I have loaded an image in OpenGL by using texture. Now I want to draw same image after some time in future. So I keep texture for that image in my texture array. Now how can I load that image directly from that stored texture.

glBindTexture(GL_TEXTURE_…, textureID);

I am trying to copy an area (circle) on an image to another part of the image. (Like shown below)
Something similar is the CopyRect procedure. The only difference is the shape.
Create clipping region (CreateEllipticRgn here, CombineRgn for more complex figures)
Select it (SelectClipRgn) in destination device context (Canvas.handle).
Copy rectangle containing needed fragment. Parts outside clip region remain the same.
Remove clipping region

Does Direct2D support custom shaped windows? Say, drawing a circle over all other windows. If yes, could anyone give a link to an article or sample of such technique? Thanks.
Yep, it does.
Here is an article with examples, unfortunately, it goes in Russian, so use an online translator:

How can I remove the watermark of images?
Photoshop.
If you have an original image and the image with the watermark, you can subtract them to see what what watermark did. You can then subtract this watermark from other images. Note that this won't always work and will result in artifacts unless you know exactly how the watermark was applied.
