Retrieving Images from GetRenderList

[psycik]

Hi sub. A request from martin, is it possible to convert a GetRenderList back to a foreground/background image that I could then save to a file?

In the "old" days we were dealing with the images directly so it was pretty easy. What about for the new stuff or would this be some helper function that we could get you to add?

Basically I guess I want to ask for an image so i can save it, or know the method that you use to convert a render array list back to an image.

There isnt really a single image covering the whole screen. You'd have to make your own with something like:

Code:

Bitmap compositeRendering = new Bitmap(1280,720);
            Graphics g = Graphics.FromImage(compositeRendering);

            
            // draw each element from the render list to the appropriate place
            foreach (GBPVRUiElement uiElement in renderList)
            {
                int x1 = (int)((compositeRendering.Width / 100.0) * uiElement.oneOffRect.X);
                int y1 = (int)((compositeRendering.Height / 100.0) * uiElement.oneOffRect.Y);
                int width = (int)((compositeRendering.Width / 100.0) * uiElement.oneOffRect.Width);
                int height = (int)((compositeRendering.Height / 100.0) * uiElement.oneOffRect.Height);

                g.DrawImage(uiElement.image, new Rectangle(x1, y1, width, height));
            }

            compositeRendering.Save(Path.GetTempPath() + "\\pch.jpg");

Thanks sub I was hoping the DirectFB offered this type of ability so I could save the surface myself but I can't.

psycik could you try .Save in both png and jpg extensions I'd like to standardize on something with alpha capabilities if I can.

So martin, do you want the whole screen, or just the info panel from the bottom?

[mvallevand]

I'm just a dumb client, so whatever you save will be rendered full screen and your aspect ratio will not necessarily be preserved.

Doesn't seem to work too well, there must be something else sub is doing that I don't see.

Seems to miss/invert the backgrounds.

Considering this is supposed to be blue.

You just need to initially draw the background image, to fill the entire composite image, prior to drawing each item in the render list.

[psycik]

And to get the background image I'd have to figure out what my background image is called from he skin file, since at the moment I think you control that bit.

[sub]

You'll probably have to do something like use an instance of the SkinHelper2 object and call skinHelper.loadImageFromFile("Menu\\background.jpg"), or use the Image.LoadFromFile to load the same thing manually.

psycik could you implement this "as is" for the next test release? It will allow me to do some work on it and I might be able to tell if you are writing in the the overscan area.
