content_scaled_redraw()

bool content_scaled_redraw	(	struct hlcache_handle *	h,

Redraw a content with scale set for horizontal fit.

Redraws the content at a specified width and height with the content drawing scaled to fit within the area.

Parameters

h	The content to redraw
width	The target width
height	The target height
ctx	current redraw context

Returns

true if successful, false otherwise

The thumbnail is guaranteed to be filled to its width/height extents, so there is no need to render a solid background first.

Units for width and height are pixels.
