With some changes a couple of months ago, I made it possible to render HTML and QML content that does not use WebVfx-specific JavaScript extensions, but it renders those with an opaque background. Tonight, I did some poking around to see if I could extend that to the webvfx filter. I discovered it works already today in QML if you simply set the color of your background rectangle to "transparent" and preface the filename with "plain:" to tell WebVfx not to wait for a "ready" from JavaScript. I also found that with the simple addition of 3 lines in the C++ WebVfx code, I can make the default page color of HTML transparent. So, I am discussing that change with the WebVfx developer. I am quite excited about this as it will open up HTML and QML-based text and animation effects for video to many. -- +-DRD-+ ------------------------------------------------------------------------------ How ServiceNow helps IT people transform IT departments: 1.
