guide! Thanks mwas
